Career Singles Titles: 16

Sealed her place at the top of the women's game earlier this this month when she became the first Belgian to be ranked number one in the sport.
But still without a grand slam title under her belt, Clijsters needs to achieve her breakthrough quickly at one of the four major tournaments to get the critics off her back.
Brimming with confidence after claiming her sixth title of the year in Los Angeles, the gutsy baseliner will be ready to do damage with her thundering groundstrokes and penetrating serves.
