Naomi Osaka stuns Coco Gauff to enter first US Open quarter-finals in five years; check her Grand Slam record

Naomi Osaka stunned third seed Coco Gauff 6-3, 6-2 in a highly anticipated fourth-round showdown between two former U.S. Open champions on Monday (September 1, 2025). The round of 16 showdown between the two marked the first time that they met in New York since their memorable 2019 tussle, when the then 15-year-old Gauff lost to Osaka.

Four-time Grand Slam champion Osaka produced a commendable performance and showed flashes of her old brilliance as she looked well in control of the match from the beginning, while the 2023 champion Gauff struggled with her forehand and her serve. The result carried Osaka into the Flushing Meadows quarter-finals for the first time in five years, and she will next play either Czech 11th seed Karolina Muchova or 27th seed Marta Kostyuk of Ukraine.

"It's really special. I look up to her a lot; the way she conducts herself is really special. To be such a role model at such a young age, I have respect for her," said Osaka, who triumphed in New York in 2018 and 2020, as quoted by news agency Reuters.


As the two began their battle, Osaka broke Gauff from the baseline in the first game in a superb first set. Gauff has spent many months trying to rebuild her serve and was let down by it yet again as she produced a double fault on set point, one of five across the match. The mistakes began to pile up for the American, who handed Osaka another break point with an unforced error in the sixth game of the second set and turned helplessly to her box during the final game, telling her coaches, "Nothing's working."

The pair embraced briefly at the net after Gauff bowed out with a shot into the net on match point. "I'm a little sensitive. I don't want to cry. I had so much fun out here," said Osaka, who has recaptured some of her best form this year with a run to the final in Montreal. "A big thank you to my team. We've been through a lot; it hasn't been easy, but they have been by my side. I love you."
