US Open 2025: Anisimova Stuns Swiatek in Quarterfinal Upset; Auger-Aliassime Survives Grueling Match to Advance

Iga Swiatek’s run in the 2025 US Open met with a shocking end on Wednesday as Amanda Anisimova powered past her 6-4, 6-3 in the quarterfinals. It was a rematch of July’s Wimbledon final, where Swiatek had crushed the American 6-0, 6-0. This time, Anisimova dictated play with fearless shot-making to reach her first semifinal in New York. “What I learned then and also throughout this tournament, I feel like with each match that I've played I tell myself to really not go into the match with fear,” the 24-year-old American said. “Today, I came out with not an ounce of fear.”Four-time Grand Slam champion Naomi Osaka held off Karolina Muchova 6-4, 7-6 (3) to stay unbeaten in major quarterfinals. Osaka moves into the last four, joining Anisimova in what promises to be an unpredictable finish at Flushing Meadows.Go Beyond The Boundary with our YouTube channel. SUBSCRIBE NOW!
