A device to teach the proper mechanics of a baseball swing is described. The device consists of a platform that the batter stands on. Set in the platform is a wheel that the batter puts his back foot on. The wheel turns 90 degrees when the batter takes his stride showing the batter the proper way to turn his back foot so that his hips and torso rotate. The batters' front foot is guided by marks to indicate the starting and the ending position of his front foot during the swing. Attached to the platform is a guide that guides the swinging bat along the proper path to make optimal contact with the ball. The guide and platform are reversible for left hand batters, adjustable for batters of different heights and adjustable for high or low and inside or outside pitched balls. |
