Carlos Alcaraz will partner British No 1 Emma Raducanu in a blockbuster US Open mixed doubles entry list.
New for 2025, the mixed doubles in New York will be staged in qualifying week on the two biggest courts, Arthur Ashe and Louis Armstrong, over Tuesday 19 August and Wednesday 20 August.
It means that the mixed doubles champions will be decided before even the draw for the singles events are announced.
As well as five-time Grand Slam champion Alcaraz and 2021 US Open champion Raducanu, a host of other top names are competing alongside one another for the $1m champion prize – an increase of $800,000 from 2024.
World No 1 men’s player Jannik Sinner plays alongside American star Emma Navarro, Iga Swiatek will partner Casper Ruud and Nick Kyrgios plays with Naomi Osaka.
Novak Djokovic will play with Serbian compatriot Olga Danilovic, while British No 1 Jack Draper will partner Olympic champion Zheng Qinwen. Tennis power couple Stefanos Tsitsipas and Paula Badosa will also compete together.
The scoring system, until the final, will be sets played to four games with sudden death deuce and a tiebreak at 4-4, with a 10-point tiebreak instead of the third set.
The final will be the same, but with normal six-game sets instead.
Most controversially for tour doubles players, eight pairs have earned entry based on their combined singles ranking, with the other eight pairs have been decided by the US Open’s wildcard committee.

Lew Sherr, the USTA’s CEO and executive director, said: “In our initial discussions about reimagining and elevating the US Open Mixed Doubles Championship, we wanted to find a way to showcase the world’s best men and women competing with and against one another.

“We were confident that we would be able to get the top players in the game excited about this unique opportunity.
“Seeing the teams that have already put their names on the entry list makes us all incredibly excited. It shows that the players are behind what we are trying to do, and we know that the fans will love it.”
