MESA, Ariz. -- D-backs right-hander Josh Collmenter reported tightness in his right shoulder after his appearance Sunday, and it is possible he could open the year on the 15-day disabled list.
"He didn't feel like he could get the extension he needed," Arizona manager Chip Hale said of Collmenter. "We shut him down for a couple of days. I think he's back throwing now. Is he going to start the season on the DL here? That's a decision we have to make here with him."
Hale said tests done on Collmenter's shoulder did not show damage, but rather just inflammation.
