I think she's pretty much got this in the bag now.
She's improved her ranking from 34 at the end of 2010 to a guaranteed position in the Top 3 and is a safe bet for YE#2
She won her first GS at Wimbledon
She won four other titles, including Premier Mandatory Madrid
She's made it to the SF of YEC and looks pretty good for the finals
I really don't see who else is going to take it from her.
Li started on fire, but has done nothing since her FO win (except for bloody Maria!
Wozniacki was #1 for 51 weeks of the year, but has no slam finals, poor YEC performance and only real big title was IW, which is matched by Petra's Madrid
Serena and Kim had good results, but hardly played a full season between them!
Azarenka won Miami and could win YEC, but made no Slam finals
Sharapova... Lets not even try to pretend it could happen!
The only one who I think even stands half a chance is Stosur, and I can't see them giving it to her over Petra even if she wins YEC, because she did virtually nothing until her US Open win, crashed out early in the other three slams and has no other titles.
Anyone else think it's Petra's for sure now? Or do you think it'll go to someone else?
