Coco Gauff advances to US Open fourth round as Amanda Anisimova and Madison Keys exit

Coco Gauff marched into the fourth round of the US Open but compatriots Amanda Anisimova and Madison Keys exited on a mixed day for home hopes in New York.

Gauff, the most recent American champion in New York in 2023, did not have things all her own way but maintained her bid for a second triumph by overcoming Spain's Cristina Bucsa 6-3 6-4.

However, Keys said she felt "scared" as she slumped to defeat despite leading her third set against China's Zheng Qinwen 5-0, while last year's runner-up Anisimova lost in straight sets.

There could yet be as many as five American women in the last 16, with Iva Jovic hoping to join Gauff, Jessica Pegula, Taylor Townsend and Emma Navarro in the fourth round.

American players could also contest six of the eight fourth-round matches in the men's draw, with Ben Shelton, Frances Tiafoe, Tommy Paul and Alex Michelsen through - and Learner Tien and Michael Zheng still to play.

Despite the weight of expectation that she has had to deal with from a young age at her home major, the 22-year-old Gauff is through to the second week at the US Open for a fifth successive year.

Gauff, who became the first American teenager to win the US Open since Serena Williams in 1999 with her breakthrough major success three years ago, heads into the fourth round as the form player in the women's game.

Victory over Bucsa was the 2025 French Open winner's eighth straight-set WTA Tour-level win in a row.

The fourth round is where Gauff's US Open challenge ended in the previous two editions, and she admitted that she struggled to handle the pressure last year.

But in recovering from a 3-1 deficit in the first set, and producing an immediate response to being broken to love in the second, Gauff demonstrated she is better placed to cope with that this time.

"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'," Gauff said.

"There's expectations, being American, and I want to do well in front of the fans.

"Last year, I put so much pressure on myself. I'm enjoying the experience out here."

Keys appeared on course for a first fourth-round appearance at her home slam since 2023 after taking a commanding third set lead against Olympic champion Zheng.

But the 2025 Australian Open winner would miss a match point and lose each of the final seven games in a 1-6 7-6 (7-3) 7-5 loss that stunned the crowd.

The 31-year-old Keys said she felt as though she "couldn't play tennis anymore" in the final set.

"I obviously got off to a really good lead, and then I got really scared, like I couldn't swing [the racquet]," Keys said.

"I felt like I couldn't play tennis anymore. It just felt like it was a much bigger deal than just playing a tennis match all of a sudden."

Keys, who lost the 2017 US Open final to fellow American Sloane Stephens, went out in the fourth round at the other three majors in 2026.

"I feel like I've been struggling for a while now. I'm going to have to make some sort of changes," Keys said.

"I just kind of keep putting it off because that's how the tennis world works. It's just to the point where I actually need to do something about it."

Anisimova, beaten by world number one Aryna Sabalenka in last year's US Open final, lost in straight sets to Russian-born Austrian 24th seed Anastasia Potapova.

The 25-year-old was visibly frustrated with herself throughout the contest, losing her serve twice in the first set and four times in a topsy-turvy second.
