Abstract: A balance platform for teaching a batter a desired shift in weight associated with the act of swinging a bat. The platform includes a calibrated support surface, a pivot leg connected to an underside of the support surface, and a support leg connected to the underside of the support surface at a rearward end thereof. When used to teach a batter to shift body weight an appropriate amount to achieve a predetermined weight distribution during the stride phase associated with a batting swing, the stance distance and average stride length of the batter is measured and is utilized to determine the desired positioning of the batter on the balance platform. The batter is thereafter positioned atop the balance platform such that a rear foot of the batter is positioned a predetermined distance behind the center of mass of the platform.

Abstract: A device for training a baseball pitcher to throw a curve ball. The device comprises a chamber in the shape of a truncated cone having a spherical grip member, such as a baseball, connected thereto. The chamber has a cavity therein within which to snugly receive a ball to be thrown. A method for practicing the motor skills associated with throwing a curve ball is also disclosed.

Abstract: A device for practicing the motor skills associated with striking a moving ball. A series of balls are successively released from a ball magazine and deflected into a batter's hitting zone. Apparatus is provided for predetermining the approximate post deflection trajectory of each ball, thereby selectively positioning each ball within the batter's hitting zone. A timing feature for signaling deflection of the ball is also disclosed.
