Two-time runner-up Li Na took less an hour to beat Russia's 22nd-seeded 
Ekaterina Makarova 6-2, 6-0 and to reach the quarterfinals at the Australian 
Open here on Sunday.
The Chinese broke Makarova's serve five times to set up a quarterfinal clash 
with Italian veteran Flavia Pennetta. The No.23 seed beat Germany's ninth-seeded 
Angelique Kerber in three sets.
Li also improved her record against the 25-year-old Russian to 5-0. Their 
last meeting was at the 2013 US Open quarterfinals, in which Li won 6-4, 
6-7(5-7), 6-2.
Li, who lost to Victoria Azarenka in the 2013 final at Melbourne Park and to 
Kim Clijsters in 2011, reached the quarterfinal for the third time in four years 
and also improved her record at the Australian Open to 31 victories from 39 
matches.
