Kyrgios has been fined a total of $US16,500 ($A21,800) for breaches of the ATP code of conduct during his second-round match against Mischa Zverev on Wednesday.

The controversial world No.14 received a code violation for an audible obscenity during the 6-3 6-1 capitulation and later admitted he took the easy way out.

Kyrgios said yesterday there was no excuse for his meltdown, admitting he “took the easy way out”.

His behavior – including limply tapping one serve over the net and then walking off court before Zverev had even struck his return – sparked outrage across social media
