Huston Street is taking over the closer role for the Colorado Rockies.
Street, a right-hander acquired as part of a November trade with the Oakland Athletics involving for Matt Holliday, was named Colorado's closer before the Rockies' 7-4 victory over the Arizona Diamondbacks on Thursday.
Street, who lost his closing role to Brad Ziegler with the A's last season, has beaten out Manuel Corpas despite early spring struggles.
Colorado's Troy Tulowitzki was 3 for 3 with two runs scored and a double. Garrett Atkins went 2 for 4 with a double.
Arizona's John Hester was 2 for 2 while Mark Reynolds had a double and Justin Upton had a two-run triple.
