The Orioles have designated Brad Bergesen for assignment, reports Dan Connolly of The Baltimore Sun (on Twitter). The move clears a 40-man roster spot for Bill Hall, who was called up from Triple-A.
Bergesen, 26, had pitched to a 5.13 ERA with 4.6 K/9 and 3.5 BB/9 for the team's Triple-A affiliate this season. He's made 59 starts and 24 relief appearances for the Orioles over the last three seasons and owns a 4.68 ERA in 394 1/3 career innings. Bergesen appears to be a candidate for a waiver claim given his age, flexibility, and the fact that he has a minor league option remaining.
