Colorado Rockies make multiple roster moves on Friday afternoon in bullpen overhaul

A couple of expected roster moves were made official on Friday before the Colorado Rockies series with the Los Angeles Dodgers: the Rockies have activated Jon Gray from the disabled list, and in turn placed Miguel Castro on the 15-day disable list retroactive to April 18.

Gray has been on the disabled list since the beginning of the season due to an abdominal strain. Castro has had shoulder inflammation that has kept him from pitching since this past Sunday, and will be out for the foreseeable future.

The Rockies have also made four more roster moves that were not as expected as they try to reshape the bullpen after some of their struggles were compounded with Castro's injury. Among them, the club has recalled Carlos Estevez and purchased the contract of Gonzalez Germen from Triple-A Albuquerque.

To make room for the two right-handed relievers, they have optioned Jason Gurka to Triple-A and designated David Hale for assignment, in order to make room for Gonzalez on the 40-man roster.

Combined, these moves will hopefully strengthen a bullpen that has had some struggles while also providing some fresh arms. And above all, Estevez's name should stand out; with Castro injured, the Rockies are obviously intent on giving their hard-throwing young prospect a shot at a big league bullpen gig over the next few weeks.
