Dominic Thiem, Alexander Zverev and Nick Kyrgios will play exhibition tennis matches in Berlin in July amid the coronavirus pandemic.
One exhibition event will run from July 13-15 on grass and another on a hard court in a hangar in the city’s closed Tempelhof airport from July 17-19.
Each tournament will feature six men and six women and there will be 200,000 euros ($222,000) in total prize money available.
Thiem, Zverev and Kyrgios will be joined by Jannik Sinner for the men’s events. Two more players will be announced later.
Elina Svitolina, Kiki Bertens, Julia Goerges and Andrea Petkovic will be in the women’s events. Two places are still to be confirmed.
Matches will have a super tiebreaker replacing the third set. There will be electronic line calls with no line judges to reduce the number of people involved on court.
The event replaces a WTA tournament in Berlin which was set for June but called off.
