Wimbledon finalist Nick Kyrgios has been fined for spitting on court for the second consecutive grand slam.

The volatile Australian was given a $US10,000 ($A15,000) fine for spitting towards the crowd during his first-round match against Britain’s Paul Jubb at Wimbledon.

He again spat on the court during the third set of his second-round US Open victory over Benjamin Bonzi on Wednesday, earning a warning for unsportsmanlike conduct and a fine of $US7,500 ($A11,000).

That is the biggest fine of the tournament so far.

On the women’s side, Belinda Bencic was given a $US5,000 ($A7000) fine for racquet abuse in her first-round singles match.
