Giants manager Tony Vitello indicated Wednesday that Mayer (forearm) could return from the 10-day injured list and make his team debut Monday versus the Reds, Andrew Baggarly of The Athletic reports.

Vitello had previously floated the possibility of Mayer being activated from the 10-day injured list this weekend, and while a return to action for the team's series in Boston hasn't been ruled out, the Giants seem to be leaning toward waiting until the start of a homestand Monday to reinstate the infielder. Mayer has been out since late June with a left forearm stress reaction but has played four rehab games with Triple-A Sacramento, going 6-for-17 with one home run and a 2:9 BB:K while making three starts at second base and one at third base. Once activated, Mayer should be in line for an everyday role in the San Francisco infield.

The Rockies selected Manfredi's contract from Triple-A Albuquerque on Wednesday.

Manfredi joined the Rockies organization at the trade deadline as part of the deal that sent Antonio Senzatela to Milwaukee. The 26-year-old righty owns a 4.45 ERA and 1.38 WHIP across 28.1 innings at Triple-A this season but has given up six runs in just five frames with Albuquerque since being traded. Despite his recent performance, the Rockies will add him to their bullpen to provide a fresh arm. Parker Mushinski was designated for assignment in a corresponding move.

The Rockies optioned Shook to Triple-A Albuquerque on Wednesday.

Shook was recalled by the Rockies on Monday and pitched the same night against the Dodgers, allowing one run on two hits and one walk while striking out one batter across two innings. Colorado will shuffle its bullpen again Wednesday, with Shook going back down to the minors and left-hander Mark Manfredi coming up from Albuquerque to replace him. Shook has spent most of the 2026 season in Triple-A, where he has a 3.02 ERA, 1.33 WHIP and a 45:24 K:BB over 47.2 innings.

Hamilton is absent from the lineup for Wednesday's game versus the Mariners.

Hamilton typically starts against most righties, but with Cooper Pratt back from the injured list to take over at shortstop, Hamilton and Joey Ortiz will be mixed and matched at third base. It's Ortiz at the hot corner for the Brewers on Wednesday.

Mitchell is not in the lineup for Wednesday's contest against the Mariners.

Logan Gilbert is on the bump for the Mariners, marking the first time since July 7 that the left-handed-hitting Mitchell isn't starting versus a righty hurler. Luis Lara will handle center field and Jake Bauers will be in right field for Milwaukee.

The Giants optioned Sanmartin to Triple-A Sacramento on Wednesday.

Sanmartin will be squeezed off the 26-man active roster after the Giants needed to clear a spot for lefty Matt Wilkinson, who was called up from Triple-A to start Wednesday's game in Cleveland. After being summoned from Sacramento on Aug. 3, Sanmartin made eight relief appearances during his latest stint with the Giants, pitching to a 7.11 ERA, 2.05 WHIP and 6:2 K:BB over 6.1 innings.

The Giants claimed Abner off waivers from the Diamondbacks on Wednesday and optioned him to Triple-A Sacramento.

Abner will reclaim a 40-man roster spot with the move to San Francisco, though he'll have to wait a bit before making his debut with the Giants. The 24-year-old lefty reliever made eight appearances with Arizona at the big-league level this season, posting a 6.28 ERA, 1.53 WHIP and 6:8 K:BB over 14.1 innings.

The Giants transferred Susac (knee) from the 10-day injured list to the 60-day injured list Wednesday.

Susac's rookie season will officially come to a close after he was initially placed on the IL last week due to a left knee patella fracture. Per MLB.com, Susac appears set to avoid surgery but will spend the next three weeks resting and rehabbing before he resumes baseball activities. He looks like he could be in line for a fairly normal offseason, setting the stage for Susac to be ready to go for the start of spring training. A Rule 5 Draft pick over the winter, the 25-year-old catcher slashed .243/.289/.375 with three home runs, two steals, 22 RBI and 11 runs over 161 plate appearances with the Giants.

Adames (back) will start at shortstop and bat third in Wednesday's game against the Guardians.

He'll make his return to the lineup for the first time in a week after a bout with back spasms kept him on the bench for the Giants' last four games. With Adames back at his usual post at shortstop, Christian Koss will slide back over to third base Wednesday.

The Nationals optioned Cruz to Triple-A Rochester on Wednesday.

Cruz was part of the trade package that came back to Washington from the Yankees in the Aug. 3 deal that sent first baseman Luis Garcia to New York. In six appearances out of the Nationals bullpen, Cruz allowed five runs on nine hits and five walks with four strikeouts across four innings.
