Marlon Byrd and non-roster invitee Kevin Millar are setting the tone in camp for the Cubs.

''I'm a very strong believer in chemistry, and there's nobody better than Lou Piniella when it comes to the chemistry. But this was a tough situation. When you bring a man in, who, hopefully, was going to change, and he's just ... I couldn't understand it, the way he is. He's just not a happy man.''
