The Tigers placed Mize on the 15-day injured list Friday with right adductor inflammation, retroactive to Thursday.
Mize left his start against the Angels on Wednesday with groin tightness, and although an MRI didn't reveal a strain, he'll still end up on the injured list while the Tigers treat his inflammation. Beau Brieske (thigh) was activated from the 60-day IL in a corresponding move, though it remains unknown who will take Mize's place in Detroit's rotation.
