Naomi Osaka and Amanda Anisimova have stormed into the semi-finals of the US Open 2025, delivering two of the most compelling performances of the tournament so far. Osaka, the former world No. 1 and two-time US Open champion, defeated Karolína Muchová in straight sets 6–4, 7–6(3), marking her first Grand Slam semi-final appearance since 2021. Meanwhile, Anisimova pulled off a seismic upset over second seed Iga Swiatek, winning 6–4, 6–3 in a match that served as poetic revenge for her crushing Wimbledon final loss just two months ago.
The victories set up a high-voltage semi-final clash between Osaka and Anisimova, two players on very different comeback arcs—Osaka returning from maternity leave and Anisimova rewriting her narrative after a career-low moment.
🧭 Quarterfinal Results Overview
| Match | Winner | Scoreline | Key Highlights |
|---|---|---|---|
| Naomi Osaka vs Karolína Muchová | Naomi Osaka | 6–4, 7–6(3) | Osaka’s composure, Muchová’s injury struggles |
| Amanda Anisimova vs Iga Swiatek | Amanda Anisimova | 6–4, 6–3 | Redemption arc, fearless baseline play |
Osaka extended her perfect record in Grand Slam quarterfinals and beyond to 13–0, while Anisimova avenged her 6–0, 6–0 Wimbledon final loss with one of the most meaningful wins of her career.
🔍 Naomi Osaka’s Comeback Story
Osaka’s journey back to the top has been nothing short of inspiring. After giving birth to her first child in 2023, she returned to the tour with modest expectations. But her performance in New York has reignited memories of her dominant hard-court runs.
Against Muchová, Osaka showcased her trademark power and precision, landing 60% of her first serves and breaking at crucial moments. Muchová, who had spent over 10 hours on court in previous rounds, struggled with mobility and required a medical timeout for a strapped thigh.
Osaka’s ability to stay composed during tense rallies and execute clean winners in the tie-break proved decisive. “It feels incredible to be back in the semi-finals here,” she said post-match. “I knew I had to stay composed against Karolína because she always fights until the end. I just tried to focus on my serve and take my chances”.
📉 Amanda Anisimova’s Redemption Arc
Anisimova’s win over Swiatek was more than just an upset—it was a statement. Just 53 days after suffering a humiliating 6–0, 6–0 defeat in the Wimbledon final, the 23-year-old American flipped the script with fearless aggression and tactical clarity.
She converted four of nine break points, won 67 of 121 total points, and delivered three aces with a 71% first-serve success rate. Swiatek, by contrast, faltered with three double faults and was broken four times.
“Playing here is so freaking special,” Anisimova said. “To come back from Wimbledon like that is really special to me. I worked so hard to turn things around, and today proved everything—I can do it”.
