The Toronto Blue Jays placed left-hander Patrick Corbin on the 15-day injured list Thursday with a shoulder injury.

Corbin, who turned 37 on Sunday, is dealing with a strain of the left teres major muscle. The two-time All-Star is 3-4 with a 5.51 ERA in 19 games (15 starts) in his first season with Toronto.

Corbin allowed four runs on seven hits in 2 1/3 innings of relief during Tuesday's 12-2 loss to the Tampa Bay Rays.

The Blue Jays also optioned infielder Sean Keys to Triple-A Buffalo and recalled infielder/outfielder Davis Schneider and left-hander Adam Macko from Buffalo.
