NEW YORK, Aug 26, 2025 (BSS/AFP) - Sixth seed Madison Keys was sent tumbling out of the US Open on Monday, losing in straight sets to lowly ranked Mexican player Renata Zarazua.

Reigning Australian Open champion Keys bowed out after an attritional battle with Zarazua, who prevailed 6-7 (10/12), 7-6 (7/3), 7-5.

Zarazua, ranked 82 in the world, took advantage of Keys' problems with her service game to claim an impressive win.

Keys gave up 14 double faults and was broken six times as Zarazua battled into a second-round meeting with France's Diane Parry.

Keys' defeat comes after a solid season in Grand Slams following her maiden victory at the Australian Open in January. She reached the quarter-finals at the French Open before progressing to the third round at Wimbledon.
