But on Tuesday, he suffered yet another setback.In his spring training debut against the Philadelphia Phillies, Giolito left after one inning after feeling tightness in his hamstring--tightness that the righty said he experienced on the very first pitch of the outing.

Giolito, who missed last season because of elbow surgery, spent much of the start of camp going through his rehab progression.

The top three of this rotation without Giolito are splendid. Garrett Crochet could very easily end up winning the AL Cy Young award after the Red Sox acquired him, Tanner Houck was an All-Star in 2024, and Walker Buehler has tremendous upside if healthy. Giolito figures to be the team's fourth starter when healthy.
