Jannik Sinner’s French Open run ended in the second round on Thursday after Juan Manuel Cerúndolo, the world No. 56 from Argentina, fought back from a deep deficit and finished the match as Sinner faded badly in the heat. The world No. 1 had led 6-3, 6-2, 5-2 and was four points from the third round when dizziness set in and cramps began to run up his legs.
That result is the kind that gets searched immediately because Sinner was not supposed to be a quick exit in Paris. He had carried a 30-match winning streak before the loss and came into Roland Garros with a reputation for handling pressure, even after nearly running into trouble at the Australian Open in January before Novak Djokovic stopped him. Now, the top seed is out early, and the tournament is left with a result that says as much about the conditions as it does about the scoreline.
Sinner said in a news conference that he woke up not feeling very well, then tried to manage the match as temperatures at Roland Garros hovered around 90 degrees. He later described the day as warm, but not crazy warm, a judgment that sat awkwardly beside the way his body responded once the match got tight. The French Tennis Federation said those conditions were not enough to trigger the event’s heat rule, which relies on Wet Bulb Globe Temperature rather than air temperature alone and can bring 10-minute breaks between the second and third sets for women’s matches and between the third and fourth sets for men’s matches if it reaches 86 degrees, while outdoor matches are suspended at 90 degrees.
That is where the friction lives: Sinner looked fit enough to build a 6-3, 6-2, 5-2 lead, but he finished dizzy and cramped in a tournament that has not had a single heat suspension this year. He had also trained in hot weather before the BNP Paribas Open in Indian Wells and won that title in March against Daniil Medvedev on a baking hot day, which made this collapse feel less like a simple failure of preparation than a reminder that heat is still the one variable tennis in Paris has not solved. Whether the sickness that morning, the temperature, or both decided the match, the practical result is the same: Sinner leaves Roland Garros earlier than expected, and the debate over when the French Open should stop play is only getting louder.
