I think she'll win it at one point in her career. But I would bet that she'd get the AO title first before she gets this. I think she did handle the pressure better than she did before. This of course is considering that the pressure she had was more than that of last year. More people expected her to win this year's RG.
The last time she had an amazing run at the clay courts before RG, she lost in the 1st round. Although she just equaled her best performance, I think it is more of a step forward.
She really needs to be more aggressive. She is just so defensive in this tournament. She needs to attack and step it up. And usually this is hampered by the pressure and expectations laid on her. I would expect her to win this when no one would really expect her to win it. She's one of the best claycourt players out there, so her chances on clay are quite good.
