David Peterson Injury News & Updates

Peterson underwent surgery Monday to repair the labrum in his left hip, Tim Healey of Newsday reports.

The Mets noted that the procedure usually takes 6-to-7 months to recover from, which means Peterson could miss roughly the first two months of next season. It's unclear how long the hip has been bothering Peterson, but it's possible it contributed to an up-and-down 2023 season which saw the lefty hold a 5.03 ERA and 128:50 K:BB over 111 innings. The Mets had already figured to be in the market for rotation help this offseason, and this news only reinforces that notion.

Peterson did not factor into the decision Thursday, allowing four runs on five hits and two walks over four innings against the Phillies. He struck out seven.

Peterson continues to rack up impressive strikeout totals, logging 37 in his last five starts (26.2 innings). However, he'd wind up with a no-decision Thursday, allowing a pair of runs in the first inning and another two in the third, as the left-hander remains winless since July 27. Overall, Peterson is 3-8 with a 5.37 ERA, 1.60 WHIP and 120:46 K:BB across 104 innings this season. He'll likely make one more start this season, currently scheduled for next week against Miami.

Peterson did not factor into the decision Friday, allowing three runs on six hits and two walks over 5.2 innings against the Reds. He struck out 10.

The 10 strikeouts matched a career high for Peterson, who has achieved that total on three other occasions. He pitched well but a two-run homer by Spencer Steer in the 6th inning was Peterson's ultimate undoing as he finished one out shy of a quality start. He lowered his season ERA to 5.52 and has 113 strikeouts in 100 innings. His next start is scheduled to take place during the Mets' upcoming road trip to Miami.

Peterson (3-8) took the loss Saturday, allowing three runs on eight hits and one walk over six innings against Minnesota. He struck out eight.

Peterson hit Donovan Solano with a pitch and then gave up a single to Jorge Polanco to open the bottom of the first before fanning the next three batters to get out of the jam. However, he would go on to allow three runs over the next two frames, which would ultimately decide the contest. The lefty has now allowed at least three runs and seven hits in three of his last four outings and has not recorded a win since July 27. On a positive note, he does hold a healthy 20:4 K:BB over his last three starts.

Peterson did not factor into the decision Saturday, allowing four runs on seven hits over four innings against the Mariners. He struck out four and did not issue any walks.

Peterson surrendered a solo homer in the first inning and two more runs in the third. He was removed with no outs in the fifth and a runner on base who would come around to score, giving Seattle a 4-3 lead and putting the southpaw on track for a loss until New York staged a late comeback. In six starts since rejoining the Mets' rotation Aug. 4, Peterson has posted a 4.15 ERA, 1.58 WHIP and a pedestrian 27:16 K:BB across 26 innings. He tentatively lines up for a road matchup with Minnesota next weekend.

Peterson did not factor into the decision Sunday, allowing a run on three hits and three walks over seven innings in a 3-2 victory over the Angels. He struck out eight.

Peterson matched a season high with eight strikeouts Sunday while shutting out the Angels until the seventh inning. It was an encouraging outing from the 27-year-old Peterson, who allowed four runs in just 4.2 innings in his last start against Atlanta. The southpaw lowered his ERA to 5.23 on the season with a 1.60 WHIP and 91:41 K:BB across 84.1 innings, including 16 starts. Peterson will look to build on his performance in his next outing, currently scheduled as a home matchup next week against Seattle.

Peterson did not factor into the decision Monday, allowing four runs on seven hits and two walks over 4.2 innings against Atlanta. He struck out four.

The 27-year-old southpaw endured yet another rough outing Monday, allowing a two-run double to Michael Harris and two solo home runs to Marcell Ozuna before exiting with two outs in the fifth inning. Peterson has failed to complete five innings in any of his three starts since rejoining the Mets' rotation on Aug. 9, posting a 5.25 ERA, 2.00 WHIP with a pedestrian 14:10 K:BB across 12 innings during that stretch. Assuming he gets another turn, Peterson is projected to face the Angels at home this weekend.

Peterson escaped with a no-decision Tuesday in the Mets' 7-4 loss to the Pirates, giving up one run on three hits and six walks over 3.2 innings. He struck out five.

The southpaw put runners in scoring position in each of the first three innings but was able to wriggle off the hook each time, and the only damage off Peterson came via a Liover Peguero solo shot to lead off the top of the second. It was still a rough outing for Peterson, who also plunked a batter and got just 48 of his 91 pitches over the plate. Since rejoining the rotation after the trade deadline, he's posted a 2.61 ERA that is far more lucky than good considering his 1.84 WHIP and 11:11 K:BB through 10.1 innings. Until he improves his control, Peterson will be an extremely volatile fantasy option. He's next set to take the mound this weekend in St. Louis.

Peterson allowed two runs on four hits and two walks while striking out five batters over 3.2 innings in a no-decision against the Cubs on Wednesday.

Peterson isn't fully built up after pitching out of the bullpen for most of July, so he was limited to 62 pitches and 3.2 frames Wednesday. The southpaw allowed a run in each of the first and second innings but kept the Mets in the contest, striking out five batters and allowing six baserunners. Peterson looks to have a rotation spot locked down with Justin Verlander and Max Scherzer no longer around, and he'll aim to extend further in his next start, which is scheduled to come at home against Pittsburgh early next week.

Peterson is slated to start Wednesday's game against the Cubs at Citi Field.

Peterson will be making his second straight turn through the rotation as a replacement for Max Scherzer, who was traded to the Rangers on July 29. Since he had been working out of the bullpen for nearly a month, Peterson was limited to just three innings and 52 pitches in his most recent start Friday against the Orioles. The lefty should be able to work longer into Wednesday's outing, though he still could struggle to reach the five innings he would need to qualify for a win.

Peterson came away with a no-decision Friday in the Mets' 10-3 loss to the Orioles, allowing one hit and three walks over three scoreless innings. He struck out one.

The southpaw tossed 30 of 52 pitches for strikes in the short outing, but considering he hadn't pitched more than two innings in an appearance in nearly a month, a restricted workload was to be expected. Peterson has a 2.66 ERA in 20.1 innings since the beginning of July, but that comes with a lackluster 1.43 WHIP and 19:11 K:BB, and the jury is still out on whether the 27-year-old will ever develop into an effective rotation option. He'll make his next start, and get stretched out further, at home against the Cubs next week.

Peterson is likely to start Friday in Baltimore, Mike Puma of the New York Post reports.

That would have been Max Scherzer's turn in the Mets' rotation, but he was traded to the Rangers on Saturday and is slated to make his debut for Texas this Thursday. Peterson, 27, has struggled to a 5.92 ERA and 1.62 WHIP in 11 starts and six relief appearances this season with New York.

Peterson will work out of the bullpen going forward, Will Sammon of The Athletic reports.

With the return of Jose Quintana from the 60-day injured list, Peterson will lose his spot in the rotation and be pushed into a multi-inning relief role. The 27-year-old southpaw has been hit around consistently this season and holds a 6.46 ERA and 1.64 WHIP through 54.1 frames across 11 starts.

Peterson (2-7) allowed three runs on five hits and two walks while striking out seven over 5.1 innings to take the loss Saturday versus the Padres.

Peterson gave up all three runs in the second inning, but the Mets' offense couldn't provide a sufficient response. He's allowed just three runs over 15.1 innings since his return to the big-league roster June 27, but his place in the rotation remains up in the air, likely hinging on when Jose Quintana (ribs) will be ready to make his season debut. Peterson has a 6.46 ERA, 1.64 WHIP and 60:22 K:BB over 54.1 innings this season.

Peterson allowed one run on three hits and three walks over four innings in Sunday's win against the Giants. He struck out three and did not factor in the decision.

Peterson gave up a run on a groundout in the third inning but otherwise looked solid in his short outing. He was demoted to Triple-A Syracuse in May after posting a terrible 8.08 ERA through 39 innings. The 27-year-old has coughed up just one run over 10 innings since returning to the MLB level, lowering his season ERA to 6.61. Peterson will likely stay in the rotation for another start, which is currently lined up to be in San Diego.

Peterson is listed as the Mets' probable starter for Sunday's game against the Giants at Citi Field.

The Mets will unsurprisingly stick with Peterson for another turn through the rotation after he tossed six shutout frames Tuesday against a Brewers offense that has languished versus left-handed pitching all season. The Giants, meanwhile, rank closer to the middle of the pack in most offensive metrics versus southpaws, so Peterson should have a slightly tougher matchup on his hands Sunday. Peterson's performance versus Milwaukee was arguably his best of the season, as he had posted an 8.08 ERA and 1.74 WHIP in eight starts for the big club prior to being optioned to Triple-A Syracuse in mid-May.

Peterson (2-6) picked up the win Tuesday versus Milwaukee after he allowed five hits and three walks across six scoreless innings. He struck out five.

The left-hander was called up from Triple-A Syracuse for his first big-league start in six weeks and delivered his best outing of the campaign. Peterson still showed signs of the struggles that resulted in him being sent to the minors in mid-May with three walks and just 11 swinging strikes on 110 pitches, but he consistently worked out of trouble against the Brewers. The 27-year-old still has a bloated 7.00 ERA, 1.69 WHIP and 50:17 K:BB across 45 innings this season, but the scoreless performance should be enough for him to garner another turn through the rotation.

The Mets recalled Peterson from Triple-A Syracuse ahead of his scheduled start Tuesday versus the Brewers at Citi Field.

Peterson is back in the big leagues for the first time since mid-May, stepping in as the Mets' new No. 5 starter after the struggling Tylor Megill was optioned to Syracuse last week. While spending the past five weeks in the minors, Peterson struck out 39 batters over 32 innings, but his other ratios (4.50 ERA, 1.50 WHIP, 12.9 BB%) during that six-start stretch weren't nearly as impressive. With Jose Quintana (rib) having now made three rehab starts in the minors and closing in on a return from the 60-day injured list, Peterson's stay in the New York rotation could be a brief one.

Peterson will be recalled from Triple-A Syracuse to start Tuesday against the Brewers, Mike Puma of the New York Post reports.

The left-hander has an 8.08 ERA in eight starts for the Mets this year and was demoted from the big-league rotation in mid-May. Peterson has a remarkable 4.86 ERA, 1.62 WHIP and 43:23 K:BB across 37 innings for Syracuse this year, but he'll receive another look in the majors since New York requires a fifth starter this week.

The Mets optioned Peterson to Triple-A Syracuse on Tuesday, Anthony DiComo of MLB.com reports.

Peterson struggled in another spot start Monday versus the Nationals and now stands 1-6 with a brutal 8.08 ERA through 39 innings of work this season at the MLB level. Josh Walker will join the Mets' bullpen in a corresponding move.

Peterson (1-6) took the loss Monday, allowing six runs on nine hits and two walks over five innings during a 10-3 loss the Nationals. He struck out five.

Peterson has struggled in his second stint in the big leagues this year, allowing 10 runs over two starts (8.1 innings) while posting a 9:4 K:BB. The left-hander wasn't much better the first time around, surrendering 25 runs over six starts (30.2 innings). Overall, he sports a 8.08 ERA and 1.74 WHIP, but his 45:14 K:BB across 39 innings is encouraging. With Max Scherzer healthy again and Carlos Carrasco (elbow) close to returning from the injured list, Peterson may be sent back to Triple-A Syracuse soon.

Peterson will make a spot start for the Mets on Monday versus the Nationals, Tim Britton of The Athletic reports.

This will allow an extra day of rest for Justin Verlander, who is now instead on tap for Tuesday's series opener against the Rays. Peterson struggled in an emergency start this past Tuesday versus the Reds, yielding four earned runs on seven hits and two walks over just 3.1 innings.

Peterson (1-5) took the loss Tuesday, giving up four runs on seven hits and two walks over 3.1 innings as the Mets fell 7-6 to the Reds. He struck out four.

The southpaw was sent down to Triple-A Syracuse at the end of April, but Peterson was brought back up after just one minor-league start when Max Scherzer (neck) wasn't able to take his turn. Peterson failed to capitalize on his second chance and needed 87 pitches to record only 10 outs, although he did avoid serving up any homers for just the second time in seven big-league outings this season. Peterson could remain in the Mets' rotation for now if Scherzer isn't ready to return over the weekend, or if the team simply wants to give the whole rotation an extra day of rest, but his 7.68 ERA and 1.68 WHIP don't make a compelling case to stick around for the long term.

Peterson was called up from Triple-A Syracuse and will start Tuesday versus the Reds, Pat Ragazzo of SI.com reports.

With Max Scherzer (neck) being scratched from his start Tuesday, Peterson will return to the big-league mound. Peterson has struggled to a 7.34 ERA and 1.57 WHIP with 36 strikeouts over 30.2 innings in six starts with New York this season. In a corresponding move that made room for the left-hander on the major-league roster, Jimmy Yacabonis (quad) was placed on the 15-day injured list Tuesday.

Peterson is meeting up with the Mets on Tuesday in Cincinnati, Michael Mayer of MetsmerizedOnline.com reports.

Peterson was supposed to start for Triple-A Syracuse on Tuesday, but it sounds like he's going to be the backup plan for the Mets in case Max Scherzer (shoulder) isn't ready to take his scheduled turn Tuesday night against the Reds. There should be more clarity on the situation soon enough.

Peterson was optioned to Triple-A Syracuse on Saturday.

Peterson has a strong 18.8 K-BB%, but it hasn't translated into strong run prevention. The southpaw had strong starts against the Marlins and Padres earlier in the year, but he gave up four or more runs in his other four starts. With Saturday's postponement and a potential postponement coming again Sunday against Atlanta, the Mets will have well-rested rotation options available early next week. Max Scherzer (suspension) and Justin Verlander (shoulder) will also return next week. John Curtiss was recalled from Triple-A in a corresponding move.

Peterson (1-4) took the loss Friday as the Mets fell 4-0 to Atlanta, giving up four runs on five hits and a walk over five innings. He struck out six.

For four innings the evening featured a pitchers' duel between two talented southpaws, but Atlanta got to Peterson in the fifth while New York's bats remained quiet against Max Fried, and they never got a chance to respond when the game was called after five frames due to rain. The long ball remains Peterson's Achilles heel this season -- Matt Olson's blast Friday was the eighth homer he's served up in 30.2 innings -- but his 36:10 K:BB offers hope he can turn things around if he hits his spots a little better. Peterson will take a 7.34 ERA and 1.57 WHIP into his next start, likely to come next week in Detroit.

Peterson (1-3) took the loss Saturday, allowing seven runs on seven hits and one walk over five innings during a 7-4 loss to San Francisco. He struck out eight.

Peterson allowed four runs in the first inning and two more in the second, but he was still able to get through five frames and struck out a season-high eight. The left-hander has given up at least five runs in three of his first five starts and currently sports a 7.36 ERA with a 30:9 K:BB through 25.2 innings.

Peterson (1-2) earned the win over the Dodgers on Monday, allowing six runs on seven hits and no walks while striking out six batters over six innings.

Peterson didn't pitch particularly well in the outing, yielding three homers, including two by Freddie Freeman. However, he managed to hang around for six innings and got enough run support to pick up his first win of the campaign. Peterson punched out six batters for the second straight time, and he recorded a healthy 14 swinging strikes among his 94 total pitches. The left-hander has yet to find consistency this season, alternating good and bad starts through four appearances. All told, he has an uninspiring 6.10 ERA, 1.65 WHIP and 22:8 K:BB across 20.2 frames.

Peterson (0-2) took the loss Tuesday, giving up two runs on six hits and two walks over 5.2 innings as the Mets fell 4-2 to the Padres. He struck out six.

The southpaw blanked San Diego for four innings before Manny Machado brought home two in the fifth with a double, but the New York offense couldn't get much going on the night. Peterson tossed 63 of 89 pitches for strikes before exiting, and he'll take a 4.91 ERA and 16:8 K:BB through three starts and 14.2 innings into his next outing, likely coming early next week on the road against the Dodgers.

Peterson didn't factor into the decision in Wednesday's 7-6 loss to the Brewers, surrendering five runs on five hits and five walks over four-plus innings. He struck out five.

The Mets' offense woke up and saved Peterson from a loss, but the left-hander was far from sharp, tossing 49 of 92 pitches for strikes and getting hit hard when he was in the strike zone. The 27-year-old's spot in the rotation is secure due to all the injuries on New York's staff, but through two starts he has a 6.00 ERA and 10:6 K:BB in nine innings. Peterson's next start is set for early next week, at home against the Padres.

Peterson (0-1) took the loss Friday as the Mets fell 2-1 to the Marlins, allowing one run on eight hits and a walk over five innings. He struck out five.

The southpaw tossed 51 of 84 pitches for strikes in his first outing of the season, but a second-inning solo shot by Jorge Soler put the Mets in an early hole they never climbed out of. Peterson could get a lengthy run in the rotation with both Justin Verlander (lat) and Jose Quintana (ribs) on the IL, and he'll look for a little more run support in his next start, likely to come Wednesday in Milwaukee.

The Mets informed Peterson on Monday that he will open the season as their No. 5 starter, Jon Heyman of the New York Post reports.

Peterson secured the final spot in the Mets' season-opening rotation over Tylor Megill, after both entered a competition for the role when Jose Quintana suffered a rib cage stress fracture in the spring that will keep him sidelined until at least July. Though he exhibited some control problems in spring training -- Peterson walked eight batters over 12 innings -- he didn't allow a run in Grapefruit League play and held opposing hitters to a minuscule .028 average while striking out 13. The southpaw was solid while floating between the rotation and bullpen in 2022 (3.83 ERA, 1.33 WHIP, 126:48 K:BB in 105.2 innings), and now that he has a clear path to a starting role for the foreseeable future, he'll make for an appealing late-round target in leagues that have yet to draft.

Peterson gave up one hit and four walks over four scoreless innings during Sunday's Grapefruit League game against the Cardinals. He struck out four.

The left-hander wasn't exactly sharp, throwing 40 of 66 pitches for strikes, but he was able to escape every jam his control issues created. More importantly for Peterson's chances of beginning the season in the Mets' rotation, Tylor Megill also pitched Sunday and had a much worse outing. Peterson posted a 3.86 ERA, 1.34 WHIP and 110:41 K:BB over 19 starts (91 innings) as a starter last year, and at this stage he appears to be the clear favorite to win the No. 5 spot in the rotation.

Peterson is starting Sunday's Grapefruit League game against the Astros.

Peterson will get the start, and Tylor Megill will follow for the Mets in the spring affair. Both arms are battling for one of the final spots in the New York rotation, and their efforts Sunday will at least play a part in determining who ends up being a part of that group to open the year.

Peterson walked one and struck out five over four scoreless, no-hit innings in Tuesday's Grapefruit League game against the Nationals.

With Jose Quintana (ribs) projected to be out until around the All-Star break, there's an opening in the Mets' rotation, and the competition for it is fierce. Tylor Megill fired four scoreless innings against the Marlins on Monday with three strikeouts, but Peterson topped that Tuesday with a brilliant performance over 68 pitches (41 strikes) against a Washington lineup that contained a handful of Opening Day starters, including CJ Abrams, Keibert Ruiz and Corey Dickerson. Peterson might have the edge over Megill right now simply by virtue of the fact that he'd be the only southpaw in the New York rotation, but this battle could come right down to the wire.

Peterson (foot) will start Tuesday's Grapefruit League game against the Nationals.

Peterson made his second and most recent appearance of the spring March 4, but after taking a comebacker off his left foot in that outing, the Mets elected to delay his re-entry into the pitching schedule out of an abundance of caution. The southpaw's foot appears to have checked out fine following his most recent throwing sessions, so he'll get back on the hill Tuesday and could build up to 3-to-4 innings. Peterson's health and availability takes on added importance after Mike Puma of the New York Post reported Monday that starter Jose Quintana (rib) is expected to be shut down for the next three months, though Puma notes that team officials are intrigued by the idea of giving right-hander Tylor Megill the first crack at replacing Quintana in the rotation.

Peterson (foot) could be behind Tylor Megill in the pecking order for a rotation spot with the Mets following Jose Quintana's (rib) injury, Mike Puma of the New York Post reports.

Peterson has missed a little time this spring with a foot contusion (he could return Tuesday), but this seems to be more about the team viewing Megill as having more upside. Quintana is expected to be sidelined until around the All-Star break, so the Mets figure to wind up needing both pitchers, anyway. Peterson held a 3.83 ERA with 126 strikeouts in 105.2 innings in 2022 and is worthy of a late flier in fantasy leagues even if he doesn't start the year in the rotation.

Peterson (foot) threw a bullpen session Saturday and could pitch in Tuesday's Grapefruit League game against the Nationals, Tim Britton of The Athletic reports.

The 27-year-old has now thrown off a mound twice since being struck in the left foot by a comebacker March 4, and he could make his return to game action this week. Assuming he avoids any setbacks, Peterson should have a chance to secure a spot in New York's Opening Day rotation with Jose Quintana (ribs) out indefinitely and Kodai Senga (finger) also banged up.

Peterson (foot) threw live batting practice without issue Thursday in Mets camp, Anthony DiComo of MLB.com reports.

Peterson would have been an option to start Thursday afternoon's exhibition game against Team Venezuela, but the Mets wanted to keep him in a more controlled environment after he took a comebacker off his left foot in a Grapefruit League outing over the weekend. All is well, per manager Buck Showalter. Peterson, 27, is slated for the season-opening rotation in Queens with Jose Quintana sidelined indefinitely due to a rib fracture.

Peterson said he's fine Tuesday after taking a comebacker off his left foot during a Grapefruit League start Saturday, Anthony DiComo of MLB.com reports.

It's encouraging news given that Peterson now appears to be in the running for a spot in the Mets' season-opening starting rotation after Jose Quintana was diagnosed Monday with a stress fracture in his left ribcage. Peterson, 27, worked to a solid 3.83 ERA with 126 strikeouts in 105.2 innings (19 starts, nine relief appearances) last year for New York. He's worthy of late-round consideration in most fantasy drafts with a path toward an elevated role.

Peterson (foot) is an option to join the Mets' rotation if Jose Quintana (rib) needs to miss time, Mark W. Sanchez of the New York Post reports.

Peterson is dealing with an injury himself, although his foot issue appears to be minor after a CT scan showed only a contusion. The left-hander showed flashes of being a mixed-league asset last season, finishing with a 3.83 ERA and 126 strikeouts over 105.2 innings while splitting time between the rotation and bullpen. Tylor Megill would also be in the mix to replace Quintana.

Peterson has been diagnosed with a left foot contusion and is considered day-to-day, Abbey Mastracco of the New York Daily News reports.

Peterson's X-rays on his left foot came back inconclusive, and he underwent a CT scan on Sunday. The left-hander was struck in the foot during Saturday's Grapefruit League appearance against the Marlins before exiting. Peterson may need to miss a few days while recovering from the bruise, but barring setback he should be ready to go for the start of the regular season after avoiding a serious injury.

X-rays were inconclusive on Peterson's left foot, Tim Healey of Newsday reports.

Peterson was then sent for a CT scan, the results of which are not yet available. He was struck in the foot by a batted ball during Saturday's Grapefruit League game against the Marlins. More should be known by Monday.

Peterson will undergo X-rays after being struck on his left foot by a batted ball in Saturday's exhibition contest, Tim Healey of Newsday reports.

Peterson tossed 2.0 innings in Saturday's contest, but he also picked up the injury along the way. Expect the Mets to release another update on his status after the results of his exam have been read.

Peterson is expected to be in the mix as part of a six-man rotation the Mets plan to use at points this season, Tim Britton of The Athletic reports.

The team will utilize a traditional five-man setup for most of the season, but the plan is to insert a sixth starter during long stretches with no days off. That means both Peterson and Tylor Megill could wind up making a handful of starts even if everyone stays healthy (which, of course, is unlikely). It makes sense both because it will give the regular starters extra rest but also because Peterson and Megill on paper look like two of the better sixth/seventh starters in baseball.

Peterson will be stretched out as a starter in spring training, indicating he could begin the regular season in the rotation at Triple-A Syracuse, Anthony DiComo of MLB.com reports.

The Mets have five veteran starters on guaranteed contracts, which means when everyone is healthy, depth options like Peterson with either work out of the big-league bullpen or get stashed in Syracuse. As Peterson has minor-league options remaining, the latter route seems more likely to begin the season. The 27-year-old southpaw made 28 appearances (19 starts) for the Mets in 2022 with a career-high 27.8 percent strikeout rate and solid 3.64 FIP, and he could be the first pitcher called upon should injuries hit the rotation.

Peterson will be moved to the Mets' bullpen within the next few days, Anthony DiComo of MLB.com reports.

Peterson will head to the bullpen once Max Scherzer (oblique) makes his return to New York's rotation Monday. Peterson has allowed 11 earned runs over 9.1 innings since the beginning of September and could be used in more low-leverage situations out of the bullpen until he's able to regain command over his pitches.

Peterson (7-5) took the loss Wednesday, allowing five runs on two hits and three walks over one-third of an inning in a 6-3 loss to the Cubs. He struck out one.

Peterson's disastrous outing began with three straight walks and ended with back-to-back two-run doubles from Yan Gomes and PJ Higgins. The lefty had not allowed four runs or more in 11 straight starts, his last such outing coming June 15 when he allowed four in four innings against Milwaukee. During that 11-start span, the 27-year-old recorded seven strikeouts or more eight times.

Peterson (7-4) took the loss Friday, giving up three runs on five hits and two walks over 3.2 innings as the Mets fell 6-3 to the Marlins. He struck out seven.

The strikeouts salvaged some fantasy value for the lefty, but Peterson wasn't sharp, tossing 44 of 78 pitches for strikes and serving up three extra-base hits including a first-inning homer by Garrett Cooper. Peterson has lasted six innings only once in five starts since the beginning of August but hasn't pitched badly, posting a 3.24 ERA, 1.44 WHIP and 31:8 K:BB through 25 innings over that stretch.

Peterson is scheduled to start Friday's game in Miami.

Peterson looked to be on the outs for a rotation spot after Carlos Carrasco returned from the 15-day injured list last weekend, but the 27-year-old southpaw will end up maintaining a starting role after Max Scherzer (oblique) was placed on the shelf just a few days later. Over his six appearances (four starts) for the Mets in the second half, Peterson has turned in a 3.57 ERA, 1.50 WHIP and 26:8 K:BB across 22.2 innings.

Peterson didn't factor into the decision in Friday's 7-3 win over the Nationals, giving up three runs on eight hits and a walk over 5.1 innings. He struck out six.

The southpaw tossed 58 of 95 pitches for strikes in a solid outing, but the Mets' offense didn't take the lead for good until the bottom of the sixth inning. Peterson has a 3.38 ERA, 1.44 WHIP and 19:3 K:BB through 16 innings over his last three starts, but with Carlos Carrasco (oblique) set to rejoin the rotation Sunday, he could move into a long relief role over the final weeks of the season.

Peterson (7-3) allowed four hits and struck out seven without walking a batter in six shutout innings to earn the win Saturday over the Rockies.

Peterson took an inefficient loss in the second game of last Saturday's doubleheader versus the Phillies, but he was good in this start against the hapless Rockies. He didn't give up an extra-base hit and kept Colorado from putting a runner in scoring position after the first inning. Peterson lowered his ERA to 3.21 with a 1.28 WHIP and 104:40 K:BB through 89.2 innings across 20 appearances (16 starts). He could stick in the rotation for another turn since Carlos Carrasco (oblique) is more than a week away from returning. If Peterson gets another turn, he lines up for a favorable home start versus the Nationals next weekend.

Peterson was recalled from Triple-A Syracuse ahead of Saturday's start against the Rockies, Mike Puma of the New York Post reports.

Peterson started the second game of a doubleheader against the Phillies last Saturday and gave up three runs on eight hits and two walks while striking out six in 4.2 innings to take the loss. He'll make at least one more turn through the rotation, and it's possible that he remains with the big-league club until Carlos Carrasco (oblique) is cleared to return.

The Mets will call up Peterson from Triple-A Syracuse to have him to start Saturday's game against the Rockies at Citi Field, Tim Healey of Newsday reports.

Because he was designated as the Mets' 27th man in advance of his start in the second game of last Saturday's doubleheader with the Phillies, Peterson had to be returned to the minors following the outing in what amounted to a procedural move. The Mets will still need to make a corresponding transaction to bring Peterson back this weekend, but he'll be stepping into the rotation on a more permanent basis while Carlos Carrasco (oblique) is likely sidelined until around mid-September. Peterson owns a 3.44 ERA, 1.33 WHIP and 97:40 K:BB across 83.2 innings in the majors this season.

The Mets optioned Peterson to Triple-A Syracuse following Saturday's doubleheader with the Phillies, Tim Britton of The Athletic reports.

Because he was designated as the Mets' 27th man for the twin bill, Peterson will temporarily move off the active roster after he struck out six and allowed three earned runs over 4.2 innings en route to taking the loss in Game 2 of Saturday's twin bill. As Britton notes, Peterson had to be designated as the 27th man in order to rejoin the Mets since he hadn't spent the minimum 15 days in the minors following his Aug. 6 demotion, but he'll still be eligible to be recalled later this week when New York requires a new fifth starter to replace the injured Carlos Carrasco (oblique). Unless the Mets decide to take advantage of Wednesday's off day to get by with a four-man rotation during the upcoming week, Peterson should rejoin the Mets to make a start next weekend against the Rockies at Citi Field.

Peterson (6-3) allowed three earned runs on eight hits and two walks while striking out six across 4.2 innings to take the loss in the second game of Saturday's doubleheader against the Phillies.

Peterson was called up from Triple-A Syracuse prior to the start, and he should stick in the rotation thanks to the absence of Carlos Carrasco (oblique). He didn't have his best performance against the Phillies, though he managed to strand three runners in scoring position to avoid any further damage. Peterson entered the game having allowed fewer than three earned runs in seven of his last nine starts while maintaining a 56:18 K:BB across 39 frames, so he should experience more success moving forward.

Peterson was added as the 27th man for Saturday's doubleheader against the Phillies, allowing him to start in the nightcap, Mike Puma of the New York Post reports.

Peterson has been quite effective for the Mets this season, striking out 27.2 percent of opposing batters en route to a 3.30 ERA in 14 starts and four relief appearances. He hasn't been needed in the rotation since Jacob deGrom returned from a shoulder injury, but he remains the top name the Mets will turn to whenever they need a spot start.

Peterson will be recalled to start Game 2 of Saturday's doubleheader against the Phillies, Tim Britton of The Athletic reports.

The left-hander picked up the win with 5.1 scoreless frames in a spot start Aug. 6 against Atlanta, and he'll rejoin the big club Saturday for the twin bill. Peterson has been an effective rotation option for the Mets in 14 starts this year with a 3.17 ERA, 1.23 WHIP and 83:33 K:BB over 71 innings.

Peterson was optioned to Triple-A Syracuse after the first game of Saturday's doubleheader, Anthony DiComo of MLB.com reports.

The left-hander was excellent in the matinee, holding Atlanta to three hits and three walks over five scoreless innings to improve to 6-2 on the season. He struck out five. Chances are, Peterson will be back the week of Aug. 15, in time for New York's next twin bill.

Peterson was called up by the Mets on Saturday to start the first game of a doubleheader against Atlanta, Tim Healey of Newsday reports.

Peterson has made 13 starts and four relief appearances for the Mets this season and has largely been an effective pitcher. Career highs in strikeout rate (27.5 percent) and groundball rate (53.8 percent) have helped offset a poor 11.2 percent walk rate, leading to a 3.54 ERA. The Mets likely won't need him to remain in the rotation after his Saturday spot, but it's possible he retreats to the bullpen rather than the minors.

Mets manager Buck Showalter said Peterson will be called up from Triple-A Syracuse to start one game of Saturday's doubleheader with Atlanta at Citi Field, Will Sammon of The Athletic reports.

New York is likely to designate Peterson as the 27th man for the twin bill, meaning that he's expected to be sent back to Syracuse immediately after the start. Though Peterson should make for a decent streaming option in deeper leagues after submitting a 3.54 ERA, 1.29 WHIP and 86:35 K:BB in 73.2 innings with the big club earlier this season, Jacob deGrom's return to the rotation Tuesday means that the Mets won't have a permanent spot for the 26-year-old lefty now that the team's top five starters are all healthy again.

Peterson was optioned to Triple-A Syracuse on Friday, Mike Puma of the New York Post reports.

Peterson wasn't listed as a starter for any games during the Mets' weekend series against Miami, and he'll ultimately head to the minors with Jacob deGrom (shoulder) on track to make his season debut next week. Peterson posted a 4.64 ERA and 1.41 WHIP in 21.1 innings over six outings in July and will be a candidate for a call-up if the Mets need an additional starter at some point.

Peterson isn't listed as a starting pitcher for any of the Mets' next four games, Tim Healey of Newsday reports.

As a result of off days Monday and Thursday, the Mets are shortening their rotation to four men this week. Taijuan Walker took the mound for Tuesday's win over the Yankees, while Max Scherzer will take the hill in Wednesday's series finale on four days' rest. The Mets will then have Chris Bassitt, Carlos Carrasco and Walker pitch in their three games in Miami this weekend, leaving Peterson to work out of the bullpen like he did in last weekend's series with the Padres. New York will require a fifth starter beginning with next week's series in Washington, but Jacob deGrom (shoulder) looks like he'll be ready to return from the 60-day injured list to make his season debut by then. Unless the Mets lose another starter to an injury or if manager Buck Showalter expands the rotation to six men, Peterson looks like he'll be the odd man out.

Peterson gave up one unearned run on three hits and three walks while striking out eight over five innings in a 3-2 loss to the Cubs on Sunday. He did not factor into the decision.

Peterson took advantage of the Cubs sub-par lineup by racking up eight strikeouts over five innings of work. The 26-year-old left-hander found himself in a bases-loaded jam in the fourth after a fielding error by Eduardo Escobar on a tailor-made double play ball, but he got out of the inning by leaning on his slider to induce a couple of swinging strikeouts. Peterson's slider has tons of movement and opponents are only hitting .145 against it in 2022. Look for him to make another start sometime after the All-Star break.

Peterson (5-2) took the loss Tuesday in Atlanta, allowing two runs on two hits and three walks while striking out nine in 5.1 innings.

Peterson cruised through the first five innings, holding Atlanta scoreless and allowing just a hit and two walks. After striking out Ronald Acuna to begin the sixth he issued a walk and gave up a two-run homer to Matt Olson and was removed from the game. Over his last two starts, the lefty has fanned 16 and walked eight in nine innings of work. If he starts again before the All-Star break it would be Sunday against the Cubs.

Peterson didn't factor into the decision in Wednesday's 8-3 extra-inning win over the Reds, giving up three runs on four hits and five walks over 3.2 innings. He struck out seven.

The strikeouts helped salvage some fantasy value for the southpaw, but Peterson struggled to find the plate consistently, tossing only 51 of 93 pitches for strikes. He was on the hook for his second loss of the year until the Mets rallied in the ninth inning. New York will get Chris Bassitt (COVID-19) back this weekend, but Trevor Williams is the more likely pitcher to get bumped from the rotation despite this poor outing from Peterson, who still sports a 3.48 ERA, 1.27 WHIP and 67:27 K:BB through 62 big-league innings this season.

The Mets reinstated Peterson (personal) from the paternity list ahead of his scheduled start Wednesday against the Reds in Cincinnati, Tim Healey of Newsday reports.

Peterson was away from the team for the maximum three days while observing the birth of his child, but he hadn't been in line to start in any of the Mets' games during that stretch anyway. He'll return to the mound on his normal four days' rest after he delivered one of the best starts of his career last Friday, when he struck out a season-high 10 batters while giving up three earned runs across six innings in a win over the Rangers.

Peterson (paternity) will start Wednesday against the Reds, Anthony DiComo of MLB.com reports.

Peterson left the team following the birth of his child, but he will not wind up missing a turn through the rotation. He will look to pick up where he left off after posting a 2.45 ERA, 0.93 WHIP and 25:2 K:BB in 18.1 innings over his last three starts.

Peterson will be placed on the paternity list Sunday, Anthony DiComo of MLB.com reports.

Peterson started Friday's game against the Rangers and allowed three runs on five hits and no walks while striking out 10 in six innings to earn the win. The southpaw left the team Saturday, but the Mets will wait at least one additional day to officially make a transaction since players can spend a maximum of three days on the paternity list.

Peterson (5-1) earned the win Friday, allowing three runs on five hits and zero walks over six innings against the Rangers. He struck out 10.

Peterson was bumped up to start Friday after Chris Bassitt landed on the COVID-19 injured list, though he was on full rest. The left-hander ended up matching his career high with 10 strikeouts, working around a couple solo homers en route to his fifth win of the season. Peterson has allowed a total of five earned runs in his last three starts with a sparkling 25:2 K:BB in 18.1 innings over that span. He told Deesha Thosar of the New York Daily News after the game that he will likely go on the paternity list Saturday.

Peterson will start Friday against the Rangers after Chris Bassitt was placed on the injured list without a designation, Anthony DiComo of MLB.com reports.

While it's short notice for Peterson, he will be on normal rest, having last pitched June 26. He went seven innings and fanned a season-high eight batters in his last outing and now has a 3.18 ERA, 1.32 WHIP and 27:9 K:BB over his last five appearances (22.2 innings). The lefty will be matched up opposite Glenn Otto in Friday's contest.

Peterson allowed two runs on four hits and no walks while striking out eight in seven innings during Sunday's loss to the Marlins. He didn't factor into the decision.

Peterson posted his second quality start of the season while striking out a season-high eight batters during Sunday's matchup, but he was unable to pick up the win during the low-scoring game. The southpaw has made seven appearances (six starts) since rejoining the major-league roster and has posted a 3.78 ERA and 1.32 WHIP in 33.1 innings during that time. He tentatively lines up to make his next start at home against the Rangers on Saturday.

Peterson allowed six hits and two walks over 5.1 scoreless innings Monday, striking out seven and earning a win over the Marlins.

Peterson faced several brief threats from the Marlins but still managed to turn in his first shutout performance since April 17 against Arizona. Since re-joining the big-league roster May 23, the 26-year-old is 3-1 with a 4.10 ERA through 26.1 frames. He lowered his season ERA to 3.18 with a 42:22 K:BB across 10 MLB appearances. Peterson is projected to face Houston at home next week.

Peterson (3-1) allowed four runs on six hits and two walks with three strikeouts in four-plus innings, taking the loss Wednesday versus the Brewers.

Peterson got through four innings in relatively good shape, but he didn't have anything left in the fifth as the Brewers built up a seven-run rally. He was only responsible for the first of those runs, limiting the damage on his line as reliever Jake Reed struggled the most. Peterson now has a 3.60 ERA, 1.33 WHIP and 35:20 K:BB across 40 innings in nine appearances (seven starts). The 26-year-old still has a tenuous grasp on a spot in the rotation, though he should get another turn in the rotation at home versus the Marlins next week. He's the most likely candidate to move to the bullpen once Max Scherzer (oblique) is ready to return.

Peterson is listed as the Mets' scheduled starting pitcher for Wednesday's game against the Brewers in New York.

Peterson's role became uncertain last week following Tylor Megill's (biceps) return from the 10-day injured list, which meant that either Peterson or Trevor Williams would lose out on a rotation spot. Both Peterson and Williams appeared out of the bullpen in the weekend series with the Angels while the Mets temporarily got by with a four-man rotation, but Peterson looks like he'll end up sticking as the No. 5 starter over Williams, who isn't included on the team's upcoming pitching schedule. Through his eight appearances (six starts) with the big club this season covering 36 frames, Peterson has generated a 3.00 ERA, 1.25 WHIP and 32:18 K:BB.

Peterson (3-0) picked up the win in Friday's victory over the Angels, allowing one run on three hits and a walk over 2.2 relief innings. He struck out three.

Entering the game in the fourth inning after Tylor Megill hit his pitch limit in his return from a biceps strain, Peterson inherited a 4-2 lead and made sure the Angels couldn't tie things up. The southpaw appears headed for a long relief role or even a return to Triple-A Syracuse now that the Mets' rotation is beginning to get healthier, despite a solid 3.00 ERA, 1.25 WHIP and 32:18 K:BB over 36 big-league innings this season.

Peterson didn't factor into the decision during Saturday's 9-4 victory over the Dodgers, allowing four runs (one earned) on two hits and four walks with six strikeouts in 3.2 innings.

Peterson exceled aside from the second inning, when a Pete Alonso error extended the inning and allowed three more runs to score. The 26-year-old struggled with his command again -- throwing 50 of 90 pitches for strikes -- and has now surpassed five innings in just two of his seven starts though New York has won six of those games. Peterson will take a 2.97 ERA and 1.23 WHIP into his next start, scheduled for next weekend against the Angels.

Peterson didn't factor into the decision in Monday's 13-5 win over the Nationals, giving up four runs on six hits and four walks over 4.2 innings. He struck out one.

Despite massive run support, Peterson wasn't efficient enough to quality for a win, getting the hook after tossing only 44 of 88 pitches for strikes and loading the bases with two outs in the fifth inning. Injuries to the likes of Max Scherzer (oblique) and Tylor Megill (biceps) should keep the southpaw in the Mets' rotation for now. but Peterson's 5.17 ERA, 1.34 WHIP and 13:8 K:BB through three starts and 15.2 innings in May don't make him a priority waiver add.

Peterson is slated to start Monday's game against the Washington at Citi Field, Mark Zuckerman of MASNSports.com reports.

With Jacob deGrom (shoulder), Max Scherzer (oblique) and Tylor Megill (biceps) all stuck on injured list for at least another week, Peterson always appeared likely to receive more than one turn through the rotation following his promotion from Triple-A Syracuse on May 23. He passed his first test in a tough road start in San Francisco, limiting the Giants to two runs while striking out six over six innings en route to capturing a win. Peterson will line up for two starts this week, with his second turn scheduled to come next Saturday on the road against the Dodgers.

Peterson (2-0) earned the win over San Francisco on Monday, allowing two runs on three hits and one walk while striking out six over six innings.

The southpaw was recalled from Triple-A prior to the game as the Mets look to fill the rotation hole caused by the recent injury to Max Scherzer (oblique). Peterson was up to the task against the Giants, yielding two runs in the second inning but otherwise putting zeroes on the scoreboard. He threw 57 of 99 pitches for strikes en route to his longest outing and first quality start of the campaign. Peterson will likely sick in the rotation for awhile given the lengthy absence Scherzer is facing, and he'll carry an excellent 2.16 ERA into his next start, which is expected to come at home against Washington next week.

Peterson was recalled from Triple-A Syracuse and will start Monday against the Giants, Tim Healey of Newsday reports.

The roster move was a formality, as the Mets announced Sunday that Peterson would take the ball to open the series in San Francisco. Peterson has split time between Syracuse and the majors early this season, and he's delivered a 1.89 ERA and 1.11 WHIP with a 16:8 K:BB across 19 innings in New York. Jake Reed was optioned to Triple-A Syracuse in the corresponding move.

Peterson confirmed that he will be called up from Triple-A Syracuse to start Monday's game in San Francisco, Deesha Thosar of the New York Daily News reports.

Peterson's appointment to the rotation was fully expected after Max Scherzer landed on the 15-day injured list Saturday with a high-grade oblique strain that is expected to sideline him for 6-to-8 weeks. The 26-year-old lefty had already joined the Mets for the road trip as a member of the taxi squad once the news of Scherzer's injury broke, but New York will wait until Monday to formally recall Peterson from Triple-A. Peterson performed well in his first four outings (three starts) with the big club earlier this season, posting a 1.89 ERA, 1.11 WHIP and 16:8 K:BB across 19 innings. Given the severity of Scherzer's injury, Peterson should have a decent amount of leash in the rotation as he rejoins the big club.

Peterson was optioned to Triple-A Syracuse on Wednesday.

Peterson started the first game of Tuesday's doubleheader against Atlanta and allowed four runs (three earned) on four hits and three walks while striking out six in five innings. He has a 1.89 ERA and 1.11 WHIP in 19 innings over four appearances (three starts) in the majors this year and will be a strong candidate to step in if the Mets need a spot starter at some point.

Peterson (1-0) picked up the win in the first game of Tuesday's doubleheader against Atlanta, giving up four runs (three earned) on four hits and three walks over five innings. He struck out six.

A three-run blast by Matt Olson in the fifth inning accounted for most of the damage off Peterson, but the Mets had already built a 5-1 lead and Atlanta couldn't find a tying run. The southpaw has pitched well enough to stay in the rotation, posting a 1.89 ERA, 1.11 WHIP and 16:8 K:BB through 19 innings in the majors this season, but it's not clear what the Mets' plans are for the 26-year-old after the twin bill.

Peterson was called up from Triple-A Syracuse and will start the first game of Tuesday's doubleheader with Atlanta.

Manager Buck Showalter previously relayed Monday that Peterson would be summoned from the minors to make a start during the doubleheader, though the skipper didn't specify whether the southpaw would get the ball in Game 1 or Game 2. Peterson will ultimately oppose Charlie Morton in the afternoon affair, while Carlos Carrasco takes the hill for the Mets in the nightcap. Before being demoted to Syracuse on April 23, Peterson made three appearances (two starts) for the Mets, working 14 innings while giving up one earned run on nine hits and five walks.

Peterson will be recalled to start one half of Tuesday's doubleheader against Atlanta, though the Mets have yet to specify which game, Tim Healey of Newsday reports.

Peterson has made two starts and one relief appearance for the Mets this season, allowing just one run on nine hits in 14 innings of work despite an unimpressive 18.9 percent strikeout rate. Trevor Williams picked up the team's most recent spot start in late April, but it looks as though Peterson will be the preferred option Tuesday.

Peterson was optioned to Triple-A Syracuse on Saturday, Mike Puma of the New York Post reports.

Peterson allowed just one run over 5.2 innings in Friday's victory over the Diamondbacks, and that was the only run he has surrendered through 14 innings this season. However, with him unavailable until sometime next week, the Mets decided to remove him from the roster and open up a spot for reliever Adonis Medina. Given how he has pitched thus far, don't expect Peterson's stay in the minors to be a long one.

Peterson didn't factor into the decision during Friday's 6-5 win over Arizona, allowing one run on three hits and a walk with three strikeouts in 5.2 innings.

Pitching for a second straight time against the Diamondbacks, Peterson fared nearly as well despite surrendering his first run of the season but was left unsatisfied when the bullpen blew a four-run lead. The 26-year-old has now allowed just one run in 14 innings this season while permitting 14 baserunners compared to 10 strikeouts. With an off day next week, manager Buck Showalter has opted to skip Peterson though that decision is made more difficult by another successful turn.

Peterson pitched 4.1 scoreless innings, allowing three hits and two walks while striking out four in a 5-0 win Sunday against Arizona. He did not factor into the decision.

Peterson did not allow a runner past second base in his first start of the season. The lefty wasn't exactly efficient, needing 80 pitches to get through 4.1 innings, but he got the job done. After not making the team out of spring training, the 26-year-old has pitched very well to start the season and has yet to allow a run in 8.1 innings. He is scheduled to start against the Diamondbacks again on Friday in Arizona.

Peterson will start Sunday against Arizona, Tim Healey of Newsday reports.

Peterson is the seventh starter on the Mets' depth chart and didn't even make the Opening Day roster, but he'll be needed already in the 10th game of the season after shoulder injuries to Jacob deGrom and Taijuan Walker. The lefty pitched four innings of scoreless relief after Walker exited his start Monday against the Phillies, so he's stretched out and on schedule for Sunday's outing. Through 24 career major-league starts and two relief appearances, Peterson owns a 4.49 ERA and 1.31 WHIP. He could get the chance to make multiple starts in place of Walker, who's expected to require a rehab outing.

Peterson threw four scoreless innings in relief of Taijuan Walker (shoulder) during Monday's 5-4 loss to the Phillies, allowing three hits and two walks while striking out three.

Walker left the game after two innings, forcing Peterson into the game with the Mets holding a 3-0 lead. The southpaw was sharp, tossing 32 of 58 pitches for strikes, and he was in line for the win until the bullpen fell apart late. If Walker is forced to miss additional time, something that should become clearer after he undergoes an MRI on Tuesday, Peterson figures to be next in line to take his spot in the rotation.

Peterson was recalled from the taxi squad Saturday, Anthony DiComo of MLB.com reports.

Peterson was the team's final cut of spring training, but he'll be needed again right away with Edwin Diaz away on bereavement leave. Peterson may just be an extra bullpen arm for a few days until Diaz returns this time around, but he has the potential to enter the rotation later in the season if more Mets starters get injured.

The Mets optioned Peterson to Triple-A Syracuse on Thursday.

Peterson was the Mets' final cut of spring training. His demotion to the minors was foreshadowed Wednesday, when manager Buck Showalter confirmed that No. 5 starter Tylor Megill would get the ball in Thursday's season opener versus the Nationals. With ace Jacob deGrom (shoulder) beginning the season on the IL, Peterson looks to be viewed as the No. 7 starter on the organizational depth chart. The 26-year-old lefty will thus likely need at least two other members of the rotation to be sidelined before he gets a look as a starter with the big club.

Peterson could begin the season in the Mets' rotation despite giving up three home runs through 6.2 Grapefruit League innings.

The southpaw's 6:2 K:BB this spring looks good, but keeping the ball in the park was a serious issue for Peterson in 2021, and it doesn't look like he's solved it yet. Still, with Jacob deGrom (shoulder) already ruled out to begin the season and Max Scherzer (hamstring) now day-to-day, Peterson could find himself in the Opening Day rotation, making him a roster option in deep mixed and NL-only formats.

Peterson revealed Tuesday via his personal Instagram account that he underwent surgery to repair a fractured bone in his right foot, Anthony DiComo of MLB.com reports.

Assuming the procedure went as anticipated, Peterson will have a chance to make it back from the 60-day injured list at some point in September, but he likely won't have enough time to build back up for a starting role. Before suffering the toe injury, Peterson made 15 starts for the Mets, posting a 2-6 record, 5.54 ERA and 1.40 WHIP.

Peterson will undergo surgery to repair his broken right pinky toe, which could potentially end his season, Anthony DiComo of MLB.com reports.

Peterson was working his way back from an oblique strain when he fractured his toe. The Mets haven't officially shut him down for the season, but the foot surgery typically requires six to eight weeks to recover from. That takes him to at least the start of September, at which point he'll still have to go through a throwing program. If he returns at all, he may do so as a reliever, given that he might not have time to build back up to a starter's workload.

Peterson was transferred to the 60-day IL due to a fractured right pinky toe, Tim Healey of Newsday reports.

The lefty landed on the 10-day IL on July 2 with an oblique strain, but now the toe fracture will demand a more extended absence. It's unclear whether Peterson's oblique Is healed and he's only out due to the toe, or if he's still dealing with both injuries. More details about his health and a possible return timeline should become available in the next couple weeks.

Peterson (oblique) was transferred to the 60-day injured list Saturday.

Peterson has been sidelined since July 2 due to an oblique strain, but he's been participating in a throwing program recently and is nearing his return to mound work. However, the southpaw will now be sidelined until early September following his shift to the 60-day IL. The move clears up a spot on the 40-man roster for Mark Payton, who was acquired from the Reds on Saturday.

Mets manager Luis Rojas said Tuesday that Peterson (oblique) could start throwing off a mound as soon as this weekend, but the lefty remains "weeks away" from returning from the 10-day injured list, Mike Puma of the New York Post reports.

Peterson resumed playing catch shortly before the All-Star break and will likely continue to stretch out his throwing distance for at least a few more days before stepping on a mound. Once that happens, he'll still likely need at least two weeks to fully ramp up for starting duty, making it difficult at this point to gauge a target date for his return. Fantasy managers shouldn't count on Peterson pitching for the Mets any earlier than mid-August.

Peterson (oblique) played catch Sunday for the first time since his injury, Tim Healey of Newsday reports.

Peterson has been sidelined since June 30 and has taken his first step towards a return to the mound. He's still expected to be sidelined for quite some time however, as he was originally projected to miss just shy of eight weeks.

Peterson was diagnosed with an oblique strain Saturday, Tim Britton of The Athletic reports.

Peterson was placed on the 10-day injured list with what was initially described as right side soreness, but he's apparently dealing with an oblique issue. Manager Luis Rojas said that the severity is between Grade 1 and Grade 2, and the injury typically carries a recovery timetable of approximately eight weeks. While the team's medical staff is optimistic that Peterson could return sooner than that, he'll likely miss extended time due to the injury.

Peterson (side) was placed on the 10-day injured list Friday.

The left-hander was pulled from Wednesday's start versus Atlanta with soreness in his right side, and the severity of the injury remains unclear. Peterson will be eligible to return July 11, the last day before the All-Star break, though it's more likely he won't return until after the midseason festivities.

Peterson (side) won't make his next start, Anthony DiComo of MLB.com reports.

Peterson was removed from Wednesday's start against Atlanta in the top of the fourth inning with right side soreness, and he's still experiencing tightness Thursday. He'll undergo further evaluations once the team returns to New York this weekend, but he'll miss at least one turn through the rotation and could require a trip to the injured list as a result. Manager Luis Rojas said that Corey Oswalt and Thomas Szapucki are candidates to start in Peterson's place, DiComo reports.

Peterson left his Wednesday start against Atlanta in the top of the fourth inning with right side soreness, Justin Toscano of The Bergen Record reports. He struck out two while being charged with six runs (five earned) on eight hits and one walk across three-plus innings.

Peterson wasn't sharp from the start of the game, allowing two runs in the first inning before allowing two more in the third. He departed with the injury after allowing a double and single to start the fourth and it was reported soon after that he was dealing with soreness in his right side. He'll be further evaluated before the Mets reveal the severity of the injury and he can be considered questionable to make his next start.

Peterson allowed a run on three hits and two walks over six innings in a loss to the Phillies in the second game of Friday's doubleheader. He struck out five and did not factor in the decision.

Peterson cruised through five innings of scoreless baseball before serving up a solo shot to Bryce Harper in the sixth. It was his third straight outing giving up fewer than two runs, lowering his season ERA to 4.95 through 63.2 innings. He'll carry a 67:28 K:BB into next week's projected start in Atlanta.

Peterson allowed one run on two hits and a walk across 4.2 innings in the win over Washington in Game 1 of Saturday's doubleheader. He struck out six and did not factor in the decision.

It wasn't the most efficient outing from Peterson, as the left-hander threw 94 pitches (54 strikes) while failing to get through the fifth inning, ultimately leaving him ineligible to pick up his third win. Nonetheless, his outing was far from disastrous, especially considering that it came in a seven-inning game in which the bullpen only needed to work 2.1 frames. Peterson currently lines up to take the ball for one of the two games of next Friday's doubleheader against the Phillies.

Peterson (2-5) picked up the win Monday, allowing one hit and two walks over six scoreless innings in a 5-2 victory over the Cubs. He struck out three.

The southpaw threw 43 of 73 pitches for strikes as he put together his fifth quality start of the season. Peterson had coughed up nine runs in only three innings over his last two outings however, and he'll need to find some consistency before he'll be anything more than a DFS dart throw. He'll carry a 5.60 ERA, 1.40 WHIP and 56:23 K:BB through 53 innings on the season into his next start.

Peterson (1-5) took the loss Tuesday at Baltimore after giving up four runs on eight hits with four strikeouts and a walk over 2.2 innings.

The left-hander delivered a scoreless opening frame but ended up requiring 69 pitches to record only eight total outs. The 25-year-old recorded only a single out in his previous start, and he's now failed to cover four frames in four of 11 starts this season. According to Anthony DiComo of MLB.com, manager Luis Rojas said Peterson will remain in the rotation for at least one more turn despite his recent struggles, and that start tentatively lines up for early next week against the Cubs.

Peterson gave up five runs on three hits and three walks in one-third of an inning Wednesday versus Arizona. He did not factor in the decision.

It was a nightmarish start for the southpaw, who wasted the Mets' four-run burst of offense in the first inning. Peterson's two shortest appearances of the season have been against Arizona -- he lasted only 1.2 innings on May 7. He now owns a 5.89 ERA, 1.40 WHIP and 49:20 K:BB through 44.1 innings this year. Peterson projects for a start versus Baltimore next week.

Peterson won't start Saturday as previously scheduled following the postponement of Friday's contest, Anthony DiComo of MLB.com reports.

Friday's starter Taijuan Walker (side) will be pushed back to start Saturday, and the Mets have yet to decide whether Jacob deGrom will start as scheduled Sunday or also be pushed back. If deGrom remains on turn, Peterson is poised to take the mound Monday at Arizona.

Peterson (1-4) took the loss Monday, giving up three runs on five hits and three walks over six innings as the Mets fell 3-2 to the Rockies. He struck out three.

Solo shots by Ryan McMahon and Elias Diaz in the second inning hurt, but it was the run Colorado pushed across in the fourth that proved decisive. Peterson did deliver his fourth quality start of the season, and he'll take a 4.91 ERA and 49:17 K:BB through 44 innings into his next outing.

Peterson allowed three runs on five hits and a walk with five strikeouts in 4.2 innings in a no-decision versus Atlanta on Wednesday. He also hit a batter.

Peterson cruised through four innings, but ran into trouble in the fifth, where he allowed four of his hits and the hit-by-pitch. That led to three runs for Atlanta, but the Mets' offense got their starter off the hook in the seventh. Peterson has a 4.97 ERA, 1.26 WHIP and 46:14 K:BB across 38 innings this season. The southpaw lines up to face Colorado next week.

Peterson allowed two runs on four hits and two walks with nine strikeouts in 7.1 innings Friday versus Tampa Bay. He did not factor in the decision.

Peterson was strong over seven innings, but he ran out of steam in the eighth. He allowed a solo home run to Mike Zunino, then let Kevin Padlo aboard with a double. Reliever Trevor May allowed the inherited runner to score, denying Peterson a decision. The 25-year-old lowered his ERA to 4.86 after his longest start of the year. He's added a 1.26 WHIP and 41:13 K:BB in 33.1 innings. Peterson lines up to face Atlanta next week.

Peterson didn't factor into the decision in Friday's 5-4 extra-inning win over the Diamondbacks, giving up three runs on three hits and three walks over 1.2 innings while striking out three.

After a scoreless first inning, the southpaw's control deserted him in the second as the final four batters he faced all reached base via a walk or a hit by pitch. Peterson has issued multiple free passes in four straight starts and five of six this season, and he'll carry a 5.54 ERA and 32:11 K:BB through 26 innings into his next outing.

Peterson allowed one earned run on four hits and two walks while striking out eight across five innings in the win over the Phillies on Sunday. He did not factor in the decision.

Peterson's only run allowed was a leadoff solo home run by Andrew McCutchen to start the game. After that, Peterson settled in to record more strikeouts (8) than hits (3) and walks (2) combined. Despite having three starts allowing two or less runs, he only has one win this season. The 25-year-old has a 4.81 ERA and has surrendered a team-high five home runs in 24.1 innings.

Peterson (1-3) took the loss Tuesday, giving up two runs on four hits and two walks over six innings as the Mets fell 2-1 to the Red Sox. He struck out three.

The left-hander was solid in his second quality start of the season, tossing 60 of 92 pitches for strikes, but he got the Jacob deGrom treatment from the Mets' offense. Homers have been an issue in the early going for Peterson as he's served up four in only 19.1 innings, fueling a 5.59 ERA and undermining a strong 21:7 K:BB. He'll look for a better result in his next outing Sunday in Philadelphia.

Peterson (1-2) allowed six runs (three earned) on four hits and two walks while striking out three over 3.1 innings as he took the loss against the Cubs on Wednesday.

Peterson started out fantastic after retiring the first 10 batters he saw in order but completely fell apart thereafter. The 25-year-old let up his first hit of the game on an infield single by Willson Contreras with one out in the fourth and just could not get out of his own way afterward. He eventually loaded the bases only to end up walking in a run to tie the game up at two and then was punished by David Bote on a two-run single to shallow right to put the Cubs up 4-2. He exited the ballgame and was hit with two more runs to his final line after Robert Gsellman was unable to keep the inherited runners from scoring after relieving Peterson. It's been an up-and-down start to the year for the left-hander. He's had one very good start sandwiched between a pair of bad ones as his ERA now sits at a 6.75 heading into his next start against the Red Sox on Tuesday.

Peterson (1-1) picked up the win Wednesday in a 5-1 victory over the Phillies, giving up one run on two hits over six innings while striking out 10.

The young southpaw was in firm control, tying his career high in strikeouts, and he made only one real mistake that Jean Segura launched over the fence in the fifth inning. Peterson threw 57 of 80 pitches for strikes in his first quality start of the year, but after a rough season debut he'll still carry a 6.30 ERA into his next outing, set for April 21 on the road against the Cubs.

Peterson won't start against the Phillies on Monday since the game was postponed due to inclement weather, Anthony DiComo of MLB.com reports.

Although Peterson won't be able to make his second start of the season Monday, he could be in line to take the mound for one of the games in Tuesday's doubleheader. The southpaw took the loss in his season debut against Philadelphia on Wednesday, allowing six runs on seven hits and two walks while striking out five in four-plus innings.

Peterson (0-1) took the loss Wednesday as the Mets fell 8-2 to the Phillies, coughing up six runs on seven hits and two walks over four-plus innings. He struck out five.

The southpaw got his 2021 off to a shaky start as he served up first-inning homers to Rhys Hoskins and Alex Bohm, but Peterson regained his focus and blanked the Phillies over the next three frames before running out of steam in the fifth. He threw 54 of 78 pitches for strikes, but with five of the seven hits off him going for extra bases, Peterson's issue was command within the zone and not simply getting the ball over the plate. He'll get a chance for revenge against the Phillies in his next scheduled outing at home Monday.

Peterson is scheduled to start Sunday in the finale of the Mets' season-opening series with the Nationals, Anthony DiComo of MLB.com reports.

Peterson looked as though he would have to battle Joey Lucchesi for the fifth starter's role early in camp, but spots opened up for both pitchers after Carlos Carrasco suffered a hamstring tear that will sideline him into May. The lefty will now have at least the first month of the season to solidify a permanent spot in the rotation. The 3.44 ERA and 1.21 WHIP he submitted over his 10 outings as a rookie last season were strong on the surface, but most underlying numbers (7.8 K-BB%, 5.11 xFIP) painted a less rosy picture of his performance. He'll likely need to miss more bats or hope for continued good luck on balls in play in order to deliver another sub-4.00 ERA season in 2021.

Peterson is very likely to break camp in the rotation, Tim Britton of The Athletic reports.

Peterson always seemed likely to open the year in the rotation, as he spent most of last season there and acquitted himself well, though his 19.5 percent strikeout rate and 11.7 percent walk rate didn't come close to backing up his 3.44 ERA. Carlos Carrasco's hamstring issue means there are now two spots available for some combination of Peterson, Joey Lucchesi and Jordan Yamamoto, however, and it would be a surprise if Peterson was the odd man out among that group. Lucchesi and Yamamoto combined to throw 17 major-league innings last year, giving up 28 earned runs.

Peterson allowed one hit and hit a batter across two scoreless innings Thursday against the Nationals.

Peterson threw 26 pitches in his spring debut and was largely sharp. He labored a bit in the first frame -- he hit a batter and then allowed a double with two outs -- but got out of the jam. Peterson then rebounded in the third inning to retire the side in order. Though the favorite to begin the season as the fifth starter, Peterson will have to beat out Joey Lucchesi, Sean Reid-Foley and Jordan Yamamoto for the role.

Peterson may not begin the season in the rotation due to workload concerns and the Mets' offseason additions, Anthony DiComo of MLB.com reports.

Peterson was excellent in the 2020 campaign, pitching primarily as a starter and posting a 3.44 ERA, 1.21 WHIP and a 40:24 K:BB across 49.2 innings. However, his relatively low workload could convince the Mets to start him in the bullpen or minor leagues. While his workload will be monitored regardless of his role with the club, Peterson will have the chance to compete with Joey Lucchesi, Jordan Yamamoto, Jerad Eickhoff and Sean Reid-Foley for a spot in the rotation.

Peterson (6-2) allowed one run on four hits and one walk while striking out four over seven innings in a win over the Nationals on Thursday.

His strikeout total fell back down after his 10-K gem against Atlanta last weekend, but Peterson was effective even without a lot of swing-and-miss, and he can hold his head high heading into the offseason after posting a 2.00 ERA in his final three outings. The lefty has been a bright spot for the Mets this season and should have the inside track on a rotation spot heading into spring training. Overall, Peterson turned in a 3.44 ERA, 1.21 WHIP and 40:24 K:BB in 49.2 innings.

Peterson (5-2) struck out a career-high 10 batters to pick up the win in Saturday's 7-2 victory over Atlanta, allowing one run on three hits and four walks over six innings.

The 25-year-old rookie hadn't fanned more than three batters in any of his previous six appearances, but Peterson took full advantage of Atlanta's over-eager bats Saturday. The southpaw will take a 3.80 ERA, 1,29 WHIP and 36:23 K:BB through 42.2 innings into his final start of the regular season Thursday, on the road against the Nationals.

Peterson will start Saturday's game against the Braves, Tim Healey of Newsday reports.

The 25-year-old previously lined up to start Friday's series opener, but the Mets wanted to provided him an extra rest day. Peterson has a 4.17 ERA, 1.31 WHIP and 26:19 K:BB through 36.2 innings this season. Steven Matz is set to start Friday's contest.

Peterson (4-2) took the loss Sunday against Toronto, allowing two runs on three hits and two walks across five innings. He struck out two.

Peterson was coming off a rough outing against the Phillies in which he allowed five runs over just two innings. Though he took the loss Sunday, it was a much better showing for the left-hander. He allowed a two-run homer to Lourdes Gurriel in the second, but managed to keep the Jays off the board over the next three innings. Peterson will take a 4.17 ERA and a 4-2 record into his start against the Braves on Friday.

Peterson will start Sunday's game against the Blue Jays in Buffalo.

After a one-game cameo in the bullpen, Peterson moved back into the rotation Sept. 7 and was lit up by the Phillies, giving up five runs on three hits and four walks in two innings. The Mets don't have many other appealing starting options to turn to, so Peterson will be given the opportunity to try and bounce back against the Blue Jays.

Peterson allowed five earned runs on three hits and four walks while striking out three across two innings Monday against the Phillies. He did not factor into the decision.

Peterson battled his control in the short outing, hitting and walking a batter in the first inning -- which led to three earned runs. The next frame, he walked the second batter he faced prior to serving a two-run homer to Rhys Hoskins. It was a disastrous start for Peterson, after he briefly was shifted to a bullpen role. He'll look to bounce back in his next outing, currently projected to come Sunday at Toronto.

Peterson will return to the rotation to start Monday against the Phillies, Anthony DiComo of MLB.com reports.

Peterson moved to the bullpen earlier in the weekend, though arrangement was evidently a very temporary one, as he'll return to the rotation after pitching just once in relief. Peterson has been quite a useful arm for the Mets in 29.2 innings this season, posting a 3.03 ERA, though his 17.4 percent strikeout rate and 10.7 percent walk rate don't seem to bode well for his future.

Peterson (4-1) earned the win Wednesday in Baltimore after allowing two hits with one strikeout and two walks over four scoreless innings.

The 25-year-old made one start after returning from the injured list last week before getting shifted to the bullpen, but he ended up grabbing the win in his first outing as a reliever. Peterson has a 3.03 ERA and 1.21 WHIP over 29.2 innings this season, though his 21:13 K:BB leaves something to be desired. He'll be unavailable for the next few days after throwing 59 pitches.

Peterson will be available out of the bullpen Wednesday and is not scheduled to start either of the Mets' next two games, Tim Healey of Newsday reports.

Peterson owns a strong 3.51 ERA through the first five starts of his big-league career, though his 18.9 percent strikeout rate and 10.4 percent walk rate are both fairly poor. He wasn't great in his first start back from shoulder inflammation Friday, allowing three runs in four innings against the Yankees. It's possible the rookie moves back into the rotation at some point in the near future, pushing either Robert Gsellman or Seth Lugo, who began the year in the pen, back to their original roles, but it will be Gsellman, rather than Peterson, who starts against the Yankees on Thursday.

Peterson allowed three runs on four hits and three walks while striking out three over four innings in Friday's Game 2 win against the Yankees. He didn't factor into the decision.

Peterson was relatively effective in his first start since dealing with shoulder inflammation, but he allowed a rally in the third inning. As a result, he had to settle for the no-decision. The southpaw now carries a 3.51 ERA over 25.2 innings in his first five starts this season and should be available going forward. His next start should come at home Thursday against the Yankees.

Peterson (shoulder) was activated from the 10-day injured list ahead of Friday's start against the Yankees, Anthony DiComo of MLB.com reports.

Peterson was sidelined for 15 days while dealing with left shoulder inflammation, but he'll start the second game of Friday's twin bill. It's unclear whether he'll have any workload restrictions Friday, but he should be available in the starting rotation going forward.

Peterson (shoulder) will start Game 2 of Friday's doubleheader against the Yankees, Anthony DiComo of MLB.com reports.

He will need to be officially activated from the injured list following Game 1. Peterson has been sidelined for 15 days with left shoulder inflammation, and it is unclear if he will be able to handle a normal workload in the nightcap.

Peterson (shoulder) threw another bullpen session Wednesday, Anthony DiComo of MLB.com reports.

Wednesday's throwing session marks Peterson's second bullpen in three days. The right-hander has been sidelined since Aug. 16 with a shoulder issue, but manager Luis Rojas noted he's a candidate to rejoin the rotation in the near future.

The Mets are hopeful that Peterson (shoulder) can return to the rotation this week, Tim Healey of Newsday reports.

The Mets have three doubleheaders plus three additional games on tap over a six-day span starting Tuesday, so they could really use Peterson if he is healthy enough to return. He was placed on the injured list last week with shoulder fatigue and an MRI showed no structural damage. Peterson, who last pitched Aug. 13, would be eligible to return for this upcoming series against the Marlins, but it's unclear if that is realistic.

Peterson's MRI on his sore left shoulder Wednesday revealed minor inflammation but no structural damage, Justin Toscano of The Bergen Record reports.

The lack of structural damage is undoubtedly good news for Peterson and the Mets, though he'll still miss at least one more start while he remains on the injured list. It's not yet clear when the Mets expect him to return, as his timeline will likely depend on how quickly the inflammation subsides.

Peterson underwent an MRI on his sore left shoulder Wednesday, Tim Healey of Newsday reports.

Peterson was scratched from his scheduled start Tuesday against the Marlins and will miss at least one more turn in the rotation, as he's since been placed on the injured list. A clearer sense of his timeline should emerge once the results of the MRI are known.

Peterson was scratched from his scheduled start Tuesday and placed on the 10-day injured list with left shoulder fatigue, Tim Healey of Newsday reports.

Peterson had put together a nice start to the season over his first four starts and had secured two consecutive wins. However, he'll now miss at least two turns through the rotation as a result of a shoulder issue. The exact severity of the injury is unclear, but Corey Oswalt will start in Peterson's place Tuesday.

Peterson (shoulder) is ready to make his scheduled start Tuesday against the Marlins, Tim Healey of Newsday reports.

Peterson's last start was cut short due to shoulder soreness, but he didn't sound too concerned about the issue. The southpaw threw a side session Sunday and apparently felt healthy enough afterward to make his scheduled start Tuesday. As long as he remains healthy, he should be locked into a rotation spot going forward.

Peterson (shoulder) will throw a side session Sunday and if all goes well, he will make his scheduled start Tuesday in Miami, David Lennon of Newsday reports.

He only threw 74 pitches in his last start after experiencing some shoulder soreness but said after the outing that it was nothing to worry about. The Mets' rotation depth has been tested early and often, so Peterson's spot in the rotation is locked in as long as he is healthy.

Peterson (3-1) picked up the win in Thursday's 8-2 victory over the Nationals, allowing one unearned run on one hit and two walks over five innings. He struck out three.

Peterson continued his steady start to his league career Thursday. The right-hander has logged at least five innings and allowed three or less runs in each of his four starts. The rookie will carry a strong 2.91 ERA into his next start, which is scheduled to come next week against the Marlins.

Peterson (2-1) allowed two runs on four hits and three walks while striking out three over five innings in a win over the Marlins on Saturday.

This was not the most dominant performance, but Peterson did enough to earn his second MLB win and hand the Marlins just their second loss of the season. The 24-year-old lefty entered Saturday's game with a 17.0 K-BB% through his first two starts, so he's been a bright spot at the back end of the Mets' rotation. Peterson lines up for another home start next week against the Nationals.

Peterson (1-1) allowed three runs on five hits and one walk while striking out eight over six innings as he was charged with the loss Sunday against the Braves.

Peterson was relatively effective in his second MLB start, but the Mets were unable to generate any offensive production, resulting in a loss for the southpaw. Despite Sunday's decision, Peterson has held his own over his first taste of major-league action, posting a 3.86 ERA and 11:3 K:BB over 11.2 innings to begin the year. His next start should come at home Saturday against the Marlins.

Peterson (1-0) picked up the win in Tuesday's 8-3 victory over the Red Sox, allowing two runs on seven hits and two walks over 5.2 innings. He struck out three.

The 24-year-old southpaw looked like a veteran on the mound in his big-league debut, working out of trouble in the third inning by fanning J.D. Martinez and mostly cruising from there. Peterson figures to hold down a rotation spot at least until Marcus Stroman (calf) gets healthy, but if he continues to perform at a reasonably high level he could stick around beyond that.

The Mets officially selected Peterson's contract from their alternate training site Tuesday in advance of his scheduled start against the Red Sox.

New York designated Ty Bashlor for assignment to clear spots on the 40-man roster and 30-man active roster for the 24-year-old southpaw. Peterson whiffed 24.5 percent of the batters he faced at the Double-A level in 2019 and excelled at generating groundballs, but the latter attribute could contribute to an inflated WHIP in the majors, especially with a shaky Mets defense behind him.

Peterson will be called up to start against the Red Sox on Tuesday for his major-league debut, Tim Healey of Newsday reports.

Peterson is at least a moderately interesting prospect, with a back-end starter profile driven by command and groundballs. He did manage to strike out a solid 24.5 percent of opposing batters in 24 Double-A starts last season, though he sits around 90 mph with his fastball and may not strike out too many hitters at the big-league level. He was hardly dominant at Double-A Binghamton last year, either, posting a modest 4.19 ERA, so expectations shouldn't be too high as he makes the jump to the majors for his first career start.

Peterson could be added to the 30-man roster in order to make a spot start or serve as a bulk reliever Tuesday, Tim Britton of The Athletic reports.

The Mets' pitching depth is already being tested, as Rick Porcello's short outing Sunday forced Corey Oswalt to throw over 70 pitches in relief and took him out of the picture for Tuesday's start. Peterson and Erasmo Ramirez -- or perhaps even both of them -- are the most likely candidates to get the call to soak up some innings, but as neither of them are currently on the 40-man roster, the club could also elect to try and piece together a pure bullpen game instead.

Peterson tossed 2.1 scoreless innings during Wednesday's intrasquad scrimmage, Anthony DiComo of MLB.com reports.

The young southpaw struck out Michael Conforto and Brandon Nimmo during the outing. With Jacob deGrom (back) now iffy for Opening Day, Peterson could begin the season in the Mets rotation. "I'm ready when that call comes in," Peterson said after the scrimmage.
