Cubs manager Lou Piniella is thinking about taking out Alfonso Soriano is certain situations for defense. Soriano admitted that he lost his concentration chasing a fly ball in left field in Cincinnati on Sunday because he was afraid of crashing into the wall. "You would think that he'll get better," Piniella said on Monday of the left fielder. "That's really the best solution. "He's working. Both balls yesterday, I didn't see, because they got into the corner a little bit. I imagined something was going wrong by the crowd reaction."
