The Madrid Open has been plagued by an unexpected adversary this week: a gastrointestinal illness that appears to be sweeping through the player field. While the tournament usually showcases high‑octane rallies and precision serving, many of the sport's top competitors have been forced to confront a far less glamorous opponent – a stomach virus or possible food poisoning that has left several stars feeling ill and, in some cases, withdrawing from their matches.
One of the most high‑profile cases involved 19‑year‑old sensation Coco Gauff. After dispatching Sorana Cirstea in the third round with a hard‑fought 4‑6, 7‑5, 6‑1 victory, Gauff’s triumph was marred by visible signs of distress.
During the second set she signaled for a physiotherapist, and shortly thereafter she experienced a bout of vomiting on court. Medical staff quickly intervened, checking her blood pressure and monitoring her condition.
Despite the setback, Gauff managed to rally and secure the win, but the episode highlighted how the illness is affecting even the most resilient athletes. The problem is not limited to Gauff. Several other high‑ranking players have either withdrawn or retired from matches, citing similar symptoms.
Six‑time Grand Slam champion Iga Swiatek pulled out of her contest against Ann Li, describing herself as having "zero stability and zero energy" after a sudden collapse on the court. Veteran Croat Marin Cilic also withdrew before his scheduled match with Joao Fonseca, attributing his absence to "food poisoning" that left him unable to compete. Madison Keys, another top‑seed, has also been listed among those who have pulled out of the event due to the same mysterious ailment. Rumors have been swirling among the players and the media about the source of the outbreak.
A popular theory points to a particular culinary item that has been served at the tournament’s hospitality venues – shrimp tacos. While no official investigation has confirmed this link, many athletes have taken note of the speculation and have begun to adjust their diets accordingly.
World No. 1 Aryna Sabalenka, fresh off a dramatic fourth‑round win over Naomi Osaka, openly discussed her dietary precautions.
After defeating Osaka in a three‑set battle that saw her come back from a set and a break down to win 6‑7 (1‑7), 6‑3, 6‑2, Sabalenka said she has been sticking to a very plain and simple regimen consisting of chicken breast, rice, and salad. She joked that she had heard she needed to avoid the infamous tacos, adding, "I stick to the same food, same meal that I've been having since the very beginning of the tournament. So far, so good." Sabalenka’s approach underscores a broader trend among players who are now prioritizing bland, easily digestible foods in an effort to avoid aggravating any potential stomach issues. The shift away from richer, spicier fare reflects a pragmatic response to the uncertainty surrounding the outbreak.
While some athletes have opted for complete fasting or even temporary elimination of all solid foods, most are choosing a middle ground: meals that are low in fat, low in spice, and high in protein and carbohydrates to maintain energy levels without risking further gastrointestinal upset. The tournament organizers have been working behind the scenes to identify the source of the illness. Officials have increased sanitation measures in locker rooms, dining areas, and public spaces, and they are conducting thorough inspections of the food vendors operating on site.
In addition, they have issued advisories urging players to stay hydrated, wash their hands frequently, and be cautious about what they eat and drink during the competition. Beyond the immediate health concerns, the outbreak has had a noticeable impact on the competitive landscape of the Madrid Open. With several top seeds out of contention, the draw has opened up for lower‑ranked players to make deeper runs than they might have otherwise.
This has added an element of unpredictability to the tournament, as fans watch emerging talents seize the opportunity to advance further in a high‑profile event. From a broader perspective, the situation serves as a reminder of how external factors – such as food safety and public health – can influence professional sports. While athletes train rigorously to perfect their technique and conditioning, they remain vulnerable to everyday hazards that can derail even the most meticulously planned campaigns.
The Madrid Open episode may prompt other tournaments to re‑evaluate their catering practices and implement more stringent health protocols to protect participants. In summary, the Madrid Open is currently grappling with a stomach virus or food‑borne illness that has sidelined notable players like Iga Swiatek, Marin Cilic, and Madison Keys, while also affecting Coco Gauff and prompting Aryna Sabalenka to adopt a minimalist diet. The speculation surrounding shrimp tacos adds a colorful anecdote to the unfolding drama, but the primary focus remains on player health and tournament integrity.
As the event continues, officials are intensifying their efforts to pinpoint the cause, enforce stricter hygiene standards, and ensure that the remaining matches can proceed safely. Fans can still enjoy high‑quality tennis, with live coverage available on Sky Sports, the NOW streaming platform, and the Sky Sports app, which promises expanded access to live sport throughout the season.
