The new, and controversial, US Open mixed doubles event is underway with big names and star players set to headline the tournament.
Among them are Carlos Alcaraz, fresh from his win at the Cincinnati Open, and British No. 1 Emma Raducanu, who will partner each other over the two days of the competition. The top-seeded pair features British No 1 Jack Draper alongside Jessica Pegula, who face Alcaraz and Raducanu in the round-of-16.
The new-look mixed doubles in New York will be staged on the two biggest courts – Arthur Ashe and Louis Armstrong – over Tuesday 19 August and Wednesday 20 August with the $1m on offer for the champion prize. The revamped format, and its disregard for doubles specialists, has proved controversial, however.
Jannik Sinner has withdrawn from the event, as he had been expected to after the World No. 1 pulled out of the Cincinnati final through illness partway through the opening set with Alcaraz leading 5-0. Sinner is fully focused on recovering in time for the US Open singles.

Swiatek/Ruud into semi-finals
19:37 , Flo CliffordAnd over on Arthur Ashe, Swiatek and Ruud have made light work of McNally and Musetti, winning 4-1 4-2.
With these two quarter-finals over, it’s almost time for the Battle of the Brits: Jack Draper and partner Jessica Pegula will play Carlos Alcaraz and Emma Raducanu next.
Errani/Vavassori move one step closer to defending their crown
19:34 , Flo CliffordVavassori’s reflexes are just stunning as he recovers from a Rublev body serve, firing away at the net to retrieve one point of the deficit. The pair share a nice hug at the net.
Now the Italian pair roar as they nullify the mini-break entirely, Errani’s deft touch coaxing an error from Rublev, who fires long for 4-4.
“Forza” shouts Errani as she lobs to lead 5-4. Vavassori has two serves... their opponents send it long to hand the Italians match point.
Rublev goes long again and the Italians are into the semi-finals! The pair bump heads and scream with delight. It means an enormous amount to these two. 4-1, 5-4.
Tie-break to decide second set
19:30 , Flo CliffordErrani holds to send this one to a tie-break. Over on Arthur Ashe, Swiatek/Ruud lead 3-2 in another close second set.
And it’s Muchova and Rublev who get an early mini-break, the Czech lobbing the ball over the head of Vavassori.
An error from the Italian sees them fall 3-1 behind, and Muchova blasts a cross-court forehand which skims past Rublev, stunning her partner! He grins and gestures as if to say it nearly took his ear off.
They lead 4-2 at the change of ends.
Crunch time on Louis Armstrong
19:24 , Flo CliffordThe crowd goes wild! Muchova and Rublev dig very, very deep in the Czech’s service game over on Louis Armstrong, withstanding a barrage at the net to dink the ball over the net and seal the deciding point for 4-3. The pair look very relieved and celebrate passionately.
VA-VA-VOOM 💥

On serve in second set
19:14 , Flo CliffordA spirited Muchova volley lands splat in the middle of the court and we remain on serve in this one, with the Czech and Rublev leading 3-2.
Swiatek/Ruud and McNally/Musetti are locked at 1-1 in the second as both matches prove more competitive.
Specialists on top
19:03 , Flo CliffordErrani and Vavassori duly take the first set 4-1, as do Swiatek and Ruud by the same scoreline. Both teams are speeding through this one; Vavassori holds to 15 with a quick service game for 1-1 in the second set.
Italians motoring through
18:53 , Flo CliffordAfter going down an early break Errani and Vavassori are well in control of this one, leading 3-1 as they break the Muchova serve.
Over in the other quarter-final, Swiatek and Ruud lead McNally and Musetti 2-1.
Errani/Vavassori lead
18:48 , Flo CliffordErrani and Vavassori respond by immediately breaking back, breaking the Rublev serve. They clearly mean business.
The Czech/Russian pair trouble them a little on Errani’s serve, but a Rublev error puts the fired-up Italians in front, 2-1 up.
Quarter-finals underway
18:41 , Flo CliffordAnd after about ten minutes, it’s time for the first of today’s quarter-finals. Muchova and Rublev take on Errani and Vavassori.
And it’s Muchova and Rublev who strike first, breaking the Vavassori serve!
Swiatek/Ruud beat Tiafoe/Keys
18:30 , Flo CliffordVery efficient from third seeds Casper Ruud and Iga Swiatek, who beat another all-American pair in Frances Tiafoe and Madison Keys. 4-2, 4-1 in 39 minutes. Formats may change, but Swiatek scorelines stay the same.
It’s the Pole who seals the deal with a fine stroke than dips just inside the baseline. They’ll face Caty McNally/Lorenzo Musetti in just a few minutes.
“She’s on a winning train these days and I’m just jumping on the train,” Ruud says of his partner. Both add that having played against each other in the United Cup, they had an idea of how they would work as a pairing, despite the lack of preparation time.
What a way to finish!

Rublev/Muchova to play Errani/Vavassori
18:25 , Flo Clifford“We came out here to have fun, Reilly his serves - I think we made one return, maybe two!” Muchova says.
“Karolina did unbelievable things,” Rublev says of his partner’s performance, “I don’t know how many players from men’s tour can do this. I have no idea what I’m doing when I’m playing but I’m trying to do my job!” the Russian adds.
The pair will return to action in only a few minutes to take on a daunting task: Sara Errani and Andrea Vavassori.
Rublev/Muchova seal place in second round
18:18 , Flo CliffordMuchova steals a rare point off the Opelka serve as she forces Williams into a net error, and Rublev looks amazed.
He thinks he’s won the match with a brilliant serve-and-smash combo, but will play at least one more point! Laughs all round.
Match point... Opelka nets a second serve, and the Americans are out! 4-2, 5-4(7-4).
Muchova/Rublev on top
18:14 , Flo CliffordScreams of delight from the crowd as Muchova/Rublev and Williams/Opelka get into a tense, tight, net exchange, with the Czech forcing an error from Williams to lead 2-1 in this tiebreak.
Rublev bows down in appreciation of his partner’s brilliance, before blasting a return at Williams, forcing another error for an early mini-break.
The Americans pull one back but Muchova plays a stunningly deft low volley, with Rublev slamming away a smash to lead 4-2.
Tie-break!
18:09 , Flo CliffordMuchova holds serve to 15 for 4-4 and a seven-point tiebreak will be played to settle this set.
Timeless.

Ruud fires third seeds to first set
18:02 , Flo CliffordIga Swiatek certainly doesn’t look hampered by her less than 24 hour turnaround from winning Cincinnati to playing in New York. She and Casper Ruud take the first set 4-1 against Madison Keys and Frances Tiafoe, the Norwegian firing down an ace to seal it.
In the other match, Williams hits long and Rublev/Muchova level things at 3-3 in the second set. First to five games now, but if it goes to 4-4, there will be a tiebreak.
On serve in second set
17:52 , Flo CliffordOpelka and Williams dig themselves out of trouble in the second set, winning a deciding point - to raucous applause from the partisan crowd - to move 2-1 ahead, on serve.
Over on Arthur Ashe, third seeds Iga Swiatek and Casper Ruud are an early break up against Madison Keys and Frances Tiafoe.
Rublev and Muchova seal first set
17:40 , Flo CliffordOohs and ahhs from the crowd as Rublev and Muchova produce some delightful tennis to take the first set 4-2. This makeshift pair has combined well so far, with Muchova’s net ability and craftiness complementing the ferocity of Rublev’s groundstrokes. A tidy volley from the Russian seals the set.
Muchova/Rublev lead Williams/Opelka
17:35 , Flo CliffordOver on Louis Armstrong, Karolina Muchova’s guile has put her and Andrey Rublev against 45-year-old Venus Williams and her partner Reilly Opelka - a man who has notably poured scorn on doubles in the past.
The big American batters down some aces, finishing with a second-serve ace, to keep their deficit to just one break at 3-2.
GAME, SET AND MATCH! McNally/Musetti 5-3 4-2 Osaka/Monfils
17:24 , Jamie BraidwoodWe have our second winners of the day! And it’s a eye-catching partnership between Caty McNally, a two-time grand slam doubles finalist, and Lorenzo Musetti that prevails over Naomi Osaka and Gael Monfils, who are smiling and laughing as they leave the court.
Certainly, McNally and Musetti look to be a serious doubles partnership, despite only meeting a few days ago, with some potential to go the distance. I don’t think Osaka and Monfils are too concerned to be out already as they take a selfie before leaving the court.
McNally and Musett go up against either Iga Swiatek and Casper Ruud or Madison Keys and Frances Tiafoe next.

Andrea Vavassori: 'We were playing for the doubles teams who could not be here'
17:03 , Jamie BraidwoodWell, Andrea Vavassori basically just confirmed what I was wondering in the last post.
The Italian says during his post-match interview: “We were playing for the doubles teams who could not be here.”
I think they could take some stopping, despite the star power of some of the singles players in the draw.
They will take on either Venus Williams and Reilly Opelka or Karolina Muchova and Andrey Rublev, who are up next.
Venus Williams is obviously a huge draw as she returns to the US Open at the age of 45.
GAME, SET AND MATCH! Errani/Vavassori 4-2 4-2 Rybakina/Fritz
16:56 , Jamie BraidwoodThe defending champions go marching on! A big win for the Italian doubles partners Sara Errani and Andrea Vavassori, who dump out Taylor Fritz and Elena Rybakina. They were certainly playing with some heat, and one suspects they were playing for all the doubles players who have been excluded form this revamped competition.
They were excellent, and fly through to the quarter-finals in just over 40 minutes. Huge celebrations and a butt of the heads between the pair as Vavassori lands a smash. 4-2 4-2.
Statement made 👊

Errani and Vavassori move one game away
16:53 , Jamie BraidwoodStirring stuff from Errani and Vavassori as they bring up three break points with a brilliantly constructed points against the Fritz serve. The American saves three in a row behind serve, with two aces, but Rybakina then frames a volley at the net!
Errani and Vavassori will serve for the match next, with Vavassori to serve.
FIRST SET! Errani and Vavassori strike first!
16:34 , Jamie BraidwoodWe have our first completed set in the US Open mixed doubles - a reminder that the format is best-of-three sets to four games - and it goes the way of the defending champions Sara Errani and Andrea Vavassori. The Italian pair convert the only break to lead Taylor Fritz and Elena Rybakina, the scoreline 4-2 in the first set.
The defending champions and doubles specialist are playing with a point to prove.
Coming out swinging 🔥

US Open mixed doubles
16:28 , Jamie BraidwoodBrilliant early point in the Musetti/McNally vs Monfils/Osaka match! Osaka first with the big forehand down the line, defended well by Musetti at the back of the court. Eventually, Monfils was able to put the overhead away.
US Open mixed doubles
16:25 , Jamie BraidwoodSome interesting observations from the match of Arthur Ashe early on, including Italy’s Lorenzo Musetti serving faster balls at Gael Monfils than Naomi Osaka. The Olympic bronze medalist took almost 50mph off his serve when serving to Osaka.
And the doubles specialist in this match, Caty McNally, is being the most decisive player at the net. A few misses so far from the American, but the movement and sense of where to be in position is clearly way ahead of the other three, who are far more accustomed to singles.
An update from Jannik Sinner after pulling out of US Open mixed doubles
16:12 , Jamie BraidwoodA post from Jannik Sinner confirming that he is looking forward to resting “for a couple of days” after pulling out of the US Open mixed doubles before “getting back to work”.
Yesterday I didn’t feel great and I’m really sorry to disappoint you. Thank you so much to everyone supporting me on-site and from home, your support means the world ❤️ Congrats to @carlosalcaraz and his team, you’re having an incredible season and I wish you all the best for… pic.twitter.com/hBxvHixEsH

Players on court ahead of start of US Open mixed doubles
16:08 , Jamie BraidwoodTo be fair, for all the critics that the new US Open mixed double event has had, there are plenty of fans in the Arthur Ashe Arena for the start of play. Perhaps a lot of fans who wouldn’t get the chance to take in the US Open during the fortnight, too.
It’s not sold-out, are there are some more empty seats on Louis Armstrong, but a decent turnout.
US Open mixed doubles getting underway soon
15:57 , Jamie BraidwoodSo the first couple of matches of the new-look US Open mixed doubles are about to begin. On Arthur Ashe, we have former US Open singles champion Naomi Osaka partnering the entertaining and ever popular Gael Monfils, who stepped in to replace Nick Kyrgios. They are in action against Caty McNally and Lorenzo Musetti.
But the match to look out for is the one involving the doubles specialists and defending US Open mixed champions, Sara Errani and Andrea Vavassori, who are up against singles players in Taylor Fritz and Elena Rybakina.
Errani and Vavassori were very outspoken in their criticism of the new event - so this is something of a grudge match for them.
Matches coming up:
Naomi Osaka/Gael Monfils vs Caty McNally/Lorenzo Musetti
Sara Errani/Andrea Vavassori vs Elena Rybakina/Taylor Fritz (2)
All-American pair replace Sinner and Siniakova
15:46 , Flo CliffordSinner and Siniakova’s place in the mixed doubles draw has been confirmed in double-quick time: the all-American pair of Danielle Collins, a former top-10 player, and the 17th-ranked men’s doubles player Christian Harrison have taken their spot.
Full US Open mixed doubles draw
15:43 , Flo CliffordJannik Sinner’s withdrawal means a different team entirely will play Belinda Bencic and Alexander Zverev later today.
British No 1 Jack Draper and Jessica Pegula are the top seeds in New York, anchoring the top half of the draw, with former Wimbledon champion Elena Rybakina and last year’s US Open singles semi-finalist Taylor Fritz the second seeds, in the opposite half.
Fresh from her triumph in Cincinnati, Iga Swiatek is still set to play this week and partners Casper Ruud; the pair are the third seeds. Amanda Anismova and Holger Rune completed the seeded pairings.

Jannik Sinner drops big clue around potential involvement in US Open mixed doubles
13:15 , Jamie BraidwoodJannik 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 arrives in New York ahead of US Open mixed doubles
12:55 , Jamie BraidwoodNovak 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.

“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.”

What happened in the Cincinnati Open final?
12:15 , Jamie Braidwood- 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

US Open mixed doubles champions lead criticism of revamped event
10:55 , Jamie BraidwoodLast year’s US Open mixed doubles champions Sara Errani and Andrea Vavassori labelled the revamped competition as a "profound injustice" following the announcement of the new format in February.
Errani went further in an interview with the Associated Press before the tournament, calling the changes to the mixed doubles event “nonsense” and “sad”.
Errani and Vavassori will start to defend their title when they take on Taylor Fritz and Elena Rybakina, two singles stars, in their first-round match later this afternoon.
Errani argued: "It would be like if, at the Olympics, they didn't let the actual high jumpers participate, and instead had basketball players compete in the high jump because it's more 'interesting.'
"You can't have a Grand Slam doubles (trophy) and not let doubles players take part. ... You're excluding them from their sport. It's dishonest."
