Andy Murray dismantled Nick Kyrgios on Centre Court to march on at Wimbledon this evening.
The British No 1 is the favourite for the SW19 title and with good reason based on this performance against the Australian bad boy.
It had been a tight match until the end of the first set when Kyrgios, as he so often does, began to lose his cool in south west London.
Kyrgios saved two set points but he then made an error at the net and handed the opener to the man from Dunblane.
It was the breaking point for Kyrgios, who is without a coach at present, and the Aussie showed his mental weakness under the glare of the spotlight.
He began to play erratically and surrendered the second set 6-1 as Murray took full control and began firing shots right across the court.
The third set continued in the same vein as Kyrgios made some more bizarre decisions and even refused to take his seat at the change of ends.
Lacking discipline, direction and drive, the tall Australian fell to pieces on the big stage and the Scot could not have wished for a simpler route into the quarter-finals.
Jo-Wilfried Tsonga awaits in the last eight.
Roger Federer, who is yet to drop a set in these Championships, is the only big gun left who will worry the Scot and even then the pair cannot meet until the finale.
He said: “I'm happy about my game that I've been able to rise now to the occasion and play a really good match against Johnson today.
"I think it was by far my best match. I'm confident also going to the Cilic match.”
Reigning women’s champion Serena Williams also made it safely through to the next stage today after defeating Svetlana Kuznetsova 7-5 6-0.
She said: “I felt like I was really dialed in, focused today, yesterday, and a little bit of the match before just towards the end.
"So, yeah, I'm just here to do the best I can.”
For Kyrgios, the inquest into his failure begins now and he might want to glance down to the tattoo on his forearm for a reality check. It simply reads: Time is running out.
