On the topspin serve explanation, I don't get the part about brushing "up and over" the ball from 6 to 12.
Specifically, the "over" part confuses me: When the ball is thrown above your head, you're naturally going to strike "up" at 6 o'clock (the ball only stays on your racket for a fraction of a second - so how do we get it to 12?) - I'm basically brushing from 6 to the middle of the clock, because I don't know how get as much tennis ball surface on the racket strings.
Does the "over" mean supinating your wrist or forearm a little to get the racket to curve upward to 12? - or what am I missing here?
