Cubs manager Lou Pinella and starting pitcher Carlos Zambrano insist that nothing is wrong with the right-hander's shoulder, according to The Chicago Tribune. Zambrano admitted that he had a stiff neck while pitching on Saturday, but the pair refuted a report that the team was "keeping a close eye" on his shoulder. "I'm not hurt, I'm not hurt," Zambrano yelled across the clubhouse as reporters converged on his locker. "I feel good. There's nothing wrong with my shoulder."
