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 the Flavia Pennetta in the quarterfinals on Tuesday. Pennetta earlier beat No. 9 Angelique Kerber.
