Australian Open 2012: Caroline Wozniacki beats Jelena Jankovic

Wozniacki survives second set scare to ease past Jankovic into last eight

World No 1 Caroline Wozniacki saw off a late fightback from Jelena Jankovic to ease into the quarter-finals of the Australian Open with a 6-0 7-5 victory.

The top-seeded Dane cruised early but was made to work hard to close out the match on a balmy evening at Rod Laver Arena.

Wozniacki, bidding for her maiden grand slam title, has not dropped a
set at Melbourne Park, but faces a far greater test against Kim
Clijsters in the quarter-finals.

'My confidence is high, my fitness is good, I feel like my play is improving,' Wozniacki said.

'I thought I played a great set and a half and then she started playing very well and got me back on my toes for a bit.

'I'm so happy to be through and even though I know some of the crowd wanted a long match, I hope you'll still support me.'

Up a set and coasting at 4-1 in the second, Wozniacki's victory charge was stalled when Jankovic broke back twice to level at 5-5.

But the world No 1 steadied by breaking the Serb again and sealed the match when Jankovic, who notched 50 unforced errors, sprayed a shot long.

The victory allowed Wozniacki to hold onto her top ranking for at least another few days. A number of contenders remain with a chance of swiping it should results go their way in the tournament.

Looking ahead to the last eight, Clijsters beat Wozniacki on both their previous meetings, the final of the 2009 U.S. Open and the final of the 2010 Tour Championships.
