Just a bad match-up for Peer. She's better off grinding it out against the less mobile powerhitters. Leave it to Clijsters to kill the hype for any youngster. The only young player that can beat a good playing Kim is Sharapova.
I love how Kim at the top of her game can just effortlessly make some lower ranked players look like amateurs. And Peer was a pretty in-form player too. She truly is too talented to retire with only one slam.
