Elena Rybakina is one win away from the world No. 1 ranking after she overpowered Naomi Osaka, registering a 6-1, 6-4 victory in Louis Armstrong Stadium on Sunday. Coco Gauff dismantled Iva Jovic 6-1, 6-4 in 80 minutes to reach the quarterfinals for the first time since winning the 2026 US Open (WTA) title three years ago, remaining undefeated in New York this fortnight. Zheng Qinwen has compiled an improbable run through the women's draw, erasing another 5-0 deficit to stun six-time Grand Slam champion Iga Swiatek 7-5, 6-3 and advance to the quarters after qualifying and two major upsets; Swiatek will finish the year without a Grand Slam title.
On the men's side, top-seeded Alexander Zverev beat Luciano Darderi in straight sets Monday night to reach the quarterfinals, while American Learner Tien fell to Karen Khachanov. Off court, Rybakina sent a warning to rivals in her pursuit of the top ranking, saying the team's main focus is to win titles. Arthur Gea held match point to become the first lucky loser to reach a Grand Slam quarter-final before falling on the same day, denied history in a cruel twist. The 2026 US Open (ATP) and 2026 Shanghai (ATP) continue this week, with quarterfinals set to unfold on both the men's and women's sides in New York.
