MELBOURNE, Jan. 21 (Xinhua) -- Roger Federer and Serena Williams took routine wins to reach the quarterfinals of the Australian Open here on Monday.
An easy 6-4, 7-6(4), 6-2 win helped Swiss mogul Federer beat Canada's 13th seed Milos Raonic.
The 17-time Grand Slam champion gave up only five points on his first serve and hit 34 winners to reach his 35th straight Grand Slam last eight tie.
Federer wrapped up the first set when Raonic netted a volley, the second with a forehand down to the line to win the tiebreak 7-4.
Chasing his fifth title at the Melbourne Park, the Swiss will meet seventh-seeded Frenchman Jo-Wilfried Tsonga, a finalist here in 2008.
The 22-year-old Raonic, seeded 13th, missed another chance to be the first Canadian man into a Grand Slam quarterfinals in the Open Era.
Williams took only 57 minutes to beat Russia's No. 14 seed Maria Kirilenko 6-2, 6-0. It's the eight time for the 15-time Grand Slam champion to be in the last eight at Australian Open.
Williams twisted her ankle in her first round clash against Romania's Edina Gallovits-Hall, but still breezed through the first three rounds at Melbourne Park dropping just six games.
The victory was Williams' 40th from her past 41 matches will meet 19-year-old fellow American Sloane Stephens in Wednesday's quarterfinals.
Stephens qualified for her maiden Grand Slam quarterfinals with a 6-1, 3-6, 7-5 win over Serbian Bojana Jovanovski earlier Monday.
Another women's quarterfinals will be played between defending champion Victoria Azarenka and two-time Grand Slam winner Svetlana Kuznetsova.
Azarenka, the world No. 1, triumphed over unseeded Russian Elena Vesnina 6-1, 6-1.
Kuznetsova outlasted former world No.1 Danish Caroline Wozniacki 6-2, 2-6, 7-5. The unseeded Russian, the lowest ranked player left in the tournament, showed she was free of the leg injury that ruined her 2012 season.
In other men's fourth round matches, third-seeded Andy Murray qualified with a 6-3, 6-1, 6-3 win over Frenchman Gilles Simon and will play unseeded Frenchman Jeremy Chardy in the quarterfinals, who beat Italian Andreas Seppi with a 5-7, 6-3, 6-2, 6-2 win.
Seventh-seeded Jo-Wilfried Tsonga has joined fellow Frenchman Chardy after beating another Frenchman Richard Gasquet 6-4, 3-6, 6-3, 6-2.
