Puk (elbow) will throw a 20-pitch bullpen session before Saturday's game against the Angels, Jordan McPherson of the Miami Herald reports.
Puk continues to work his way back from nerve irritation in his left elbow. If things continues to go well for the southpaw, he could be back as Miami's closer around the start of June, but he also may need a rehab assignment before he's ready to return to action.
