Jannik Sinner Falls to Cerúndolo in French Open Bracket Second Round

Jannik Sinner is out of the french open bracket after Juan Manuel Cerúndolo beat the world No. 1 in the second round on Thursday, ending a 30-match winning streak in Paris. Sinner had led 6-3, 6-2, 5-2 before his play unravelled in around 90-degree heat.

Sinner’s Lead Vanished

He had the match under control through two sets and the opening games of the third, then his level dropped sharply as the temperature climbed. Cerúndolo, ranked No. 56, kept applying pressure and finished the upset once Sinner could no longer hold the advantage.

Sinner said after the match that he woke up not feeling very well. He also said, "It was warm, but not crazy warm," a line that matched the way he described the physical struggle he faced on court.

Heat Rule Stayed Idle

Roland Garros was playing in temperatures around 90 degrees, but the French Open heat rule was not engaged at that level. Under the rule, matches can get 10-minute breaks between sets in certain cases once the Wet Bulb Globe Temperature reaches 86 degrees or higher, while outdoor matches are suspended if the temperature hits 90 degrees.

There have been no suspensions at the French Open this year. Sinner had trained in hot weather before winning the BNP Paribas Open in Indian Wells in March, which makes this loss harder to dismiss as a simple weather excuse.

What Cerúndolo Leaves Behind

The result sends Cerúndolo into the third round and removes the top seed early, a jolt for a tournament already under heat stress. Sinner’s own history adds to the reading of the match: he had nearly lost at the Australian Open in January before Novak Djokovic beat him, and the Paris defeat again came after conditions changed the shape of his contest.

For the rest of the field, the bracket has opened and the temperature question is still attached to the event. Paris now has one fewer favorite and one more reminder that the pace of the game is colliding with the heat on the clay.
