Chicago Cubs right-hander Kerry Wood will have season-ending arthroscopic surgery on his right shoulder Wednesday. Wood, who switched to the bullpen Aug. 5 from the rotation to try and alleviate the soreness in his shoulder, was available to pitch Monday night before he is sidelined for the rest of the season. The surgery will be performed by Dr. Timothy Kremchek at Beacon Orthopedics outside of Cincinnati. Wood, the 1998 NL Rookie of the Year, missed the entire 1999 season after Tommy John elbow ligament replacement surgery. He has been bothered by arm problems the last two seasons. Wood is 3-4 with a 4.29 ERA this season. He has started 10 games and made 10 relief appearances.
