Videos - Tiafoe goes off the rails in Shanghai: "Fuck you!"

Frances Tiafoe was trapped this Tuesday.

Up against Roman Safiullin, ranked 61st in the world and Bublik's winner in the previous round, the American was defeated after more than 3 hours of a crazy battle (5-7, 7-5, 7-6).

The most memorable moment of the match, however, was Tiafoe's reaction.

During the tie-break of the final set, the world number 17 was cautioned several times for going over time, losing his first service point at 5-5.

After losing the last two points and thus the match, he totally lost his nerve, directly insulting the referee (see video below).
