Second seed Caroline Wozniacki into Australian Open last 16

World number two Caroline Wozniacki kept her bid for a first Grand Slam title on course as she stormed into the last 16 of the Australian Open on Friday.

The second seed only scraped through to the third round by the skin of her teeth, saving two match points at 5-1 down in the third set against 119th ranked Jana Fett.

But on Friday she gave her most assured performance of the tournament so far, cruising past Kiki Bertens of the Netherlands 6-4, 6-3 in an hour and 26 minutes.

She next faces 19th seed Magdalena Rybarikova of Slovakia for a place in the quarter-finals.
