Boxberger (abdomen) remains on target for a mid-May return, Bill Chastain of MLB.com reports.
The Rays closer played catch for the second time in his rehab process on Sunday, and is satisfied with his progress to date. "Feeling stronger and stronger every day," he said. "Feeling better each day, so the progression is going well. So we're on target for where we ought to be right now." The 27-year-old may go through a minor-league rehab assignment before returning, but that won't be determined until he's closer to getting back on the field.
