Italian Jannik Sinner, tennis world No. 1, suffered a shocking second-round defeat in the French Open on May 28 against world No. 56, Juan Manuel Cerundolo of Argentina.
The 6-3, 6-2, 5-7, 1-6, 1-6 loss came after a heatwave came over Court Philippe-Chatrier in Paris, and Sinner appeared to be struggling physically, though he didn’t blame the heat after the match.
