Abstract: A method of a player using a ball throwing device comprising a flexible but substantially non-stretchable flexible line attached at one end to the baseball or softball. The method comprises attaching the substantially non-stretchable flexible line to a non-throwing arm of a player, and using the throwing arm to throw the ball such that it travels along a path which arcs around a non-throwing side of the player to a location in front of the player where the ball may be caught.
