Productive in Wednesday's loss
Gelof went 2-for-4 with a solo home run and a stolen base in Wednesday's 6-3 loss to the Mariners.
ANALYSIS
He took George Kirby deep in the fourth inning to get Oakland on the board, but Gelof's squad was already down 2-0 at that point. The rookie second baseman is batting .310 (22-for-71) in September as he puts the finishing touches on an impressive MLB debut that has seen him rack up 13 homers and 13 steals in just 59 games.
Sep 19, 2023
Earns 12th steal
Gelof went 1-for-3 with a walk and a stolen base in Monday's 5-0 loss to the Mariners.
ANALYSIS
Gelof has continued to hit well in September, going 18-for-63 (.286) with two home runs and three steals over 16 contests this month. The second baseman has picked up two of those steals over his last four games.

Registers 11th steal
Gelof went 1-for-3 with a walk and a stolen base in Friday's 8-3 loss to the Padres.
ANALYSIS
Gelof recorded his first game this month with just one hit -- he had seven multi-hit efforts and five hitless games to begin September. His power has taken a dip this month with six doubles and one home run over 13 contests, and this was his second steal in that span. Gelof is at a .268/.335/.516 slash line with 11 homers, 11 steals, 25 RBI and 33 runs scored through 54 games this season.
Sep 10, 2023
Continues to shine
Gelof went 2-for-4 with a two-run home run and a walk Saturday in a loss to the Rangers.
ANALYSIS
Gelof was responsible for all of Oakland's run output in the contest, drilling a game-tying two-run shot in the seventh inning. He finished with multiple hits for the sixth time in his past eight games, a span during which he's batting 12-for-34 (.353) with four RBI and five runs scored. The only thing that had been missing of late was the long ball -- prior to Saturday's homer, Gelof hadn't gone deep since Aug. 24, a stretch of 13 contests.
Sep 5, 2023
Reaches double-digit steal mark
Gelof went 2-for-5 with a stolen base in an extra-inning loss to the Blue Jays on Monday.
ANALYSIS
Gelof's third multi-hit effort in the last four games included his 10th stolen base in the first 11 attempts of his career. The rookie's pair of knocks Monday were both singles, but Gelof has impressively laced more than half (25) of his 48 hits thus far for extra bases, making him an extremely well-rounded fantasy contributor right from the onset of his career.
Sep 4, 2023
On base thrice in win
Gelof went 2-for-4 with a walk and two runs in a win over the Angels on Sunday.
ANALYSIS
Gelof played some small ball Sunday and teed up a couple of teammates for RBI with his pair of singles. The rookie recently went through a brief 1-for-18 funk over a five-game span, but he's bounced back with a pair of two-hit tallies in his last three contests and carries an impressive .266/.330/.532 slash line across his first 191 big-league plate appearances.
Sep 2, 2023
Multi-RBI effort in win
Gelof went 2-for-5 with a two-run double, another two-bagger and a run in a win over the Angels on Friday.
ANALYSIS
Gelof's fourth-inning two-bagger knocked in Esteury Ruiz and Jonah Bride to cap off a five-run outburst. The rookie pushed his RBI total to an impressive 23 with the timely two-bagger and snapped a rare 1-for-18 slump that had encompassed his last five games as well. Gelof has demonstrated a welcome knack for clutch hitting early in his career, posting a .905 OPS across his first 43 plate appearances with men in scoring position.
Aug 29, 2023
Grabs steal in loss
Gelof went 1-for-4 with a stolen base in Monday's 7-0 loss to the Mariners.
ANALYSIS
Gelof's bat has cooled off a bit lately -- he's gone eight games without a multi-hit effort. He's added just two steals while batting .156 (5-for-32) in that span. For the season, the second baseman has a .276/.343/.566 slash line with nine steals, 10 home runs, 21 RBI and 24 runs scored over 39 contests.
Aug 25, 2023
Continues solid rookie campaign
Gelof went 1-for-4 with a two-run home run against the White Sox in an 8-5 win Thursday.
ANALYSIS
Gelof's seventh-inning two-run shot was a big one, as it broke what had been a 5-5 tie. It was the rookie's 10th long ball in just his 35th major-league game -- no other player in Athletics history has achieved that feat, per the team's PR department. Gelof has added 24 runs, 11 doubles, 19 RBI, eight thefts and a .294/.360/.610 slash line while providing considerable excitement for what has otherwise been a dismal season in Oakland.
Aug 23, 2023
Picks up eighth steal
Gelof went 1-for-3 with a stolen base, a walk and a run scored in Tuesday's 5-4 win over the Royals.
ANALYSIS
Gelof continues to do it all for the Athletics. He's gone 23-for-59 (.390) with four home runs and three steals over his last 15 games. The second baseman is up to eight thefts, nine homers, 17 RBI, 23 runs scored and a steady .305/.373/.617 slash line through 33 contests this season, cementing himself firmly as a starter and the No. 2 hitter in the lineup.
Aug 22, 2023
Belts ninth homer
Gelof went 1-for-5 with a solo home run in a 6-4 win against Kansas City on Monday.
ANALYSIS
Gelof gave Oakland a 2-1 lead in the third inning with his 428-foot solo shot to center field. The rookie has gone deep nine times in his first 32 MLB games, outdoing the pace he set by hitting 12 long balls over 69 contests with Triple-A Las Vegas prior to getting called up. Gelof has been red-hot of late, batting .441 (15-for-34) with three homers, three doubles, six RBI and a stolen base over his past eight games.
Aug 17, 2023
Keeps raking Wednesday
Gelof went 4-for-5 with two doubles, a run scored, two RBI and a stolen base in Wednesday's 8-0 win over the Cardinals.
ANALYSIS
The rookie second baseman has been on fire since the calendar flipped to August. Over his last 14 games, Gelof is slashing .370/.424/.778 with 12 of his 20 hits (seven doubles and five homers) going for extra-bases, and he's added 10 runs, 10 RBI and two steals for good measure. The A's have cycled through a number of young position players this season with erratic results, but Gelof is quickly emerging as the best of the bunch.
Aug 14, 2023
Homers twice Sunday
Gelof went 4-for-5 with two home runs in Sunday's 8-7 loss against the Nationals.
ANALYSIS
Gelof opened the scoring with a solo home run off Trevor Williams in the first inning before adding a second long ball in the fifth. The 23-year-old second-baseman is up to eight homers this season, with three coming in his last four games. Gelof's now slashing .281/.343/.635 with 18 runs scored, 13 RBI and six stolen bases across 105 plate appearances in an impressive rookie campaign.
Aug 10, 2023
Smacks sixth homer Wednesday
Gelof went 1-for-4 with a solo home run in a win over the Rangers on Wednesday.
ANALYSIS
Gelof made the most noise on either team during a night in which both teams were quiet offensively. The rookie has now left the yard in five of the last 11 games, and he's laced 13 of his first 21 big-league hits overall for extra bases.
Aug 7, 2023
Thrives in Sunday's win
Gelof went 3-for-4 with a double, a stolen base and two runs in a win over the Giants on Sunday.
ANALYSIS
Gelof authored one of a trio of three-hit efforts for the Athletics on the afternoon and his fourth multi-hit tally in the last seven games overall. The rookie has been as good as anticipated following his promotion from Triple-A Las Vegas, and he's opened August by going 7-for-18 with Sunday's double, two solo home runs, a pair of walks, Sunday's steal and four total runs over his first five games of the month.
Aug 2, 2023
Finding power groove
Gelof went 2-for-4 with a solo home run in Tuesday's 7-3 loss to the Dodgers.
ANALYSIS
Gelof homered for the third time in his last four games, though he's also struck out eight times without a walk in that span. The second baseman is already up to four homers in his first 15 major-league contests. He's batting .237 with seven RBI, 11 runs scored and five stolen bases. While a 32.8 percent strikeout rate is too lofty for long-term success, his mix of power and speed could be intriguing in many fantasy formats.
Jul 30, 2023
Busy in Saturday's win
Gelof went 2-for-6 with a solo home run, two stolen bases and three runs scored in Saturday's 11-3 win over the Rockies.
ANALYSIS
Gelof was able to make an impact with power and speed, providing a taste of what the top prospect can do at his best. He's homered in consecutive contests and is up to three long balls over 13 games in his big-league career. The second baseman has added five steals, six RBI and 10 runs scored through 56 plate appearances.
Jul 29, 2023
Launches second homer
Gelof went 1-for-5 with a two-run home run in a win over the Rockies on Friday.
ANALYSIS
Gelof squared up for his second career round-tripper in the fifth inning with Tony Kemp aboard to extend the Athletics' lead to 7-1 at the time. The rookie had gone into the game mired in a 1-for-12 slump that had encompassed his previous three games, although he'd reached safely in seven of his first eight big-league games prior to the brief skid. Gelof will undoubtedly continue to experience his share of bumps in the road as he acclimates to big-league arms, but he's demonstrated plenty of upside thus far by lacing seven of his first 10 hits for extra bases while also pulling off three steals in four attempts.
Jul 26, 2023
Picks up third steal
Gelof went 0-for-3 with a stolen base in Tuesday's 2-1 loss to the Giants.
ANALYSIS
Gelof's gone hitless in just three of his first 10 major-league games, with his 0-fer Tuesday ending a modest four-game streak. The second baseman was able to pick up his third steal and his first since he swiped two bags July 15. He's batting .250 with a home run, three RBI and six runs scored while often batting first or second in the Athletics' weak-hitting lineup.
Jul 23, 2023
Hits first major-league homer
Gelof went 2-for-3 with a solo home run, a walk and two total runs scored in Saturday's 4-1 win over the Astros.
ANALYSIS
Gelof padded the Athletics' lead in the seventh inning with his first major-league homer, which came in his eighth game. He's done a lot of other things right so far, racking up three doubles, a triple and two stolen bases while working as the primary second baseman since his July 14 debut, though he's also added a 4:9 BB:K. Trimming the strikeout rate will likely be a key to his fantasy usefulness, though his speed is already showing up after he stole 20 bases in 69 games for Triple-A Las Vegas.
Jul 22, 2023
On base thrice in loss
Gelof went 1-for-3 with two walks and a run in a loss to the Astros on Friday.
ANALYSIS
Gelof worked out of the No. 2 spot in the order for the third time in his first seven games and did a good job getting on base for the heart of the Athletics' lineup. That paid off on one of the three occasions the rookie reached safely, with Gelof crossing the plate with the fourth run of his big-league career on Jordan Diaz's bases-loaded walk in the fifth. Gelof has impressively gotten on in six of the first seven contests of his career and has already generated a trio of extra-base hits, although he's still in search of his first home run.
Jul 19, 2023
Resting Wednesday
Gelof is out of the lineup for Wednesday's game against the Red Sox.
ANALYSIS
Gelof will hit the bench for the first time since receiving a promotion from Triple-A Las Vegas following the All-Star break. While starting at second base in each of his first five big-league contests, Gelof went 4-for-19 with two doubles, one triple, one walk, three runs, two RBI and two stolen bases. Jordan Diaz will spell him at the keystone in the series finale.
Jul 16, 2023
Swipes two bags Saturday
Gelof went 1-for-4 with a triple, two stolen bases and two runs in a loss to the Twins on Saturday.
ANALYSIS
A day after lacing an RBI double in his big-league debut, Gelof had an even more impactful extra-base hit with his third-inning triple. The rookie then made the most of reaching via a fielder's choice groundout in the sixth, recording swipes of both second and third base -- the latter on a double steal in conjunction with Jace Peterson -- and subsequently coming home on a Nick Allen sacrifice fly. Gelof's early success is a potential boon for both the frequently run-starved Athletics and fantasy managers, and as he's already demonstrated, he's capable of contributing across the board offensively.
Jul 15, 2023
Makes impact in debut
Gelof, whose contract was selected from Triple-A Las Vegas earlier in the day, went 1-for-4 with an RBI double in his big-league debut against the Twins on Friday.
ANALYSIS
The 23-year-old prospect got his big-league career off to a noteworthy start by delivering an RBI double in his second plate appearance. Gelof had been running hot at the plate in Las Vegas with a .300 average and .921 OPS through 68 games, and he should get an extended look against big-league arms during the second half of the season.
Jul 14, 2023
Promotion official
Gelof's contract was selected from Triple-A Las Vegas ahead of Friday's game against the Twins.
ANALYSIS
Gelof, who is widely viewed to be Oakland's second baseman of the future, should play pretty regularly now that he's officially on the active roster. The righty-hitting 23-year-old slashed .304/.401/.529 with 12 home runs, 20 steals and a 27.9 percent strikeout rate in the hitter-friendly Pacific Coast League. A .410 BABIP propped up his batting average, but Gelof should at least chip in stolen-bases and occasional power as a rookie.
Jul 12, 2023
Coming up for MLB debut Friday
Gelof will be called up from Triple-A Las Vegas by the Athletics on Friday to make his major-league debut, Martin Gallegos of MLB.com reports.
ANALYSIS
Gelof, 23, has collected a .304/.401/.529 batting line with 12 home runs and 20 stolen bases at Vegas in the hitter-friendly Pacific Coast League this season. He's been particularly hot over his last 10 games with a .413/.426/.870 line, five homers and three steals. Gelof has played second base exclusively this season and should take over as the everyday player at the keystone for the A's. He'll be weighed down by his team and ballpark but nonetheless should be rostered in deeper fantasy leagues.
