Players competing at the Madrid Open have found themselves battling an invisible foe: a gastrointestinal virus or possible food poisoning that has already taken its toll on a number of high‑profile competitors. The situation has turned the clay courts into a battlefield not only against opponents but also against an unseen bug that is forcing withdrawals and causing on‑court distress.
One of the most talked‑about cases involved American rising star Coco Gauff. After surviving a grueling third‑set tiebreak against Linda Noskova in the round of 16, Gauff’s earlier match against Sorana Cirstea revealed how badly the illness was affecting her. During the second set of that 4‑6, 7‑5, 6‑1 win, Gauff signaled to the team’s physiotherapist, then suffered a bout of vomiting on the court.
Medical staff promptly checked her blood pressure and monitored her condition, underscoring the seriousness of the symptoms. The problem is not limited to Gauff. Tournament officials have reported a growing number of withdrawals that appear linked to the same gastrointestinal upset.
Polish star Iga Swiatek, a multiple Grand Slam champion, pulled out after describing herself as having "zero stability and zero energy" following a match against Ann Li. Swiatek’s statement hinted at severe fatigue and a lack of physical steadiness, classic signs of a stomach bug or food‑borne illness. Veteran Croatian player Marin Cilic also bowed out, citing "food poisoning" as the reason he could not face João Fonseca on Friday. His admission adds weight to the theory that something in the players’ diet may be the trigger.
Rumors circulating among the athletes point to a specific dish – shrimp tacos – as the likely source of contamination. While the exact pathogen has not been publicly identified, the consensus among players is that a shared culinary misstep is at the heart of the outbreak.
In response to the growing health scare, world No. 1 Aryna Sabalenka took a cautious approach. After dispatching Naomi Osaka in a dramatic fourth‑round comeback, Sabalenka explained that she has been adhering to a very bland, predictable diet consisting solely of chicken breast, rice, and salad.
She joked that she is deliberately avoiding the suspect tacos, saying, "I heard I have to avoid those tacos (laughing). I stick to the same food, same meal that I've been having since the very beginning of the tournament." Sabalenka’s strategy seemed to pay off.
After falling a set and a break behind Osaka, she rallied to win 6‑7 (1‑7), 6‑3, 6‑2, keeping her title defence hopes alive in the Spanish capital. Her cautious eating plan may serve as a template for other players seeking to sidestep the illness while the tournament organizers investigate the source. The broader impact of the outbreak extends beyond individual matches. Several top‑ranked players have either withdrawn or played at less than full capacity, altering the competitive landscape and opening opportunities for lower‑ranked participants.
Fans and broadcasters have also felt the ripple effects, with Sky Sports promoting its streaming service NOW as a way to catch live action despite the disruptions. The network encourages viewers to use the Sky Sports app for scores, highlights, and video content, and even advises using Chrome for the best video playback experience.
Medical experts suggest that gastrointestinal viruses spread quickly in environments where athletes share dining facilities, locker rooms, and close‑quarters travel. The combination of high‑intensity physical exertion and a compromised immune system can make players especially vulnerable. In such settings, even a single contaminated dish can ignite a chain reaction, affecting dozens of competitors.
Tournament officials have not released an official statement confirming the exact cause, but they have emphasized heightened sanitation measures, increased testing of food vendors, and the availability of medical support for anyone showing symptoms. Players are being urged to stay hydrated, monitor their health closely, and report any signs of nausea, vomiting, or abnormal fatigue immediately. For the remainder of the Madrid Open, the focus will likely shift to both maintaining competitive integrity and ensuring the health and safety of all participants.
As the tournament progresses, we may see more athletes adopting Sabalenka’s minimalist diet or opting for bland meals to reduce the risk of further illness. The situation also serves as a reminder of the importance of food safety protocols at large sporting events, where the health of athletes can directly influence the outcome of high‑stakes matches. In summary, the Madrid Open is currently grappling with a stomach‑related outbreak that appears to be linked to a specific menu item—shrimp tacos—though the exact source remains under investigation.
Prominent players such as Coco Gauff, Iga Swiatek, Marin Cilic, and Aryna Sabalenka have either suffered symptoms or altered their diets in response. The incident underscores the delicate balance between peak athletic performance and basic health considerations, and it highlights the need for vigilant food safety practices at international tournaments.
