Tigers purchased the contract of LHP Jose Alvarez from Triple-A Toledo. Alvarez will make his major league debut on Sunday in place of the injured Anibal Sanchez (shoulder). The left-hander isn't much of a prospect but has been terrific at Toledo this season, posting a 2.42 ERA and 76/15 K/BB ratio over 74 1/3 frames. Sanchez is expected to be OK for his next start, so Alvarez should be sent back down after his debut no matter how he fares.
