The Tigers placed Perez on the 10-day injured list Saturday with a left oblique strain.
Perez had to make an early exit from Friday's contest due to what was labeled as abdominal tightness, but further evaluation confirmed the 24-year-old suffered a strain in his oblique. He'll now be sidelined until at least Aug. 20, and Akil Baddoo will come up from Triple-A Toledo to replenish the Tigers' outfield depth.
