Although he ended up on the losing team, Nick Kyrgios was undoubtedly one of the stars of the inaugural Laver Cup at the weekend.
Kyrgios had the chance to force a deciding doubles tie with a match point in the final rubber against Roger Federer but, not for the first time, the Swiss used his experience to secure victory for Team Europe.
Having already picked up wins in both the singles and doubles earlier in the weekend, the young Australian can take a lot of pride from his performance and looked a completely different figure to the often disenchanted and unmotivated star on the ATP tour.
Being part of John McEnroe's Team World clearly brought the best out of Kyrgios and it meant so much to him he was even in tears after the defeat to Federer.
There will be plenty of fans now hoping it can represent a big turning point in Kyrgios' career. His talent has never been questioned but adding maturity and consistency to his game remains a problem.
If there is one thing we don't want him to change, though, it's his social media activity. No stranger to posting some controversial content on Facebook and Twitter, the 22-year-old likes to keep fairly busy online.
Well, he has been at it again.
After Sunday's emotional loss to Federer, one 'fan' called Clint Wilson commented on Kyrgios' post: "This Chump will never go close to beating Roger, Federer can actually Play Tennis.......and doesn't act like a hairdresser."
Kyrgios didn't take too kindly to that and shut him down instantly.
"Hi Clint - I've beaten Federer before. Thanks Clint. Bye Clint," he replied.
Game. Set. Match. Sorry Clint!
Of course, the first time Federer and Kyrgios faced off against each other in Madrid just over two years ago, the Australian recovered from losing the opening set to pull off a historic victory.
Despite Sunday's loss, their head-to-head record stands at 1-1 as the Laver Cup results do not officially count.
But that could all change if the success of the first edition of the tournament can be replicated in the future.
Kyrgios will certainly be hoping it does!
