World No. 1 Jannik Sinner suffered a stunning defeat at the French Open on June 1, squandering a commanding lead against Juan Manuel Cerúndolo. The Italian dropped 11 of the last 12 games to lose 6-3, 6-2, 5-7, 1-6, 1-6 after leading 6-3, 6-2, 5-1.
Sinner, who was four points from the third round, attributed the loss to illness and poor sleep rather than the 32-33°C heat in Paris. He noted the conditions differed from tougher prior events in Shanghai and Australia.
