Aussie Nick Kyrgios is through to the second round at Wimbledon, but not without controversy once again.

Kyrgios defeated Czech veteran Radek Stepanek 6-4, 6-3, 6-7, 6-1 in a near perfect first round match.

However, the talking point will once be talking about Kyrgios' exchange with umpire Mohamed Lahyani.

Lahyani gave Kyrgios a code violation for unsportsmanlike conduct for swearing after losing the third set.

Kyrgios then questioned the code violation and demanded an explanation, also claiming double standards.

“What did I do?” Kyrgios said.

“What did I say. I want to know what I said?”

“You know what you said. I’m not going to repeat it,” Lahyani said.

The 21-year-old then continued the argument at the following change of ends.

“Every single person that has said that word in this chair has got a code violated. You telling me that?”

But, the exchange did not fluster the young Australian, who rallied to take the fourth set 6-1 and book a second round match-up with German wildcard Dustin brown.

Meanwhile, fellow Aussie Bernard Tomic is locked at two sets all with Spaniard Fernando Verdasco, with the match to resume on Wednesday.
