However Serena has had quite a few injuries this year and they seem to be occurring around the grandslams.
I would say that barring injury then I cannot see her losing in this tournament. I also think that Maria has a great chance of winning this tournament her confidence would be high after winning the French Open.
Looking at the draw I would not be surprised if Venus Williams was able to string some results together and win this title.
Li Na is someone else I can imagine winning she has a good draw and will be difficult to beat.
I am hoping that Britain's Heather Watson will follow up on her Eastbourne success and at least make it to the third round and this could see her getting back into top fifty.
In the men's draw my personal favourite to win would be Rafael Nadal. However he faces a stiff challenge from players like Novak Djokovic, Roger Federer or last year winner Andy Murray.
The dark horse in the men's draw would be Stanislas Wawrinka he is the current Australian Men's champion and he has got a strong grass court game and will be tough beat.
