The Cubs expect Carlos Zambrano to be more mature this season. "I expect Carlos to handle himself the way he finished up last year," Cubs manager Mike Quade said. "Whether he explodes or whatever the thing is, all right, so he explodes? Take a walk, see you in five days, pitch well. "If it becomes a reoccurring thing, then we have a problem. If we're going to have individual guys taking care of each guy who has emotional issues, man, we're not going to have a big enough plane." Zambrano went 8-0 in his final 11 starts last season after a blowup in the dugout at midseason. "One thing I don't want to do is take all the passion out of Carlos Zambrano," Quade said. "If a little bit of overexcitement results in him pitching and performing well, we'll deal with that. There's no question Greg Maddux will benefit him and everybody else. But I don't want to make them roommates."
