Cubs first baseman Derrek Lee has heard his name mentioned in trade rumors, but he isn't concerning himself with them. "I think it happens with every team," Lee said. "When you're not playing well trade rumors pop up. When you turn it around and play well, you won't hear them. It's just part of the business." The Cubs have denied they've talked with the Angels about Lee, as was reported Thursday in the Chicago Tribune. "Who are the 'excellent sources?'" Lee asked. "I've heard nothing on it. I've got nothing for you."
