U.S. Open 2026 Quarterfinals Wrap: Khachanov Advances, Gauff and Rybakina Reach Semifinals The quarterfinals of the 2026 U.S. Open concluded on September 9, 2026, at Flushing Meadows, with several key results shaping the semifinal matchups. On the women’s side, Coco Gauff (world No. 4) staged a dramatic comeback to defeat Mirra Andreeva (world No. 5) in three sets on Arthur Ashe Stadium. Gauff saved two match points in the final set before securing the victory, setting up a semifinal clash against Elena Rybakina (world No. 2), who advanced after a three-set win over Zheng Qinwen. Rybakina’s victory earned her the world No. 1 ranking, marking a significant milestone in her career. On the men’s side, Karen Khachanov (world No. 28) secured his place in the semifinals after a hard-fought match against Alexander Blockx (world No. 28). Blockx, who had reached the quarterfinals after defeating two higher-ranked players in his previous matches, retired during the third set due to persistent injuries to his ankle and thigh. Khachanov, who had already lost the first two sets, dominated the third set to clinch the victory in straight sets. This marked Khachanov’s third Grand Slam semifinal appearance, with his previous semifinal run dating back to the 2023 Australian Open. The final men’s quarterfinal match saw top-seeded Alexander Zverev (world No. 1) face Botic van de Zandschulp (world No. 10). The winner of this match would face Khachanov in the semifinals, setting up a potential clash between the world’s top two players. The match was anticipated to be a high-stakes encounter, with both players bringing their best form to the court.
