Colorado Rockies shortstop Troy Tulowitzki is expected to play in the team’s spring training opener on Saturday. The All-Star was limited to just 47 games last year before groin surgery cost him the rest of the season. He has been working out each day of the spring and ran the bases at full speed on Thursday, showing he was prepared for game action. The Rockies will have a full intersquad scrimmage today before they open the Cactus League schedule Saturday against Arizona.
