Cubs pitcher Carlos Zambrano has apologized for his dugout tirade last month and says he wants to remain in Chicago. Zambrano has been on the restricted list since June 29 following a three-game suspension for an emotional outburst aimed at teammates. "It was a moment of frustration," Zambrano said Monday in an interview with ESPN. "I was trying to fire up the team. [Derrek] Lee told me to shut up, and I got more excited. I apologize from the bottom of my heart. The last person I would be mad at is D. Lee; he's a Gold Glover. I was just mad at myself." Zambrano said he has already apologized to Lee. "I texted Lee two days after it happened, and we talked after that," Zambrano said. "I apologized to him, and he responded well. He's a professional. He's one of the best teammates you can have." Zambrano will return to the Cubs on Friday in Denver.
