Top seed Jannik Sinner suffered a stunning second-round exit at the French Open, collapsing from a commanding position against Juan Manuel Cerundolo. After winning the first two sets and holding a 5-1 lead in the third, Sinner dropped 18 of the final 20 games. His movement became severely restricted, and he was seen limping and frequently leaning over courtside.

While Sinner cited poor sleep and a general lack of energy, the sweltering Paris heat was an undeniable factor. Temperatures soared, and despite not meeting the official criteria for a heat rule suspension, the conditions clearly impacted the Italian, who had previously cramped in similar weather. This marks the earliest exit for a top-seeded man at Roland Garros since Andre Agassi in 2000.

This unexpected defeat ends Sinner's remarkable winning streak and significantly opens up the draw. With both Sinner and Alcaraz now out, it's the first time since 2000 that neither of the top two players reached the third round. The path is now considerably clearer for contenders like Novak Djokovic to pursue a record 25th Grand Slam title.
