Hal is right she would be putting 5 -11 spin on the ball, is that is a drop curve, I don't know. What grabs me right away is the length of her stride which is nothing extraordinary by looking at just this video but what a set of levers she has..wow! Her mechanics are great as you would expect but you can't teach long and tall and as any one who has worked with athletes, some have fast twitch muscles and some don't. As coaches the best we hope for, is to get what ever potential the player has out.
