Christian Harrison joins the PTPA’s Executive Committee; Gibson Dunn sports attorney Maurice Suh to advise on governance and structural reform, while athlete representation expert Harry Marino will lead efforts to strengthen player engagement
WASHINGTON D.C., November 3, 2026 – Building on a significant legal victory and its continued efforts to improve professional tennis, the Professional Tennis Players Association (PTPA) today announced that reigning U.S. Open doubles champion Christian Harrison has joined the PTPA’s Executive Committee.
This addition comes as the PTPA enters an important new phase following a ruling by the U.S. District Court for the Southern District of New York allowing the PTPA’s antitrust claims against the ATP, WTA, and organizers of Wimbledon, Roland Garros, and the U.S. Open to move forward.
“I am thrilled to join the PTPA at this exciting moment for the organization and the sport. With the win in court, we have the momentum we need to make lasting change,” said Christian Harrison.
The PTPA also announced two new partnerships focused on organizational reform and player engagement efforts. Maurice Suh, a partner at Gibson Dunn and co-chair of its Sports Law Practice Group, will advise the PTPA and its Executive Committee on organizational governance and structural reform in tennis. He will work alongside colleagues Jeremy Smith and Zach Schreiber, the latter of whom brings experience as a sports agent and in the front offices of two NBA teams.
The PTPA also engaged Harry Marino and Sports Solidarity to expand its outreach and engagement with players. Marino, a former minor league baseball player and president of Sports Solidarity, helped secure minor league baseball’s first CBA with MLB, negotiated the United Football League’s 2025 CBA and led negotiations for the first CBA in American rugby history earlier this year. Sports Solidarity leads organizing and negotiating efforts for athlete associations across several professional sports, including football, rugby, softball, and pickleball.
“Players built the PTPA so we would finally have a say in how our sport is run. The court has confirmed our case goes forward, and we’re bringing in people who have helped athletes in other sports win real change. This gets fixed at the negotiating table or in court. We’re ready for both, and we’ll work with anyone who wants to make tennis better for players,” said Vasek Pospisil, PTPA co-founder and Executive Committee member.
Romain Rosenberg, who joined the PTPA in 2022, has stepped down as Executive Director. During his tenure, he helped guide the organization through the filing of the players’ antitrust case and last month’s court ruling allowing the case to move forward. The PTPA recognizes the contributions Rosenberg made during his tenure.
