Wozniacki: "Nothing to prove" at Australian Open

Caroline Wozniacki says she will enter this year's Australian Open without anything to prove despite having risen to the No.1 ranking in women's tennis without winning a grand slam event.

Like Dinara Safina and Jelena Jankovic before her, Wozniacki has risen to the top without a victory in a major and has had to answer many questions about her legitimacy as a true No. 1.

Facing the media Saturday ahead of the Australian Open starting Monday, the Dane said "I've got great results, you don't become No. 1 by winning small tournaments ... I don't have to prove anything."
