Aussie tennis star Nick Kyrgios risks four-week ban after being slapped with $1500 fine

Australia's Nick Kyrgios has been slapped with a $1500 fine for a foul-mouthed outburst at the Shanghai Masters, pushing him closer to a potential four-week ban.

Kyrgios was fined for an audible obscenity during his win over Andreas Haider-Maurer, when he was also heard calling the tournament a "circus" and complaining about the ball kids, according to reports.

The 20-year-old could trigger a 28-day ban if he incurs $5000 in fines before February, after he was given a suspended ban in August for his controversial insult against Stan Wawrinka.

Kyrgios received his second code violation in a week on Monday when he slammed the "f***ing surface" at the Shanghai venue.

He is skating on thin ice, after incurring the suspended ban for making a sexual comment about Wawrinka's girlfriend during their match in August at the Rogers Cup in Canada.

Following Monday's match, he maintained conditions were crazy at the Shanghai complex's grandstand court, where a cameraman was ejected for repeatedly talking during points.

"They were talking in the middle of the points. I was just expecting a lot more obviously from a Masters event," Kyrgios said.

"You're not going to see Roger (Federer) or Rafa (Rafael Nadal) playing on a court like that. They're always playing on centre court where things usually go pretty smoothly," he added.

"They're not going to have the cameraman talking in the middle of the point on centre court."

Things went more smoothly for Kyrgios and doubles partner Bernard Tomic yesterday as they beat Vasek Pospisil and Jack Sock to reach the second round.
