Hesse grew up on clay, playing at an all clay court club.
But certainly likes to think of herself as a hard court player (all pace and power, not too much of this nasty, sweaty running-around stuff).
However, I sometimes think she actually plays better on clay - doesn't spray the ball around quite so much, not going for winners off every ball, and has slightly more time on the ball to get positioned a bit better.
It's a lot to do with 'between the ears' stuff for Amandine . . .
