“Code violation, ball abuse. Game penalty, Nishioka,” Tourte announced. With Hurkacz now leading 4-1, both men retreated to their benches for the changeover as Goodall was left baffled.

The commentator added: “What is he doing? He’s completely lost his mind. Self-destruction if you like. I mean, he knows the rules, he knows exactly what’s going to happen.”

After sitting at his bench, Nishioka got up and skulked to the back of the baseline, finding a rogue chair behind the advertising boards and sitting down as he continued to mutter to himself. The Japanese tennis player failed to win another game for the rest of the match as Hurkacz safely reached the round of 16.
