Mountcastle is out of the lineup for Wednesday's game against the White Sox.

Mountcastle is on the bench for the fourth time in five games and looks like he'll be limited to a part-time role down the stretch. Since returning from the injured list Aug. 8, Mountcastle has posted a .702 OPS, nearly 100 points above Coby Mayo's mark during that same stretch (.612 OPS). However, because Mayo is seen as a core building block for the Orioles, he'll continue to be prioritized as the team's everyday first baseman ahead of Mountcastle, who is entering his final year of arbitration in 2026 and could be a possible trade or non-tender candidate this offseason.

The Cardinals placed Contreras on the 10-day injured list Wednesday with a right shoulder strain.

The injury had previously been labeled as a biceps strain, but either way, it will end Contreras' season. He slashed .257/.344/.447 with 20 home runs and 80 RBI over 135 games in his first season as a full-time first baseman. Alec Burleson will take over at first base for the Cardinals down the stretch, which should lead to more playing time in the outfield for Jordan Walker.

Yorke will start in right field and bat seventh in Wednesday's game against the Cubs.

Yorke will stick in the lineup for the fifth straight contest and for the seventh time in eight games. He's yet to take advantage of receiving ample playing time in September, as he's slashing just .167/.189/.222 with no home runs, one stolen base, five RBI and one run in 37 plate appearances since being recalled from Triple-A Indianapolis at the start of the month.

Horwitz is out of the lineup for Wednesday's game against the Cubs.

The left-handed-hitting Horwitz will hit the bench for the series finale while the Cubs send southpaw Matthew Boyd to the bump. Rafael Flores will step in for Horwitz on Wednesday to make his first MLB start.

Steer (neck) will start at first base and bat seventh in Wednesday's game versus the Cardinals.

Steer had been scheduled to start Monday's game but was scratched due to neck spasms. However, he had a chiropractic adjustment Tuesday and is ready to play in Wednesday's series finale. Steer has been losing reps to Sal Stewart at first base, but Stewart will handle third base in Wednesday's contest.

The Cardinals will place Contreras (biceps) on the 10-day injured list Wednesday with a right biceps strain, Katie Woo of The Athletic reports.

The strain is considered mild, but it is bad enough to end the first baseman's season with less than two weeks remaining. Contreras will finish 2025 with a .257/.344/.447 batting line, 20 home runs and 80 RBI over 135 games. Alec Burleson will take over as the team's everyday first baseman down the stretch, opening up more playing time in the outfield for Jordan Walker and others.

Busch went 3-for-4 with a walk, a solo home run, two doubles and an additional run scored in Tuesday's 4-1 win over the Pirates.

Busch took Pittsburgh ace Paul Skenes deep to lead off the game, and he added two doubles to round out an excellent fantasy performance. The Chicago first baseman has now homered in consecutive games and three times in his last four contests. He's up to 29 long balls for the season, which is a new career best and tied for the team lead with Pete Crow-Armstrong.

Olson went 3-for-10 with a double, a triple, a home run, two runs scored and four RBI in Tuesday's doubleheader sweep of the Nationals.

After launching a solo shot off Jake Irvin in the matinee, Olson played hero in the top of the 10th inning in the nightcap with a bases-loaded triple. The first baseman has been on an absolute tear of late, batting .478 (11-for-23) over his last five games with eight of those hits going for extra bases (three doubles, a triple and four homers). On the year, he's up to 27 homers and 91 RBI in 152 contests, giving him a shot at his fifth career 30-HR campaign and fourth career 100-RBI season.

Torkelson went 4-for-5 with a two-run home run in Tuesday's 7-5, 10-inning loss to the Guardians.

Torkelson was dialed in all night as he delivered his first four-hit performance of the season. He saved his best for last, belting his 29th home run of the year in the bottom of the 10th inning as the Tigers tried to cut into a 7-3 deficit. Torkelson is now two away from tying his career high of 31 homers, which he recorded back in 2023. Tuesday's long ball snapped an 18-game stretch without a home run for the 26-year-old slugger.

Hernandez went 1-for-2 with a two-run home run and an additional RBI in Tuesday's 9-6 loss to the Phillies.

Hernandez continues to fill a versatile role for the Dodgers, but he hasn't hit well enough to stay in the lineup regularly since returning from an elbow injury. He's gone just 7-for-39 (.179) over 14 games since his return Aug. 26. The utility player has a .192/.248/.346 slash line with nine homers, 30 RBI, 26 runs scored and five doubles across 86 contests this season.
