Nick Kyrgios, who will play the Davis Cup quarterfinal for the Aussies in Brisbane, Australia starting on Friday, says that he is playing substantially better because he is competing better.

In Miami, the 21-year-old Kyrgios reached the semifinal, barely losing to Roger Federer, 7-6 (9), 6-7 (9), 7-6 (5). It was his third semifinal in four events.

Kyrgios said that, finally, he is maturing.

“I think my level's always been there, but where I'm at mentally, at the moment, I'm just competing for every point and playing hard, and I haven't really had that mindset before,” Kyrgios told *The* *Sydney Morning Herald*. “I'm probably in the best place I've ever been in.”

He is again leading the Davis Cup team this week, having said that playing the first round of the team competition helped him turn around his season.

Now, he wants to help his Australian countryman.

“Being with these guys again, they only lift me up,” Kyrgios said, “and hopefully we can come together as a team like we always do and get the result we want this weekend. It's just having their support every day, a couple messages waking up to or if I’m struggling. I know that the results I have in these tournaments can really help those guys in their tournaments.

"But also coming back to set a good example, everyone can see that I'm playing well, and it lifts them up and helps them play well.”

The Australians are playing the United States, and No. 16-ranked Kyrgios will likely face world No. 15 Jack Sock on Sunday.

At this point, Sock is scheduled to play twice in singles, and is also the top doubles player. But the team has three other men who could play singles or doubles if required— No. 23 John Isner, No. 25 Sam Querrey and No. 29 Steve Johnson. Querrey and Johnson have played doubles together before.

On the Aussie side, Bernard Tomic was not picked. No. 79 Jordan Thompson is scheduled to play  the second singles, and Sam Groth and John Peers will likely play the doubles.
