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.
