The Orioles have acquired right-hander Miguel Castro off waivers from the Rockies for a player to be named later or cash, per a team announcement.
Castro, 22, is a 6-foot-5, 190 lb. righty who was designated for assignment by the Rockies after not making the club out of spring training. He has an option remaining, meaning the Orioles can stash him at Triple-A Norfolk as bullpen depth this season.
Colorado employed Castro in the major-league bullpen in each of the last two seasons, but he struggled to a 7.20 ERA mark in 20 innings of work. The Dominican righty struggled mightily at Triple-A last year for Colorado (10.34 ERA in 15.2 innings).
Castro is perhaps best known for his inclusion in the 2015 blockbuster trade that sent Troy Tulowitzki to the Blue Jays, heading to Colorado along with Jose Reyes, top prospect Jeff Hoffman and Jesus Tinoco. He was considered a top prospect at that time due to his big arm and minor-league success from 2012 to 2015.
