Coco Gauff’s US Open title defence is over after she was beaten by Emma Navarro in the fourth round in New York.
Third seed Gauff produced a disjointed performance to lose 3-6 6-4 3-6 to fellow American and 13th seed Navarro.
Gauff hit 19 double faults, with three in the final game helping secure victory for Navarro and send her into a first Grand Slam quarter-final.
The 23-year-old will play Spanish 26th seed Paula Badosa in the last eight after she thrashed China’s Yafan Wang 6-1 6-2 earlier on Sunday.
