6-4-3 = 2
Ha! Thanks Java. Yeah left out start from the K-position - sideways to the catcher. Try it like this.
1. Stand sideways to the catcher.
2. Keeping back straight, squat like you are sitting down, not a deep squat, just enough like you are going to sit in a chair.
3. Let the ball swing back easily, ball up just like a k-drill
4. Stride out while maintaining the back straight and squat position, just like k-drill
5. Begin to throw the ball
6. When landing on stride leg firm it up. It is slightly bent because of the squat position, so it is active not stiff.
7. When stride leg lands, let the back leg through by letting the thigh rotate inwardly.
8. Whip the ball through.
The idea is to keep the back straight, therefore posture upright, by keeping the pelvis behind the knees (from a side on perspective) instead of on top of or directly above the knees. Like you suggest, I am trying to activate legs, glutes and core separately from the head, arms and shoulders, by activating them with the chair type squat. This helps get the feeling of using the legs and shows how to clear the back hip without bending over and putting the butt back. By squating, with no torso bend forward, you create a barrel to get your arm through as soon as you tuck the back leg dd ( image of barrel would be in lap with open end toward catcher and second base. So, not a deep squat. Just standing sideways, bending knees out in front of you and slightly sit back. Then do k-drill this way. This all keeps the torso and head over the center of gravity. There is no standing up as you keep your legs bent with weight of your torso in them. With your butt under you, and back straight, there is no way to lean, and the back leg is much easier to get through with the left leg active.
Let me know if I got to try again. This is what I tried, because, all high level pitchers have the back straight posture which is maintained throughout the pitch ( after the push-off). So, I start in that position and maintain it.
I'll give this a go tomorrow. Could you possibly upload a video showing how?... or is this similar to the video recently uploaded video of the florida instructor having the young girl pitch with Hannah Rogers?
