The Orioles today announced that they have acquired minor league left-hander Mike Belfiore from the Arizona Diamondbacks and assigned him to Double-A Bowie to complete the trade that saw infielder Josh Bell go to Arizona. Belfiore, 23, was a first round sandwich selection (45th overall) in the 2009 First Year Player Draft. He pitched to a 2.37 ERA (19.0IP, 5ER), recording one save, striking out 28 and walking five for Class-A Visalia this season.
