Naomi Osaka powered past third seed Coco Gauff 6-3, 6-2 to reach her first US Open quarterfinal since 2019, showing glimpses of her past brilliance. Gauff struggled with her serve and forehand, committing errors that allowed Osaka to dominate. The four-time Grand Slam winner, who last won a major in 2021, credited her comeback to belief, fun, and support from her team after struggles with mental health and a maternity break. She next faces Karolina Muchova. Meanwhile, Iga Swiatek eased past Ekaterina Alexandrova 6-3, 6-1 to make her 13th major quarterfinal and will meet Amanda Anisimova next.
