Kyrgios: 'I'll quit if I win the US Open'

It is perhaps unlikely the comment should be taken too seriously. Kyrgios, no stranger to controversy on and off the court, offered several other sarcastic or dismissive responses to questions.

Australian tennis player Nick Kyrgios conducted an impromptu Q&A session on Twitter ahead of his meeting with Britain's Aljaz Bedene in the first round at Flushing Meadows on Tuesday.

Outspoken Australian Nick Kyrgios has suggested he will quit tennis if he wins the US Open.

The World No. 16 conducted an impromptu Q&A session on Twitter ahead of his meeting with Britain's Aljaz Bedene in the first round at Flushing Meadows on Tuesday.

Asked if he will make good on recent claims, made in an interview with the New York Times ahead of the final Grand Slam of the year, that he intends to retire at the age of 27, Kyrgios replied "probs before that".

Pressed on whether or not the 21-year-old would change his stance if he became World No. 1 and was in peak form in six years' time, he wrote: "If I won the US open now u would never see me again."

It is perhaps unlikely the comment should be taken too seriously.  Kyrgios, no stranger to controversy on and off the court, offered several other sarcastic or dismissive responses to questions.

When it was suggested World No. 1 Andy Murray deliberately attempts to disrupt the Australian when receiving serve, Kyrgios replied "couldn't care less".

And when asked who inspired him the most at the recent Olympics, he said "kitty", a reference to Australia's prominent chef de mission Kitty Chiller.

The pair became embroiled in a row over the behaviour of Kyrgios, leading to his withdrawal from the Rio Games.
