Brilliant result. Hampton is a very talented player with a fantastic shotmaking ability, so to see her win against an overranked player like Hsieh is very satisfying. Besides I find her game rather unattractive.
Hampton's game has a kind of quiet potential about it. Some obvious flaws, but a compact looking game with flashy elements, especially her forehand which is capable of such beautiful ball-striking. This kind of surface will probably prove ideal for her too.
Hsieh is a fraud with that kind of ranking, so these kind of results are always much needed.
Wozniacki has magnificent shotmaking if you ask me, but it's not the power kind of one. She has to rely on all court tactics to make effective her sweet topspin mix, while still able to hit pretty decent winners when she feels them, especially with the backhand. Despite not making many winners, she's still an agressive baseliner, and she doesn't only win matches by waiting the opponent's mistake, though she can do that at times also.
