Collmenter (shoulder) will start Tuesday for Triple-A Reno, Steve Gilbert of MLB.com reports.

EDGE Analysis

Collmenter has struggled in his last two rehab starts with High-A Visalia as he posted a 12.27 ERA and 10.57 ERA in those outings, respectively. Diamondbacks manager Chip Hale commented that Collmenter "needs to show some positive results" in his upcoming rehab start if he hopes to return to Arizona's 40-man roster. If the 30-year-old can in fact produce a good start for Reno on Tuesday, it might be enough for him to receive a promotion by week's end.
