Gelof (ribs) is likely to be activated from the 60-day injured list sometime during this weekend's series versus the Giants, Martin Gallegos of MLB.com reports.

Gelof will play nine innings with Triple-A Las Vegas on Wednesday for the second straight day. Assuming he comes out of that game without any issues, he will be set to make his season debut for the Athletics this weekend. Gelof initially landed on the IL back in March due to a fractured hamate bone before a stress reaction in his ribs extended his absence. The 25-year-old has slashed .263/.453/.421 with one home run and three stolen bases in 13 rehab contests. Once activated, Gelof is likely to soak up the bulk of the playing time at second base for the Athletics.

Frazier is out of the lineup for Wednesday's game against the Cardinals.

The left-handed-hitting Frazier will hit the bench for the Pirates' third straight matchup with a right-hander (Sonny Gray) and appears to have moved back into a utility role. Though he's posted a .762 OPS while batting .306 dating back to May 20, Frazier has been overtaken in left field by Tommy Pham, who offers more power upside with four extra-base hits (two home runs, two doubles) in his last seven contests.

Garcia is absent from the lineup for the first game of Wednesday's doubleheader versus the Tigers.

The left-handed-hitting Garcia will sit out the first game of the day, but he should be back in the lineup for the nightcap against right-hander Jack Flaherty. Amed Rosario will start at second base and bat third in the matinee.

Gimenez went 2-for-3 with a walk, a three-run home run and two additional runs scored in Tuesday's win over the Yankees.

The second baseman took Max Fried deep in the fourth inning, one of three Blue Jay long balls in a 12-5 rout. Gimenez has started to find a groove at the plate, batting .300 (9-for-20) over his last eight starts, but on the season he's still slashing a poor .207/.293/.315 with five homers, 10 steals, 21 RBI and 25 runs in 59 contests.

Triple-A Scranton/Wilkes-Barre placed Shewmake on its 7-day injured list Wednesday due to an unspecified injury.

Shewmake possesses a spot on the Yankees' 40-man roster but has spent the entire 2025 season in the minors. Over his 173 plate appearances with Scranton/Wilkes-Barre, Shewmake has slashed .235/.324/.379 with four home runs and nine stolen bases.

The Phillies acquired Walton from the Mets on Tuesday in exchange for cash considerations.

Walton has spent all of this season at Triple-A Syracuse, where he's slashed .222/.315/.377 with 11 home runs over 73 games. The 31-year-old can play every infield positions and also left field, giving the Phillies some experienced utility depth at Triple-A Lehigh Valley.

The Giants placed Koss on the 10-day injured list Tuesday with a left hamstring strain, Justice delos Santos of The San Jose Mercury News reports.

Koss had to make an early exit from Monday's game after injuring his hamstring during his third at-bat, and he'll now be forced to sit out at least another 10 days. With Matt Chapman (hand) and Casey Schmitt (wrist) also on the IL, Wilmer Flores is likely to see some time at third base in the near future. Meanwhile, Luis Matos will come up from Triple-A Sacramento to replenish the Giants' bench depth.

The Astros recalled Whitcomb from Triple-A Sugar Land on Tuesday, Brian McTaggart of MLB.com reports.

He's absorbing the roster spot vacated by the injured Jeremy Pena (rib). Whitcomb is hitless in nine at-bats with the Astros this season but has put up a .942 OPS with 19 home runs in 264 plate appearances with Sugar Land. The 26-year-old could be mixed in at a few positions in Houston.

The Marlins optioned Winkler to Triple-A Jacksonville on Tuesday.

Winkler was with the big club for a month but made just four starts, going 1-for-11 at the dish. He's clearing out to make room on the roster for Derek Hill's (wrist) return.

The Brewers selected Seigler's contract from Triple-A Nashville on Tuesday.

Seigler is a versatile player capable of handling catcher, second base and third base. He's a switch hitter but is a much better hitter from the left side of the plate, as he posted a .975 OPS against righties as compared to a .445 OPS versus lefties this season at Nashville. The 26-year-old is also a capable baserunner, having gone 20-for-23 on stolen-base attempts over 63 games in 2025. Seigler will be making his major-league debut when/if he gets into a game.
