Cubs outfielder Alfonso Soriano wants to have surgery "sooner than later," which should end his season. "I'm very disappointed, but I have to do what I have to do," Soriano told ESPN 1000's Bryan Dolgin. "I'm battling. Now I think I want to get an operation sooner than later ... to get ready for next year. I have to play with one leg now." Soriano has played in just two games since Aug. 29. "He's going to see his own doctor, I think to get a second opinion, and we'll probably know something the next few days," Cubs manager Lou Piniella said. "I would categorize it as doubtful that he'll return. "I would think if he has a procedure before the end of the year, it would be to clean it out."
