Cubs right-hander Mark Prior underwent arthroscopic shoulder surgery Tuesday and will not pitch again this year. An 18-game winner in 2003, Prior has been on the DL once in each of his six big-league seasons but had not had shoulder surgery before. "This is a step in the right direction," said manager Lou Piniella.
"He's 26 years old and obviously has a lot of years to get it right," GM Jim Hendry said of Prior, who didn't make the major league roster out of spring training because of shoulder trouble. Despite over $300 million in off-season spending, the Cubs are in last place in the six-team NL Central.
