The Arizona Diamondbacks have announced right-handed reliever Brad Bergesen reported to the club on Sunday. Bergesen, 26, spent the first few months of the season with the Baltimore Orioles before being claimed by Arizona on July 20. To make room for their new reliever, the D-backs optioned Bryan Show back to Triple-A Reno.

He had been called up by the Orioles on July 17 from Triple-A Norfolk, where he was 4-3 with a save and 4.03 ERA (36 ER in 80.1 IP) in 22 games (10 starts). In 10 starts, he was 2-3 with a 4.64 ERA (27 ER in 52.1 IP). In 12 relief appearances, he was 2-0 with a save and 2.89 ERA (9 ER in 28.0 IP). In his last 10 relief appearances since June 9, he held opponents scoreless in 6 games for a 2.35 ERA (6 ER in 23.0 IP). Overall, he held righties to a .258 batting average (41-for-159) with 10 walks and 21 strikeouts.

Look for Bergesen to have a role in middle relief with Arizona.
