Day three from the Australian Open at Melbourne Park
Seriously though, as Russell said, wasn't it wonderful to see a dramatic match like that enjoyed by a captivated and clamourous crowd?
Amazing. And a reminder that sport can help us all forget our worries for a few hours.
Thanks Nick Kyrgios! Thanks Ugo Humbert! Until next time...

We have been thrilled by sport and had a crazy audience to enjoy it with us - we've all been missing that for so long. They put a smile on everyone's faces today.
Kyrgios 5-7 6-4 3-6 7-6 (7-2) 6-4 Humbert
How on Earth did Nick Kyrgios pull through that one? He faced two match points in the fourth set ICYMI.
"I just remember down that end when I was a couple of match points down and somehow got out of it," he says.
"It was a strange match, there were some dark thoughts inside my head. It seems to be my career, I live to fight another day and hopefully I can continue to play tennis like that in front of you guys."
On his next opponent: "Dominic (Thiem) is a heck of a player, I played him one time five or six years ago but I am thinking about the doubles tomorrow."

More from Kyrgios on the man he beat, French 29th seed Ugo Humbert: "He is a heck of a player. He played amazing tennis... I felt like the one thing I had on him is experience so I drew on that experience, playing in front of you guys, I tried to get my head down and make him play."

Here are the thoughts of Nick Kyrgios...
"You guys were awesome again, honestly if you were in my head I was just thinking about all the **** I was going to cop if I lost that match.
"I don't know how I did that, it's one of the craziest matches I have ever played."
Kyrgios 5-7 6-4 3-6 7-6 (7-2) 6-4 Humbert
Kyrgios was stalled by the jeers for Thiem, but not by a marriage proposal which could be loudly heard on the microphone.
Is NK marriage material?! Not sure.

Nick Kyrgios just loves "crazy" matches on this court.
Just 12 months ago he had a similarly dramatic match against Karen Khachanov, only then it was him who missed match points before recovering.
Not sure his third-round match against Dominic Thiem - whose name is greeted by a few jeers from the Aussies - will be on the Melbourne Park third showcourt though...

With the John Cain Arena crowd still going mad, Nick Kyrgios heads to the middle of the court for a chat with Jim Courier.
Kyrgios says it was one of the craziest matches of his career and reckons he was thinking about all the, erm, 'stick' he would receive if he lost that match.
More quotes from the main man shortly...

Ugo Humbert will feel absolutely gutted but he gave his very best. I also feel emotional for Nick Kyrgios because these are the moments you play for.
Kyrgios 5-7 6-4 3-6 7-6 (7-2) 6-4 Humbert
Shaking his head in his chair, Kyrgios can't quite believe it.
Neither can Humbert, whose eyes are on stalks as he wanders off shellshocked.

Nick Kyrgios looks very weary now as he slumps in his chair, we'll find out on Friday how much he has got in his tank. Kyrgios played brilliantly from the end of the fourth set on. I think he's feeling pretty emotional.
Kyrgios 5-7 6-4 3-6 7-6 (7-2) 6-4 Humbert
No wonder Nick Kyrgios drops to the floor. What an effort from the unseeded Aussie.
Sensational effort, sensational drama, sensational atmosphere. Ohhhh, how we have missed this.
Kyrgios 5-7 6-4 3-6 7-6 (7-2) 6-4 Humbert
He only needs one! Incredible.
Nick Kyrgios bounces down a testing serve and Humbert can only scoop long - he is through to the Australian Open third round!!
Two match points saved, five sets battled, but he's through.

Here we go again. Two match points for NK. This time on his racquet...
*Kyrgios 5-7 6-4 3-6 7-6 (7-2) 5-4 Humbert
Not only are they on their feet, the Aussie crowd are stretching a vocal cord with the noise which they are creating.
It's like a boxer returning to the ring for the final round...
Anne Keothavong
Former British number one on Tennis Breakfast
It really has been an inspired performance from Nick Kyrgios and the crowd have played their part to help him in this battle - I'm sure they'll be on their feet.
*Kyrgios 5-7 6-4 3-6 7-6 (7-2) 5-4 Humbert
I tell you what... that is gutsy. Humbert could have crumbled but somehow reset mentally and dug himself out of a hole there.
The Frenchman fights off the match points before clinching the hold with an ace.
Over to you Nick...
Kyrgios 5-7 6-4 3-6 7-6 (7-2) 5-3 Humbert*
Oh no!! Back-to-back double faults see Kyrgios have a match point...
Kyrgios 5-7 6-4 3-6 7-6 (7-2) 5-3 Humbert*
Over to Monsieur Humbert. Imagine the thoughts which are befuddling his mind right now...
The French 29th seed serves to stay in the match and in the Australian Open...
