Former All-Star closer J.J. Putz will join the Reno Aces to begin a rehabilitation assignment on Thursday.
Jack Macgruder, of Fox Sports Arizona, reports that Putz is also expected to pitch on Saturday, Monday and Tuesday before re-joining the Diamondbacks.
Putz has been on the disabled list since May 8th with a strained ulnar collateral ligament in his right elbow.
He was an All-Star back in 2007, and was named the Rolaids Relief Man of the Year the same season.
Putz has pitched in 14 games this season, making five saves with a 4.26 ERA. He has 188 saves during his 10-year career.
