Detroit Tigers right-hander Casey Mize’s early exit Tuesday night in Atlanta due to right groin tightness introduces a new variable into the team’s fragile rotation calculus. Mize departed in the third inning after appearing to labor on a pitch, and the Tigers announced he will undergo an MRI to determine the severity of the strain. For a franchise that has invested heavily in Mize’s development as a former No. 1 overall draft pick, any absence—even a brief one—tests the depth of a staff already navigating injuries. Groin injuries in pitchers can alter mechanics and lead to longer recovery if not managed precisely. The MRI results, expected within 48 hours, will define whether Detroit faces a short-term roster patch or a more significant disruption to its starting five in the weeks ahead.
