Frances Tiafoe lost his temper and scolded the referee during a tennis tournament in Shanghai.
Damn it, you've ruined the match. Bloody good job, the American was heard shouting.
A behavior that is now being fined.
The 26-year-old is forced to pay nearly two million kronor for the outburst.
Tiafoe, who is 18th on the ATP world ranking, has later apologized and called his behavior unacceptable.
What do you think?
