Radwanska marches into Aussie quarters
Agnieszka Radwanska has won her 13th consecutive match of the year, advancing to the Australian Open quarterfinals with a 6-2, 6-4 win over Ana Ivanovic.
The No. 4-ranked Radwanska, who won tournaments in Auckland and Sydney ahead of the Australian Open, will play 2011 French Open champion Li Na of China in the quarterfinals.
Li beat Julia Gorges of Germany 7-6 (6), 6-1 in an earlier match Sunday. Radwanska, who lost to Serena Williams in last year's Wimbledon final, advanced to the final eight in Australia for the third consecutive year.
Russian Maria Sharapova, earlier, skipped into the quarter-finals with yet another effortless victory.
The No.2 seed beat Belgian Kirsten Flipkens 6-1 6-0 in just 68 minutes.
Sharapova has now dropped just five games in her four matches at Melbourne Park.
''I'm certainly happy to be playing this well, but it only gets tougher from here,'' Sharapova said.
''I played a different type of opponent today than in my earlier rounds but I felt I adjusted really well.''
She now meets compatriot Ekaterina Makarova, who outlasted German star Angelique Kerber 7-5 6-4.
Last year 24-year-old Makarova knocked out Serena Williams in the same round - and now is looking forward to a possible match-up with second seed Maria Sharapova.
Kerber, the fifth seed, had won the past three meetings between the pair but struggled today and was intermittently treated for a back problem.
Makarova took 92 minutes to close out the match, running up three match points in the 10th game and sealing it with an ace at her first opportunity.
Sharapova, who has lost four games in three rounds, meets Belgian Kirsten Flipkens for a quarter-final place.
Makarova said she wanted to play the Russian because she had learnt a lot since her quarter-final appearance here last year.
"I really want to play Maria because I played against her a lot last year and I think it would be really interesting," Makarova said.
"I think I am more prepared this time.
"Last year I was surprised a little bit and had so many thoughts in my mind."
The Russian said she found it difficult to overcome Kerber with the German's speed and angled shots winning her so many points.
Makarova won the first two matches between the two but lost three times to Kerber in 2012.
