The US Open 2026 has entered its decisive phase across days eight and nine, with the men's draw transformed into an unpredictable landscape far removed from the predictable seedings of tournaments past. Seeds have been eliminated across the board, and no player can assume their path to the final. Every competitor remaining understands they are navigating an opportunity that may never come again.
On 6 September, day eight opened with doubles action as Wimbledon champions Harri Heliovaara and Henry Patten faced Matteo Arnaldi and Jen-Lennard Struff. Half an hour later, Arthur Ashe Stadium hosted a significant women's fourth-round clash between defending champion Aryna Sabalenka and Taylor Townsend, a former doubles champion who has increasingly prioritised her singles career. Sabalenka arrived at this stage having dispatched Kamilla Rakhimova 6-3, 6-4 in an earlier round, while Townsend reached the fourth round after defeating Diana Shnaider 6-2, 6-7(3), 6-3. According to Tennis Explorer's live match listing, Sabalenka ultimately prevailed 6-2, 6(3)-7, 6-3 to advance further in her title defence.
The men's draw presented equally compelling narratives on day eight. Tommy Paul, one of five American men seeking to become the first home champion since Andy Roddick in 2003, faced Carlos Alcaraz. Though Alcaraz has returned to competitive form following his extended absence, the quality of opposition he now encounters tests him far more rigorously than earlier rounds have demanded. On Armstrong Stadium, Marta Kostyuk carried the weight of Ukraine and Kyiv with her as she confronted the mental barriers that have constrained her performance in her most significant matches, seeking redemption against Linda Noskova, the eventual Wimbledon champion who defeated Kostyuk in their semi-final meeting at the All England Club.
The day's other notable contests included Daniil Medvedev, a former champion who sensed another title within reach, against Francis Tiafoe, another American harbouring hopes of historic success. Jessica Pegula continued her pursuit of an elusive first Grand Slam title against Soraya Cirstea, while Alex Michelsen met Tomas Martin Etcheverry in what promised to be a closely contested battle. According to the US Open day-by-day summary for 6 September, the fourth-round schedule also featured Ben Shelton against Stefanos Tsitsipas and Anna Kalinskaya against Emma Navarro, adding further depth to an already packed day of competition.
Day nine: Swiatek, Osaka and emerging talents take centre stage
On 7 September, day nine brought fresh quarterfinal action across multiple courts. Mirra Andreeva, now a grand slam champion, faced Anastasia Potapova on Armstrong Stadium. Potapova arrived with significant momentum, having eliminated Coco Gauff in Paris and Amanda Anisimova in the previous round at the US Open, bringing a high-risk, high-reward style that promised compelling tennis.
On Arthur Ashe Stadium, Iga Swiatek, winner of the US Open in 2022, continued her dominant run through the tournament. According to tournament coverage, Swiatek had yet to lose a set in the competition, suggesting she may have rediscovered her best form. She faced Qinwen Zheng, who had demonstrated her own resilience by recovering from 0-5 down in the third set to defeat Madison Keys.
The standout match of day nine came in the second wave of singles contests, with Naomi Osaka, twice a winner of this competition, meeting Elena Rybakina, the Australian Open champion and potential world number one. Osaka had advanced with a 6-2, 5-7, 6-1 victory over Katerina Siniakova earlier in the tournament, while Rybakina had progressed with a 6-2, 6-4 win over Jessica Bouzas Maneiro. It had been some time since Osaka threatened to add to her four major titles, but her ability remained such that she could beat anyone at any time.
In the men's competition, 21-year-old Belgian Alexander Blockx faced what represented the biggest match of his career so far against Francisco Cerundolo. Blockx had dealt harshly with Flavio Cobolli in round three, coming from a set down to win 3-0, 3. Also at 21, Arthur Gea, who first caught attention by beating Jiri Lehecka in Melbourne, met Botic van der Zandschulp, whose giant serve had already helped him eliminate two seeds in Zizou Bergs and Alex de Minaur. On Armstrong Stadium, Karen Khachanov, powerful but lacking finesse, faced his inverse in Learner Tien, who possessed touch and speed but lacked raw power.
Tournament context and depth
The women's top 10 in the WTA rankings reached the third round of a Grand Slam for the first time since Wimbledon 2009, highlighting the exceptional depth of the draw at this year's US Open. This concentration of elite talent has produced unpredictable results throughout the early rounds, with multiple seeded players eliminated and emerging talents advancing further than expected.
