Shanghai: Nick Kyrgios has continued his flirtation with the suspended six-month ban issued by the ATP, having received his second code violation warning in a week – this one for an audible obscenity during a colourful, almost-farcical, winning debut at the Shanghai Masters on Monday.

Kyrgios' frustrations percolated from early in the 6-3, 6-2 opening round defeat of Austrian Andreas Haider-Maurer that he branded "a circus" and "unbelievable", declaring "I hate this place" during a running commentary that bounced around the near-empty Grandstand court at Qi Zhong Tennis Centre.

A cameraman was ejected after multiple warnings for talking on the side of the court during points, there were issues with ball-kids, noisy commentary audio could be heard in the early stages and Kyrgios several times struggled with his footing behind the baseline.

It was the latter issue that eventually led to the warning from chair umpire Carlos Bernardes in the second game of the second set, when the world No.32 had run to attempt a forehand winner down the line on break point, and blamed the "f ... ing surface" he had also criticised in set one. Haider-Maurer's complaints were generally less audible but still apparent; the world No.60's biggest statement was to belt a ball out of the stadium to earn a code violation of his own.
