Joel Peguero: Everything you need to know

The Giants reinstated (hamstring) from the injured list Tuesday, Justice delos Santos of The San Jose Mercury News reports. Peguero has been on the injured list since the beginning of the season due to a Grade 2 hamstring strain he suffered during spring training. He started up a rehab assignment at Triple-A Sacramento on April 7 and will now return to the Giants after posting a 4.82 ERA and 0.86 WHIP through 9.1 frames in the minors. The 29-year-old righty held his own in the big leagues last season, posting a 2.42 ERA and 1.03 WHIP over 22.1 innings, and he'll likely work in a setup or middle-relief role with San Francisco.

Peguero (hamstring) earned a hold and struck out two in a scoreless inning during Triple-A Sacramento's 5-3 win over Las Vegas on Tuesday. 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.

Peguero (hamstring) will start a rehab assignment with Triple-A Sacramento on Tuesday, Alex Pavlovic of NBC Sports Bay Area reports. Peguero opened the regular season on the 15-day injured list due to a Grade 2 left hamstring strain that he aggravated in early March. He's eligible to return from the IL in mid-April but will likely need to have at least a couple of rehab outings under his belt before being cleared to make his 2026 regular-season debut. Peguero made his major-league debut Aug. 21 and appeared in 17 games for the Giants in 2025, finishing with a 2.42 ERA, 1.03 WHIP, four holds and a 17:8 K:BB across 22.1 innings.
