The Colorado Rockies' ability to sustain their hot start and contend for the playoffs may depend on whether star shortstop Troy Tulowitzki can stay healthy. Tulowitzki gave the Rockies and their fans a reminder that he has not been the most durable of players over his career when he left Sunday night's game with a strained left shoulder. Troy Renck of the Denver Post reported that Tulowitzki had escaped any serious injury and was only likely to be out 'a day or two', with Tulowitzki himself relieved that it wasn't worse: "Obviously, I was worried when it happened. It kept tightening up," Tulowitzki said after the game. "But I am definitely more confident about it now. Other than losing the game, I am sitting here taking a deep breath and expressing a sigh of relief that I am going to be OK." Tulowitzki sustained the injury to his rotator cuff when sliding into home plate in the first inning. Arizona Diamondbacks catcher Miguel Montero tagged out Tulowitzki easily on the throw from left fielder Jason Kubel, the start to what was a second disappointing night for the Rockies after a loss on Saturday. Although Tulowitzki's shoulder was stiff during and after the game, trainer Keith Dugger confirmed that there was no dislocation and that he didn't think the injury was serious. The Rockies shortstop played only 47 games last season after suffering a groin strain which ultimately required surgery. The last time he played over 150 games was 2009, his age-24 season. If Tulowitzki was to miss an extended period of time, options for the Rockies at shortstop would include Jonathan Herrera, who replaced Tulowitzki in the lineup last night, or current second baseman Josh Rutledge, with the recently-demoted Chris Nelson playing second, where he has started 44 games over the last 3 years. Reid Brignac has also played well over 100 games at short in his career but has only made 1 appearance there so far this season. Follow @mlbinjurynews Looking for fantasy baseball advice?
