Tomic the terror dishes out a tongue-lashing to US Open heckler during first round exit

Fiery Australian star Bernard Tomic was at the centre of a foul-mouthed US Open controversy on Tuesday when he became embroiled in a lewd exchange with a heckler.

The 23-year-old slumped to a 6-4, 6-3, 4-6, 7-6 (7-0) loss to Damir Dzumhur of Bosnia on the old Grandstand court.

But before he lost the first round match, he also spectacularly misplaced his composure, angrily hitting back at a spectator he accused of deliberately trying to get under his skin.

Courtside microphones picked up Tomic telling the fan: “I will put my balls in your mouth” followed moments later by “I will give you some money to make you feel good”.

Tomic apologised for the incident, suggesting his Croatian roots may have been a factor in the clash against his Bosnian opponent.
