Awful news for the Rockies at this hour.
Jorge De La Rosa, who left this afternoon’s game against the Diamondbacks in the third inning, was diagnosed with a complete tear of the ulnar collateral ligament in his left elbow. The Rockies are discussing the next step, but odds are he will need Tommy John surgery, which would sideline him until somewhere around the midpoint of the 2012 season.
De La Rosa tested free agency over the winter but re-signed with the Rockies for two years and $21.5 million with a club option for 2013. The 30-year-old southpaw was 5-2 with a 3.51 ERA and 52/22 K/BB ratio over his first 10 starts this season.
Aaron Cook’s pending return softens the blow at least a little bit, but now the Rockies will have to make due without the lone left-hander in their starting rotation.
