Italian top seed Jannik Sinner defeated Briton Jack Draper 7-5, 7-6(3), 6-2 to reach the U.S. Open final, despite suffering a wrist injury and Draper vomiting due to the humid conditions. This marks Sinner's second major final this year after winning the Australian Open. In the women's final, Jessica Pegula overcame a tough start to defeat Karolina Muchova 1-6, 6-4, 6-2, setting up a championship match against Aryna Sabalenka. Pegula, playing in her first Grand Slam final at age 30, becomes only the third American woman aged 30 or over to reach a U.S. Open final, joining Serena Williams and Martina Navratilova. Aryna Sabalenka, last year's runner-up, aims to win her first U.S. Open title after defeating Emma Navarro. The finals guarantee American participation in both the men's and women's singles for the first time since 2002.
