Americans Tiafoe, Shelton reach US Open quarterfinals

American Frances Tiafoe advanced to the U.S. Open quarterfinals on Sunday, September 6, 2026, defeating former champion Daniil Medvedev in a straight-sets victory at Louis Armstrong Stadium. Tiafoe secured his place in the final eight with a 7-6(1), 6-4, 7-6(6) win, marking a significant personal milestone against an opponent he had struggled against in previous encounters. The victory was Tiafoe's first against Medvedev in a standard tour match, improving his career head-to-head record against the Russian to 2-7. Prior to Sunday's match, Tiafoe had lost six of his seven previous meetings with Medvedev. The contest lasted nearly three hours, with Tiafoe demonstrating strong play, including precise net work and serve-and-volley tactics. He won the opening tiebreak decisively and held his nerve in a tight third-set tiebreak to close out the match. Tiafoe's win extends his flawless record at Louis Armstrong Stadium to 10-0. The American, who reached the final of the Cincinnati Open last week, has now won his last three matches at the U.S. Open in straight sets. This quarterfinal appearance is his fourth at the New York tournament.
