The Orioles' legion of former Texas Rangers grew by one Wednesday.
The club claimed 29-year-old side-arming right-hander Darren O'Day from the Rangers and added him to its 40-man roster. O'Day was 0-1 with a 5.40 ERA in 16 games for the American League champs in 2011.
In a four-season career with the Los Angeles Angels, New York Mets and Rangers, the reliever is 8-5 with a 2.89 ERA and has held right-handers to a .214 average in 471 plate appearances.
O'Day will join a bullpen that also includes former players from the Rangers' organization in Pedro Strop, Willie Eyre and Zach Phillips.
The Orioles also announced they reinstated three injured players, pitcher Jake Arrieta, second baseman Brian Roberts and outfielder Luke Scott, to their 40-man roster, which is now at 38.
