The Rockies have claimed right-hander Roansy Contreras off waivers from the Orioles, according to announcements from both clubs. The O’s designated him for assignment last week. The Rockies had an open 40-man spot after they optioned righty Nick Anderson and he exercised his right to elect free agency. Contreras is out of options, so the Rockies will need to open an active roster spot for him once he reports to the team.

More to come.
