EDGE Analysis

EDGE Analysis

Puk has spent the entire season working his way back from an internal brace procedure he received last June and was cleared to begin a rehab assignment in late May.

An updated timeline for his return will likely be available once his test results come back.

Puk (elbow) allowed one hit and struck out one over a scoreless inning in a rehab appearance for Triple-A Reno on Tuesday.

EDGE Analysis

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.

EDGE Analysis

It will be the first time he's faced hitters since he had an internal brace procedure on his left elbow last June.
