Omar Minaya has seemed willing to trade the rookie outfielder Lastings Milledge in the past, and based on recent events in the clubhouse, he may be more willing to use him as the prime trading chip to acquire an ace. A handwritten sign hung above Milledge?s locker after Friday?s game. It read: ?Know Your Place Rook!? It was signed: ?Your Teammates.? Manager Willie Randolph brushed it off as typical rookie hazing, but Milledge, who was clearly distraught, has alienated a few veteran players with his cocky attitude and what is perceived as a lack of professionalism.
