Iga Swiatek stunned, Naomi Osaka advances in the Canadian Open

Wimbledon champion Iga Świątek, the second seed in Montreal, suffered a stunning upset in the round of 16 at the Canadian Open on August 3, 2025, falling to Denmark’s Clara Tauson, seeded 16th. Tauson triumphed in straight sets—7‑6 (7‑1), 6‑3—in swirling winds, using bold shotmaking and calm under pressure, especially after being broken in the second set. Świątek’s backhand drifted into the net at a critical moment, sealing the surprise victory. 

Tauson now faces American Madison Keys in the quarterfinals. Keys survived two match points to beat Czech Karolina Muchova 4‑6, 6‑3, 7‑5, continuing a season that includes her first Grand Slam title at the Australian Open. Meanwhile, Naomi Osaka, the former world No. 1, delivered one of the most dominant performances of the tournament. In just 49 minutes, she dismantled Anastasija Sevastova 6‑1, 6‑0, dropping only one game to reach her first WTA 1000 quarterfinal since Doha in early 2024. “I had a solid plan coming in here, and it worked very well,” Osaka said, confident in her tactics. 

These results cap off a run of early exits from top seeds, Coco Gauff, defending champion Jessica Pegula, and Mirra Andreeva all bowed out in the opening rounds, making Montreal one of the most unpredictable WTA events of the season. As the draw tightens, Osaka’s resurgence contrasts sharply with Świątek’s disappointing departure. Tauson and Keys seem poised for an exciting quarterfinal duel, while Osaka looks to sustain her momentum on the North American hard courts and raise new questions ahead of the U.S. Open later this month.
