American tennis great Jim Courier believes Nick Kyrgios has reached a turning point in his career and the young Australian's on-court stability this summer shows his best tennis is still to come.
The former world No. 1 and two-time Australian Open champion heaped praise on the 22-year-old for his ability to change his behaviour.
Courier, who is commentating for Channel Seven throughout the tournament, also says the Australian public can afford to be more patient with Kyrgios, given how long he has left in his career.
"I think this whole Aussie summer feels like it's been a pivot point for him, it seems like from my very outside position that he's in a really nice place in his life," Courier told Fairfax Media.
"He's got stability off the court and that's maybe helping him being mentally stable on the court and he's handling adversity in a better way ??? and that is maturity.
"Players are playing much longer careers these days, well into their 30s, so he's very much in the beginning phase, the beginning third of his career.
"It is important sometimes to take a 10,000 foot view, for everyone to take a step back and say; look, this guy is learning a lot, he's under the microscope, he's made mistakes and he'll make more but hopefully he will learn from them."
Kyrgios will feature in most of the most-awaited matches of his career when he confronts French veteran Jo-Wilfried Tsonga, one of his childhood heroes, before a packed Rod Laver Arena crowd on Friday night and a large TV audience.
The two-time grand slam quarter-finalist showed maturity and resilience in his victory over Serbian Victor Troicki on Wednesday night, overcoming several distractions to post a straight sets win at Hisense Arena.
He had to deal with a disruptive fan who was ejected by security, a helicopter that lingered above the court for much of the second set and a faulty PA system that was sending the crowd into hysterics.
"I think last year, the year before, I probably would have been still out on the court right now, could be losing that match," Kyrgios said after the match.
Late last year, Kyrgios spoke about a vision he had for his own charity. A facility for disadvantaged children to - in his own words - "hang out, be safe and feel like they were part of a family".
Kyrgios referred to it as "finding a purpose".
"For the first time, I feel like there is a reason for me to be doing what I'm doing. Tennis is a great life - we're well paid and the perks are pretty good - but it can feel empty if you're just doing it for the money," he wrote in Players Voice.
Courier believes that Kyrgios has found a way to put all his energy into focusing on the match.
"It seems like right now he is on the court managing his stress levels better," Courier said.
"I think he'll handle the stress pretty well because it's a match that if he loses it, it's not that big of a defeat, he can see this as a successful Aussie campaign."
In a tough third-round clash between the 15th and 17th seeds, Kyrgios comes up against a fellow showman and a childhood hero in Tsonga.
A decade ago, when Tsonga made the final in 2008, a 12-year-old Kyrgios went to every one of the Frenchman's practice sessions, taking a new ball every day to be signed.
Ten years on at the same venue, the Australian will be looking to eliminate one of his idols in his quest for glory at his home grand slam.
Courier, who won the Australian Open back to back in 1992-93, also believes it's important to remember that Kyrgios has time on his side.
"It's looking good for Nick, I'm bullish," he said.
"Baby steps are important, just take steps forward. You get knocked down, you get back up and you figure it out.
"Every young athlete makes mistakes, how you learn from them and go forward and try to get the most out of what you have, those are the challenges every athletes faces.
"Nick is not exempt from that, he just is under a much more refined microscope than most."
