The Colorado Rockies officially announced on Monday evening that right-handed pitcher Jhoulys Chacin has been placed on the 15-day disabled list with right shoulder inflammation. As a result, the team rescinded the option they used to put him on the Triple-A Colorado Springs Sky Sox' roster. The move is retroactive to Wednesday, May 2, when he was originally sent down.

Chacin had struggled this season, posting a 7.30 ERA in five starts and 24.2 innings. He allowed seven home runs while walking 15 batters to striking out 22 batters. This might help explain some of his struggles this season, but Chacin at times lacked any confidence on the mound.

Alex White and Christian Friedrich will pitch for the Rockies in Chacin's and Jeremy Guthrie's absence.
