Osaka upsets Gauff in US Open: Highlights from Round of 16 match

NEW YORK — The last time Coco Gauff and Naomi Osaka met at the US Open six years ago, the emotions for a then-15-year-old Gauff were overwhelming, with her bursting into tears at the end of the 6-3, 6-0 third-round defeat.

It was Gauff’s first appearance on the big stage of Arthur Ashe Stadium, but on Monday, a resurgent Osaka was the one fighting back tears. The No. 23 seed again got the best of her fellow former US Open champion and someone she affectionately calls her ‘little sister,’ advancing to the quarterfinals with a rather efficient 6-3, 6-2 victory in front of a packed Arthur Ashe Stadium on Sept. 1, 2025.

Gauff’s issues from earlier matches in the tournament reared their ugly head again, with a flurry of unforced errors and double faults, putting her down early as Osaka, a two-time winner at Flushing Meadows, sat back, waited patiently to capitalize on every mistake, and worked her forehand to win points along the baseline.

The problems started early, as Gauff, the No. 3 seed, was broken on her initial serve. Then, serving to stay in the first set, she started off with an ace but faltered, double-faulting twice, the last one giving Osaka the set.

Gauff was serving to stay in the match, and held a 40-15 lead, only to suffer another meltdown, and Osaka celebrated her victory when Gauff’s return of her effective forehand return hit the net.

It is the fifth time Osaka has reached a Grand Slam quarterfinal, and she has gone on to win that title each time. She also advanced to the quarterfinals for the first time since the 2021 Australian Open, the last of her four Grand Slam titles.

“I’m a little sensitive and I don’t want to cry, but I had so much fun out here,’ Osaka said in a post-match interview. ‘I was in the stands two months after I gave birth to my daughter, watching Coco. I really wanted an opportunity to come out here and play. This is my favorite court in the world. It means so much to me to be back here. ‘

“I look up to her. The way she conducts herself is really special. To be such an amazing role model at such a young age, it’s a gift. I have all the respect in the world for her.’

Osaka’s quarterfinal opponent will be No. 11 seed Karolína Muchová, a 6-3, 6-7 (0-7), 6-3 winner over No. 27 seed Marta Kostyuk.
