Two-time US Open champion Naomi Osaka earned her most impressive win since giving birth by knocking out American third seed Coco Gauff to reach the quarter-finals in New York.
Japan’s Osaka, who had daughter Shai in 2023, cruised to a 6-3 6-2 victory in an hour and four minutes.
Gauff, 21, 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 coy-but-satisfied smile before clapping Gauff, who made a hasty exit, off the court.
