O's get Minor Leaguer to complete Bell deal

The Orioles acquired Minor League left-hander Mike Belfiore from the D-backs on Saturday, completing their April 21 trade that saw infielder Josh Bell go from Baltimore to Arizona.

Belfiore, 23, has been assigned to Double-A Bowie. He was the 45th overall pick in the 2009 First-Year Player Draft and has recorded a 2.37 ERA in 19 innings for Class-A Visalia this season, picking up one save with 28 strikeouts and five walks.

Bell, playing with Triple-A Reno in the Pacific Coast League, has posted a .425 batting average and 1.136 OPS with four homers and 27 RBIs in 18 games this season.
