@white_boy My thoughts exactly. No reason for kids under 15 to be throwing curveballs and other junk before their arms are fully developed. The focus is always on velocity and striking people out, which is wrong. Little Leaguers need to be throwing fastballs and changeups… people underestimate the value of a solid changepiece.
Another issue is kids PITCHING year round. Arms need rest, especially growing ones. You can play year round all you want, but you have to take care of your arm.
