No player had arrived at Roland Garros carrying such overwhelming expectations since Rafael Nadal dominated the French Open with a record 14 titles.
Jannik Sinner had been virtually untouchable over the previous three months, collecting five consecutive Masters 1000 titles, including three on clay, while putting together a 30-match winning streak.
With his fiercest rival, Carlos Alcaraz, sidelined by a right wrist injury, the path appeared clear for Sinner to lift the Coupe des Mousquetaires and complete a career Grand Slam.
That is what made Thursday’s collapse in the sweltering Paris heat so shocking. Sinner stood just one game away from sealing his second-round match in straight sets while leading 5-1 in the third set, only for everything to suddenly unravel.
The top-ranked Sinner struggled with dizziness and was beaten by 56th-ranked Juan Manuel Cerundolo 3-6, 2-6, 7-5, 6-1, 6-1 after wasting two opportunities to serve for the match.
“I didn’t feel very well on court,” Sinner said. “I struggled, starting to feel very dizzy, very low on energy. ... In the beginning, I was hitting very clean, very good, and then I just kind of hit the wall.
“I didn’t have energy, really. I was very, very flat. The whole body. I don’t remember the last time I felt this weak,” Sinner added.
Sinner said that when he woke up Thursday, he “didn’t feel very well.”
Sinner bent over on the clay court in apparent exhaustion multiple times and was hardly even running for shots as the match wore on, resorting to drop shots and serve-and-volley tactics to try to shorten the points.
He attempted to cool himself with a hand-held fan on changeovers and put bags of ice around his neck.
The temperature at the start of the match was 29 degrees Celsius (84 Fahrenheit) and rose to 32 C (90 F).
“It was warm but not crazy warm,” Sinner said. “I feel like it was quite OK to play. Really it was nothing against the heat, nothing against the weather. It was just me today, but it happens.”
Cerundolo did not celebrate too much when it was over, just producing a little wave to the crowd.
“It’s tough for him,” Cerundolo said. “I couldn’t win more than three games per set. So I think I was a little bit lucky. ... He deserved to win this match. But then I don’t know what happened. ... I feel sorry for him and hope he recovers.”
When Sinner served for the match a second time at 5-4 in the third set, he bent over at 0-40 and then walked to his chair. He asked for assistance and left the court. His entire light blue outfit was soaked through with sweat.
After losing the set 7-5, Sinner received medical attention and left the court. Minerals were added to his drink when he returned, but Sinner was not able to recover.
Sinner lost 18 of the last 20 games. Asked if he considered retiring before the match ended, Sinner said that in the “fifth set we all know everything can happen. I was in a tough spot.”
Sinner’s previous loss came Feb. 19 in the Qatar Open quarterfinals. He had won five straight Masters 1000 titles while dropping just three sets.
“We’ll definitely do some tests to be sure of what happened today,” he said.
“Let’s hope we’re ready for Wimbledon,” Sinner added. “To be ready there, we need to recover well and do things right now.”
But Sinner has a history of struggling in the heat. He admitted he was lucky at the Australian Open in January against Eliot Spizzirri when the roof was closed and the third-round match swung his way. He also retired from a match in Shanghai in October that was contested in extreme humidity.
“Shanghai was very tough. Humidity very high. Australia was very, very warm,” Sinner said. “Here, I mean it was warm, but it was OK. It was not like I was dying because of the heat. I think today was a completely different scenario.”
“It’s tough to accept, of course, because of the position where I’ve been and everything considered,” added Sinner, who sportsbooks had listed at around minus-300 to win the tournament.
On the same Court Philippe-Chatrier last year, Sinner wasted three match points against Alcaraz and lost an epic final.
In other matches, 17-year-old Frenchman Moise Kouame became the youngest man to reach the third round of a Grand Slam since Nadal, also 17, at Wimbledon in 2003. Kouame beat Adolfo Daniel Vallejo 6-3, 7-5, 3-6, 2-6, 7-6 (8).
Felix Auger-Aliassime, at No. 4 the highest-seeded player left in the top half of the draw after Sinner’s exit, beat Roman Andres Burruchaga 4-6, 6-0, 7-5, 6-1.
Fifth-seeded Ben Shelton was upset by 62nd-ranked Belgian Raphael Collignon 6-4, 7-5, 6-4, and Frances Tiafoe required nearly five hours to overcome Hubert Hurkacz 6-7 (5), 7-6 (5), 6-4, 6-7 (1), 6-4.
Also, Cerundolo’s older brother, Francisco, beat Hugo Gaston 2-6, 6-4, 6-2, 6-1.
In women’s action, Naomi Osaka put on another fashion show for her walk-on before beating Donna Vekic 7-6 (1), 6-4.
Defending champion Coco Gauff beat Mayar Sherif 6-3, 6-2, and top-ranked Aryna Sabalenka, last year’s runner-up, defeated Elsa Jacquemot 7-5, 6-2.
