Australian Open champion Jan Zielinski has hit out at the US Open’s revamped mixed doubles tournament after the initial entry list was revealed this week.

The tournament unveiled the new short-form event, that features nearly every top-10 male and female players.

Men’s No.1 Jannik Sinner has paired with American women’s world No.9 Emma Navarro and men’s No.2 Carlos Alcaraz with former US Open winner Emma Raducanu. Women’s No.1 Aryna Sabalenka has linked up with men’s No.19 Grigor Dimitrov.

Nick Kyrgios has also been tempted by the controversial format, signing up with two-time singles champion Naomi Osaka.

Men’s No.9 Holger Rune and women’s No.2 Coco Gauff are the current top-10 players not to have entered so far, nor have Australian No.1s Alex de Minaur and Daria Kasatkina — the entry window closes on July 28.

Sixteen teams have signed up, with the top eight with the best combined singles ranking guaranteed a place along with eight wildcard entries.

But while all the big stars are seemingly confirmed to play, regular doubles players are set to miss out.

Polish doubles specialist Zielinski, who last year won the Australian Open and Wimbledon with Hsieh Su-wei, was left fuming after not getting an invite.

“I guess winning two grand slams in mixed doubles in one year is not enough to get an invitation to US Open ‘exhibition’ event,” he tweeted.

“Thanks for taking away the opportunity to compete and making it fair to everyone.”

The revamped format was previously criticised by Australian doubles star Ellen Perez and defending champions Sara Errani and Andrea Vavassori, who have entered but will need a wildcard given their singles rankings.

“Tell us that you think doubles players are trash, that tradition is overrated and job opportunity is a thing of the past without actually saying it,” Perez, a players’ council representative, posted on X at the time of announcement.

Errani and Vavassori said the changes were a “profound injustice” that disrespects doubles players, describing the new event as a “pseudo-exhibition focused only on entertainment and show”.

“Making decisions just following the logic of profit is profoundly wrong in some situations,” they added.

The attraction for many singles players is the shortened format and the timing, the event being played in the “Fan Week” before the main draw.

Most matches will be best-of-three sets played to four games instead of six, with a deciding point played at deuce. Tiebreakers would be at 4-4, while a first-to-10-points match tiebreaker would replace a third set.

The final would be played to six games but still with no-advantage scoring and a 10-point match tiebreaker.

This format, the selection criteria and the clash with singles qualifying, are reasons why established doubles players were unhappy.

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