Frances Tiafoe defeated No. 7 seed Daniil Medvedev in straight sets, 7-6 (7), 6-4, 7-6 (8), to reach the U.S. Open quarterfinals. Tiafoe, the No. 11 seed, becomes the first player to take a set from Medvedev in this year's tournament. Medvedev had previously won his first three matches in straight sets.
Tiafoe's victory took place on Louis Armstrong Stadium, a court he has dubbed the “people’s court.” Following the win, he noted his perfect 10-0 record on that particular court. The match marked a significant upset, with Tiafoe being the only player to secure a set against the Grand Slam winner Medvedev during the U.S. Open thus far.
Tiafoe will now face fellow American Alex Michelsen in the quarterfinals. The win secures Tiafoe's progression in the tournament after a strong showing against a highly-ranked opponent. The match was played on Sunday, Sept. 6, 2026, at the U.S. Open Tennis Championship in Flushing Meadows, Queens, N.Y.
