World No. 1 Jannik Sinner Faces Felix Auger-Aliassime in US Open Semifinals

The 2025 U.S. Open men's singles semifinal features top-ranked and defending champion Jannik Sinner facing No. 20 Felix Auger-Aliassime at Arthur Ashe Stadium. Sinner, who has won three of the last four Grand Slam tournaments including Wimbledon and the 2024 U.S. Open, aims for his fifth consecutive Grand Slam final appearance. Auger-Aliassime, seeking his first Grand Slam title, has previously reached the U.S. Open semifinals in 2021 but fell short. Their match is scheduled for September 5 at 7 p.m. ET, airing on ESPN and streaming via several platforms including ESPN Unlimited and Disney Plus. Analysts highlight Sinner's dominant 2025 season, including a 26-match hard court winning streak, making him the favorite against Auger-Aliassime, who has shown resilience by defeating multiple top-15 players this year. The pair have met four times before, with Auger-Aliassime leading 2-1 until Sinner's recent decisive victory in 2025, adding intrigue to this anticipated rematch.
