Using the intent of the ASA/ISA pitching rules as a guide, the following will illustrate the differences between 9-Man and 10-Man Modified pitching rules.
I have segmented the various body parts (Wrist, Elbow, Shoulder), and have included pictures to illustrate the differences between the two styles.
I will tell you that I have seen a lot, but I will never say I have seen it all.
I do not go through every nuance of the pitching rules. If you are interested, get your hands on an ASA rule book and read the rules for 9-Man and 10-Man Modified Pitching.
NINTY FIVE PERCENT OF THE ISSUES BETWEEN THE TWO STYLES REVOLVE AROUND THE BALL BEING OUTSIDE THE WRIST.
