No. 6 seed Madison Keys was bounced from the U.S. Open in the first round when she fell 6-7 (10), 7-6 (3), 7-5 to unseeded Renata Zarazua of Mexico on Monday at New York.

The match was on serve in the fifth set until Zarazua broke Keys for a 5-3 advantage. Keys broke back in the next game with the final set even at 6-6 when Zarazua broke Keys again to win on her first match point.

It was the first victory over a top-20 player in Zarazua’s career as she grabbed her head in disbelief after securing the win. She is the first Mexican woman ever to defeat a top-10 opponent at the U.S. Open.

Zarazua took advantage of 89 unforced errors from Keys and won despite her opponent’s 46-8 advantage in winners.

Keys had seven aces to none for Zarazua in the 3-hour, 10-minute match, but had 14 double faults to five for her opponent.

Zarazua saved seven of Keys’ 12 break-point opportunities, while converting six of 10 break-point chances.

Zarazua advanced to meet France’s Diane Parry in the second round. Parry was an easy 6-1, 6-0 winner in the first round against Czechia’s Petra Kvitova.
