The Orioles designated righty Josh Rupe for assignment to open a 25-man roster spot for shortstop J.J. Hardy, according to the team. Since Hardy was already on the 40-man, the team now has 39 players on that roster.
Rupe, 28, tossed 14 1/3 unimpressive relief innings for the Orioles this year. He signed a minor league deal with Baltimore in December and made the team out of Spring Training. He spent last year relieving for the Royals' Triple-A affiliate, posting a 2.92 ERA, 8.4 K/9, 4.0 BB/9, and 0.9 HR/9 in 52 1/3 innings.
A third-round pick of the White Sox in '02, Rupe was traded to the Rangers in July of '03 along with Frank Francisco and Anthony Webster for Carl Everett. He battled elbow problems in his Rangers career and was designated for assignment in April of '09.
