She has been on a horrible slump since Wimbledon. She can't seem to win anymore. So far this year two straight first round losses in straight sets, yesterday to Mara Santangelo 61 61. Last year she beat Jankovic in the AO warmups. Now she is a total non factor losing badly to fair / mediocre players. She is just 19 or 20. Just a few years ago she won three straight WTA tournaments at 16 or 15. She should be blossoming now into a WTA force but she seems to be regressing. This would be a sad story if she were to burn out and fade away before the age of 22. Does anyone know? is she playing with injury? What has gone wrong with her game?
