Defending champion Coco Gauff became the latest big-name casualty to exit the U.S. Open when Emma Navarro won their fourth round match 6-3 4-6 6-3 to down her stunned American compatriot for the second time in a Grand Slam this year.

Gauff was her own worst enemy, however, especially on serve where the 20-year-old third seed struggled and had 19 double faults — as many as she had in her first three matches combined — while she also made 60 unforced errors.
