The Orioles designated minor league reliever Luis Lebron for assignment to open a 40-man roster spot for newly-signed Dylan Bundy, tweets Jeff Zrebiec of the Baltimore Sun. As an advanced high school pitcher, Bundy signed a Major League deal yesterday and therefore required a 40-man spot.
Lebron, 26, missed the 2010 season with Tommy John surgery and returned to action in late July this year. Baseball America ranked him 21st among Orioles prospects prior to the season, as he's a "legitimate power arm out of the bullpen" if healthy.
