The Orioles have three openings in their starting rotation. They're hoping Miguel Castro can fill one of them.
Castro, a cheerful 23-year-old right-hander, was one of the few pleasant surprises on the team's 2017 pitching staff. Acquired from the Colorado Rockies in April, the Orioles had hoped to keep Castro at Double-A Bowie, but after closer Zach Britton was injured and others were ineffective, his arm was needed at the major league level.
In 38 relief appearances, Castro logged 63 innings, fourth-most on the team, trailing only right-handers Mychal Givens, Brad Brach and left-hander Richard Bleier.
Castro compiled a 3.29 ERA in relief and impressed manager Buck Showalter with his endurance and his ability to bounce back quickly.
