Two-time US Open champion Naomi Osaka earned her most impressive win since returning to the tour by knocking out American third seed Coco Gauff to reach the quarter-finals in New York.
Japan's Osaka, who gave birth to a daughter in 2023, cruised to a 6-3 6-2 victory in an hour and four minutes.
Gauff, 22, came into her home Grand Slam clouded by uncertainty in her game and it showed in a subdued performance.
Former world number one Osaka played patiently to draw mistakes out of her opponent, whose forehand was particularly unable to cope with the scrutiny.
Osaka, seeded 23rd, broke into a beaming smile before clapping Gauff, who made a hasty exit, off the court.
The victory is Osaka's biggest win by ranking since beating then-world number one Ashleigh Barty at the China Open in 2019.
"I'm a little sensitive, I don't want to cry - I had so much fun out here," she said.
"I was in the stands two months after giving birth to my daughter watching Coco and I really wanted an opportunity to come out and play.
"It's my favourite court in the world and it means so much to be back out here."
