Britain’s Johanna Konta saw off former world number one Caroline Wozniacki with a stunning display to reach the fourth round of the Australian Open.

Konta, seeded ninth, won nine games in a row on her way to beating the Danish 17th seed 6-3 6-1 in 75 minutes.

It was an eighth successive victory for the Briton, who won the title in Sydney in the build-up to Melbourne.

Konta, 25, will face Ekaterina Makarova next after the Russian upset sixth seed Dominika Cibulkova 6-2 6-7 (3-7) 6-3.

“We played in the fourth round here last year and I think it was 8-6 in the third, so I am expecting a battle,” Konta said.

“It will be tough, just like against anyone in any match, you don’t have any easy matches any more.”

Six-time champion Serena Williams – a potential quarter-final opponent for Konta – earlier beat fellow American Nicole Gibbs 6-1 6-3.

“I think if she keeps playing like this, then she has good chances against Serena,” Wozniacki said of Konta.

“Serena has won so many Grand Slams and she’s been in tough positions. But I think Johanna is playing on a very high level right now.”
