Toronto's Sharon Fichman reaches doubles quarter-finals
Rafa Nadal eased past Italian 16th seed Fabio Fognini 6-3 6-4 6-2 to reach his 13th Australian Open quarter-final on Monday.
The Spanish second seed, who is chasing a record 21st Grand Slam title, held steady against the fierce hitting of Fognini and counter-punched brilliantly.
He set up a quarter-final meeting with Greek fifth seed Stefanos Tsitsipas, who advanced to the last eight after ninth seed Matteo Berrettini withdrew due to an abdominal strain.
Daniil Medvedev brushed aside Mackenzie McDonald 6-4 6-2 6-3 to extend his winning streak to 18 matches and set up an all-Russian quarter-final with Andrey Rublev, who was gifted a place in the last eight after Norway's Casper Ruud retired injured.
Medvedev and Rublev join Russian qualifier Aslan Karatsev in the quarter-finals, making it the first time in the Open era that three Russian men have reached the quarter-finals in the same Grand Slam.

Top-ranked Ash Barty sealed a dominant 6-3 6-4 victory over American Shelby Rogers to reach at least the quarter-finals for the third year in a row.

Fichman and Olmos lost both opening games of the two sets played, but didn't trail at any other point in the match. They needed 45 minutes to win the first set, and only 32 minutes more to win the second set.
