Tigers pitcher Casey Mize, the first overall pick in 2018, will undergo Tommy John surgery

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.

Dr. Keith Meister, the team physician for the Texas Rangers, determined Mize needed elbow surgery. The procedure will occur “pretty soon,” Hinch said, but the exact date is unclear. The recovery process usually takes 12-18 months, meaning Mize is unlikely to return to the Tigers until 2024.

“He still doesn’t have a torn ligament,” Hinch said. “Dr. Meister has diagnosed him with a stretched ligament that’s lost its elasticity and functionality inside his elbow. Any of the exams we’ve had, it’s shown an intact ligament, which is true. But the symptoms continue to recur.”

Mize, the 2018 No. 1 overall pick, hasn’t pitched for the Tigers since April 14 against the Kansas City Royals at Kauffman Stadium. The 25-year-old landed on the injured list April 15 with a right elbow sprain.
