Jannik Sinner, world No 1 and favourite for this year’s French Open, suffered a dramatic second-round defeat to Argentina's Juan Manuel Cerundolo, despite leading 6-3, 6-2, 5-1.Sinner described feeling dizzy and lacking energy, although he insisted the Paris heat was not a major factor.

His 30-match winning streak ended, and for the first time since the 2023 US Open, a Grand Slam will be won by someone other than Sinner or Carlos Alcaraz, who is absent this year due to injury.

Sinner explained he had not slept well and felt unwell in the morning, and although he attempted to stay strong, his physical and mental condition declined sharply during the later sets.The loss leaves the French Open wide open, with Novak Djokovic now pursuing his 25th Grand Slam without facing his main rivals.

Meanwhile, teenage French wildcard Moise Kouame made history by reaching the third round, becoming the youngest male to do so at a Grand Slam since Rafael Nadal in 2003.Sinner confirmed he will take a break before Wimbledon to recover both physically and mentally.The match has drawn comparisons to past instances of Sinner struggling in extreme heat, highlighting a potential pattern in his game.
