The Australian Open 2012 is the first Grand Slam of the year and it is going to be amazingly exciting. Six players on the womens side have the ability to finish the tournament with the World Number 1 ranking.
Victoria Azarenka, Maria Sharapova, Sam Stosur and Agnieszka Radwanska could also take the top ranking, but the No. 2-ranked Kvitova is the favorite.
Caroline Wozniacki currently holds the top spot, but with her poor run in Grand Slams I doubt highly that she will be number 1 when the tournament ends.
