We will, of course, be back for more tomorrow. Bye!In the doubles, there have been wins for Britain’s Arthur Fery and Jonathan Paris, the British-American duo Neal Skupski and Christian Harrison, who won the Australian Open title this year, and also the top seeds in the women’s event, Taylor Towsend and Katerina Siniakova, the runners-up in 2025.Michael Zheng’s fans are, unsurprisingly, out in force on Grandstand, cheering on the Columbia University graduate, and they’re screaming “LET’S GO MICHAEL” when the 22-year-old moves to set point at 6-5 in the first-set tie-break. Even though he can’t take it, his supporters are in full voice as the pair change ends at 6-6 … and now Arthur Gea has his second set point. Gea biffs a backhand wide, but soon gets a third SP .. and he takes the breaker 9-7 with a stinging forehand winner down the line, leaping into the air in celebration. Zheng’s fans still aren’t silenced.Khachanov beats Bonzi; Sweeny's run endsThe results keep on coming: the resurgent Russian Karen Khachanov, the former semi-finalist, is playing like it’s 2022 again, having backed up his win over Felix Auger-Aliassime with a 6-3, 6-2, 6-4 victory over France’s Benjamin Bonzi. And Australian hopes in the singles are over, with Dane Sweeny unable to follow up his success against Lorenzo Musetti, losing 6-4, 6-3, 6-3 to Luciano Darderi. Khachanov will meet the winner of Learner Tien v Jakub Mensik in the last 16, while Darderi will play Alexander Zverev or Alejandro Tabilo. Both those matches take place in the night session.So – Gauff is asked about her ability to adapt how she plays during matches. “It’s all about how I’m feeling, if I feel good I’ll play offensive,” she replies. “When I feel I’m not playing the ball well I play defensive. In the first set today it was defensive. Once I got into my rhythm, I could hit through more. I had to sacrifice some points to get going again.”On reaching the second week, she says: “I feel like I’m used to getting to the second week now. I woke up today and I was like: ‘Oh we’re already in round three.’ I’m enjoying the experience, there’s expectations being American and I want to do well in front of the fans. Last year I put too much pressure on myself.”“It was way different playing in the day session than the night, but I was happy with the way I fought through, even when I wasn’t playing my best,” is Gauff’s assessment, before my wifi checks out temporarily. While I wait for it to sort itself out, I can tell you that Gauff will face the winner of tonight’s potential blockbuster between Iva Jovic and Alexandra Eala.Gauff (4) defeats Bucsa 6-3, 6-4… and it does! 15-0, 30-0, 40-0, game, set and match Gauff. Finally, there’s an American winner on day seven, after the exits of Fritz, Keys and Anisimova, and Gauff maintains her status as one of the frontrunners for the title. She’s yet to drop a set as she punches her ticket into the second week for the fifth straight year, and she’s still only 22. How is she only 22?! It feels as if she’s been around for at least a decade.A victorious Coco Gauff (right) shakes the hand of Cristina Bucșa. Photograph: Sarah Yenesel/EPAGauff is edging closer to the last 16 herself, breaking Bucsa to 15 for 4-3 … but then is given a dose of her own medicine as she’s broken straight back to love. She comes out in the next game with the memory of a goldfish (Ted Lasso would be proud), as she charges to 0-40 … before securing another love break. It’s not often you see 11 successive points go against the server. Gauff will desperately hope that streak ends now, because she’s serving for the match at 6-3, 5-4 …An email. “Alexander Blockx was on the Changeover podcast and spoke about a superstition he picked up after his breakthrough tournament,” writes Kerrith Britland. “He apparently doesn’t change his racket throughout a match, which is pretty unheard of in professional tennis. Seems like a nice chap, humble etc and a proper talent, and anything that makes us rec players feel closer to the pros gets two thumbs up from me.” Yes, he came across really well in his on-court interview after conquering Cobolli, but I was only able to dip in and out of the match what with everything else that’s been going on today. I’ll be interested to see what he can do in the fourth round against Cerundolo – it’s a huge opportunity for both, that’s for sure.Swiatek’s victory means that Michael Zheng is now under way on Grandstand, against France’s Arthur Gea. Zheng, the 22-year-old wildcard from nearby Columbia University, who missed his own graduation a few months ago because he was qualifying for the French Open, is one of two Americans left in this half of the draw after Taylor Fritz’s defeat from two sets up earlier – the other is Learner Tien, who plays Jakub Mensik in the night session. Zheng trails 3-1 in the opening set.An entertaining drop-shot face-off between Gauff and Bucsa ends in the former’s favour and draws plenty of oooohs and aaaaaahs, but Bucsa, undeterred, still manages to move to 40-15 … before Gauff, ever the ultimate competitor – she’s Serena-like in that respect – drags herself to deuce. But Gauff gets a little over-excited and puts too much on her backhand, which drops long. So it’s advantage Bucsa … and the Spaniard holds when Gauff’s return bashes the net. It’s Gauff 6-3, 2-3 Bucsa.Coco Gauff races to reach a return. Photograph: Heather Khalifa/APGauff v Bucsa is going on serve in the second set, with Bucsa leading 2-1. Dane Sweeny, meanwhile, after his heroics in the second round against Lorenzo Musetti on his US Open debut, is finding things much tougher against another Italian opponent, Luciano Darderi, and the Australian wildcard trails 6-4, 6-3 – but Karen Khachanov has continued where he left off against Felix Auger-Aliassime, and the Russian with the hammer of a forehand leads France’s Benjamin Bonzi 6-3, 6-2.Keys has been in the press conference room after her third-set collapse earlier, and it’s really sad to hear what she had to say:
