I find Petrova is a very talented player. She is very powerful, has a very big serve, big weapons off both forehand and backhand, is a pretty good athlete. She has won Premier titles and has beaten everyone in the game multiple times I believe- Serena, Venus, Henin, Clijsters, Sharapova. Why hasnt she won a big title? She seems to be in that role of dangerous floater but not even real contender.
