Roger Federer maintained his record of not having dropped a set at the Australian Open with a straightforward victory over Marton Fucsovics to reach the quarter-finals.
The 25-year-old Hungarian was a surprise face in the fourth round and acquitted himself well on Rod Laver Arena but ultimately proved no match for the defending champion, who won 6-4 7-6 (7/3) 6-2.
The victory sends Federer through to the last eight in Melbourne for the 14th time and 52nd overall in grand slams, where he is likely to be more severely tested by Tomas Berdych.
This was a first meeting for the pair, although Federer played Fucsovics' coach Attila Savolt in the second round in Melbourne 16 years ago.
Federer was also playing during the day for the first time all tournament after three matches at night but had no problem making the adjustment and is the oldest man to reach the quarter-finals here since Ken Rosewall in December 1977.
The 36-year-old said: "I thought he played very well. Fast conditions, you have to have quick ideas and execute well and I think he did that very well. I had a hard time breaking through until two sets to love and a break. Credit to him for playing a great tournament, that's what I told him at the net."
Berdych has been flying under the radar this fortnight but, after beating Juan Martin del Potro in straight sets, he followed up with an impressive 6-1 6-4 6-4 victory over Fabio Fognini.
