**U.S. Open Underdogs Roar Back: Osaka & Auger-Aliassime Surge into Quarter-Finals**

**New York, September 2nd, 2025** – The U.S. Open witnessed a stunning Labour Day Monday as Naomi Osaka and Felix Auger-Aliassime delivered dominant performances, defying expectations and securing spots in the quarter-finals after periods of relative absence from Grand Slam contention.

Osaka, the four-time major champion, showcased her vintage form with a decisive 6-3 6-2 victory over third seed Coco Gauff. Osaka’s powerful and poised display at Arthur Ashe Stadium marked her first Flushing Meadows quarter-final appearance in five years. “I had so much fun out here,” Osaka said, visibly emotional after the win.

Auger-Aliassime mirrored Osaka’s resurgence, overcoming 15th seed Andrey Rublev in a composed 7-5 6-3 6-4 victory. This win propels him into his first major quarter-final since the 2022 Australian Open, capping a comeback from injuries and confidence struggles. “Today is my first time playing Arthur Ashe in a few years. It feels even better than the first time,” Auger-Aliassime stated, highlighting the significance of his return.

Iga Swiatek continued her dominant season, dismantling Ekaterina Alexandrova, becoming the youngest woman since Maria Sharapova in 2005 to reach the quarter-finals of all four Grand Slams in a single season.

Both Osaka and Auger-Aliassime credited improved mental fortitude as key to their success. Osaka emphasized gratitude and enjoyment, while Auger-Aliassime focused on maintaining composure under pressure.

Looking ahead, Auger-Aliassime will face eighth seed Alex de Minaur, while Osaka is set to clash with 11th seed Karolina Muchova.

The evening session promises further excitement, with defending champion Jannik Sinner facing Alexander Bublik. American Amanda Anisimova is also set to compete against Beatriz Haddad Maia.

Earlier in the day, Venus Williams, partnered with Leylah Fernandez, continued their improbable doubles run, advancing with a 6-3 6-4 victory.
