All-Star third baseman Scott Rolen will have surgery on his left shoulder and miss the rest of the season, the St. Louis Cardinals said Sunday. Rolen, 30, has a torn labrum and was told he will need at least six months to rehabilitate it after surgery. He is expected to return sometime during spring training. Had he waited on surgery, he could have missed considerable time in 2006. Cardinals team medical consultant Dr. George Paletta will perform the surgery with assistance from Cincinnati Reds medical supervisor Dr. Timothy Kremchek. A date has not been set, but the surgery is expected to take place this week.
