Pitching regulation

[chapmaja]

7/8 grade fastpitch - league modified ASA rules. The question isn't covered in the league rules.

What is the required position of the elbow and the hand of the pitching arm during the pitching motion.

I was the BU yesterday and I noticed one of the pitchers during the game had the following motion. When she would bring her arm through to release, she would tuck the elbow in towards her body with the lower arm at about a 40 degree angle out away from the body, so her hand position was well outside the elbow upon the release. My first thought was this was illegal, but I wasn't sure. Having tried the motion, I don't like the way it put pressure on the elbow.
