The Rockies will be without shortstop Troy Tulowitzki for at least six weeks after he broke his left wrist. Tulowitzki was hurt when he was hit by a pitch from Twins reliever Alex Burnett in the eighth inning of a win Thursday in Minnesota. While the initial examination didn't reveal a break, an MRI on Friday found an avulsion fracture, where a fragment of bone tears away. Tulowitzki was placed on the 15-day DL Friday afternoon and the Rockies recalled Chris Nelson from Colorado Springs to fill his roster spot, according to an ESPN.com report.
