Walker went 2-for-4 with a two-run homer and an additional run scored during Houston's 6-2 win over Atlanta on Saturday.

Walker extended the Astros' lead to 6-0 in the third inning with a two-run shot off Bryce Elder. It was Walker's 23rd homer of the season, which is three shy from his 2024 total. He has gone 12-for-46 (.261) with one steal, two home runs, six RBI and eight runs scored in 12 games since the start of September.

Johnston went 2-for-4 with a walk, two home runs and three RBI in Saturday's 6-4 extra-innings win over the Tigers.

After taking Troy Melton deep for a solo shot in the sixth inning, Johnston walked it off in the 11th with a two-run homer off Rafael Montero. The 28-year-old rookie came into the game with just one long ball in his first 32 big-league contests, and the performance may have snapped a September swoon for Johnston in which he'd gone just 2-for-21 (.095) with zero RBI over his prior nine games.

Peraza isn't in the lineup for Saturday's game against the Mariners, Erica Weston of Bally Sports West reports.

After going 3-for-17 with seven strikeouts in his last five games, Peraza will stay put in the Angels' dugout Saturday while the team sends out Logan Davidson to cover first base.

Steer isn't in the lineup for Saturday's game against the Athletics.

Steer will take a seat on the bench Saturday after going 1-for-4 with a steal and two strikeouts in Friday's series opener. Sal Stewart will fill in as Cincinnati's first baseman and bat sixth.

The Giants placed Smith on the 10-day injured list Saturday with a right hamstring strain.

Smith injured himself while doing the splits to catch a throw from Matt Chapman during Friday's contest, and it will now cause him to miss at least 10 days while on the injured list. Rafael Devers will start at first base Saturday against Los Angeles and figures to do so more often until Smith returns. Meanwhile, Jerar Encarnacion (hamstring) will come off the IL to claim the open spot on the active roster.

Vaughn isn't in the lineup for Saturday's game versus the Cardinals.

The 27-year-old will miss a third consecutive start at first base Saturday in favor of Jake Bauers. Vaughn may continue to receive fewer starts going forward now that Bauers and Rhys Hoskins are both off the injured list, but he still seems to have a grip on regular playing time after appearing off the bench in each of Milwaukee's last two contests.

Mountcastle isn't in the lineup for Saturday's game against Toronto.

Mountcastle will take a seat Saturday after going 0-for-4 with a strikeout in Friday's series opener. Coby Mayo will start at first base and bat ninth.

Gonzalez (knee) will start at first base and bat leadoff against the Yankees on Saturday, Tim Healey of The Boston Globe reports.

Left knee soreness kept Gonzalez from playing in Boston's last two games, but he's been cleared to return to action Saturday. The 29-year-old is currently enjoying a 12-game hitting streak, during which he's slashed .455/.444/.545 with nine RBI and five runs scored.

Steer went 1-for-4 with a stolen base in Friday's 3-0 loss to the Athletics.

Steer has seen his playing time drop recently, with this being just his second start in the last five games, all against right-handed pitchers. Top prospect Sal Stewart has pushed Steer for playing time at first base rather than challenging Matt McLain at second. Steer has gone 5-for-18 (.278) over seven games in September, but it'll be tough for him to produce without a steady role in the lineup. For the season, the 27-year-old has a .237/.308/.396 slash line with 17 home runs, 64 RBI, 61 runs scored and seven steals over 134 games.

Crim went 1-for-4 with a three-run home run in Friday's 4-2 win over San Diego.

Making his Rockies debut, Crim got both his first major-league hit and homer courtesy of a fourth-inning jack. With Warming Bernabel (concussion) on the injured list, Crim has a chance to handle regular at-bats at first base in the interim. Crim has been very productive at the dish at the Triple-A level this season, slashing .281/.370/.494 with 21 big flies, 26 doubles and 85 RBI over 492 plate appearances.
