American eighth seed Amanda Anisimova pulled off one of the biggest surprises of the 2025 US Open, defeating world No. 2 Iga Swiatek 6–4, 6–3 in the quarterfinals on September 3 at Arthur Ashe Stadium. The victory secured her first-ever semifinal berth in New York and served as redemption after a painful Wimbledon final loss to the Pole earlier this summer. (reuters.com, washingtonpost.com)

At Wimbledon in July, Swiatek had humiliated Anisimova in a 6–0, 6–0 “double-bagel” final — one of the most lopsided Grand Slam deciders in modern tennis. Wednesday’s match in New York, however, told a very different story. Anisimova showcased resilience and composure, breaking Swiatek’s serve at crucial moments while dictating rallies with her improved groundstrokes and tactical patience.

The first set swung in Anisimova’s favor after she fought back from an early break, while in the second she built momentum with aggressive returns that left Swiatek struggling to regain control. The match lasted just under 90 minutes, but it carried the emotional weight of months of hard work and recovery for the American. (tennis.com)

Speaking after the win, Anisimova called the result “a dream come true” and admitted it was particularly meaningful after the heartbreak of Wimbledon. She highlighted her ability to reset mentally and trust her game plan: “This was about believing in myself again.” (talksport.com)

Swiatek, meanwhile, cut a frustrated figure in her press conference, even sparring with a reporter over a pointed question about her performance. Despite the exit, she remains world No. 2 and is expected to regroup ahead of the WTA Finals later this year. (nypost.com)

For Anisimova, the victory sets up a high-profile semifinal clash against Japan’s Naomi Osaka, who advanced earlier by defeating Karolina Muchova. Tennis fans are eagerly anticipating the showdown, with both players known for their power-based games and strong baseline play. A potential final against either Coco Gauff or Aryna Sabalenka also looms, adding further excitement to the women’s draw. (independent.co.uk)
