Shoemaker left Saturday's game against the Athletics after three innings with an apparent leg injury, Hazel Mae of Sportsnet reports.

EDGE Analysis

Shoemaker appeared to twist his knee while taking part in a rundown and was in considerable pain. It's a tough break for a pitcher who had been pitching quite well after getting through a run of arm injuries. The nature and severity of this particular problem are not yet clear. Making matters worse, Shoemaker would have been in line for an easy win had he not have had to exit early, with the Blue Jays up way ahead early in a 10-1 win.
