That looked so completely staged. The replay didn't look like she went down on her leg and the way she screamed looked like something out of a play. And considering how dramatic Pierce is, I wouldn't put it past her.
In fact, I tried a stunt like this last year in jr. year tennis when I didn't feel like playing. And I fell just like that and screamed just like that and got to skip my match.
Maybe I'm being heartless but I think Pierce is faking.
