The Colorado Rockies placed right-handed pitcher Antonio Senzatela on the 15-day IL with a torn left ACL, the team announced on Friday.
Senzatela was injured during the second inning of Thursday's 13-0 loss to the St. Louis Cardinals while attempting to cover first base on a grounder by St. Louis' Brendan Donovan.
The veteran right-hander fell to the ground near first base and eventually was helped to the Rockies' dugout after a lengthy evaluation.
To fill Senzatela's spot on the roster, the Rockies reinstated right-hander Jhoulys Chacin from the 15-day IL.
