Opposite Cronache di Spogliatoio Sinner indicates that he is in perfect condition again. The 24-year-old Italian also knows where the remarkable collapse came from. “I think it was mental,” Sinner explains.

“You learn from these kinds of things,” continues the winner of four Grand Slam tournaments. “The fault was entirely mine. The heat and humidity got to me. Cramps are part of it, I wasn’t the only one affected.”

Valentin Vacherot succeeded Sinner last Sunday as tournament winner in Shanghai. Sinner has to go back to work on Wednesday evening. At the Six Kings Slam in Saudi Arabia, he will meet Stefanos Tsitsipas in the quarterfinals. The winner of the demonstration tournament in Riyadh will receive 6 million dollars, more than 5 million euros.

Novak Djokovic, Carlos Alcaraz, Alexander Zverev and Taylor Fritz are also participating. By participating, all players are assured of a starting amount of 1.3 million euros.
