Peguero

Peguero emerged as a reliable reliever for the Giants in the second half of last year and was supposed to be in the late-game mix to open this year, but his hamstring shut him down since early in camp. He has been throwing recently, and it’s possible he’ll return before the end of April.

Peguero is facing a multi-week absence and is a virtual lock to open the regular season with a trip to the injured list. The 28-year-old righty has been battling a hamstring issue in recent weeks and finally underwent an MRI that revealed the severity. He posted a strong 2.43 ERA – 3.43 xERA – across 22 1/3 innings over 17 appearances for the Giants in his big-league debut last year.

The 28-year-old right-hander reported feeling significant improvement from the tight left hamstring that had sidelined him during the week. He still has plenty of time to ramp up in time for the start of the regular season.

The Giants are going to keep him limited over the next week or so in an effort to combat the issue. Peguero is expected to be a key cog in the club’s bullpen for the 2026 season, so they’ll need to make sure that he’s healthy and ready to go by the end of March.

Peguero made a strong impression back in spring training after signing a minor league contract with the Giants and receives his first call-up to the big leagues after compiling a pedestrian 5.10 ERA across 42 1/3 innings (35 appearances) this season on the doorstep of the majors. The 28-year-old righty will operate in middle relief for San Francisco.

The 27-year-old hurler spent the 2024 campaign in the Tigers’ organization where he registered a 3.14 ERA, 1.22 WHIP and a 56/17 K/BB ratio across 51 2/3 innings in 43 appearances at Double-A Erie. He’ll function as extra bullpen depth for the Giants in the upper minors.

The 26-year-old hurler did not receive an invitation to big league camp. Peguero spent the 2023 season in the Nationals’ organization where he posted a 4.62 ERA, 1.64 WHIP and a 40/27 K/BB ratio over 50 2/3 innings between Double-A Harrisburg and Triple-A Rochester. He’ll add bullpen depth in the upper minors for the Tigers.

Peguero was traded to the Rockies from the Rays last August and reached minor league free agency this offseason. The 25-year-old righty heads to the Nationals as extra organizational relief depth after compiling a pedestrian 4.76 ERA, 1.69 WHIP and 52/35 K/BB ratio across 56 2/3 innings (50 appearances, four starts) last season at the Triple-A level.

It’s a rare post-trade deadline deal. Peguero has compiled an underwhelming 4.58 ERA, 1.55 WHIP and 33/24 K/BB ratio across 39 1/3 innings (32 appearances) this season for Triple-A Durham. The 25-year-old righty will give the Rockies some extra organizational relief depth.
