Abstract: A pitching/throwing device comprising a first ball, a second ball, and connector for connecting the first and second balls to each other. In the preferred embodiment, the balls are standard baseballs and the connector comprises a dowel screw. During use, the student holds the device by either ball and grips the ball in the appropriate manner for the pitch being thrown. Then, depending on the pitch to be thrown, the student flips or throws the ball to another while trying to impart the appropriate rotation to the ball. Because of the changed center of gravity resulting from the interconnection of the two balls, the act of imparting the desired rotation is made easier and the rotation of the ball is readily observable. This process is performed in several steps to first focus on the appropriate wrist/hand action and then to focus on the full arm delivery. The device can also be used by the student alone, by flipping the ball into the air while imparting the appropriate rotation to the ball.
