Collapse of World Number One: Sinner's Dream of Career Grand Slam Crushed in Parisian Heat

World number one Jannik Sinner's bid for a career Grand Slam at Roland Garros ended abruptly due to a physical collapse in the intense Parisian heat. Sinner, who had been on an astonishing 30-match winning streak, lost to Argentina's Juan Manuel Cerundolo in the second round after winning the first two sets and leading 5-1 in the third.

The Italian's body, which had propelled him through a dominant season, suddenly failed him. Amidst stifling humidity and high temperatures, Sinner began experiencing dizziness and nausea. His shots lost their power, his movement became sluggish, and his face showed exhaustion and disbelief. After losing his serve at 5-2, Sinner sought medical attention.

American tennis legend Jim Courier criticized the situation, calling it "absolute nonsense" and "unfair to Cerundolo," attributing Sinner's issues to cramps rather than a genuine injury. Although Sinner returned to the court, he was a shadow of his former self, losing fifteen consecutive points and 17 of the last 12 games. Cerundolo seized the opportunity, completing one of the tournament's biggest comebacks with a final score of 3-6, 2-6, 7-5, 6-1, 6-1.

This loss not only ended Sinner's pursuit of the French Open title, the only Grand Slam he has yet to win, but also concluded one of the most dominant streaks in modern tennis. He had previously won all five ATP Masters 1000 tournaments in the season – Indian Wells, Miami, Monte-Carlo, Madrid, and Rome – becoming the second and youngest player, after Novak Djokovic, to achieve a "Career Golden Masters." His 30-match winning streak placed him in the company of legends like Djokovic, Roger Federer, and Rafael Nadal. Sinner's path to the title appeared open, with his main rival and defending champion Carlos Alcaraz withdrawing due to injury, making Sinner the clear favorite. However, Paris has proven to be a site of significant disappointment for Sinner, who also lost a dramatic final to Alcaraz in 2025 after holding match points.

This is absolute nonsense... It's not fair to Cerundolo. This is not an injury, these are clearly cramps.
