Puk (elbow) threw a 20-pitch live batting practice session Tuesday, Alex D'Agostino of SI.com reports.
Puk faced hitters for the first time since undergoing internal brace surgery on his left elbow last June. Per Diamondbacks manager Torey Lovullo, Puk's fastball sat in the mid-90s during the throwing session, and the left-hander bounced back well following the workout. The successful live BP session should set Puk up to begin a rehab assignment this weekend in the rookie-level Arizona Complex League.
