Known for his poor behaviour on court, Australia's Nick Kyrgios was fined for an audible obscenity during an argument with the chair umpire
With his sight set on the world number one spot, Andy Murray moved fluently past America's Steve Johnson 6-3, 6-2 to reach the third round at the Shanghai Masters on Wednesday.
It was a different story for Spanish great Rafael Nadal who crashed to a shock defeat to Viktor Troicki in the first round. The 14-time Grand Slam champion lost 6-3, 7-6 (7/3) as he suffered his first ever defeat to the Serb.
Afterwards, Nadal, now 30 and with a catalogue of injuries to his name, vowed to return to top form in next season. "I know what I have to do and I'm going to do it," scowled the Spaniard, who has had little to smile about at the big tournaments this year.
"I've got two-and-a-half months until next season starts so I have got two-and-a-half months to put myself at the level I want to be. And I'm confident I'm going to do it."
Australia's Nick Kyrgios too melted down in spectacular fashion. The hot-headed world number 14 was slapped with a code violation after an altercation with the chair umpire and a heckler. He also got a warning to play properly after he patted a child-like serve into his opponent's court.
Booed off the court, Kyrgios admitted not trying after he lost 6-3, 6-1 to German qualifier Mischa Zverev, the world number 110. Kyrgios added: "I'm good at hitting a tennis ball at the net. Like, big deal. I don't owe them anything. It's my choice," he said. "If you don't like it, I didn't ask you to come watch. Just leave. If you're so good at giving advice and so good at tennis, why aren't you as good as me? Why aren't you on the tour?"
Known for his poor behaviour on court, Kyrgios had even received a one-month suspension last year for making a lewd and personal comment during a match with Stan Wawrinka.
