With Wimbledon’s main draw starting Monday, a War-of-the-Roses-type power struggle has erupted within the Professional Tennis Players Association, with one group of players and officials suing another group and other executives.

The core allegations include that Winners Alliance, the principal funder of the PTPA since 2023, has milked the players’ group and failed in its economic promises. Meanwhile, what the plaintiffs allege is that an illegal board led by former executive director Ahmad Nassar has taken control of the group illicitly and ousted employees who were investigating his conduct. Nassar is also charged with violating his fiduciary duty to PTPA because of his executive role with Winners Alliance, while PTPA co-founder Vasek Pospisil is charged with taking payments from Winners Alliance that clouded his role with the players group.

The listed plaintiffs in the lawsuit are the PTPA, Saisai Zheng, and Marco Trungelliti. The defendants are Nassar, Pospisil, Bethanie Mattek-Sands, Hubert Hurkacz, Ons Jabeur, Winners Alliance, and Romain Rosenberg. Depending on which side you are speaking with, Rosenberg is either the current executive director (argued by the defendants) or the former executive director who was fired for verbal abuse of a PTPA employee.
