Toronto Blue Jays right-hander Marcus Stroman suffered a torn ACL that will sideline him for the 2015 season.
Stroman was injured during a drill at spring training when he was fielding a bunt and heard a pop in his left knee.
The 23-year-old was coming off an impressive debut season in the major leagues. Stroman posted an 11-6 record with one save and a 3.67 ERA in 26 games and 20 starts covering 130 2/3 innings in 2014. His walks-to-strikeouts ratio was an impressive 28/111.
With Stroman out of the rotation, the Blue Jays are expected to turn to Marco Estrada, Daniel Norris and Aaron Sanchez to compete for the opening.
