Australian Open 2012 live stream

For many tennis pundits, the big void next to world No.1 Caroline Wozniacki's name is the lack of a Grand Slam title.

Nevermind the fact she's still only 21, the expectation seems to be that she 'should' have a major title as a world No.1.

While the upbeat Dane tends to avoid going into depth when answering questions on that subject at press conferences, she must have that goal clearly in mind for this year, and here at Melbourne Park in 2012 she's proving that she is a huge contender..

On Sunday night she found her way past a former world No.1, Jelena Jankovic, 6-0, 7-5 in just over ninety minutes at Rod Laver Arena, in what was supposed to be her toughest test yet at this year' tournament.

Granted, the 13th-seeded Serbian played a shocker - she somehow managed 50 unforced errors and seven double faults in the two set match. However, that can't take away from Wozniacki, who was consistent, smart, and held tough even when Jankovic finally applied some pressure late in the second set.

After racing to the first set 6-0 in just over half and hour, the Dane was on course for an early finish until mid-way through the second when Jankovic found some rhythm, hitting the lion's share of her 26 winners in that period.

Wozniacki conceded two breaks in the second set, but each time she rebounded, showing great composure and persistance.

A huge fist-pump followed when Wozniacki finally served out the match.

While there are a number of other top contenders still in the draw, including the in form Victoria Azarenka, and the five-time champion Serena Williams, Wozniacki is showing a steely determination in this year's tournament that could just take her a long way.

That determination will be put to the test on Tuesday, when, ankle fitness permitting, she'll face last year's champion Kim Clijsters for a place in the semi-finals.

More to come ...
