Jannik Sinner's French Open defeat was latest in series of issues with heat and cramps‎

Two days after Jannik Sinner’s shocking meltdown at the French Open, it’s still unclear what exactly the issue was that led to him wasting a seemingly insurmountable advantage in his second-round match. What is clear, though, is that the top-ranked player has had a series of issues with heat and cramps in big matches throughout his career. Sinner said after wasting a two-set and 5-1 advantage in his five-set loss to Juan Manuel Cerundolo that he didn’t feel well when he woke up the morning of Thursday’s match.
