The Russian demolished Flipkens 6-1, 6-0 and has now dropped just five games in her first four matches in Melbourne.

"I was making a few more mistakes than I would have liked in the beginning," Sharapova said on the tournament website.

"After I held at 2-1, I really started making her play a little bit more. Started really getting under the ball and being aggressive and just had a little bit more energy which really helped me and I carried that throughout the match."

Sharapova`s quarterfinal opponent is fellow Russian Ekaterina Makarova in a rematch from the same stage of last year`s tournament.

Sharapova won that encounter 6-2, 6-3 and has never lost to the 19th seed in four meetings to date, but said she refused to look beyond her next match.

"It`s not about waiting to see where you are in the semis or finals. It`s about who`s ahead of you and my next match is against Makarova. I have to do the right things to beat her," she said.

Makarova upset a higher-seeded player for the second round in a row Sunday, beating fifth-seeded German Angelique Kerber 7-5, 6-4 in an aggressive performance in which she hit 32 winners.

Makarova said she was keen for revenge over Sharapova.

"We played a lot of times, and I never beat her. So I`m really interested to play against her. She`s in good form now, in good shape," she said.

Another player to reach the quarterfinals was China`s sixth seed Li Na, who disposed of eighth-seeded German Julia Goerges 7-6(6), 6-1.

The key to Li`s victory was Goerges missing a set point in the first set, the Chinese player said.

"I was laughing a little bit. I was happy I`m still on the first set, you know. After the first set, I think she had a breakdown a little bit in the mind," Li said.

Li goes on to play either fourth seed Agnieszka Radwanska of Poland or Serbian 13th seed Ana Ivanovic.
