Jannik Sinner, the top-seeded player and a strong favorite for the French Open title, suffered a surprising defeat in the second round against Juan Manuel Cerundolo, ranked 56th, with a scoreline of 3-6, 2-6, 7-5, 6-1, 6-1. The match took place in sweltering conditions, with temperatures soaring to 32 degrees Celsius (90 degrees Fahrenheit), which severely affected Sinner's performance. Despite starting strong and even serving for the match at 5-4 in the third set, he collapsed from exhaustion and required medical attention. Sinner's loss ends a remarkable 30-match winning streak that began in February and highlights the challenges he faced in extreme heat, reminiscent of his earlier struggles at the Australian Open. This early exit is particularly disappointing as Sinner aimed to claim his first Grand Slam title, especially with reigning champion Carlos Alcaraz absent due to injury.
