Carpenter (back) will take live batting practice Saturday and run the bases Sunday, Evan Petzold of the Detroit Free Press reports.
Carpenter ran the bases at Comerica Park on Thursday and will continue to ramp things back up this weekend. A rehab assignment looks to be close, perhaps with one coming next week if he gets through his activities this weekend with no problems. Carpenter has been sidelined since late May with a lumbar spine stress fracture.
