Boxberger (abdomen) felt good after throwing Thursday, and his next step is likely a rehab assignment, Steve Carney of 620 WDAE Tampa reports.
Boxberger has made steady progress in his recovery from the abdominal injury he suffered during spring training, and he is on the verge of pitching in a game scenario again. It's not clear how many rehab outings Boxberger will need before he rejoins the Rays, but whenever he does, he is expected to step right into the closer's role currently held by Alex Colome.
