Abstract:
A wand is formed in a hollow cylindrical configuration. The wand has inner and outer ends. A ball has a cylindrical passageway extending diametrically through the ball. An essentially inextensible cord couples the wand and the ball. In this manner a pitcher is adapted to grasp and spin the wand to pitch the ball in a circular manner. Also in this manner a batter is adapted to swing a bat in an attempt to strike the pitched ball for batting practice.
