Top seed Jannik Sinner's remarkable 30-match winning streak came to an unexpected end at the French Open as he lost to Juan Manuel Cerundolo in a dramatic five-set match. Sinner, who was favored to win, started strong, taking a two-set lead and leading 5-1 in the third set. However, he faced severe dehydration and dizziness due to the sweltering temperatures, which peaked above 30°C during a record heatwave in France. As Sinner's condition deteriorated, Cerundolo seized the opportunity, winning the match 3-6, 2-6, 7-5, 6-1, 6-1. This defeat marks Sinner's earliest exit from a major tournament since his second-round loss at the same event last year. Cerundolo, ranked 56th, expressed his sympathy for Sinner, acknowledging the top seed's struggle and stating, 'I feel sorry for him. He was deserving to win.' Cerundolo will next face either Martin Landaluce or Vit Kopriva in the third round.
