Roger Federer reached his 57th grand slam quarter-final with a 4-6 6-1 6-2 6-2 victory over Marton Fucsovics.
The Swiss maestro overcame tough conditions and a rusty opening set to reach the Australian Open last eight with a four set victory.
It now means Federer will play his 15th Australian Open quarter-final and his 57th grand slam last eight when he plays world number 100 Tennys Sandgren on Tuesday.
After an epic match with John Millman a couple of days ago, Federer was hoping that victory would give him confidence against an in-form Marton Fucsovics.
There were some confident moments to start the match as Federer struck the ball cleanly off both wings as he looked for a fast start.
But Fucsovics was also hitting the ball well, creating wide angles to make life difficult for the 20-time grand slam champion.
Eventually it was the Swiss maestro who would blink first as a poor game full of unforced errors and poor decision-making handed the early break to the Hungarian.
Fucsovics kept his cool and continued to play with bold as well as brave tennis to hold his nerve and seal the opening set in 37 minutes.
However the first set was the only set where Fucsovics played anywhere near his best tennis as Federer stepped up a gear for the rest of the match.
Using good variety, Federer settled into a rythym as the winners flowed from his racket as the Hungarian started to fade especially on serve.
Two breaks of serve was needed in the second set as he blasted his way to the second set, 6-1.
Another masterclass was handed out in the third set although not without struggled as Fucsovics capitalised on Federer inconsistency to break late in the set.
Although by that point Fucsovics was two breaks down when he broke and Federer broke him back anyway as he shortened the points up at the net as the 3rd seed took a two sets to one lead.
In a match lacking in quality, it was Federer who proved to be the more ruthless and clinical player as he took advantage of a lethargic Fucsovics.
Another two breaks of serve sealed a spot in the quarter-finals of the Australian Open for a 15th time in his career. Next up will be world number 100 Tennys Sandgren on Tuesday.
After the match, Federer admitted the conditions were tough to play in, “Was a tough start,” Federer said in his post-match interview.
“I thought that Marton played clean. It was the rest of the Millman match, he gave me a beatdown from the baseline, so maybe took my confidence away a little bit, and it just took some time.
It’s really slow in the night time especially when it’s cool like this. I had to figure it out, finally found a way at the start of the second set and from there, things got a little bit easier.”
