IR spin

[GA42sDad]

If throwing a fastball with the IR mechanics, would a a 9 o'clock to 3 o'clock be the correct rotation.

DDs PC wants 12-6 spin. Hand comes over top of the ball with thumb toward C at release. If that makes sense.

a "tilted" 1-7 is what you're after.
9-3 would be more of a curveball...

When DD gets this type of spin it generally indicates that she closed her shoulders early and is holding on to the ball past the "ideal" release point. When she does this you can see a 2-3 mph drop in speed as well.

I would suspect the position of her hand at release (for I/R) is incorrect. If you've video of her, take a peak at the ball release and see if her hand was inside the ball or behind/outside of it... Also see if there is any noticeable cupping or cocking of the wrist.

As far as 9-3... that always confuses me... and I think many have a different version. You could argue 9-3 is a screw... FROM 9 TO 3 in a clockwise fashion...

I've always taken it UP the clock. start at 9 head up and around to 3... and for a curve start at 3 and head UP and around to 9... How does everyone else do this?

So is the spin sending the ball towards or away from a RHB... and is your DD a RHP...

Corlay is correct about what you're after... 7-1 tilted... From 7 Up and around to 1. LOL

Really just starting to learn the pitching mechanics this season. Was asked to coach a 16/14u rec team and trying to learn some things. Also have,a 8yrDD that wants to learn how to pitch. Just trying to learn a few things.
