American tennis players Taylor Fritz and Frances Tiafoe have advanced to the quarterfinals of the U.S. Open, raising hopes for a potential end to the 21-year drought since an American man last won a Grand Slam singles title. Fritz, seeded No. 12, defeated No. 8 seed Casper Ruud, while Tiafoe, the No. 20 seed, overcame Alexei Popyrin in a four-set match. Both players emphasized the importance of their mutual support in improving their performances. Fritz made history by becoming the first American man since Andre Agassi in 2003 to reach the round of 16 at all four Grand Slam tournaments in a single year. He is determined to advance beyond the quarterfinals this time, having previously reached that stage three times without a final appearance. The next matches will be crucial as Fritz faces No. 4 seed Alexander Zverev, and Tiafoe meets No. 9 seed Grigor Dimitrov.
