Nick Kyrgios has again hinted at an early retirement from tennis, saying this year’s Laver Cup is likely his last and revealing that his season was over.

The 26-year-old Australian fell to a 6-3 6-4 defeat to world No. 3 Stefanos Tsitsipas in Boston on Saturday, before falling in doubles to Tsitsipas and Andriy Rublev while partnering American John Isner 7-6 (10-8) 6-3 10-4.

Kyrgios showed plenty of honesty after the clash with the Greek star, opening up on his plans for the season and beyond.

“This is my probably my last Laver Cup,” Kyrgios said.

“I don’t know how much longer I will be in tennis.

“This is my last event of the year. I will get my body right ahead of the Aus Open.

“My mum is not doing too well with her health. I’d like to go back and see her.”

At 26, Kyrgios could comfortably compete on the world stage for the best part of a decade – or even more, as veterans like Roger Federer, Rafael Nadal, Stan Wawrinka, and his doubles partner Isner proved. All are 35 or older. But Kyrgios has repeatedly stated his desire to retire by 30, something he again reiterated today.

“As long as I’m on the court, I will try and give my best,” he said.

“But I’m not going to lie and say that I’m going to plan to play four or five more years on tour.”

Kyrgios has lost his previous four tour-level singles matches – a streak that extended to five with the demonstration Laver Cup event included.

After reaching the third round at the Australian Open and Wimbledon this year, the former world number 13 is on the brink of dropping out of the world’s top 100.

His current rank of 95th is his lowest since June 2014, when the then-19 year old tyro – ranked 144th in the world – surged to the quarterfinals on his debut at Wimbledon. That magical run included one of the finest wins of his career – beating world number one Rafael Nadal in the fourth round – and had the tennis world believing the Australian would become an eventual grand slam winner.

That dream is still alive. For now at least.
