In this clip we're going to talk to you about the American twist serve. You might have heard, Sampras has used this quite a bit, Andre Agassi uses quite a bit, lots of players actually on tour, but they're using a specific serve, certain locations. And this is the American twist, a lot more advanced, this is pretty tough, but the idea is you're getting the combination between slice and top spin. The top spin is going from six to twelve. Going straight up. In your slice, you're going to get hit in that three o'clock, that right side position right there. So now you're going to try hit in between, maybe two o'clock, maybe one o'clock right there. Trying to go up at an angle to create the ball to go sideways, hit the ground, and then come out. So the ball is still going to dip in the court, but it will hit the ground, and then come out of all that. I'll do a slow motion version of this. And that ball should come out a little bit. There you go. It can have a little bit of a jump. And once you start getting more racket speed and more movement on it, and again you have to get the right angle, if you don't get the right angle it's just going to be a normal kick serve, like those kind of were. But, so what we're going to do right here is going to get these a little bit - I'm going to try to get that kicker out more. There we go. A little bit of jump out wide. A little bit of a curve. Right there, there, that was nice right there. And it jumped out, and you have that twist. So the idea is to get the ball - get them to go from here and then get them to reach out of that high back end, so the ball is actually spinning away from them a little bit more. So again, the important thing on this one, just like you're hitting a kicker, if you don't have the kicker, then don't attempt this, this is pretty tough. But you're going at an angle, not straight up, not around, more at an angle, trying to hit that angle on your serve to get this American twist to be able to jump out. So that is the American twist, good luck with it.
