It has been two weeks since the biggest surprise at Roland Garros unfolded: the elimination of Jannik Sinner in the second round against Juan Manuel Cerúndolo, after physically collapsing due to the heat when he was leading 6-3, 6-2, 5-1, and ended up defeated in five sets winning only two more games. It was the story of the tournament, and it is still resonating.
Above all, what raises the most doubts is the world number one's resistance to the sun. It was evident at the Australian Open, where the heat rule saved him from disaster against Eliot Spizzirri; he also succumbed within 20 minutes in the Cincinnati final against Carlos Alcaraz, although that time he claimed to have had a fever since the day before. But in his match against the younger Cerúndolo brother, in a scorching Phillipe Chatrier, his body couldn't take it anymore.

What happened to Jannik Sinner in his collapse at Roland Garros 2026?
Something that is beginning to worry the tennis world, considering that 80% of the tournaments are played outdoors in hours where the heat always takes its toll. However, Kim Clijsters, former world number one and winner of four Grand Slams, believes that Sinner's elimination at Roland Garros was also due to the mental aspect.
She stated on the Love All podcast: "It was very confusing. He was seen grabbing the upper part of his left leg, his buttock, does he have cramps? Did he suffer a muscle tear? Is it related to an injury? We don't know, and basically, we are just speculating," the Belgian emphasized.
Until she pointed out a more than likely factor: "I think anxiety played a significant role in his elimination at Roland Garros. The fact that he finished the match and didn't give up victory demonstrates the respect he has earned. Probably, 99 out of 100 players would have retired after losing that third set. It's interesting to see. He is undergoing a lot of analysis, but the mental aspect will also play a major role in this situation."

Also, Sinner's physical build doesn't help him withstand the strong heat waves: "He's strong, but also thin; he doesn't have a lot of muscle mass, you know, when he gets a bit sick, how much reserve energy does he have? How much strength does he have to say, 'Okay, I'm strong enough to keep fighting'?"
In fact, Sinner has undergone tests in Milan before heading to Wimbledon to see if he has any anomalies or if his defeat was due to a series of circumstances. But no matter what, the world number one will need to find a solution to a situation that has recurred over time and that could happen again sooner rather than later.
