World No. 1 Jannik Sinner was eliminated from the 2026 French Open by Juan Manuel Cerúndolo in a second-round upset [1], [2], [3].
The loss represents a significant shock to the tournament bracket, as the top-seeded player exits the competition much earlier than expected. Sinner entered the event as the favorite to advance deep into the draw, but his early departure opens the field for other contenders.
The match took place on Thursday at Roland-Garros in Paris [4]. While Sinner is typically known for his composure and physical endurance, the conditions during the match proved detrimental to his performance. Reports said Sinner suffered from heat-related physical issues that impaired his ability to compete [2], [4].
These complications included cramping and dizziness, which hampered Sinner's movement and consistency on the clay courts [4], [5]. The physical toll of the heat appeared to cause a breakdown in his game, leading to a performance that deviated from his usual standard of play [3].
Cerúndolo capitalized on the World No. 1's physical struggle to secure the victory [2]. The Argentine's win marks one of the biggest upsets of the 2026 tournament, as he managed to outlast the highest-ranked player in the world during the second round [3], [6].
Sinner's exit is a rare occurrence for a player of his current ranking at a Grand Slam event. The combination of high temperatures and the grueling nature of clay-court tennis created a scenario where the top seed could not maintain his physical edge [4], [5].
