Nick Kyrgios admits he’s copped what he deserved for his infamous sledging of French Open champion Stan Wawrinka.

Kyrgios will be walking a fine line for the next six months after the ATP slapped a 28-day suspended ban on the young tennis player.

But in his first extended interview since also being slugged last week with a suspended fine of $US25,000 ($A34,900) for “aggravated behaviour”, a more contrite Kyrgios conceded he needed sanctioning.

“I think it’s fair. I deserved to be punished to some extent and obviously I’m still young,” Kyrgios said ahead of his blockbuster first-round US Open showdown with Andy Murray.

“They’ve given me the impression that they are going to start locking down on that sort of stuff so I’ve definitely learnt my lesson.”

Both sanctions will be waived if Kyrgios avoids any fines for verbal or physical abuse or doesn’t accumulate fines totalling more than $US5000 at ATP events before 24 February.

“So I obviously know I’ve got to keep everything in order and obviously be on my best behaviour out there,” said Australia’s two-time Grand Slam quarterfinalist.

“But at the same time I’m not going to go out there and not show any emotions at all. I think I’m going to go out there and just back myself.

“It’s going to be fine. If I have a lot of positive energy going out there, I think I’ll be fine.”

Kyrgios is playing doubles with Thanasi Kokkinakis in New York and has also leaned heavily on Davis Cup teammate Lleyton Hewitt after spending several days training with Lleyton Hewitt at the former world No.1’s Bahamas base last week.

“That’s been massive, to have his support on the court and off the court,” he said.

“Whenever I’ve needed to talk to him, he’s been there. He’s taken time out for me, to spend time with myself and help Thanasi when he can as well, so I feel he’s been a massive influence.”
