MELBOURNE: World number two Rafael Nadal on Monday entered the Australian Open quarter-finals for the 13th time after getting past Fabio Fognini in their fourth round contest.
Nadal, the 2009 champion, registered a 6-3, 6-4, 6-2 win over the Italian No. 16 seed in two hours and 16 minutes at the Rod Laver Arena.
"When you go on court against Fabio, you worry, " said Nadal after the match as per the ATP Tour website.
"There can always be problems. I was just lucky that when he broke me (in the second set) I responded immediately and held the score. Today was very humid and quicker during the day, which I like, but I have to adapt to every condition, " he added.
The 34-year-old is looking to become the first man in the Open Era to clinch each of the four major championships on two or more occasions.
He will next face fifth-seeded Greek Stefanos Tsitsipas, who received a walkover after No. 9 seed Matteo Berrettini of Italy withdrew due to an abdominal strain.
Earlier in the day, fourth seed Daniil Medvedev also booked his place in the quarter-finals after a commanding straight-sets win over Mackenzie McDonald.
Medvedev beat the 25-year-old American 6-4, 6-2, 6-3 in his fourth-round match that lasted an hour and 29 minutes at the Margaret Court Arena. He will face Andrey Rublev in what can be a blockbuster quarter-final clash on Wednesday.
