Puk (elbow) allowed one hit and struck out one over a scoreless inning in a rehab appearance for Triple-A Reno on Tuesday.
The Diamondbacks moved Puk's rehab assignment to Reno after the left-hander threw three scoreless innings in three appearances in the rookie-level Arizona Complex League to close out May. He's scheduled to throw again Friday, per Alex Weiner of ArizonaSports.com, and Puk will likely need a few more appearances beyond this week before being activated from the 60-day injured list. When Puk opened his minor-league assignment last month, Arizona general manager Mike Hazen said the team was targeting him seven or eight rehab outings, which puts the reliever on a path to return from the shelf around the middle of June.
