San Francisco Giants

Tyler Mahle

SP

Mahle was wild in his first and only rehab start with Triple-A Sacramento on Tuesday in issuing five walks over three innings, but he managed to escape with only one run allowed. The right-hander threw 63 pitches in the outing, so he will not have a full workload at his disposal versus the A's. Vitello declined to reveal whose rotation spot Mahle will be taking, but it will likely be either Trevor McDonald or Adrian Houser getting the boot.

Heliot Ramos

LF

Ramos began his rehab assignment with Sacramento after landing on the 10-day injured list May 16 with a right quadriceps strain. The 26-year-old outfielder singled in the fifth before coming around to score, and he also drew a walk in the sixth. Before he was sent to the IL, Ramos slashed .267/.307/.424 with 20 RBI, 19 runs scored, four home runs and a 26.7 percent strikeout rate across 176 plate appearances.

Jason Foley

RP

Foley compiled a 2.89 ERA, 1.29 WHIP and 7:2 K:BB in 9.1 innings across his first nine rehab appearances between Sacramento and Single-A San Jose before being shut down earlier this month when he experienced renewed soreness in his right shoulder. The right-hander didn't pitch for eight days before being cleared to resume his rehab assignment over the weekend, and he seems to have come out of Friday's appearance no worse for the wear. Foley appears poised to return from the 60-day injured list and join the Giants bullpen at some point over the next two weeks.

Harrison Bader

CF

Bader will be shut down from baseball activities for the time being while he waits for the shot to take effect and relieve discomfort in his foot. While the Giants have yet to offer a formal timeline for Bader's projected return from the 10-day injured list, Alex Pavlovic of NBC Sports Bay Area relays that the veteran outfielder "doesn't sound like" he's close to playing again. The Giants should continue to get by with a platoon of Drew Gilbert and Jonah Cox in center field while Bader is on the shelf.

Keaton Winn

RP

It's uncertain when exactly the right-hander sustained the injury, but he last pitched Monday against Washington and surrendered three runs across two-thirds of an inning. According to Alex Pavlovic of NBC Sports Bay Area, manager Tony Vitello said an MRI on Winn's elbow didn't reveal anything overly concerning, leaving the Giants optimistic that the 28-year-old will be in line for a short-term absence. Winn will be eligible for reinstatement June 26.

Joel Peguero

RP

Peguero strained his left hamstring during the eighth inning of Sunday's win over the Rockies. The injury is severe enough for Peguero to go straight onto the 60-day IL, which means the earliest he's eligible to be reinstated is late July. Wilkin Ramos was called up from Triple-A Sacramento in a corresponding move.

Rowan Wick

RP

Wick's move to the 60-day IL was fully expected, as San Francisco signed him earlier this weekend with the knowledge that the right-hander would miss the entire 2026 season while recovering from Tommy John surgery, which he underwent in November. The 33-year-old's contract includes a club option for 2027, so the Giants will have the ability to closely monitor his rehab program in the months to come before deciding whether to retain him this winter. Wick hasn't pitched in the majors since 2022 but was one of the top relievers in Japan's Nippon Professional Baseball this past season, when he turned in a 1.13 ERA, 0.90 WHIP and 58:13 K:BB over 47.2 innings.

Hayden Birdsong

RP

Birdsong was diagnosed with a sprained UCL in mid-March and elected to go under the knife. The right-hander will miss the entirety of the 2026 campaign and likely at least the first couple months of 2027.

Randy Rodriguez

RP

The transaction frees a spot on the 40-man roster for Luis Arraez, whose signing was officially announced Tuesday. Rodriguez underwent Tommy John surgery last September and will miss the entire 2026 season.

Jose Butto

RP

Butto has already been ruled out for the rest of the season after undergoing surgery Saturday to repair an artery in his arm, so moving to 60-day IL has no impact on his timeline. He'll cede his spot on the 40-man roster to Eric Haase, who was selected from Triple-A Sacramento to replace Daniel Susac (elbow) on the active roster.
