The Orioles just selected right-handed reliever Adrian Rosario with the fourth overall pick in the Rule 5 draft.
Rosario, 21, was selected off the Milwaukee Brewers' Triple-A Nashville roster. A former non-drafted free agent in 2006, Rosario went 4-0 with a 4.50 ERA in 14 games for Single-A Wisconsin.
The Orioles lost two players in the Major League phase of the Rule 5 draft. The Brewers drafted reliever Pat Egan with the 10th pick in the Rule 5 draft, and the New York Mets tabbed reliever Pedro Beato in the second round of the Rule 5 draft.
Egan went 7-2 with a 3.44 ERA in 49 games between Double-A Bowie and Triple-A Norfolk. Beato was 4-0 with a 2.11 ERA and 16 saves for Double-A Bowie. Beato is a New York native who was originally drafted by the Mets and did not sign.
