She'll always be in danger of looking powerless against big hitting players who play with confidence like Goerges or Petkovic if they hit some really good form, and that's almost bound to happen in the later stages I guess.
Problem with Woz is that, though she's consistently good, or very good, she is rarely great/awesome/godlike (it does happen sometimes
), and anything but great isn't good enough when you face a player that can hit with power off both sides and doesn't make a lot of ue's.
To her credit she does seem to cope much better with variety, players like Schiavone and MJMS that used to give her a lot of headaches look pretty much powerless against her now as she improved on her all court skills.
But she has to develop a game for the big hitters if she wants to win a few slams.
With all that said I think she's got a very good chance this year. Yes, there are girls who can hurt her but a lot of things have to add up for Azarenka, Stosur, Zvonareva, Petkovic, Wickmayer etc.. for them to be a real threat,..Wozniacki will do well, will it be enough I don't know but given the competition right now it just might.
