NEW YORK — Coco Gauff began her US Open campaign with a confident 6-3, 6-4 victory over Zeynep Sonmez of Turkey, advancing to the second round at Flushing Meadows. The No. 4 seed and 22-year-old American won the title here in 2023 and added a second Grand Slam crown at Roland Garros in 2025.
Gauff, competing in her eighth US Open main draw, entered the tournament in fine form, having reached the semifinals at Wimbledon and Toronto and won the title in Cincinnati. She dominated the opening set, breaking Sonmez for a 4-2 lead and closing it out in 32 minutes.
Sonmez, ranked 53rd, rallied in the second set, charging the net to change momentum and recovering an early break. The Turkish player forced three break points, but Gauff saved all three, holding on the 16th point of the game and then breaking to take a 4-3 lead she would not relinquish.
"I think I was just trying not to panic," Gauff said. "She started coming to the net and playing great tennis. That 3-all game was real important."
Gauff posted two aces and a service winner in her first service game, and her serve proved a key asset throughout the match. The victory keeps alive her chance to finish the tournament as the world No. 1, a position she has never held in singles; her previous high was No. 2, achieved in June 2024. Next up for Gauff is a second-round match against either Paula Badosa or Daria Kasatkina.
Rybakina cruises, Andreeva dominant
World No. 2 Elena Rybakina also advanced comfortably, beating US teenager Thea Frodin 6-3, 6-2. Rybakina, who won Wimbledon in 2022, showed little sign of the left heel injury that forced her out of her quarterfinal in Cincinnati this month. She saved both break points she faced in a polished performance against Frodin, who was playing her first Grand Slam main draw match on a wild card.
"I'm happy with the match. Especially when you don't know your opponent, it always can be dangerous, but overall I'm happy with the first match and how it went," said Rybakina, who added: "It's a great result after 10 days from that kind of injury." She is still carefully managing her training, rest and treatment.
Rybakina and Gauff are two of three players, along with No. 3 Jessica Pegula, who have a chance to supplant Aryna Sabalenka atop the world rankings at the US Open. Gauff would need to win the title for a second time, while Rybakina could reach No. 1 by reaching the semifinals.
French Open champion Mirra Andreeva, seeded fifth, also advanced with ease, beating Indonesia's Janice Tjen 6-2, 6-2. The 19-year-old Andreeva, who has a 14-1 record in Grand Slam first-round matches, will face Eva Lys in the second round.
