Jake Bloss, one of the top prospects for the Toronto Blue Jays, will undergo surgery to repair the ulnar collateral ligament (UCL) in his right elbow.

The 23-year-old right-hander, ranked as the No. 6 prospect for Toronto by MLB Pipeline, began the season in Triple-A Buffalo, but the 6-foot-3, 223-pound pitcher exited his May 3 start against the Iowa Cubs while holding his right arm. Imaging revealed the extent of the injury.

Bloss posted back-to-back scoreless outings toward the end of April leading up to the injury, a promising turn after he struggled early with 13 earned runs over 11 1/3 innings over the previous three starts.

Toronto manager John Schneider said Tuesday that he was unsure if Bloss will need full Tommy John surgery.

Bloss, a 2023 third-round draft pick, was acquired last year from the Houston Astros, for whom Bloss made three appearances in 2024. He went 0-1 with a 6.94 ERA and 11 strikeouts in 11 2/3 innings.
