The Colorado Rockies starting rotation has been doing much better than I thought they would this season. Their starters had a 4.00 ERA, 3.92 xFIP, a solid 50 percent ground-ball percentage, a 6.8 K/9 rate and a 3.9 WAR, which was 14th in baseball going into Thurday’s action.
And if you consider they have been doing all this with their ace Ubaldo Jimenez pitching like a shell of what he was last season, their season looks all that more impressive.
The pitcher who has been leading them so far in 2011 has been Jorge de la Rosa.
De la Rosa was 5-2 on the season with a 3.51 ERA, 3.53 xFIP, 7.9 K/9 and a 1.4 WAR. He was pitching better than he did when he won 16 games back in 2009.
Unfortunately for the Rockies, De la Rosa won’t be winning 16 games in 2011. As a matter of fact, he won’t be throwing another pitch for them this season.
According to the Denver Post, De La Rosa will undergo Tommy John surgery to repair a completely torn ulnar collateral ligament in his left elbow. He will miss the rest of the 2011, and like most pitchers who undergo the procedure, he will need the entire year to rehab.
ETA on De la Rosa throwing his next pitch in a Rockies uniform should be in September of 2012.
I think this is a crushing blow for the Rockies. I didn’t think they had enough pitching to get past the San Francisco Giants in the National League West before the season started, and unless the Rockies make a trade for a pitcher, which is something they have been reluctant to do in recent years, I don’t see how that is possible now.
The Rockies are going to need their offense, which has been in the middle of the pack this year and oddly mediocre, to really step up, because I don’t see their starting rotation, even if Aaron Cook does return to health, carrying this team the rest of the way in 2011.
