Iga Swiatek’s Miami Open collapse has cost more than just ranking points. Less than 24 hours after a 6‑1, 5‑7, 3‑6 loss to compatriot Magda Linette ended her 73‑match streak in opening rounds, the world No. 1 called time on her 17‑month partnership with coach Wim Fissette. The pair, who joined forces in late 2024 and celebrated titles on three surfaces, including a career‑defining Wimbledon, had endured a stuttering start to 2026. For Swiatek, this latest defeat was the signal that something had to change.

Swiatek described the Miami Open as “challenging” but also said that she has learned a lot due to her early exit from the competition.

“Sometimes life and sport bring moments like this… Miami was challenging for me. I feel disappointment, bitterness and responsibility for my performance on the court of course. I’ve also learned a lot of important lessons and I think that’s very human,” her Instagram post read.

Reflecting on her time with Fissette, Iga Swiatek expressed her gratitude for his constant support and thanked him for helping her achieve one of her biggest dreams.

“That being said, after many months of working together with my coach @fissettewim I’ve decided to take a different path. It was an intense time full of challenges and many important experiences. I’m grateful for his support, experience, and everything we achieved together – including one of my biggest dreams in sport.”
