Slingshot pitching

[marina_ramsey]

I have a question about what constitutes a slingslot pitch in modified fast pitch league.

The 2005 ASA rule book states (among other things):

Rule 6 Pitching Regulations (Modified Pitch)

Section E: The pitcher must not use a windmill or a slingshot-type pitch or make
a complete revolution in the delivery.

Now, as you may imagine, in our league we have a wide variety of ideas about what
constitutes a "slingshot-type" pitch.

The rule book does not define this term although I have seen it defined in other places as
"bending the elbow AND rotating the body significantly towards first or third base. "

We have a right hand pitcher in our league who has her arm bent at the elbow on the back swing ball our to the side.
On the top of her back swing her elbow is parallel with her shoulder and the hand is up above her head
with the ball facing toward the outfield. On her delivery her elbow is tucked into her body and her
forearm is extended toward the 3rd base line. She kind of "flings" the ball into the plate to finish her delivery as her
hand curls up at toward her body.

I hope that makes some sense. Anyway, one of our umpires has said she throw "borderline" slingshot, another says she's
legal, another says she can't do that "fling" thing.

My team is wondering who is closest to correct.

So if you can't comment on this particular pitching style, could you comment on what is meant by slingshot-type pitch or
perhaps just comment on legal or illegal modified pitching.
