Manager Chip Hale said that Collmenter (shoulder) could return in early-May, Steve Gilbert of MLB.com reports.

EDGE Analysis

Collmenter has made good progress in his rehab process over the past week and now seems close to returning because of it. Hale said that the right-hander will pitch in games next week, build up his inning count, and then rejoin the Diamondbacks. If everything goes as planned, Collmenter should slot back into the Arizona bullpen as a long reliever, a role that the Diamondbacks desperately need at the moment.
