Thanks for the video BM.

It seems as though the hand/wrist has no chance of pushing the ball when thrown in this manner. Would a different pitch change that?

It looks like the top of the thumb comes both forward and rolls inward. Is that a constant?

In general, does the ring finger have the same responsibilities as the index finger?

Of course different pitches required different forearm/wrist/finger mechanics.....But learning the throw the ball in this manner will increase efficiency across the board........

Understanding that is not high speed video, the minutia of detail is mimimized.

Regarding the thumb.......It is actually "coming off the ball" before it turns inward....The ball is NOT being rolled with the wrist.

Ring Finger-Middle-Index Finger is the catalyst for proper inward/downward spin...........

Would really hope to know the direction of the fold/snap/movement of the fingers and wrist during the release or 5 o'clock - 7 o'clock phase, please?

Is there ever a time when the fingers are traveling behind the ball in a downward pointing direction or is that position back to the wave?

If I was throwing a drop ball, would my fingers travel across the top of the ball and perpendicular to the pitch path? I'm visualizing topspin on a ping pong ball?

I can throw a glove snap using this motion 1/2 again as hard as a hand to the ear method, so I think I am on the path to enlightenment but an actual pitch is still in the future.

I really appreciate the last set of video because it confirmed that I still wasn't getting the motion in relation to the fingers.

So far, all I can throw sucks for the most part, so my daughters wave is safe for a while. I am excited about learning more.

Should I try pushing the ball forward after the internal rotation has made my palm facing myself?

BoardMember--Thank you for clarifying this part of the pitching motion for me. I was wrong as to how I thought the "snap" worked.

The internal rotation is part of overhand throwing, tennis serving, and golf. In fact, any time you are using your arms to generate throwing speed, there is the internal rotation. Duh, why would a pitcher in fastpitch do something different?

Thanks for beating it into my head with a 2x4.

i am sorry, i still don't get it. if our thumb is traveling from 3rd base to 1st base during release. doesn't that give us a bullet spin. i guess i am confused because it has been drilled into my head that you want a 6-12 spin. i am open minded. what i am reading and viewing makes much sense. somebody set me straight on the proper spin. thanks.

Crow-Hopper......see the following from an earlier post of mine:

Spin is 6-12 on peel drop ONLY.........

thanks board, so, say, on a fastball, a 6-12 rotation is not required? man, am i off base! i thought that is why we put the black stripe on the ball? so if i am releasing, as you are suggesting, i have a 9 - 3 ish or 8-2 spin, right? i just wanna be clear.

Rotation is NOT 2 dimensional.

For example........Describing a 6-12 straight over spin means the bottom of the ball is rotating from 6 up to 12 on a clock face, when that face is directly in front of you. Or straight over spin........

What if you rotated the clock face (horizontal axis) to the right 20 degrees, but maintained the 6-12 over spin. What would you call that?......7 to 1? 8 to 2?........

If 8-12 is accomplished in the decription above, fast ball spin is correct at approx 8-2.......

8-2 runs in a bit and doesn't "hang" in the zone........But maximizes velocity from internal rotation......
