FORT MYERS, Fla. -- Outfield prospect Alex Kirilloff, the Twins' first-round pick in the 2016 Draft, suffered a partial tear of his ulnar collateral ligament and will undergo season-ending Tommy John surgery on March 8.
Kirilloff, who is ranked as Minnesota's No. 3 prospect and No. 98 overall by MLBPipeline.com, suffered the injury on a throw during a game with Rookie-level Elizabethton on Aug. 28, general manager Thad Levine said. Kirilloff spent the offseason rehabbing after getting a platelet-rich plasma injection, but the symptoms returned while trying to throw this spring.
It's a blow to the organization, as Kirilloff will lose a year of development.
