Iga Swiatek's Madrid Run Ends Early: Virus on Site, Zero Energy, Retirement After One Set

Iga Swiatek walked off the court at the Mutua Madrid Open on Saturday and didn't come back. The No. 4 seed and six-time Grand Slam Champion withdrew from her round-of-32 match against Ann Li after battling illness that left her physically devastated. She made it through the second set after trailing in the first, but when the third set started going sideways, Swiatek called for the medical team. They cleared her to continue, but after Li held serve to go up 2-0, Swiatek retired from the match.

What Happened on Court

This was brutal to watch unfold. Swiatek lost the opening set to the No. 31 seed Li, then fired back hard in the second. She ripped off a 4-0 lead and won 16 of 21 points in that set, closing it out in 39 minutes. But something was clearly off. You could see it. The illness was eating at her even as she was winning points. Down 2-0 in the third, she signaled for the medical timeout. The doctors checked her out, she tried to gut it out, but after Li held serve, Swiatek had nothing left. She retired.

Li, the No. 31 seed, walked away with the biggest win of her career. It's her second Top 10 victory in 12 tries. She'll face No. 24 seed Leylah Fernandez of Canada in the Round of 16 on Monday.

The Real Problem: Madrid Isn't a Safe Harbor Anymore

This exit stings because Swiatek won Madrid just two years ago. She's appeared in the tournament five times now, and this is the earliest she's ever gone out. She beat Daria Snigur in straight sets on Thursday, but by Saturday she knew something was wrong. "I heard there is something going on between players, that the virus is somewhere on site. I'm sure I'll be fine in a couple of days, but I had zero energy and zero stability and just felt really bad physically, and yesterday even worse," she said after the match.

The bigger picture? Swiatek has been struggling on clay. In 2025, she failed to defend her Madrid title and her Italian Open crown. She lost in the French Open semifinals. So far this spring, she hasn't won more than one match in two clay court tournaments. Before Madrid, Swiatek felt confident about her game. "I felt like I'm playing great," she said. "It's sad for me that I can't play, because I was feeling really good with my game, and I was moving forward in the process." Now she's heading home early, and the momentum she thought she had is gone.
