Coco Gauffs US Open title defence ended as Emma Navarro defeated her in the fourth round in New York. In a disjointed performance, third seed Gauff lost 6-3 4-6 6-3 to 13th seed compatriot Navarro.
Gauff committed 19 double faults, including 11 in the third set alone, ultimately handing Navarro victory with three double faults in the final game of the match.
Navarro acknowledged the significance of reaching the quarter-finals, especially as she was born in New York, adding that it felt special to play there.
Despite acknowledging the need to maintain focus after their previous meeting, Gauffs vulnerabilities on serve, including three consecutive double faults in the third set and 60 unforced errors, helped Navarro secure her spot in the Flushing Meadows quarter-finals for the first time.
Navarro will face 26th seed Paula Badosa in the quarter-finals after Badosa defeated China's Wang Yafan with a score of 6-1 6-2 earlier on Sunday.
