Boxberger (abdomen) will need 4-5 outings on his rehab assignment before he's activated from the 15-day disabled list, Rays beat writer Roger Mooney reports.

An abdominal injury that required surgery has kept Boxberger on the shelf since spring training, but he's been upping his activity of late and he's set to begin his rehab assignment Sunday at High-A Port Charlotte. He told reporters that he'll need at least four outings on that stint before coming off the DL, so a return in the next week or so could be on the horizon.
