Matteo Arnaldi withdrew from his French Open semifinal match on Friday, June 5, 2026 [1], due to a viral illness [2].

The withdrawal creates a significant shift in the tournament bracket, granting fellow Italian Flavio Cobolli a walk-over into the championship match. This marks a rare instance of a semifinalist exiting a Grand Slam due to health issues on the eve of the final.

Arnaldi was unable to compete at Roland-Garros in Paris after suffering from a virus [3]. The illness left the player vomiting and sleep-deprived, making it physically impossible for him to take the court [4].

Flavio Cobolli, currently ranked No. 10 [5], now advances to the final. He will face Alexander Zverev, who holds the No. 2 ranking [6]. The match represents a high-stakes clash between a rising Italian star and one of the tour's most consistent top-tier players.

This incident is a rare occurrence in modern Grand Slam history. It is the first time a player has withdrawn from a Grand Slam semifinal due to illness since 2022, when Rafael Nadal withdrew from the Wimbledon semifinal [7].

Arnaldi's departure leaves the tournament without a semifinal match between the two Italians, a matchup that had generated significant interest for the home crowd and international fans alike. The focus now shifts to Cobolli's ability to capitalize on the unexpected path to the title.

The withdrawal of Arnaldi removes a primary contender from the tournament and provides Flavio Cobolli with a critical physical and mental advantage. By avoiding a grueling semifinal match, Cobolli enters the final with full energy reserves to face the world No. 2, Alexander Zverev, potentially altering the outcome of the championship.
