Looks like a young player with a very bright future.
Ivanovic's squeaky sneakers are gettin to the young Dane's serve.
I didn't know it if was just me but those sneakers are really loud on the television audio
I had the same observation of Wozniacki's groundstrokes as the thread starter, but having seen her play Morigami on the Tennis Channel last year I have noticed that she brought her ball toss WAY down on the serve. She used to have the highest ball toss I've ever seen.
