YouTube notes
In this style, the pitcher brings the arm out to the side laterally (abduction). But they turn their body toward second base at the same time. This allows the pitching arm to be raised to directly overhead without the ball being outside the wrist. Any Windmill pitcher can learn this technique in 5 minutes. This is a loophole in the ASA 10 Man Modified rules. In Pennsylvania ASA this is ILLEGAL if the pitcher brings the ball above a right angle created by the hip-shoulder-ball. Since these pitchers usually stand erect, it is illegal in PA if they come above the shoulder.
