Jannik Sinner leaves the field: what happened

Foul at Roland Garros: Jannik Sinner was forced off the court in the third set of his match against Juan Manuel Cerundolo, valid for the second round of the Paris Slam.
The world number one was quietly leading 2 sets to nil and 5-1 in the third set, when he suddenly froze, perhaps due to the great heat. The San Candido champion began to feel the Paris heatwave (perceived temperature 36 degrees), and he resoundingly lost the next three games. On 5-4 for him, 0-40 for Cerundolo, he called for the physiotherapist’s intervention: “I don’t feel well, I feel that I need to vomit.”
The South Tyrolean continued to touch his thigh and then left the court in search of refreshment. After a few minutes, he re-entered the field and resumed the game.
