According to National League sources at the winter meetings here, the Cubs asked the Phillies yesterday what it would take to pry away two-time All-Star rightfielder, Gold Glove winner and reigning Home Run Derby champion Bobby Abreu. The answer: Mark Prior. The Cubs didn't say yes. But they didn't say no, either; at least, they haven't so far. The Cubs did say they would not consider dealing Carlos Zambrano, who is taking his turn atop their pecking order of promising young pitchers, following Kerry Wood and Prior, who is 25.
