Well... She is a great tennis player -without a doubt- is still very young and reached the final in RG and the semis in Wimbledon.. Then I saw her winning a US Open series tournament, I think that was LA, against Kuznetsova, and she bet Jankovic in quit impressive styl coming back from a 0-1 down in the sets...
But, besides all of this, I don't think she is going to be able to win the US Open, because to me she isn't consistent enogh in 1 match.. Sometimes she gets sooo many winners, but on other ocatios she just does to any unforced errore, and you can't do that if you want to win against masha, Henin or the Willimas sisters...!!
