The Colorado Rockies have placed ace Ubaldo Jimenez on the 15-day disabled list so he can fully recover from a cracked cuticle on his pitching thumb that threatened to mess up his mechanics.

Jimenez had an awful opener against Arizona last week when he couldn't grip the ball properly and lacked both spin on his breaking pitches and oomph on his usually electric fastball. He gave up six runs on seven hits in six innings.

The move is retroactive to April 2.

The Rockies on Wednesday recalled right-handed pitcher Greg Reynolds from Triple-A Colorado Springs to take Jimenez's roster spot, and he'll pitch Saturday at Pittsburgh.
