Marcus Stroman has a torn ACL and will miss the 2015 season, the Toronto Blue Jays have announced.

Stroman, 23, went 11-6 with a 3.65 ERA last season as a rookie and figured prominently in the team's plans this year.

Alex Anthopoulos said Stroman was participating in bunting practice when he was called off by third baseman Josh Donaldson. Stroman planted his feet to stop, then felt a pop in his knee. An MRI confirmed the tear.
