San Francisco Giants

Jose Butto

RP

Butto previously had a blood clot removed from his arm, and his latest procedure will require 5-to-6 months of rehab, meaning he won't be able to make it back before the end of the season. He'll end 2026 with five earned runs allowed over just two innings.

Daniel Susac

C

Susac has gone 11-for-23 at the plate in the big leagues this season and seemed to be on his way toward splitting reps behind the plate with Patrick Bailey, but the former will now have to wait at least 10 days before he gets another opportunity to start. Eric Haase will come up from Triple-A Sacramento to give the Giants depth at catcher.

Jared Oliva

OF

The common recovery timeline for this type of procedure is 4-to-6 weeks, so Oliva will be out until mid-May even in a best-case scenario. He is 1-for-7 at the plate this season in his limited opportunities for the Giants.

Sam Hentges

RP

After tossing a scoreless inning for Single-A San Jose on Sunday, Hentges advanced to Sacramento for the next step of his rehab assignment and threw eight of his 13 pitches for strikes. The 29-year-old southpaw hasn't pitched in a big-league game since 2024 but appears to be trending in the right direction after undergoing left shoulder surgery in September 2024 and arthroscopic right knee surgery in August 2025.

Harrison Bader

LF

It helps explain why he's out of the Giants' lineup Tuesday for the second straight game. Bader first tweaked his hamstring less than a week before Opening Day, and it seems the injury is still bothering him. It could at least partly explain the veteran outfielder's lackluster .115/.145/.192 batting line in his first 15 contests this season. At this point, it does not seem the injured list is under consideration for Bader. Jared Oliva is starting in center field and batting ninth Tuesday in Cincinnati in Bader's absence.

Joel Peguero

RP

Peguero was placed on the 15-day injured list March 25 (retroactive to March 22) with a Grade 2 left hamstring strain and began a rehab assignment with the River Cats on Tuesday. The right-hander experienced hamstring tightness in mid-February and didn't play in any Cactus League games before ultimately landing on the injured list, but he appears to be trending in the right direction. The 28-year-old made his big-league debut in 2025 with the Giants, recording a 2.42 ERA, 1.03 WHIP and 17:8 K:BB across 22.1 innings in 17 outings.

Parks Harber

3B

One of the top position prospects in the Giants organization, Harber wasn't in serious consideration for a spot on the Opening Day roster but had impressed nonetheless throughout the spring, slashing .357/.424/.571 over 33 Cactus League plate appearances before sustaining the hamstring injury Saturday. He now appears on track to miss at least the first month of the minor-league season while recovering from the injury, but once he's back to full health, Harber is expected to report to Double-A Richmond, according to Pavlovic.

Jason Foley

RP

Foley continues to recover from right shoulder surgery that he underwent in May of 2025. He opened the 2026 season on the 60-day IL, and while he's not expected to be ready for major-league action until at least midseason, it's encouraging to see that he has progressed enough in his rehab to toss a bullpen session.

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.

Reiver Sanmartin

RP

The southpaw will be sidelined until June after suffering a right hip flexor strain earlier this month. Once healthy, Sanmartin is not a given to return to the active roster with the big club.

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.

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.
