Posada asking out of lineup?

I just finished reading Bill Madden's book on the late George Steinbrenner and Buster Olney's book about the Yankees title failures after the 2001 season so my views may be a little influenced by those books. But I can't believe that ANY hitter would ask out of a game against an arch-rival. Seems to me that the most-likely explanation is that one of the Steinbrenner's made the change for the manager and directed that the story be that Posada asked out of the lineup. Interestingly, Posada, Girardi, and Cashman all have different stories on this on GAME NIGHT. (Not much difference than Carney, Obama, and Biden on the Bin Laden strike by the way) Serves the Yankees right that they lost 6-0.
