Wang Chen, formerly of China, now residing in the US, ranked #31 in the world. This is a shot of her match against Viktoria Pavlovich of Belarus.
Here you can see the effort Wang exerts to lift Pavlovich's underspin chop. Wang Chen lost this match, but got some measure of
revenge in the doubles finals, where she and Liu Jia met and defeated Viktoria and her partner in 5 games.
