The Orioles have announced via a press release they have designated left-hander Mike Belfiore for assignment. The move, along with placing right-hander Edgmer Escalona on the 60-day disabled list, clears roster space for the addition of outfielder Delmon Young and right-hander Evan Meek to the 40-man roster.
Belfiore made his MLB debut last September for the Orioles throwing 1 1/3 innings against the Red Sox allowing three hits, including a pair of home runs. At Triple-A, the 25-year-old made 37 relief outings posting a 3.18 ERA, 9.7 K/9, and 3.4 BB/9. The Diamondbacks made Belfiore the 45th overall pick in the 2009 amateur draft, but shipped him to Baltimore in 2012 as the player to be named later when they acquired Josh Bell.
