This was the conversation with which Sinner convinced the umpire to stop the match due to rain

While Jannik Sinner and Daniil Medvedev were playing the third set of the ATP Rome semifinals, the rain, which hadn't stopped in these two weeks, made an appearance. However, despite falling heavily, the match continued until the Italian asked the umpire, Aurelie Tourte, to stop the game. The Frenchwoman decided to continue the match, and the Russian also wanted to continue, until the world number one said, "It's raining buckets! What do you mean? But what do you mean? The problem is the lines, what if I slip on the lines? I can make a decision, but it's raining buckets!" After this argument, Tourte changed her mind and announced the suspension of the match until further notice.
