1-ranked Novak Djokovic and former top-30 member Vasek Pospisil would be the co-presidents of a new group they are trying to set up to represent mens professional tennis players. A letter emailed to players -- and obtained by The Associated Press on Friday -- pushes the formation of a Professional Tennis Players Association, abbreviated PTPA. Unlike many other professional sports, mens professional tennis has never had a representative body that is represented for players by players, the email said.
