Bundy received a platelet-rich plasma injection about six weeks ago and has been throwing without setbacks for about a week.
Top position player prospect Jonathan Schoop (lower back stress fracture) took the next step in his recovery. He's jogging in a pool and throwing.
Schoop was prescribed rest when he was reevaluated near the end of May by a doctor in California, who confirmed the original diagnosis of a stress fracture in his lower back. Manager Buck Showalter said at that time Schoop could be playing in the first or second week of July.
