Giants Call Up Flamethrower Peguero After Roupp Injury

The San Francisco Giants have called up hard-throwing right-hander Joel Peguero from Triple-A Sacramento to make his Major League debut, prompted by an injury to right-hander Landen Roupp who sprained his left knee. Peguero, known for his triple-digit fastball and strong spring training performance that earned him the 2025 Barney Nugent Award, struggled early in the minor league season but has improved significantly since July. To clear roster space, the Giants optioned right-hander Kai-Wei Teng and outfielder Grant McCray to Triple-A, recalled outfielder Luis Matos, and transferred reliever Erik Miller to the 60-day injured list due to left elbow inflammation likely ending his season. Rookie left-hander Carson Whisenhunt is set to start in place of Roupp, while third baseman Matt Chapman is on track to return soon. The Giants hope these moves will stabilize the bullpen and outfield as they navigate injuries and look to bolster their pitching staff.
