Former champion Rafael Nadal and fourth seed Daniil Medvedev both cruised into the Australian Open quarter-finals.
Nadal, the 2009 winner and number two seed, gained a routine win over Italy’s 16th seed Fabio Fognini at Melbourne Park.
Nadal will face Stefanos Tsitsipas in the last eight on Wednesday.
The Greek fifth seed was handed a walkover win in round four after Matteo Berrettini of Italy had to withdraw because of an abdominal injury.
Nadal’s victory means he has reached a Grand Slam quarter-final for the 43rd time, going on to win 20 titles, although his only success in Melbourne was 12 years ago over Roger Federer.
