Cleveland Guardians ace Shane Bieber will undergo season-ending Tommy John surgery on his throwing elbow, the team announced Saturday.

The 2020 AL Cy Young Award winner was limited to 21 starts last season due to right elbow issues.

Bieber’s 2024 season ends with a 2-0 record after 12 scoreless innings, 20 strikeouts and one walk.

“He's devastated by it,” Guardians president of baseball operations Chris Antonetti told reporters on a video call. “He feels as though he is letting a lot of people down. And I tried to reassure Shane that couldn’t be further from the truth because he embodies what it means to be a professional, what it means to be a great teammate and a great leader."

A two-time All-Star, Bieber has been one of baseball’s best pitchers over the last several seasons when healthy, and his 2.91 ERA since 2020 ranks second only to Corbin Burnes’ 2.85.

Bieber, 28, is just the latest notable pitcher to be diagnosed with elbow issues.

New York Yankees flamethrower and reigning AL Cy Young Award winner Gerrit Cole has been shut down at least until June, while the Atlanta Braves’ Spencer Strider will undergo tests after feeling elbow discomfort in Friday’s start.

The Florida Marlins announced Thursday that touted right-hander Eury Perez will need Tommy John surgery.
