Shi Davidi of Sportsnet.ca reports that the Blue Jays plan to call up prospect right-hander Aaron Sanchez on Tuesday. Sanchez was just shifted to the bullpen last week in Triple-A, which is where he'll pitch in his first taste of the majors. The 22-year-old has posted a 3.95 ERA and 84/57 K/BB ratio over 100 1/3 innings this season between Double- and Triple-A. He still has a promising future as a starter, but the Jays are hoping he can make an impact down the stretch in a relief role.
