Australian Open: Wozniacki beats error-strewn Jankovic

Women's top seed Caroline Wozniacki saw off the challenge of former world number one Jelena Jankovic on Sunday to reach the quarter-finals of the Australian Open.

The Dane raced away with the first set and edged the second to win 6-0, 7-5, with the Serbian 13th seed making a huge 50 unforced errors in a match lasting 1hr 43min.

Wozniacki looked like running away with the contest when leading 4-1 in the second set, but Jankovic staged a late comeback before the Dane sealed the win on her second match point.

"My confidence is high, my fitness is good, I feel like my play is improving so I'm very positive," said Wozniacki. "I thought I played a great set and a half today but then she started to play well."
