Coco Gauff managed to push through a bout of nausea and even vomit on the court, yet still emerged victorious over Sorana Cirstea in a lively encounter at the Mutua Madrid Open on Sunday. The American, who entered the tournament as the defending French Open champion and was runner‑up in Madrid exactly one year earlier, battled through physical discomfort, clawing back from a set down and a break in the second set to secure her place in the fourth round with a 4‑6, 7‑5, 6‑1 triumph in Spain’s capital.

Early in the second set Gauff signaled that she needed medical attention. She called for the tournament physiotherapist, and moments later she was seen vomiting on the hard‑court surface.

After the episode, a doctor performed a quick blood‑pressure check to ensure she was stable enough to continue. The incident underscored the growing concerns surrounding a viral illness that has already forced several high‑profile players out of the event, including Iga Swiatek, Marin Cilic and Madison Keys. When asked how she managed to keep fighting, Gauff admitted she was largely in survival mode. "I don't know.

Honestly, I was just trying to finish the match and one point turned into another," she told reporters. "I think I got what everybody else is having here in Madrid, unfortunately. Just going try to push through for tomorrow." Later, in a conversation with Sky Sports, she elaborated on the physical toll. "I don't know how I got it done.

I tried to keep my food down but once I threw up I was able to throw up again and then I felt a bit better," she said. "It was a tough match. I think I got the Madrid Open virus bug that's going around and I'm usually someone who doesn't get sick." Gauff also reflected on how the clay surface influenced the match.

"The clay helped me today because the ball was a little bit slower so it bounced higher. It gave me time to get to some balls when I wasn't moving my best," she explained, noting that the slower conditions gave her a marginal edge while she was still recovering from the upset.

The Romanian opponent, Sorana Cirstea, grew frustrated not only with the pace of play but also with what she perceived as coaching from Gauff’s box. About halfway through the first set, Cirstea approached umpire Kader Nouni and complained, "Her coach is screaming from that end, 'Come on, aggressive, let's go, do this all game long, come on, forehand, backhand, first serve', this is coaching! Because I'm there and they are bothering me because they are screaming in my ear." The umpire responded, "For me, I do not hear any coaching," effectively dismissing the claim. Despite the tension and the physical setback, Gauff steadied herself, tightened her grip on the racket, and turned the tide in the third set.

After a tightly contested second set that she clinched 7‑5, she surged ahead with a dominant 6‑1 finish, showcasing her resilience and tactical adaptability on clay. With the win, Gauff now looks ahead to a quarter‑final clash with Linda Noskova.

Noskova advanced to the next round after a walk‑over when 20th‑seeded Liudmila Samsonova withdrew because of illness, setting up another intriguing matchup on the red dirt. The broader tournament narrative continues to be shaped by the mysterious virus that has disrupted the draws of several top players. Organizers have been monitoring the situation closely, implementing health checks and advising players to stay hydrated and rested. While the exact nature of the illness remains unclear, its impact on the competition has been palpable, prompting heightened caution among participants and staff alike.
