Vaidisova beat Myskina, Jankovic, Dechy, Golovin and Petrova last year. Those are the 5 I quickly picked out from her results last year. I personally like Golovin, Vaidisova and Ivanovic. Golovin the best and the other two not far behind and wish them all the best of luck this year and hope they continue moving up the rankings.
Here are some of Ivanovic's results: She lost 6-2, 7-5 in Australia to Mauresmo. She beat Petrova, Vaidisova, Kuznetsova, Dechy, Mauresmo, Jankovic, Golovin(2).
