World No. 1 Jannik Sinner was eliminated from the 2026 French Open in a second-round upset on Thursday [1], [5].

The loss marks a significant disruption to the tournament bracket and the top seed's trajectory, as Sinner entered the event as the favorite to win the title.

Sinner fell to Argentine Juan Manuel Cerúndolo, who is ranked 56th in the world [2]. The match, played on Court Philippe-Chatrier in Paris, lasted five sets [1], [4].

Reports indicate that Sinner struggled throughout the match with searing heat [1], [4]. The extreme weather conditions sapped his energy and eventually led to a physical collapse [1], [3].

This physical decline became evident in the closing stages of the match. Sinner won only two of the final 20 games [4], allowing Cerúndolo to secure the victory and advance in the tournament.

The upset occurred on May 28, 2026 [1], [5], sending shockwaves through the Roland-Garros crowd as one of the most dominant players in current tennis was ousted early in the competition.

The early exit of the world's top-ranked player opens the draw significantly, removing a primary contender and creating a power vacuum in the men's singles bracket. Sinner's struggle with the heat also highlights the increasing impact of extreme weather on athlete performance during Grand Slam events.
