Who can stop Serena Williams in Australia?

Serena Williams is not the No. 1-ranked player in the world, but that doesn’t mean she’s not the No. 1 player in the world. Just ask anyone.

Victoria Azarenka, No. 1 by virtue of points, is the defending Austalian Open champ. Maria Sharapova has a championship pedigree and won a Slam last year. Can they dethrone Serena? What about Agnieszka Radwanska, who made huge strides last year? Petra Kvitova has the tools, but does she have the mental stamina to last for two weeks?

There are a lot of questions, for sure, but dissecting the state of women’s tennis begins and ends with Serena Williams.
