September 1, 2025
Naomi Osaka has eliminated Coco Gauff 6-3, 6-2 at the U.S. Open to reach her first Grand Slam quarterfinal in more than 4 1/2 years. The No. 23-seeded Osaka played far more consistent and confident tennis than No. 3 Gauff in Arthur Ashe Stadium on Monday. Osaka will meet No. 11 Karolina Muchova on Wednesday for a semifinal berth. Osaka is a 27-year-old who was born in Japan and moved to the U.S. with her family at age 3. She has won four major championships, all on hard courts. That includes titles at the U.S. Open in 2018 and 2020. Gauff’s two Slam trophies came at Flushing Meadows in 2023 and the French Open this June.
