Navarro Ends Gauff's US Open Title Defense.

Coco Gauff's attempt to defend her US Open title came to an end when she lost to Emma Navarro in the fourth round in New York.

Third-seeded Gauff delivered an uneven performance, falling 6-3, 4-6, 6-3 to 13th-seeded Navarro. 

Gauff struggled with 19 double faults, including 11 in the third set and three in the final game, which contributed to Navarro's win.

Navarro, reflecting on her progress, said, "I lost in the first round the last two years, so making the quarter-finals now is pretty incredible."
