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.
