Walston (elbow) paused his rehab program earlier in the season, but he was expected to start building back up around the middle of May, MLB.com reports.
Analysis:
Arizona hasn't provided any concrete information regarding where Walston currently stands in the rehab process, but he's not expected to be a realistic candidate to return from the 60-day injured list until after the All-Star break.
