A win and two losses for the Rockies

Colorado topped Arizona, 12-4, in day portion of a day-night and then dragged themselves out to lose the nightcap, 5-2, after finding out that Jorge de la Rosa has been lost for the next year with a torn elbow ligament. The team said an MRI showed a complete tear of the ulnar collateral ligament in De La Rosa’s left (pitching) elbow, and manager Jim Tracy said he’ll undergo Tommy John-style tendon replacement surgery.

De La Rosa was the Rockies’ top pitcher so far with a 5-2 record and a 3.51 ERA. He was coming off his first career complete game when he got hurt. De La Rosa missed 13 starts in 2010 and the team finished 4-9 in those games.

During the opener, a 27-year-old man was critically injured when he fell from a stairwell leading to the center field seats at Coors Field. The man was hospitalized in critical condition following a fall of approximately 20 feet onto concrete.
