Altuve (foot) will start at second base and bat cleanup in Monday's game against the Rangers, Chandler Rome of The Athletic reports.

Altuve was held out for Sunday's 8-3 loss to Atlanta after he was still experiencing soreness on the bottom of his right foot following his early exit a day earlier, but the one start off appears to have provided sufficient healing time for the 35-year-old. The Astros' decision to use him at second base rather than at designated hitter in his return to the lineup supports the notion that he's feeling healthy heading into a six-game homestand against the Rangers and Mariners this week.

The Cardinals optioned Fermin to Triple-A Memphis on Monday.

With St. Louis bringing back Nolan Arenado (shoulder) from the 10-day injured list, Fermin was an expendable piece in the Cardinals infield. After receiving a promotion from Memphis on Saturday, Fermin appeared in one of the Cardinals' final two games of the series in Milwaukee over the weekend, going 2-for-3 with an RBI and a stolen base.

Gonzales went 1-for-4 with a triple and two RBI on Sunday against the Nationals.

Gonzales got the Pirates on the board with a two-RBI triple in the first inning, his fourth extra-base hit in his last eight games. He's hit a solid .282 since the All-Star break, but he has only one home run with 13 RBI and 23 runs across 49 games in that span.

Vargas replaced Blaze Alexander (elbow) at second base in the fourth inning Sunday and went 1-for-3 in a 6-4 win over Minnesota.

Alexander was removed from the game after getting hit by a pitch in the elbow/forearm area. Testing came back negative, but the elbow showed significant swelling, per Steve Gilbert of MLB.com. Vargas could benefit from any time Alexander misses, but second base is typically Ketel Marte's realm.

Hoerner went 2-for-4 with a double and three RBI in Sunday's 4-3 win over the Rays.

The infielder came up clutch for Chicago, driving in three of the team's four runs, beginning with an RBI single in the first inning to score leadoff-man Michael Busch. Hoerner later delivered the decisive blow in the seventh, lacing a two-run double that gave the Cubs a lead they wouldn't surrender. The 28-year-old has been a steady force at the plate of late, recording hits in 18 of his last 21 games, including 10 multi-hit efforts. Over that span, Hoerner is batting .354 with 10 RBI, 16 runs scored, nine doubles and four stolen bases across 91 plate appearances.

Triple-A Columbus placed Bazzana on its 7-day injured list Sunday due to left flank soreness.

Bazzana suffered the injury Thursday and will miss the final week of the Triple-A season, but because the Guardians are labeling the issue as a sore flank, the 23-year-old shouldn't require as much recovery time as he needed for the internal right oblique strain that kept him out for nearly two months earlier in 2025. The No. 1 overall pick in the 2024 First-Year Player Draft had a rough introduction to the Triple-A level upon his promotion from Double-A Akron on Aug. 11, but he had settled in nicely in September, slashing .290/.421/.742 with four home runs over his final nine games with Columbus.

Fermin went 2-for-3 with a stolen base and one RBI in Sunday's 3-2 win versus the Brewers.

The St. Louis infielder tallied his second steal of the season, taking second off Milwaukee starter Jose Quintana in the second inning. Fermin was subsequently caught stealing when trying to nab home later in the frame. Fermin, who is now slashing .298/.389/.404 in 55 total plate appearances, is in a bench role currently for the Cardinals. He could become an intriguing fantasy option for batting average and speed since he hit .305 with 20 steals in 289 Triple-A plate appearances this season.

Moore went 1-for-4 with a solo home run in Sunday's 11-2 loss to the Mariners.

This was Moore's second game in the lineup since getting recalled from Triple-A Salt Lake. He hit just .175 with 15 strikeouts over 10 games during his stint in the minors, but it looks like he'll get the chance to reclaim a starting job at second base to close out 2025 in the majors. For the season, he's at a .192/.285/.350 slash line with five homers, 13 RBI, 16 runs scored, two doubles, one triple and no stolen bases over 138 plate appearances at the big-league level.

Rengifo is out of the lineup for Sunday's game against the Mariners.

For the second day in a row, Rengifo will take a seat in favor of rookie Christian Moore, who will cover second base and bat fifth in the series finale. At 69-80, the Angels are effectively eliminated from playoff contention, so it wouldn't be surprising if the club moved Rengifo into a utility role over the final two weeks in order to open up regular playing time for Moore, who is viewed as the organization's long-term future at the keystone.

Gelof is out of the lineup for Sunday's game against the Reds.

Darell Hernaiz will slide over from his usual post at third base to cover the keystone in place of Gelof, who had started in every game since being called up from Triple-A Las Vegas on Aug. 25. In the three weeks following his promotion, Gelof is hitting .230 with two home runs, one steal, eight runs and six RBI while striking out at a 43.9 percent clip over 17 games.
