The Colorado Rockies placed All-Star shortstop Troy Tulowitzki on the disabled list Thursday because of a strained left groin. Tulowitzki felt pain after running out of the batter's box when he grounded out to second base during the Rockies' six-run sixth inning against the Houston Astros on Wednesday. He left the game after that, and the Rockies placed him in the 15-day DL on Thursday.
