Why Milledge Was Left Off the Playoff Roster

Lastings Milledge probably cost himself a playoff roster spot (which instead went to a third catcher) with a "misunderstanding" with a teammate in Atlanta.
Milledge says "It's joking, having fun. Some people took it the wrong way."
But at least one veteran took it more seriously.
Above his locker after Friday's game were two scraps of paper which said
"Know your place, rook! Your teammates."

Randolph ripped the sheets down but not before the media saw them. No one has yet explained the incident.
