OAKLAND, CALIFORNIA (TICKER) -- The Oakland Athletics on Tuesday placed righthander Justin Duchscherer on the 15-day disabled list with a right hip strain.
The move, retroactive to May 15, leaves the A's with nine players on the DL.
Oakland's primary set-up man, Duchscherer was 3-3 with a 4.96 ERA in 17 appearances this season. The 29-year-old has been on the DL once before in his career, from May 7 to June 23 of last season with right elbow tendinitis.
Duchscherer joins fellow A's pitchers Huston Street (right ulnar nerve irritation), Rich Harden (right shoulder strain) and Esteban Loaiza (muscle spasms) on the DL.
