The Orioles have acquired minor league lefty Mike Belfiore from the Diamondbacks to complete the Josh Bell trade, the team announced. Arizona acquired Bell for a player to be named later last month.
Belfiore, 23, was the 45th overall pick of the 2009 draft but has yet to develop as hoped. He owns a 4.05 ERA with 8.5 K/9 and 3.7 BB/9 in 282 1/3 minor league innings, but has experienced some success after moving to the bullpen full-time last year. Baseball America did not rank him among Arizona's top 30 prospects in their 2012 Prospect Handbook.
Belfiore may be best known for throwing 9 2/3 scoreless innings of relief for Boston College during an NCAA postseason game in 2009, the longest game in college baseball history.
