Maddux said he talks to his brother Greg, a pitcher for the Chicago Cubs, about once a week. "We talk about hitters we have faced. We give each other tips," Mike said. "The only thing we don't discuss is players on our own teams. That would be betraying the trust of our teams." When Greg's name is mentioned to Mike, he sometimes looks strange, and not because he is jealous of his more acclaimed brother. "It's because I don't call him Greg, I call him 'Nate,' a nickname he's always had," Mike said. "Everybody who has known him for a long time calls him 'Nate.' Sometimes I have to remember that I know a Greg Maddux."
