Jannik Sinner’s dramatic French Open defeat on Thursday quickly became about far more than tennis after the world No. 1 physically broke down in extreme Paris heat during a match he appeared certain to win.
Facing Juan Manuel Cerúndolo, Sinner looked completely in control early on.
The Italian raced into a 6-3, 6-2, 5-1 lead and was just one game away from victory before his body suddenly began to fail him.
Under temperatures that reportedly climbed above 33°C at Roland Garros, Sinner started struggling with cramps, dizziness and exhaustion.
Cameras repeatedly showed him bending over between points, placing ice towels around his neck and trying to cool himself with handheld fans during changeovers.
At one stage, Sinner admitted:
“I couldn’t move anymore. My legs were completely blocked.”
The collapse stunned spectators because he had dominated the opening stages with his usual relentless baseline intensity.
But as the heat intensified, his movement sharply declined and Cerúndolo slowly took control of the match.
After the defeat, however, Sinner insisted the issue was more complicated than simply struggling with the weather.
“It wasn’t only the heat,” he explained. “I already felt bad this morning.”
He also revealed he had been dealing with physical discomfort before stepping onto court.
“I was dizzy. I wasn’t feeling well physically,” Sinner said during his press conference.

Analysts pointed to the brutal conditions and Sinner’s physically demanding style of play as major contributing factors.
His game depends heavily on explosive movement, long baseline exchanges and constant directional changes, a combination that becomes increasingly difficult under intense heat stress and dehydration.
The defeat also ended Sinner’s 30-match winning streak, making the collapse even more shocking within the tennis world.
