(14) Maria Sharapova
- DOB: 19/04/1987
- Nationality: RUS
- Became Pro: 2001
- Height: 1.88
It was assumed that the Grand Slam titles would continue to come when Sharapova beat Ana Ivanovic in the Australian Open final three years ago, but her career has been derailed since then.
The victory was followed later that year by a shoulder injury that would sideline her for several months and from which her ranking has never recovered.
Since then the 23-year-old has struggled at the Grand Slams, with a run to the quarter-finals of the 2009 French Open the best she has managed since the lay-off.
And when she returned to Melbourne last year for the first time since her win, she was dumped out in the first round by fellow Russian Maria Kirilenko.
Apart from that blip, however, she has a fine record at the Australian Open, reaching a final and two semi-finals as well as taking the title, and not many - if any - can live with her power game if she finally manages to regain top form.
