US Open 2025: Osaka beats Kasatkina to set up last-16 clash with Coco Gauff; check full match report

Naomi Osaka stormed into the fourth round (last 16) of the US Open on Saturday (August 30, 2025) after defeating 15th seed Daria Kasatkina 6-0 4-6 6-3. The four-time major champion Osaka bagged a victory in the third-round clash after showcasing power and composure. She will now face American third seed Coco Gauff in the next round.

The Japanese player dominated in the early going and surived a brief second-set wobble, and closed out the win to set up a blockbuster fourth-round showdown with Gauff. "Honestly, I was trying to tell myself to stay calm. I was so shaky today but I'm glad that it was an entertaining match," Osaka said, as reported by news agency Reuters. “Whenever I come here it feels like home and you guys are very involved and I feel grateful, thank you,” she said. "Can someone come to the match and cheer for me?," the 27-year-old added.

"I mean it's kinda tough playing an American here but I hope you guys have adopted me. I kinda see her as a little sister so it's cool to be playing her here." Osaka managed to put pressure on Kasatkina with an early break gifted to her by a double fault before racing into a 3-0 lead. Kasatkina's delivery deserted her in the first set with eight double faults and only 25% of first serves landing as Osaka coolly dished out a bagel in 22 minutes.


The 15th seeded Russian, however, came back from behind and forced a decider following a scrappy second set riddled with breaks. Osaka's frustration surfaced, and Kasatkina steadied enough to seize the lead.

Seven service breaks kept the set on edge before the Russian-born player finally held her nerve to level the match. Osaka, however, regained her composure in the third. She saved a break point with two blistering winners and surged into a 3-1 lead before closing out the match to stay on course for a third U.S. Open title.
