The new, and controversial, US Open mixed doubles event begins this afternoon with big names from tennis’ list of star players set to headline the tournament. Among them are Carlos Alcaraz, fresh from his win at the Cincinnati Open and British No.

After Emma Navarro's withdrawal, Jannik Sinner will make his US Open mixed doubles debut alongside one of the most decorated doubles player of the last decade. World no. 1 will join forces with Katerina Siniakova.

He chose not to hold a press conference after the Cincinnati Open final but provided some quotes via the ATP, saying that he will be 'ready to push' for another Grand Slam title at the US Open. Sinner also hinted that he would skip the mixed doubles, explaining that he would need a 'couple of days' to get himself back into shape.

Alcaraz won at the French Open and Sinner had struck back at Wimbledon while the decider of the ATP 1000 hard-court tournament in Ohio looked set to be a precursor for this year's US Open. But, due to illness, the World No. 1 was forced to retire after just five games.

Jannik Sinner asked if Serena Williams would come out of retirement to play with him in the US Open mixed doubles, according to Eric Butorac. Sinner, who clinched the Wimbledon singles title in July, is set to play with Katerina Siniakova in the revamped 16-team event at Flushing Meadows.

The highly-anticipated final at the Cincinnati Open came to a sad ending on Monday, as World No. 1 Jannik Sinner was forced to retire from the match against No. 2 Carlos Alcaraz while trailing 5-0 due to illness. With the result, Alcaraz wins his third Masters 1000 title of the season and his eighth overall in his storied young career.

It felt like tennis had delivered the perfect script—world No. 1 Jannik Sinner versus world No. 2 Carlos Alcaraz in a Masters 1000 final. Both had torn through the draw in Cincinnati, barely breaking a sweat, setting up the dream clash fans had been waiting for.
