Jenkins was recalled from Triple-A Buffalo on Wednesday, Ben Nicholson-Smith of Sportsnet reports. In 21 games with the big club this season, Jenkins recorded a 2.56 ERA, 1.263 WHIP, and 18:6 K:BB in 31.2 innings. He'll assume middle-relief duty for the Blue Jays, after Sergio Santos was designated for assignment as a corresponding move.
