On June 5, 2026, Matteo Arnaldi,the 25‑year‑old Italian ranked No. 104, withdrew from the French Open men’s singles semifinal at Roland Garros after a sudden stomach illness left him vomiting and unable to eat or drink. The withdrawal forced his fellow Italian, Flavio Cobolli, to advance by walkover.

Arnaldi’s Sudden Gastrointestinal Collapse

According to the Paris‑based report, Arnaldi began feeling ill the night before the match, vomiting at 1 a.m. and again around 6 or 7 a.m. A doctor was called to his room, but the condition persisted, leaving him too weak and dizzy to step onto the court. He described the experience as “not something you wish to anybody.”

Cobolli’s Emotional Reaction and the Match’s Uncertainty

Flavio Cobolli, who was ready to play, said the news was shocking and emotionally difficult, admitting he almost cried when Arnaldi informed him. Cobolli expressed sympathy for his compatriot , lamenting the loss of what would have been a significant match. The French Open’s semifinal lineup was altered, with Cobolli advancing to the final by walkover.

Implications for Grand Slam Physical Demands

The incident underscores the physical demands of Grand Slam tournaments and the unpredictability of health setbacks. As the report notes, the sudden illness left Arnaldi unable to eat or drink without retunring to the bathroom, highlighting how even top athletes can be vulnerable to acute medical issues during high‑pressure events.

What Remains Unclear About the Illness

While the source details the timing and severity of Arnaldi’s symptoms, it does not identify the exact cause of the stomach distress or whether it was related to travel, diet, or an underlying condition. No official medical statement has been released, leaving fans and analysts to speculate about the nature of the illness.
