Lleyton Hewitt says his Davis Cup team helped speak Nick Kyrgios’ hot streak, which has seen the world No.16 book a Miami Open semi-final clash with Roger Federer.

Kyrgios will be a late arrival for Australia’s Davis Cup quarter-final against the United States in Brisbane starting on Friday thanks to his impressive Miami form.

But Australian captain Hewitt – already in Brisbane with the team – had no issues with the tight schedule, saying he knows how much Davis Cup tennis means to a revitalised Kyrgios.

Hewitt said Kyrgios revelled in the team environment of February’s first-round win over Czech Republic at Kooyong: “I think the Davis Cup at Kooyong really helped kick start his year again,” Hewitt said. “He was obviously disappointed with how he lost at the Australian Open.

“He came to the tie and had all the support of the boys and he got the job done. I think it gave him a lot of confidence and belief and since then he has hardly put a foot wrong.”

Hewitt has been impressed with Kyrgios’ commitment to playing for his country.

“He’s made it one of his big goals and that is really pleasing to see,” Hewitt said. “That is what I wanted to install into these young blokes, what it means to wear the green and gold and play for your country.

“And Nick loves that aspect of teammates who have his back.”

Hewitt does not believe that Kyrgios’ late arrival into Brisbane will be a problem when taking on the Americans.

“If he is serving well on the practice court then the rest comes together quite nicely,” he said. “And I know that he can’t wait to come here and join up with the boys again.”
