Sinner is into his fifth straight Grand Slam semifinal and with a win Friday would reach the finals of all four majors this year. He has won 26 consecutive matches in majors on hard courts. That includes the past two Australian Open titles along with his triumph in New York a year ago.
He needed just 2 hours Wednesday—the first set took only 27 minutes—fighting off all seven break points he faced. He has dropped just 38 games in his five matches, the second-fewest by a man to reach the US Open semifinals since 2020.
Musetti was trying to reach his first US Open semifinal after getting that far at the French Open this year and Wimbledon in 2024.
