Cubs outfielder Alfonso Soriano will miss at least two weeks of action following arthroscopic surgery on his left knee. Soriano's surgery isn't scheduled, which leaves open the possibility that he might be done for the season. Chicago manager Lou Piniella shut him down on Friday. "Lou said it's not good to play on one leg," Soriano told the Chicago Tribune. "I was 80 percent, but now I'm down to 50 or 60 percent. I play with my knee on my mind, and I'm scared to get hurt. If we're out [of it], it's better to do the surgery before we go to the Dominican [for the off-season]."
