MELBOURNE, Australia (AP) -- Two-time finalist Li Na has advanced to the Australian Open quarterfinals for the third time in four years with a 6-2, 6-0 win in just 59 minutes over Ekaterina Makarova on Sunday.

No. 4 Li, who broke No. 22-seeded Marakova's serve five times, lost to Victoria Azarenka in the 2013 final at Melbourne Park.

Li started this year by successfully defending her title at Shenzen and on Sunday improved her record at the Australian Open to 31 wins from 39 matches.

Li will play Flavia Pennettaon Tuesday. Pennettaon became the first woman through to the quarterfinals of the Australian Open with a 6-1, 4-6, 7-5 win over ninth-seeded Angelique Kerber of Germany on Sunday.

The 28th-seeded Pennetta, who turns 32 next month, has played some of the best tennis of her career since returning last year from a wrist injury that caused her ranking to drop as low as No. 166.

Pennetta reached her first Grand Slam semifinal at the U.S. Open last year and has followed that by reaching her first quarterfinal at Melbourne Park in 11 appearances.

Kerber was also bidding for her first quarterfinal at the Australian Open. She hasn't been past the fourth round of a Grand Slam since reaching the Wimbledon semifinals in 2012.

Eugenie Bouchard of Canada ended local hope Casey Dellacqua's Australian Open campaign with a 6-7 (5), 6-2, 6-0 win Sunday in the fourth round.

The 19-year-old Bouchard won 11 of the last 12 games to set up a quarterfinal against 2008 French Open champion Ana Ivanovic, who beat five-time champion and top-seeded Serena Williams in three sets earlier Sunday.

Bouchard, seeded 30th, is playing the Australian Open for the first time after making her inaugural appearances in majors last year, with the third round at Wimbledon her best previous result.
