Patent ID: 6896631

Claim:
A method of training a softball pitcher in the proper mechanics of pitching arm movement during an underhand pitch, said method comprising the steps of: providing a flexible flap that is both thin and pliable enough not to adversely effect the movement of a pitcher's arm if contacted by the pitcher's arm during the underhand pitch; attaching the flexible flap to one of a waistline or leg of the pitcher so that the flap extends laterally a predetermined distance from the pitcher's body on the same side of the pitcher's body as the pitcher's arm said flap having a thickness sufficient enough to prevent the flap from folding under its own weight when attached to the pitcher; and having the pitcher perform an underhand pitch, wherein said pitcher's arm contacts and passes through the flexible flap at least one time, therein providing a tactile indication to the pitcher that the pitcher's arm is within said predetermined distance of the pitcher's body during the underhand pitch.
