Jannik Sinner takes his U.S. Open title defense into the semifinals by beating Musetti

The No. 1 seed continued what's been an easy title defense and on Friday will face No. 25 seed Felix Auger-Aliassime, who beat No. 8 Alex de Minaur 4-6, 7-6 (7), 7-5, 7-6 (4). Sinner is into his fifth straight Grand Slam semifinal and with a win Friday would reach the finals of all four majors this year. Musetti was trying to reach his first U.S. Open semifinal after getting that far at the French Open this year and Wimbledon in 2024.
