WATCH: Nick Kyrgios risks fine after bizarre Shanghai Masters exit

"Nick, you can't play like that, okay?... It is just not professional."

Australian Nick Kyrgios crashed out of the Shanghai Masters and appeared to give up during a 6-3 6-1 defeat to qualifier Mischa Zverev.

Kyrgios, 21, had said he was "bored" after a first-round victory over Sam Querrey, which followed a run to the Japan Open title last week.
