Makarova dumos out Kerber

Ekaterina Makarova made it through to the quarter-finals of the Australian Open with an impressive defeat of fifth seed Angelique Kerber.

Makarova's best run at a grand slam came here in Melbourne 12 months ago when she reached the last eight with a stunning upset of Serena Williams.

And she matched that achievement by playing the role of giantkiller once again on Rod Laver Arena, knocking out the German 7-5 6-4.

"It's an unbelievable feeling, I really like playing here," the Russian said.

"I lost three times to Angelique last year, she is so good so I am very happy."

Makarova went out to Maria Sharapova last year and the pair will clash again should the second seed beat Kirsten Flipkens later today.

"I hope I play Maria," said Makarova. "Last year I was surprised to reach that stage and I had so many thoughts in my mind. This year I will be ready to play a good game."

Makarova was the more positive player throughout and held herself together after squandering a 5-2 first-set lead.

She broke for 6-5 and then served it out to edge ahead.

Kerber's chances of finding a route back into the contest were hampered by a back injury and a solitary break in the ninth game proved decisive.
