Detroit Tigers right-hander Casey Mize will undergo Tommy John surgery, manager A.J. Hinch said Friday afternoon, to repair the ulnar collateral ligament in his throwing elbow.
He will miss the rest of the 2022 season.
Mize hasn’t pitched for the Tigers since April 14.
The 25-year-old landed on the injured list April 15 with a right elbow sprain. He was shut down twice during his throwing programs while rehabbing, most recently after a setback when he attempted to play catch from 90 feet on flat ground.
Mize, the 2018 No. 1 overall pick, has pitched 39 games for the Tigers in parts of three seasons, making his MLB debut in August 2020. He led the team with 30 starts and 150⅓ innings pitched last season.
