My sentimental favorite for this year's French Open is Ana Ivanovic, who now has a new coach and really played well during this clay court season. She also gets a good draw! I'm even predicting that she could reach the semifinals on her side of the draw.
Anyhow, Sam Stosur and Ana Ivanovic should be the semifinalists in the upper part of the draw, while Li Na and Serena Williams, on the lower part. As for the finals, I'm thinking Sam Stosur vs. Serena Williams - and I think Sam Stosur SHOULD finally win it this time!! She has defeated Serena on the Grand Slam stage, that's how she won her US Open title - and looking at the way she played during the clay court season, she's as tough as nails nowadays, so even with Serena across her, I don't think it'll faze her.
