Nick Kyrgios teams up with Naomi Osaka, Alcaraz joins Raducanu at US Open

Nick Kyrgios already has a grand slam doubles title to his name and is chasing another with a superstar partner later this year.

Nick Kyrgios has signed up to play mixed doubles with former world No.1 Naomi Osaka in the controversial new format being unveiled at the US Open.

But Kyrgios and Osaka would need a wildcard to get into the event being played in “Fan Week” before the main draw.

The duo were among a raft of interesting pairings who registered, including former US Open winner Emma Raducanu and French Open champ Carlos Alcaraz.

Alex de Minaur and his British fiancee Katie Boulter are also expected to sign up before the July 28 deadline to play the new format, which has so far attracted 16 teams including both world No.1s, Jannik Sinner and Aryna Sabalenka.

Mixed Doubles entry list for the 2025 US Open is (already) out.

It's 'fanfic'-like.

The top eight with the best combined singles ranking will be guaranteed a place along with eight wildcard entries.

Kyrgios, who is ranked 633rd and has hardly played as he continues to battle injury, and Osaka, ranked 57th, would need a wildcard.

Their drawing power, however, could guarantee a spot in the event that rankled traditional doubles players.

“Seeing the teams that have already put their names on the entry list makes us all incredibly excited,” US Tennis Association chief executive Lew Sherr said.

“It shows that the players are behind what we are trying to do, and we know that the fans will love it.”

Tournament organisers have radically changed the mixed-doubles format to involve the world’s best players.

Nine of the world’s top-10 women and nine of the world’s top-10 men are signed up.

The matches will be staged on main courts, including Arthur Ashe, with the scoring system changed.

Sets will only be played to four games, there will be a sudden-death deuce and a tie-break at 4-4, with a 10-point tie-break instead of the third set.

The entire tournament will be played across just two days.

“I’m super excited about it,” Alcaraz said about the prospect of playing mixed doubles with Raducanu.

“US Open came to us and give us opportunities to play mixed doubles.

“I think it’s going to be great. It was an amazing idea for the tournament.

“Yeah, I know Emma since a really long time ago, so we know each other. I have really good relationship with her. She’s going to be the boss.”
