Chicago Cubs pitcher Kerry Wood has decided to undergo surgery on his troublesome right shoulder, the team announced Monday, which will signal the end of the oft-injured right-hander's season. Wood, who has spent two separate stints on the disabled list this year, will have the procedure Wednesday at Beacon Orthopedics in Sharonville, Ohio. Cincinnati Reds team physician Dr. Timothy Kremchek will perform the operation. The 1998 National League Rookie of the Year was first placed on the DL in early May with a strained shoulder and was shelved until the end of June. He made five starts upon returning but was put back on the DL after leaving a July 20th loss to the Reds after three innings. Wood returned to action on August 5 and pitched strictly out of the bullpen for the first time in his career in an attempt to ease the burden on his shoulder. Wood performed well as a reliever, recording a 2.45 earned run average in 10 appearances, and will still be available to pitch out of the pen in Monday's game against the Dodgers. The 28-year-old has thrown just 65 innings over 20 outings, including 10 starts, this season and is 3-4 with a 4.29 ERA -- his highest since 2000. The Cubs expect Wood to be at full strength in time for spring training and is slated to return to the starting rotation in 2006.
