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 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.

Fitzgerald went 2-for-3 with two doubles and two RBI in Monday's 4-2 loss to the Diamondbacks.

Called up from Triple-A Sacramento before Monday's game, Fitzgerald lined a double to left field in the fifth inning. He then added a two-run double in the seventh to tie the game at 2-2. The 27-year-old infielder delivered his first multi-hit performance since June 11 after going 0-for-11 in his last six big-league appearances. Fitzgerald appeared in 21 games in June, slashing .155/.219/.207 with five RBI, three doubles, two runs scored and two stolen bases across 68 plate appearances during that span.

Wetherholt has been selected to represent the Cardinals in the All-Star Futures Game, Derrick Goold of the St. Louis Post-Dispatch reports.

Wetherholt has been excellent at Double-A Springfield in his first full pro season, slashing .305/.430/.453 with five home runs, 13 stolen bases and a 35:41 K:BB. The No. 7 overall pick in the 2024 First-Year Player Draft, Wetherholt dealt with hamstring issues in college at West Virginia, but he has stayed healthy in pro ball. The 22-year-old could be considered for a promotion to Triple-A Memphis soon.

McLain went 3-for-5 with a double, two RBI and a run scored in Monday's 13-6 loss to Boston.

McLain has cooled off a bit since he was moved from the bottom of the order to second, but he's still hitting much better than he was through much of April and May. In the eight games since the promotion, McLain is batting .250 (8-for-32) with a home run, a double, four RBI and six runs scored. His .213 batting average is the highest its been since early April.

Koss suffered a left hamstring injury in Monday's 4-2 loss to the Diamondbacks and won't be available to play Tuesday, Justice delos Santos of The San Jose Mercury News reports.

Koss tweaked his hamstring while running out a groundout during his third at-bat of the game, but he was able to stay in the contest and later hit a ground-rule double in the top of the eighth before Brett Wisely was called upon off the bench to pinch run for him. It's unclear if Koss will need to head to the injured list, as the Giants will presumably send him in for further testing before making a decision. The loss of Koss even for just one game will significantly test the Giants' depth at third base, where Casey Schmitt (wrist) recently joined Matt Chapman (hand) on the injured list. Wisely played the final inning of Monday's game at third base and will presumably be the top option to start at the position Tuesday.

Stott went 1-for-3 with a steal, a walk and a run scored in Monday's 4-0 win versus the Padres.

Stott swiped his second base of the month when he took second off San Diego starter Matt Waldron in the fourth. June was tough for the Philadelphia second baseman, as he entered this contest with an anemic .210/.289/.272 slash line over 90 plate appearances. Perhaps this stolen base, his first since June 18, can kickstart Stott, who now sports a .244 average, five homers, 36 runs scored and 35 RBI while going 13-for-16 on steal attempts across 77 games.

Wisely is out of the lineup for Monday's game against the Diamondbacks.

Wisely went 3-for-12 with a double, three walks and two RBI while starting each of the Giants' last four games at second base, but he'll hit the bench in Monday's series opener. Though Casey Schmitt (wrist) joined Matt Chapman (hand) on the injured list Monday to open up an everyday role at third base for Christian Koss, Wisely's playing time at the keystone could be threatened by the arrival of Tyler Fitzgerald, who was recalled from Triple-A Sacramento. Fitzgerald will get the start at second base Monday and will bat seventh.

Fitzgerald was called up from Triple-A Sacramento prior to Monday's series opener with the Diamondbacks, John Shea of the San Francisco Chronicle reports.

Fitzgerald will officially return to the major-league roster after being sent down June 23. The 27-year-old will look to improve upon the .230/.289/.320 slash line he posted over 178 at-bats in 57 games with the Giants so far this season. Fitzgerald will replace Casey Schmitt (wrist) with the big-league club after Schmitt was placed on the 10-day injured list Monday.
