Frances Tiafoe and Alex Michelsen, both Americans, meet in the US Open quarterfinals after strong fourth-round wins on September 6-7. The 11th-seeded Tiafoe (ranked around 12) defeated seventh seed Daniil Medvedev 7-6(1), 6-4, 7-6(6) for his first regular-match victory over the Russian and his fourth US Open quarterfinal appearance in five years, extending a perfect record in Louis Armstrong Stadium. Unseeded Michelsen (ranked 46) continued his set-free run with a 7-6(6), 6-4, 6-4 victory over 27th seed Tomas Etcheverry, showcasing strong serving and composure in his first Grand Slam quarterfinal.
