MIAMI – In a significant shift for the world of women’s tennis, Iga Świątek and her coach, Wim Fissette, have parted ways after an 18-month partnership that yielded a Wimbledon title and a period of intense on-court evolution. The announcement, made via Instagram on Monday, comes on the heels of a surprising second-round loss at the Miami Open to Magda Linette, a result that ended Świątek’s remarkable 73-match winning streak in opening rounds dating back to 2021. The split marks a turning point for the 22-year-vintage Polish star as she prepares for the clay-court season and the defense of her French Open crown.
The decision, while not entirely unexpected given Świątek’s recent struggles with consistency, underscores the challenges of reshaping a game while maintaining peak performance. Fissette, 46, brought a wealth of experience to the collaboration, having previously guided Kim Clijsters, Angelique Kerber and Naomi Osaka to Grand Slam victories, as well as Simona Halep and Sabine Lisicki to major finals. His arrival in October 2024 was intended to refine Świątek’s game, moving away from the purely aggressive style that had propelled her to four major titles and toward a more nuanced, counterpunching approach.
Still, that transition proved complex. While the partnership delivered success – including the 2025 Wimbledon championship, the Cincinnati Open, and the Korea Open – it also coincided with periods of visible frustration for Świątek, particularly during matches. The attempt to blend old and recent techniques sometimes appeared to hinder her on court, leading to inconsistent results and, as she herself acknowledged after the Miami defeat, a feeling of being caught between styles. “You can’t do, like, one huge step and suddenly it’s not going to — there’s no magic solutions,” Świątek told reporters, as reported by Bounces. “So I guess you require to do it with small changes, but kind of consistently, and keep your discipline.”
A Wimbledon Triumph and a Search for Consistency
Fissette’s tenure began with a clear objective: to build upon Świątek’s already formidable foundation. The initial phase saw positive results, culminating in a dominant run at Wimbledon in 2025. Świątek’s ability to combine power with tactical awareness was on full display, solidifying her position as a leading force in women’s tennis. However, maintaining that level of performance proved difficult. The 2026 season began with a mixed bag of results, and the Miami Open loss to Linette – a player ranked No. 50 in the world – exposed vulnerabilities in Świątek’s game.
Świątek’s Instagram post announcing the split reflected a sense of both disappointment and acceptance. “Miami was challenging for me,” she wrote. “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. … Wim, thank you for this time and for the lessons I’ve learned thanks to you. I wish you all the best – both professionally and personally.” Fissette reciprocated with a message of support, stating, “We both wanted and worked for more but shared important moments and lessons. Iga, I now wish you good luck and success in what’s next. I’m sure you will have it.”
Internal Dynamics and a Recent Suspension
Beyond the technical aspects of the coaching relationship, reports suggest internal team dynamics also played a role in the decision. During recent losses, including a quarterfinal defeat to Elina Svitolina at the BNP Paribas Open in Indian Wells, Świątek reportedly expressed frustration with her support team, which includes her long-term psychologist, Daria Abramowicz. This tension highlights the complexities of managing a high-performance athlete and the delicate balance between coaching, psychology, and player autonomy.
Adding another layer to the situation, Fissette was also Świątek’s coach during a one-month suspension stemming from a positive test for trimetazidine (TMZ) in September and October 2024. The suspension caused Świątek to miss three events and relinquish her world No. 1 ranking. As of March 20, 2026, Świątek is ranked No. 3 and will fall to No. 4 if Coco Gauff advances to the final of the Miami Open. The International Tennis Federation (ITF) maintains detailed information on anti-doping regulations and results on its website: www.itftennis.com.
Looking Ahead: The Clay Court Season and Beyond
Świątek’s next scheduled tournament is the Stuttgart Open in Germany in mid-April, marking the start of her clay-court season. Clay has historically been her most successful surface, with four of her six Grand Slam titles coming at the French Open. However, she experienced a dip in form on clay last year, failing to win a title and losing in the semifinals at Roland Garros – her first defeat at the tournament in four years.
Analysts suggest that addressing her serve will be a key priority for her next coach. As James Hansen, senior managing editor for tennis, noted, Świątek’s serve, while accurate, lacks the power to consistently earn free points, placing greater pressure on her baseline game. Improving her serve could provide a crucial release valve and allow her to dictate points more effectively. The challenge will be finding a coach who can assist her refine her technique without disrupting the core strengths that have made her a dominant force in the sport.
The search for a new coach is now underway, and the decision will undoubtedly shape the trajectory of Świątek’s career. The coming months will be crucial as she prepares for the French Open and aims to regain her position at the top of the women’s game. The focus will be on finding a collaborative partnership that can unlock her full potential and address the vulnerabilities exposed during this period of transition.
The next major checkpoint for Świątek will be the French Open qualifying rounds, beginning May 26, 2026. Fans and analysts alike will be watching closely to witness how she adapts to her new coaching setup and whether she can rediscover the form that made her a Grand Slam champion.
