c. The pitcher must not use a windup in which there is a stop, or reversal, of the forward motion.
d. The pitcher must not make two revolutions of the arm on the windmill pitch.  However, he may drop his arm to the side and to the rear before starting the windmill motion.  This allows the arm to pass the hip twice.

EFFECT - Sec. 12:
