The 2012 season is not going at all the way the Colorado Rockies had envisioned it.

Their pitching staff is in shambles, and Wednesday night in Denver, the Rockies' third straight win, giving them a sweep of the Astros, was tempered by news of an injury to star shortstop Troy Tulowitzki. Troy Renck:

Tulowitzki limped through the clubhouse late Wednesday night, favoring the left leg he hurt bursting out of the batter’s box in his last at-bat. He exited the game, and admitted that the injury was much worse than when he first hurt the leg on the second day of the season in Houston turning a doubleplay.

"For me to say that, obviously, it’s a concern," said Tulowitzki, who has lifted his average to .287 with 14 hits in his last 36 at-bats, including four doubles, four home runs and 11 RBIs. "I will see how it feels tomorrow. If it’s still really sore, then maybe I need an MRI and it’s a DL situation. Obviously, I am going to miss a few days at least. I want to stay off the DL. But if I can’t go, I can’t go."

Despite this and other leg injuries this season, Tulowitzki has played in 47 of the Rox' 49 games, hitting a solid .287/.360/.486 with eight home runs and 27 RBI. Renck notes that Chris Nelson is eligible to come off Colorado's disabled list, so he could replace Tulowitzki if the Rockies shortstop has to be sent to the DL.
