The US Open quarter-final stage has arrived, marking a decisive shift in the tournament's rhythm. The sprawling early rounds, with matches dispersed across multiple courts, have given way to concentrated focus on a single showcase stage where the remaining contenders will battle for places in the semi-finals.
Linda Noskova enters this phase as a relative newcomer to the grand slam quarter-final arena. The 21-year-old Czech player had reached only one such stage before her current run, yet she carries herself with composure on tennis's biggest platform. Facing defending champion Aryna Sabalenka presents a formidable challenge, though the defending titleholder's dominance has visibly wavered. Sabalenka has advanced through four consecutive straight-set victories, a record that masks underlying concerns. She has not won a grand slam title this year and has gone without a tournament victory since March, suffering several puzzling defeats to opponents ranked far below her. According to , Noskova reached the quarter-finals by defeating Marta Kostyuk 7-5, 5-7, 6-4, while Sabalenka advanced past Taylor Townsend 6-4, 6-3. The stakes extend beyond this single match: Sabalenka's near two-year tenure as world No. 1 will end if Elena Rybakina wins another match in New York. Should Noskova replicate the form that carried her through Wimbledon, the encounter will reveal whether Sabalenka's level and mental state remain intact.
The second quarter-final on Arthur Ashe Stadium pits two American players against each other in a generational contrast. Frances Tiafoe, now 28 years old, has reached the semi-finals of his home major twice but has never advanced to a final. According to , his path to the last eight included a straight-sets victory over 2021 US Open champion Daniil Medvedev. Alex Michelsen, a 22-year-old from California, represents the surprise package of this stage, having reached his first grand slam quarter-final without dropping a single set. Michelsen advanced by defeating Tomas Martin Etcheverry. The contrast in their positions is stark: Tiafoe carries the weight of knowing his window of opportunity is narrowing, while Michelsen arrives with minimal pressure and maximum potential. Standing 6 feet 5 inches tall with a powerful serve, Michelsen has drawn comparisons to Obi-Wan Kenobi for his ability to balance defensive solidity with attacking flair. Tiafoe's superior athleticism and recent momentum will be tested against an opponent who has shown remarkable consistency throughout the tournament.
The quarter-final stage spans two days, with the women's and men's quarter-finals scheduled to begin on Tuesday, 8 September, with Sabalenka-Noskova first and Tiafoe-Michelsen second on Arthur Ashe Stadium. The day session commences at 11:30 a.m. New York time, equivalent to 4:30 p.m. BST.
What else is happening on day 10?
Beyond the singles quarter-finals, the tournament continues across multiple disciplines. The doubles competition advances with several quarter-final matches, including action from Britain's Henry Patten and Finland's Harri Heliovaara, the top seeds and Wimbledon champions. The wheelchair events also commence on this day, with five-time US Open doubles champions Alfie Hewett and Gordon Reid among the featured competitors.
The evening session brings additional quarter-final drama. Carlos Alcaraz faces Ben Shelton in a men's quarter-final, while Jessica Pegula plays Emma Navarro in the second all-American women's quarter-final of the day. The night session will provide further opportunities for players to advance toward the semi-finals.
When do the semi-finals take place?
The remainder of the quarter-final round continues through 9 September, with the semi-finals scheduled for 10 September. This compressed schedule ensures the tournament maintains its momentum toward the final stages.
