George & Lucy (ask)

I was  wondering how old I should be before I start throwing breaking balls.George
I personal feeling on this are held by most good coach's that have seen a lot of kids pitch.

Coach Swifts answer

We would like to see you hold off until puberty, so that bone growth and muscle development are starting to be there.
 
This is not to say there are not things any kid pitching can't do to be effective.  The first and foremost is to change the grip.  EX: 1 finger-1 seam fastball, 2 seam fastball, 4 seam fastball, most important change up using 3 fingers, 4 fingers all with the same arm action as that of a fast ball.
And as I have mentioned before learn to pitch to spots and situations.  To be a pitcher we have to be able to throw strike's if we can't do that then you can't pitch no matter what type pitch or how hard you throw.
