Pitching Mechanics / Illegal Pitches / Teaching Children Properly From Day 1

[LoRafter]

I am on my third season of coaching my daughter's 6-U now 8-U softball teams. I am a bit frustrated with the mechanical flaws that are being taught at clinics and by other coaches. I could care less if the umpires call players on certain techicalities; however, I want to see the kids learning proper mechanics from the get-go.

My main issue/question right now is with the pitching mechanics of a girl on an opposing team/league. This pitcher starts her rotation with the ball in her glove then swings her arm back past her hip then forward until she has the ball back to her glove fully extended above her head, then with no pause she brings the ball back down past her side then forward again to the traditional windmill rotation.

I think this description may be confusing. I apologize if it makes no sense.

In any event, my understanding has always been that you can only cross your hip on the back swing then through the windmill until the release at the hip. Please correct me if I am mistaken.

Thank you!!
