Athletics reliever Justin Duchscherer will undergo season-ending surgery on his right hip. An All-Star in 2005, Duchscherer is the latest in a long line of Oakland relievers who have gone down with injuries this season. Duchscherer has been on the DL since May 15 with a right hip strain. The injury did not improve with rest and rehabilitation and Duchscherer was called back from a minor league rehab assignment in late May when the injury flared up.
