Andrew Puk: Everything you need to know

Diamondbacks general manager Mike Hazen said Monday that Puk (elbow) will need 7-to-8 rehab appearances before returning from the 60-day injured list, Nick Piecoro of The Arizona Republic reports. Puk began his rehab assignment with the team's Arizona Complex League affiliate on Saturday, striking out one over a perfect inning. The left-hander will move up to a higher affiliate and make several more rehab appearances before rejoining the Diamondbacks' bullpen.

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.

Puk (elbow) will throw a live batting practice session Tuesday, Alex Weiner of ArizonaSports.com reports. It will be the first time he's faced hitters since he had an internal brace procedure on his left elbow last June. If things go well for Puk on Tuesday, he could appear in an Arizona Complex League game Saturday. Puk should be ready to rejoin the Diamondbacks' bullpen sometime in June as long as he doesn't encounter any setbacks.
