Peguero (hamstring) threw a live batting practice session Friday and is on track to play this week, Maria Guardado of MLB.com reports.

The right-hander made 17 relief appearances for the Giants in 2025 after his contract was selected from Triple-A Sacramento in August, recording a 2.42 ERA, 1.03 WHIP and 17:8 K:BB across 22.1 innings.
