Madrid, Spain – In a stunning turn of events at the Mutua Madrid Open, World No. 4 Iga Swiatek was forced to retire from her third-round match against American Ann Li due to illness, marking a significant upset in the WTA 1000 tournament. The match, which took place on Saturday, April 25, 2026, saw Swiatek retire trailing 7-6(4), 2-6, 3-0 in the deciding set after battling gastrointestinal issues that worsened throughout the contest.
The Polish star, who entered the tournament as a top contender, showed signs of distress early in the match but managed to push through the first two sets. However, her condition deteriorated in the third set, leading to a medical timeout before she ultimately decided she could not continue. Li, ranked No. 34 in the world, capitalized on the opportunity to secure her second career top-10 victory and her best result ever at a WTA 1000 event, advancing to the fourth round where she will face Leylah Fernandez.
Swiatek’s retirement came after she had taken a medical timeout down 0-2 in the third set. Upon returning to the court, Li held serve at love, and Swiatek retired officially a few points into the fourth game. The Polish player later revealed she had been suffering from a virus, stating, “The past two days were pretty terrible, I think I have some virus. It’s been some hours fine, some hours pretty bad. I had zero energy, zero stability, and I just felt really bad physically.” This explanation aligned with her visible struggles on court, where she appeared to lack her usual stability and energy.
Despite the unfortunate complete, Li acknowledged the difficulty of the situation, expressing sympathy for her opponent while also recognizing her own performance. “Definitely knew it was going to be a tough match, I’m super sorry for her that she’s had to pull out, it’s never easy to go like that,” Li said to the press. “I was just super proud of the way that I fought and I pushed through.” Her resilience was evident throughout the match, particularly in the opening set where both players saved set points before Li prevailed in a tight tiebreak.
The victory represents a significant milestone for Li, marking her highest-ranked win to date and her fifth career victory over a former Grand Slam champion. Her previous top-10 win came more than four years ago when she defeated Anett Kontaveit at the Miami Open. This triumph also secured her second career appearance in the Round of 16 at a WTA-1000 event, following her run in Doha earlier in the year.
Swiatek’s retirement adds to a challenging clay court season for the Polish star, who has struggled to defend her titles on the surface. She entered the Madrid Open with a singles record of 14-8 and zero titles in 2026, having failed to win more than one match in the two clay court tournaments she had contested prior to Madrid. The loss means she will not be able to defend her Madrid title from the previous year, further complicating her efforts to regain consistency on her preferred surface.
Looking ahead, Li will now face Canadian Leylah Fernandez in the fourth round of the Mutua Madrid Open. Fernandez, who advanced through her own third-round match, presents a formidable challenge as Li seeks to build on her momentum from the upset victory over Swiatek. The match is scheduled to take place in the coming days, though exact timing will depend on the tournament’s order of play.
For Swiatek, the immediate focus will be on recovery and preparation for upcoming tournaments. While her withdrawal from Madrid is a setback, her ranking remains secure given the points gap to her closest competitors. The Polish star will aim to return to full health in time for the European clay court swing, with her sights set on regaining form ahead of the French Open.
As the Mutua Madrid Open continues without one of its biggest stars, the tournament gains added intrigue with other top players vying for the title. The absence of Swiatek, along with earlier withdrawals of Carlos Alcaraz and Novak Djokovic, has opened up the draw significantly, creating opportunities for players like Li and Fernandez to make deep runs.
The incident serves as a reminder of the physical demands of professional tennis and the fine line athletes walk between pushing through adversity and knowing when to step back for their health. Swiatek’s decision to retire, while disappointing for fans, underscores the importance of prioritizing well-being in elite sports.
