Rockies' Blair Calvo: Recalled to bullpen

Colorado recalled Calvo from Triple-A Albuquerque on Tuesday.

Calvo holds a rough 8.50 ERA in 18 innings of work this season at the Triple-A level, but the Rockies are desperate for fresh arms. The 27-year-old will presumably operate in a low-leverage relief role as he gets his first taste of MLB action.
