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.
Jankovic at her dramatic best will lead, throw the lead away, spot you a massive lead in the third set, decide to come back with some blazing retrieving and backhands, almost comeback, and then hand you the win, possibly with back to back double faults or netted forehands. You have no agency in this match. You might start to wonder if you have free will. Perhaps solipsism is true after all - is it Jankovic's world and you're simply allowed to live exist in it? It's basically existential waterboarding.
