ANALYSIS
Williamson cruised to an easy win with 14 runs of support before he left the contest. It was his longest outing since Aug. 29 and first win since Aug. 7.

Sep 24, 2023
Pulled in the fifth
Williamson did not factor into the decision Sunday, allowing two runs on four hits and one walk over 4.1 innings against Pittsburgh. He struck out three.
ANALYSIS
Williamson allowed only two baserunners through four but was tagged by a Jack Suwinski solo homer to lead off the fifth. Williamson then allowed a one-out double to Henry Davis followed by an RBI single by Jason Delay and was removed after 74 pitches. Following a stretch where he worked into the sixth in eight of nine starts, Williamson has failed to get through the fifth in each of his last three appearances. The rookie has started 22 games for the Reds spanning 111 innings and will carry a 4.54 ERA into his final start of the regular season, scheduled to take place next weekend in St. Louis against the Cardinals.
Sep 17, 2023
Loses to Mets
Williamson (4-5) yielded three runs on six hits and a walk over four innings Sunday, striking out two and taking a loss against the Mets.
ANALYSIS
Williamson began the game with a pair of scoreless frames before coughing up three runs in the third.

Sep 12, 2023
Struggles in return
Williamson did not factor into the decision Tuesday, allowing five runs on seven hits and two walks over four innings against the Tigers. He struck out four.
ANALYSIS
Williamson returned from the COVID-19-related injured list Tuesday and only lasted four innings, his shortest outing since July 6. The 25-year-old rookie looked especially rusty during a 29-pitch first inning in which he allowed three runs on five hits. Williamson looks to bounce back in his next start, scheduled to be at the Mets.
Sep 12, 2023
Activated for Tuesday's start
Williamson (illness) was activated from the COVID-19-related injured list ahead of his scheduled start Tuesday at Detroit.
ANALYSIS
Williamson wound up missing a couple of weeks while battling COVID-like symptoms. The 25-year-old left-hander returns to a 4-4 record, 4.20 ERA, 1.24 WHIP and 87:33 K:BB through his first 19 major-league starts covering 98.2 innings.
Sep 11, 2023
Slated to return Tuesday
Williamson (COVID-19) will start for the Reds on Tuesday against the Tigers, Gordon Wittenmyer of The Cincinnati Enquirer reports.
ANALYSIS
Williamson will have gone exactly two weeks between starts, as he's been sidelined while on the COVID-19 injured list. The left-hander had turned in back-to-back quality starts before going on the IL, but he's been up-and-down this season and might not be ready for a full workload Tuesday.
Sep 2, 2023
Won't start Sunday
Williamson was placed on the COVID-19 injured list and won't start as scheduled Sunday against the Cubs, Charlie Goldsmith of The Cincinnati Enquirer reports.
ANALYSIS
Williamson joins Hunter Greene, Ben Lively and Fernando Cruz as Reds pitchers on the COVID list. No replacement starter has been named for Sunday, but Connor Phillips, Michael Mariot and Levi Stoudt are among options to be called up from Triple-A Louisville.
Aug 30, 2023
Gets no help in loss
Williamson (4-4) allowed five runs (three earned) on six hits and struck out five without walking a batter over six innings, taking the loss Tuesday versus the Giants.
ANALYSIS
Williamson was let down by his offense and defense. An error in the third inning ultimately led to Patrick Bailey's two-run home run, while the Cincinnati bats were held without a hit until the ninth inning. Williamson finishes August with mixed results, allowing four or more runs in three of his six starts without giving up more than one run in any of the other three outings. He's at a 4.20 ERA, 1.24 WHIP and 87:33 K:BB through 98.2 innings across 19 starts overall. The rookie southpaw is lined up for a home start versus the Cubs over the weekend.
Aug 25, 2023
Tosses six scoreless frames
Williamson ended with a no-decision against Arizona on Thursday, allowing six hits and one walk while striking out six batters over six scoreless innings.
ANALYSIS
All six of the hits against Williamson were singles, and he picked up his fifth quality start of the campaign. The southpaw struck out exactly six batters for the third straight game, and he's pitched well over that stretch despite not picking up any wins, posting a 2.60 ERA, 1.21 WHIP and 18:4 K:BB over 17.1 innings. Williamson has had a few blow-ups this season but has been mostly consistent, giving up three or fewer earned runs in 14 of his 18 outings. He's at a 4.18 ERA, 1.25 WHIP and 82:33 K:BB over 92.2 frames overall.
Aug 20, 2023
Allows four runs in loss
Williamson (4-3) took the loss Saturday, allowing four runs on nine hits and one walk over 5.2 innings against Toronto. He struck out six.
ANALYSIS
Williamson allowed nine hits to Toronto, eight of which were singles, including a string of three consecutive run-scoring base knocks in the fourth inning. The one extra-base hit surrendered by the 25-year-old was a fifth-inning solo homer by Davis Schneider, which gave the Blue Jays a 4-3 lead and proved to be the difference. After a challenging start to his rookie campaign, Williamson has pitched well since the start of July, posting a 3.38 ERA, 1.08 WHIP and 47:15 K:BB across 48 innings during that stretch. He currently lines up to face Arizona on the road next week.
Aug 14, 2023
Allows one run
Williamson yielded one run on two hits and two walks over 5.2 innings in Game 1 of Sunday's doubleheader against the Pirates. He struck out six and did not factor in the decision.
ANALYSIS
Williamson allowed a leadoff single to Ke'Bryan Hayes before retiring 12 straight batters. The Pirates then broke through with a run in the fifth inning. Williamson has given up just two runs while registering a 15:2 K:BB over his last two outings. His season ERA dropped to 4.33 with a 70:31 K:BB through 81 innings. Williamson's next outing is projected to be at home against the Blue Jays.
Aug 12, 2023
Start postponed
Williamson's scheduled start Saturday against the Pirates was postponed due to inclement weather.
ANALYSIS
The Pirates and Reds will play a doubleheader Sunday to make up for Saturday's postponed contest, and Williamson will presumably start in one of the two games. The 25-year-old southpaw holds a 4.32 ERA and 1.26 WHIP across his last three starts.
Aug 7, 2023
Punches out nine
Williamson (4-2) allowed one run on three hits over 6.2 innings Monday, striking out nine and earning a win over Miami.
ANALYSIS
After coughing up a solo shot to Jorge Soler in the first inning, Williamson locked in and dominated the Marlins. Williamson struck out a career-high nine batters while tying his longest MLB outing. He had a slight hiccup against the Cubs in his last start following a dominant July; The 25-year-old posted a 2.45 ERA in five starts last month but yielded five runs in his most recent appearance. Williamson will carry a 4.54 ERA into his next outing, which is projected to be in Pittsburgh.
Aug 3, 2023
Can't get out of fifth inning
Williamson allowed five runs on four hits and two walks while striking out seven batters in a no-decision against the Cubs on Wednesday.
ANALYSIS
Williamson got enough early run support to hold a 5-3 lead through four innings, but he allowed two of the first three batters he faced to reach base in the fifth before getting the hook. Both runners came around to score after his departure, marking the first time Williamson has allowed five runs in an outing since he yielded six to the Dodgers on June 7. The southpaw as least managed to contribute seven punchouts in the start Wednesday despite notching just four swings-and-misses. Williamson came out of the All-Star break by picking up two wins and posting a 2.55 ERA over his first three starts, but it's uncertain if he'll hold onto a rotation spot when Hunter Greene (hip) and Nick Lodolo (lower leg) return from the injured list, which is expected to happen later this month. Williamson should have at least a few more starts to prove himself before the Reds need to make that decision.
Jul 29, 2023
Escapes with win
Williamson (3-2) allowed two runs on eight hits and four walks while striking out two over 5.2 innings to pick up the win Friday over the Dodgers.
ANALYSIS
Williamson's 12 baserunners were by far his most in an appearance this season, but he was able to work around the trouble. He finishes July having not allowed more than two runs in any outing, and he gave up just seven runs over 25.2 innings across his five starts for the month. Williamson has a 4.48 ERA, 1.34 WHIP and 48:27 K:BB through 64.1 innings through 13 starts this year. He's projected for a road start versus the Cubs next week.
Jul 22, 2023
Posts another quality start
Williamson (2-2) earned the win Saturday, allowing one run on three hits and one walk over six innings against the Diamondbacks. He struck out five.
ANALYSIS
Williamson got off to a red-hot start Saturday, retiring the first nine batters he faced while not allowing a single hit until the fifth inning. Though the southpaw had only logged one quality start through his first 10 appearances, he's rattled of back-to-back quality starts to lower his season ERA to 4.60 to go along with a 46:23 K:BB. However, he'll likely have a tough time nabbing a third straight quality start considering his next outing is tentatively scheduled to come against the Dodgers at Dodger Stadium.
Jul 19, 2023
No decision in series opener
Williamson allowed two runs on four hits and three walks while striking out three over six innings in Monday's 4-2 loss to the Giants.
ANALYSIS
The game was delayed by rains that wouldn't stop on Monday, so the two teams finished it off before Tuesday's regularly scheduled affair. It was the third time in Williamson's last four starts that rain impacted the game. The left-hander gave up another two home runs, increasing his count allowed to 10 over 52.2 innings (1.7 HR/9). His next outing is scheduled for Saturday against Arizona.
Jul 7, 2023
Hurls three shutout innings
Williamson did not factor into the decision Thursday, allowing one hit and one walk over three scoreless innings in a 5-4 win over the Nationals. He struck out four.
ANALYSIS
Williamson made it through just one inning before the game was delayed nearly two hours due to rain. However, despite the long break, the right-hander still returned to the mound to complete another two innings of work and actually struck out the first two batters he faced following the delay. Williamson has now allowed three earned runs or fewer in five consecutive starts and has not surrendered a home run in either of his last three.
Jul 2, 2023
Holds Padres to two runs
Williamson (1-2) took the loss Saturday, allowing two runs on three hits and one walk over five innings against the Padres. He struck out five.
ANALYSIS
Williamson actually pitched fairly well against a lethal Padres lineup, retiring eight of the first 10 batters he faced on the afternoon before surrendering an RBI double to Fernando Tatis in the top of the third. The right-hander was relieved by Buck Farmer in the sixth inning after giving up a leadoff single to Austin Nola, who would eventually come around to score on a three-run blast from Juan Soto. Williamson had allowed at least three runs in each of his last four starts coming in, so Saturday's effort, despite the loss, was still an encouraging sign for the 25 year old.
Jun 27, 2023
Struggles versus Baltimore
Williamson (1-1) took the loss Monday, allowing three runs on two hits and four walks over two innings in a 10-3 loss to Baltimore. He struck out two.
ANALYSIS
Williamson came back out for the third inning after a long rain delay, but he couldn't find a rhythm and was quickly replaced, marking the shortest outing of his career. Before Tuesday's contest, the rookie had less than ideal results through his first seven big-league starts, posting 5.40 ERA, 1.39 WHIP and 27:13 K:BB across 36.2 innings, and his poor outing versus Baltimore certainly didn't help his cause. Nonetheless, Cincinnati is dealing with numerous injuries to its starting rotation, including ace Hunter Greene (hip), so despite his struggles, Williamson role is fairly secure moving forward.
Jun 19, 2023
Fans five in no-decision
Williamson allowed three runs on six hits over five-plus innings in Monday's win over Colorado. He struck out five and did not factor in the decision.
ANALYSIS
Williamson allowed just one run through five frames before being charged with two more in the sixth inning despite not recording an out in the frame. His 5.40 remained unchanged while he improved his season K:BB to 27:13 through 36.2 innings. He's turned in two straight starts without issuing a walk but he's been tagged with six homers over his last four outings. Williamson is currently lined up for a home matchup with Atlanta this weekend.
Jun 18, 2023
Pitching Monday, may not start
Manager David Bell said Williamson is scheduled to pitch Monday against the Rockies but might not start the contest, Mark Sheldon of MLB.com reports.
ANALYSIS
The 25-year-old has a 5.40 ERA, 1.42 WHIP and 22:13 K:BB across 31.2 frames in six starts this year, and Bell is now considering using the left-hander behind an opener. Williamson could still carry some streaming appeal if working in a bulk role, though he's hardly a reliable option.
Jun 13, 2023
Records first big-league win
Williamson (1-0) earned the win Tuesday, allowing four runs on seven hits over five innings in a 5-4 victory over the Royals. He struck out one.
ANALYSIS
After not factoring into the decision in his first five starts, Williamson was finally able to secure his first victory Tuesday. The young southpaw gave up runs in each of his first three innings before settling down the rest of the way. Williamson was able to induce just seven swinging strikes on the evening, although he did throw 51 of his 78 pitches for strikes. He is scheduled to start during a three-game set against the Rockies next week.
Jun 8, 2023
Serves up three long balls
Williamson allowed six runs on eight hits and two walks while striking out three batters over 5.2 innings in a no-decision against the Dodgers on Wednesday.
ANALYSIS
Williamson looked to be in for an early hook after giving up six runs over the first three innings, but he managed to retire 10 of the final 11 batters he faced and completed 5.2 frames. The southpaw was tagged for six extra-base hits, three of which left the park. Williamson had given up three long balls across his first four outings combined, but he had struggled on that front at the Triple-A level prior to being called up in mid-May, surrendering seven homers over 34 frames. Though Williamson has looked good at times during his rookie campaign, his overall 5.40 ERA, 1.43 WHIP and 21:13 K:BB make him an unexciting fantasy option in redraft leagues.
Jun 3, 2023
Posts first quality start of career
Williamson did not factor into the decision Friday, allowing three runs on five hits and two walks over 6.2 innings in a 5-4 loss against the Brewers. He struck out six.
ANALYSIS
Williamson notched his first career quality start and tied his season high with six strikeouts. The left-hander was called up in mid-May and has been a hit-or-miss player through his first four starts at the big-league level. He allowed eight runs (seven earned) while recording more walks (seven) than strikeouts (six) over his past two starts, but he was sharp versus Milwaukee and held the Rockies to just one run over 5.2 innings at Coors Field in his MLB debut. Williamson's next start is scheduled during a three-game set versus the Dodgers, and barring an injury, he figures to remain in the rotation until Nick Lodolo (lower leg) is activated off the injured list.
May 28, 2023
Struggles again
Williamson allowed four runs on six hits and three walks while striking out three over 4.1 innings in a no-decision versus the Cubs on Saturday.
ANALYSIS
This was pretty similar to Williamson's last outing, though this was the first time in three starts he's avoided giving up a home run. He threw 52 of 81 pitches for strikes Saturday, but he's now logged a 12:9 K:BB over his first 14.1 major-league innings. Getting the walk rate under control would go a long way to solidifying his place on the Reds' roster. He's added a 5.02 ERA and 1.47 WHIP so far, numbers he'll look to improve upon in a tough tentative home start versus the Brewers next week.
May 23, 2023
Serves up four runs in no-decision
Williamson did not factor into the decision Monday, allowing four runs on four hits and four walks over 4.1 innings during a 6-5 win over St. Louis in 10 innings. He struck out three.
ANALYSIS
Williamson was spotted an early 2-0 lead, but that was squandered after he allowed a go-ahead three-run homer to Paul DeJong. The Reds answered back with a two-run blast of their own, and that score held until Williamson surrendered a game-tying RBI double to Lars Nootbaar in the fifth. The young pitcher didn't look as sharp as he did during his MLB debut last week, but he figures to remain in the rotation for awhile, as Nick Lodolo is expected to miss extended time while dealing with a stress reaction in his left tibia.
May 19, 2023
To make next start Monday
Williamson will make his second major-league start Monday at home against the Cardinals, Charlie Goldsmith of The Cincinnati Enquirer reports.
ANALYSIS
Williamson looked sharp in his debut for the Reds this past Tuesday versus the Rockies, tallying six strikeouts over 5.2 innings of one-run ball. St. Louis has picked it up offensively, but the 25-year-old left-hander might be worth of fantasy streaming consideration given Tuesday's results and his prospect pedigree.
May 17, 2023
Strong in MLB Debut
Williamson did not factor into the decision Tuesday, allowing one run on two hits and two walks over 5.2 innings against Colorado. He struck out six.
ANALYSIS
Despite getting a tough draw for his MLB debut coming at hitter-friendly Coors Field, Williamson came through for those who were willing to take a shot on the rookie, delivering six strikeouts over 5.2 innings while allowing just two hits. After posting a poor 6.62 ERA across 34 Triple-A innings this season, managers shouldn't go all-in on the southpaw based on Tuesday's outing. Though Williamson could carry some streaming appeal moving forward, he's currently expected to take the mound this weekend during a three-game homestand against the Yankees, who have hit the fourth most home runs and scored the 10th most runs in MLB this year.
May 16, 2023
Promoted for MLB debut
The Reds recalled Williamson from Triple-A Louisville on Tuesday.
ANALYSIS
As anticipated, Williamson will make his MLB debut in a start Tuesday night against the Rockies. The game is at Coors Field and Williamson had struggled to a 6.62 ERA and 1.88 WHIP through 34 innings this season at Triple-A, so he's probably more of a wait-and-see type in fantasy. The 25-year-old left-hander could carry streaming appeal in more favorable matchups down the line.
May 15, 2023
Confirmed as Tuesday's starter
Williamson will start Tuesday's game against the Rockies, Charlie Goldsmith of The Cincinnati Enquirer reports.
ANALYSIS
The Reds confirmed Monday night that Williamson will make his MLB debut in a traditional start at Coors Field. This will likely be a challenging environment for his first big-league action, especially considering he's failed to look very sharp in the minors so far this year. Williamson has posted a 6.62 ERA and 1.88 WHIP with a 27:20 K:BB across 34 frames (eight starts).
May 15, 2023
Set for MLB debut Tuesday
Williamson will make his major-league debut Tuesday in Colorado, Bobby Nightengale of the Cincinnati Enquirer reports.
ANALYSIS
It hasn't been determined yet whether Williamson will make a traditional start or pitch after an opener, but either way he's slated to handle the bulk of the workload for Cincinnati on Tuesday. Williamson's numbers at Triple-A Louisville have been poor, although he has pitched better lately. He's a nice prospect but isn't a recommended fantasy option in Colorado.
May 15, 2023
Likely to join rotation
Williamson has been added to the Reds' taxi squad.
ANALYSIS
The Reds currently don't have a starter listed for Tuesday's game in Colorado and it looks like that spot could go to Williamson in what would be his major-league debut. The left-hander holds an ugly 6.62 ERA and 27:20 K:BB over 34 innings at Louisville this season, although he pitched well his last two times out in yielding four runs with 11 strikeouts across 11.2 frames. Williamson was a key piece acquired from the Mariners in the Eugenio Suarez/Jesse Winker trade.
Mar 24, 2023
Reassigned to minor-league camp
Williamson was reassigned to minor-league camp by the Reds on Friday.
ANALYSIS
Williamson pitched well early on this spring as he gunned for a spot in the Reds' rotation, but he struggled lately to punch his ticket to Triple-A Louisville. The left-hander still figures to make a decent number of starts with the big club this season.
Mar 24, 2023
Smoked in final Cactus League start
Williamson gave up nine earned runs on eight hits and three walks against the Mariners on Thursday in his final spring training start.
ANALYSIS
Williamson made some good impressions early on in spring training, but he hasn't looked ready for prime time in his recent outings and is coming off of a tough year in Triple-A in 2022. It wouldn't be a shock if he was ticketed for Louisville again to begin 2023.
Feb 21, 2023
To start Cactus League opener
Williamson will start the Reds' Cactus League opener Saturday, C. Trent Rosecrans of The Athletic reports.
ANALYSIS
Williamson seems doubtful to crack the Opening Day roster in Cincinnati, but he is on track to make his MLB debut at some point in 2023. The 24-year-old struggled with command issues last season while working to a 4.11 ERA, 1.56 WHIP and 123:77 K:BB in 122.2 innings between Double-A Chattanooga and Triple-A Louisville. Recent reports have suggested that he added an encouraging amount of velocity to his arsenal over the winter.
Feb 21, 2023
Increased fastball velocity
Williamson threw his fastball with more velocity than last spring in Saturday's live batting practice session, Charlie Goldsmith of The Cincinnati Enquirer reports. "He has a really good feel for all of his pitches," Reds catcher Luke Maile said. "He threw a few changeups that were outstanding. He's moving his fastball around really well. He has such a clean delivery."
ANALYSIS
Williamson is hoping to win a spot in the Reds rotation, though he's likely behind Luis Cessa and Luke Weaver among others for the final two spots. He had a tough 2022 campaign as he advanced levels in a new organization after the Reds traded for him last spring, but said that he's improved his throwing routine. "Last year, I'd do the same thing every day," Williamson said. "It was pretty light. Not enough. It wasn't very good. Now I have a very structured shoulder program to go off of. A structured shoulder program that goes up and down based on when I'm throwing."
Nov 15, 2022
Shielded from Rule 5 Draft
Williamson was added to the Reds' 40-man roster Tuesday.
ANALYSIS
Williamson split time between Double-A Chattanooga and Triple-A Louisville in 2022, recording a 4.11 ERA and 1.56 WHIP between the two levels. Giving batters a free pass to first has been his biggest issue lately, putting up an alarmingly-high 6.04 BB/9 in Triple-A last season. The 24-year-old lefty will need to bring that number down before he's ready to face MLB hitters with sustained success.
Jul 14, 2022
Finds success in second Triple-A start
Williamson worked six innings in his second start for Triple-A Louisville on July 8, striking out four while allowing one earned run on six hits and one walk.
ANALYSIS
Williamson was roughed up for four runs in four innings in his first start with Louisville earlier this month, but the 24-year-old lefty showed better form his second time out with the Triple-A club and tied a season high by covering six frames. He was promoted to Louisville on June 28 after submitting a 4.14 ERA, 1.50 WHIP and 74:40 K:BB across 67.1 innings in 14 outings with Double-A Chattanooga.
Jun 3, 2022
Working around control issues
Williamson has a 3.97 ERA, 1.46 WHIP and 48:25 K:BB across 45.1 innings for Double-A Chattanooga.
ANALYSIS
The 24-year-old lefty never ran into significant control issues when he was in the Mariners organization, but this year has been different. Williamson's issued at least three walks in five of his nine starts, but on the bright side, three of those came in his first four outings of the season. Across his last five games, he's put up a 2.48 ERA, 1.21 WHIP and 29:10 K:BB over 29 innings, which is closer to what the Reds expected from him. If he can find a way to keep the walks in check consistently, he should move up to Triple-A at some point this summer.
Mar 14, 2022
Traded to Cincinnati
Williamson, Jake Fraley and Justin Dunn were traded from the Mariners to the Reds on Monday in exchange for Jesse Winker and Eugenio Suarez, Mark Feinsand of MLB.com reports.
ANALYSIS
Williamson was one of Seattle's top pitching prospects and is a key piece of the deal for Cincinnati. The 23-year-old began 2021 at the High-A level before being promoted to Double-A, where he rebounded from tough start at finished with a 3.48 ERA, 1.27 WHIP and 94:23 K:BB across 67.1 innings (13 starts). A 2019 second-round pick, Williamson has limited professional experience and is likely a year away from seeing the majors.
Jul 13, 2021
Challenged at Double-A
Williamson has had a tough time in his first three Double-A starts, giving up 11 runs on 18 hits with a 13:6 K:BB through 14 innings.
ANALYSIS
That stands in stark contrast to his performance with High-A Everett, where Williamson pitched to a 3.19 ERA and 1.00 WHIP with a mind-bending 17.1 K/9. The big lefty has certainly been hit hard since being promoted to Double-A, but it's a small sample, and it wouldn't be surprising to see him get right soon. There's a fairly high level of variance with Williamson, as he could end up as a mid-rotation starter or a bullpen guy. As is often the case for pitching prospects, command refinement and further development of his offspeed stuff are the keys to his future.
Mar 6, 2021
Joining major-league camp
Williamson has been invited to major-league spring training, Ryan Divish of The Seattle Times reports.
ANALYSIS
Williamson will join the team's major-league camp for the final few weeks of spring training, although he won't appear in any Cactus League games. He'll likely begin the regular season at the High-A or Double-A level after working with the big-league coaching staff this spring.
