The Colorado Rockies are suffering through a terrible season. Pitching staff sucks. Defense sucks. The offense isn't as potent as it needs to be. They're just bad.
They lead all of Major League Baseball in screw ups- errors and wild pitches. Giving up that many extra outs and extra bases is not a good thing in that stadium. 96 errors, 69 wild pitches, and 53 unearned runs allowed. Ouch!
