I'd say Zheng has a fairly reasonable draw - though the Czech's are good players, I don't think any of them are far above Zheng's league that she wouldn't have a chance to win if she plays well.
Unfortunate for Na, I'll be a bit surprised if she's able to put up a whole lot of resistance against Lindsay but hopefully her match with Sharapova will at least give her some experience so that she won't seem as nervous as she did playing Masha.
"Religion has actually convinced people that there is an invisible man living in the sky who watches everything you do, every minute of every day. And the invisible man has a special list of ten things he does not want you to do. Any if you do any of these ten things, he has a special place, full of fire and smoke and burning and torture and anguish, where he will send you to live and suffer and burn and choke and scream and cry forever and ever 'til the end of time!
But he loves you."
