Diamondbacks' Josh Collmenter: Remains without timetable for rehab

Collementer (shoulder) remains without a timetable for rehabbing his injured shoulder, Jesse Sanchez of MLB.com reports.

Collmenter hasn't pitched since late March, and it appears that he's made no significant progress in his recovery process. This could push his return to the Arizona bullpen to the end of the month or even early-May depending on when he begins his rehab program, but Collmenter's situation should become clearer when he begins rehabbing his shoulder.
