Guardians ace Shane Bieber will have season-ending Tommy John elbow surgery, a major blow to the team and the 2020 Cy Young winner.

Bieber, who missed several months last season with elbow issues, experienced pain following an Opening Day start in Oakland and again this week against Seattle. The right-hander underwent imaging tests, and reconstructive surgery on his ulnar collateral ligament was recommended by several doctors.

The recovery time can take up to 16 months following the surgery.
