Surgery to end pitcher Luebke's season

San Diego Padres pitcher Cory Luebke said Monday he will miss the rest of the season after opting to undergo elbow surgery. The Padres left-hander told reporters the reconstructive surgery, to be performed this week, will repair the ulnar collateral ligament of his throwing elbow. The former 2007 first-round draft pick has been on the 15-day disabled list since May 2. Luebke compiled a 3-1 record with a 2.61 ERA over five starts this season before going on the DL. He boasts a 10-12 record with a 3.25 ERA in 55 games during his three-year career with the Padres. Pitcher Matt Palmer joined the team from Class AAA Tucson to take Luebke's roster spot.
