Jannik Sinner’s preparations for the US Open ended in emotional scenes as he retired from the Cincinnati final after just five games and 23 minutes.

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.

Alcaraz snapped the world number one's 26-match winning streak on hardcourts when Sinner signalled he could no longer continue while trailing 5-0 in the first set of the Cincinnati final

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.

Well, well, well. Just when you thought the tennis world couldn’t get any more chaotic, Jannik Sinner finds himself scrambling for a new mixed doubles partner at the eleventh hour.

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.

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.

The draw for the men’s and women’s singles will take place on Thursday 21 August. The start time of the draw has yet to have been confirmed but the ceremony usually takes place at around 5pm BST. It will be available to watch live on the US Open website.
