US Open 2025 live: Jannik Sinner injury update ahead of Raducanu-Alcaraz in controversial new mixed doubles event

After his withdrawal with illness from Monday’s Cincinnati Open final against Carlos Alcaraz, it looks likely that world No 1 Jannik Sinner will withdraw from the mixed doubles event.

He had been slated to team up with 10-time women’s doubles major champion Katerina Siniakova, but the US Open official draw page now has a blank pairing where the two should be, against Belinda Bencic and Alexander Zverev.

The US Open official X account has also just posted a cryptic statement: “Find your partner, we’re mixing it up today”.

Sixteen pairs will compete in the event, resulting in four rounds of competition.

The scoring system, until the final, will be best-of-three sets played to four games with sudden death deuce and a tie-break at 4-4, with a 10-point tiebreak instead of the third set if necessary.

The final will be the same, but with normal six-game sets instead.

The mixed doubles event takes place on Tuesday 19 August and Wednesday 20 August on the two biggest show courts at Flushing Meadows, Arthur Ashe and Louis Armstrong.

Matches start at 11am local time, that’s 4pm BST. Alcaraz and Raducanu’s match against Draper and Pegula is scheduled third on Arthur Ashe on Tuesday, around 2pm local time – 7pm BST.

Jannik Sinner did not hold a press conference after last night’s Cincinnati Open final, but he did provide some quotes that were released by the ATP.

He was not specifically asked whether he would skip the US Open mixed doubles after pulling out of the Cincinnati Open final with illness, but the 24-year-old did say that he now has “a couple of days of recovery” before the start of his US Open singles defence latest this week.

“I love Grand Slams a lot. This is the main, main tournaments for my season and for my career,” Sinner said.

“So US Open is going to be tough tournament, but in the same time, I’m looking forward to it. If I’m ready, physically and mentally, I will be ready to push.

“So as I said, now a couple of days of recovery, and then we get again back to work, and hopefully we’ll be ready. So for sure, the main goal here in the US.”

Novak Djokovic arrived in New York on Monday evening ahead of his latest bid at winning his 25th grand slam singles title.

First, the 38-year-old will partner Serbian compatriot Olga Danilovic in today’s revamped US Open mixed doubles.

They will take on the Russian pair of Mirra Andreeva and Daniil Medvedev, who Djokovic defeated to win the 2023 US Open final.

That was his last grand slam title, with the next seven won by either Carlos Alcaraz or Jannik Sinner.

“Usually I start with the opponent but today I have to start with you guys [the crowd]. I’m super super sorry to disappoint you. From yesterday I didn’t feel great. I thought I would improve during the night. It came up worse.

“I tried to come out and make it at least a small match but I couldn’t handle more. I’m very very sorry for all of you. I know some of you on Monday maybe had to work or do something else, so I’m very very sorry.

“Of course Carlos congrats. Another title. Not the way you wanted to win but it’s amazing what kind of season you’re producing. You and your whole team are doing amazing. Keep it up. I wish you only all the best for the U.S. Open and the rest of the season.”

• There was a lot of anticipation ahead of the final between Carlos Alcaraz and Jannik Sinner after their clashes in the finals of the French Open and Wimbledon this summer
• But Sinner looked out of sorts from the start on what was a hot afternoon in Ohio, with the final starting at 3pm local time under intense sun
• Alcaraz raced into an early lead, breaking Sinner’s serve twice as the World No 1 struggled with his movement and the timing of his groundstrokes
• After losing his serve for the third time, and trailing Alcaraz 5-0 in the first set, Sinner called the trainer and then retired from the match, saying he was “sorry for the fans”.
• Sinner confirmed during the trophy ceremony that he had started feeling ill the day before, with his condition worsening on the day of the final
• The Italian is now a major doubt to play in the new-look US Open mixed doubles tournament, which begins later, but he should be fine to start his US Open title defence later this week
