Did you ever think when you those first posts on DFP that you would start a revolution in pitching?She’s only missing 2 things really. A little more relaxed Fluidity and EXTERNAL ROTATION on the way up to 9:00.
It’s a fluid drill by starting at the bottom with the ball Facing inward. As she moves up the back she should turn the ball upward as she moves to 9:00. Some kids seem to position the ball better at 9:00 by thinking “back of the hand faces the ground“ vs. ball or palm up.
On the other hand, some kids just don’t understand the motor skill of how to turn to palm up going backwards because it’s counter intuitive. Using a modified form of the magician drill where she literally throws the ball backwards as she moves up to 9:00 will help her body learn to get to palm up through an external rotation ball toss to the rear.

One of my goals was to have a framework available so parents would have a resource to teach their DDs the basics of pitching. I feel like we are about 90% of the way there. (Aside: At some point, a kid needs a PC. But, a kid pitching rec ball shouldn't have to pay $$$ to pitch a few games.)
