Indeed, Sorana is a hottie--and will be more so after a little training. (The trouble with her feet may well go away if she drops as little as five to ten pounds.)
I wanna say that the foot trouble wasn't all she had to contend with yesterday. The match with Radwanska was on a playing field far from level! She had good reason for her outbursts. A number of line calls were seriously suspicious and even the Yank commentators were moved on one point to question the chair's behavior. Frankly, I felt some of his decisions were to offset Radwanska's incompetence--particularly in the first & part of the second sets.
This has to be regarded in the context of the coverage. The "world feed" (same thing Eurosport is showing) was so blatantly tilted to put Radwanska in your face that is was not amusing. It was very clear who the broadcasters favored.
After Sorana won anyway, ESPN2 replayed the match after Maria's last night. Guess what? The tape had been noticeably retooled to create the illusion of fair & balanced coverage! See, these sh!ts know exactly what they're doing.
So, Cirstea had an uphill fight in many ways. At this point, (with movement issues due to foot pain) I think she could only take Stosur if Sam nods off but we know that can happen. 
Whatever way things go tonight, however, Cirstea has already accomplished a lot here.
