Jannik Sinner Falls to Juan Manuel Cerúndolo in French Open Upset

The Upset at Roland Garros
Jannik Sinner, the No 1 men’s tennis player in the world, was still leading by two sets and serving for a place in the third round of the French Open when it became clear he was in significant danger on the baking clay in Paris on Thursday afternoon. He was undone in the second round of the only Grand Slam he has yet to win, not by the ingenuity of his opponent or even the immense pressure that comes with being the prohibitive favourite, but rather by his own body.
The Impact of Extreme Heat
The Italian – who had not lost a match since February – said afterward that he had been struggling with an illness. Despite waving away suggestions he had wilted in the high temperatures, the unprecedented heat wave in the first week of the French Open this year could not have helped his cause. He fell 3-6, 2-6, 7-5, 6-1, 6-1 to Juan Manuel Cerúndolo before a stunned, packed audience on Court Philippe-Chatrier.
Player Reactions to the Heat
His defeat represents one of the most shocking results in recent years. The 24-year-old had entered the court on a 30-match winning streak and earlier this month he became the only man other than Rafael Nadal, the greatest clay court player in history, to win all three clay court ATP Masters 1000 titles in the buildup to the French Open. Most players are used to disruptive weather at Roland Garros coming in the form of rain delays and damp courts, but this year in Paris the heat has changed the state of play and divided the locker room over its intensity.
The Tournament's Heat Rules
The temperature has consistently ranged between 32 and 35C most afternoons so far. Such conditions are so rare in the second Grand Slam of the year that there was significant confusion about the tournament’s heat rules at the start of the week. When asked about them on Wednesday, Novak Djokovic incorrectly thought that they did not exist: “I really don’t understand why they don’t have the heat rule,” he said. “I actually didn’t know. I thought that there is in every slam, but then someone told me that Roland Garros has no heat rule.”
Adapting to the Conditions
The actual rules are based around the tournament organisers using wet bulb sensors to monitor the temperature, and a match could be suspended when it crosses 32.2C. To date, however, no match has ever been suspended at Roland Garros due to the heat. The scorching temperatures also make a significant difference to the way matches are played on clay. Wet, damp and colder conditions make balls heavier, leading to longer rallies and a lower bounce, the hot weather hardens the court and allow the ball to fly more quickly.
