Australian superbrat Bernard Tomic has been fined $AUD13,300 for his outburst at a spectator duringย his first round loss in the US Open.

During his first round loss to world No.72 Samir Dzumnhur, Tomic was heard telling a spectator who was heckling him, โ€œsuck my balls,ย I will put my balls in your mouth".

โ€œYou're a peasant, I will give you some money to make you feel good,โ€ Tomic added.

It is the second biggest fine at a grand slam this year, afterย England'sย Heather Watson was finedย with $AUS16,000 fine for jamming her racquet into Wimbledon's grass courts during a second-round loss in May this year.
