Cubs starting pitcher Carlos Zambrano is vowing to stay out of trouble this season. "Yeah," he said when asked by the media if he would behave in 2011. "I want to do more than in the field than what I talk. I don't want to talk this year. I don't want to say anything. I just want to talk with my numbers. That's what I want to do." He guaranteed last spring that he would behave, but the words proved to be worthless. "For real," he said at the time. "I am almost sure- 99.9 percent. When you're sure of something, you go ahead and do it- and execute it. Seriously." Zambrano went bonkers after a first-inning meltdown against the White Sox at U.S. Cellular Field on June 25, leading to a suspension, anger management counseling and a brief demotion to the bullpen.
