The Unthinkable Collapse

World number one and overwhelming tournament favorite Jannik Sinner suffered a shocking second-round defeat at Roland-Garros on Thursday, losing to Argentina's Juan Manuel Cerundolo. The Italian, who was on a 30-match winning streak, appeared to be cruising to victory after taking the first two sets 6-3, 6-2 and leading 5-1 in the third. However, in searing heat on Court Philippe-Chatrier, the 24-year-old's body began to fail him. He lost the next three games and, serving at 5-4 down 0/40, left the court for a medical timeout.

“I don't know what's wrong with me. I might be dehydrated.”

The break did not restore his energy. Cerundolo, the world number 56, seized the moment to complete a remarkable 3-6, 2-6, 7-5, 6-1, 6-1 comeback victory. Sinner later explained he had felt unwell since waking up, with dizziness and a lack of energy, and appeared to be suffering from a hip issue. The defeat ended his record streak of 30 consecutive wins and his first loss in three months.

Medical Timeout Controversy

The match was not without controversy. Former world number one Jim Courier was furious that Sinner was allowed to receive treatment for what appeared to be cramps without penalty. Under the rules, cramping is not considered an injury that warrants a medical timeout.

“It's unfair to Cerundolo. The clock should keep running, he should be penalized for this. It's not an injury. He's reacting to different parts of his body, it's not like an ankle injury. These are clearly cramps.”

Courier argued that the rules are being bent for top players, calling the decision to take Sinner off court to check his vital signs "complete nonsense." The incident has reignited debate about the consistent application of medical timeout regulations in professional tennis.

Heatwave Hits Roland-Garros

The extreme heat in Paris has been a major factor throughout the tournament. Sinner's collapse was the most dramatic consequence, but other incidents have raised concerns. Norway's Casper Ruud appeared close to fainting on his bench after three hours of play and required a doctor's examination before being allowed to continue. A young ball girl also suffered a medical episode that forced the interruption of another match. Spectators in the alleys described the conditions as brutal.

“Is it ideal to play until midnight or later? No. But in the case of a heatwave, maybe we need to think about it.”

Novak Djokovic, a three-time Roland-Garros champion, suggested that matches should be postponed to the evening to avoid the peak heat. Current regulations allow for a match to be interrupted for 10 minutes or more at the request of a player or umpire, but only if certain thresholds for temperature, humidity, and wind are exceeded.

A Wide-Open Tournament

The elimination of the world number one, who was the clear favorite in the absence of injured double defending champion Carlos Alcaraz, has completely reshuffled the men's draw. Among the 32 players remaining in the third round, only one former champion is left: Novak Djokovic, who at 39 is chasing a record 25th Grand Slam title. The path is now clear for players like Alexander Zverev, who is seeking his first major, and young talents such as Ben Shelton, Joao Fonseca, and Rafal Jodar.

French Hopes Soar

While the tournament lost its top seed, French tennis found a new hero. Seventeen-year-old Moïse Kouame, playing in his first Roland-Garros and only his second Grand Slam match, advanced to the third round after a nearly five-hour battle against Paraguay's Adolfo Daniel Vallejo. Kouame won 6-3, 7-5, 3-6, 2-6, 7-6 [10-8], saving a 5-2 deficit in the final set and thrilling the crowd on Court Suzanne-Lenglen. Diane Parry also secured a victory, making it a positive day for the home nation.
