Abstract:

A baseball training aid for use by a batter to improve his swing. The training aid comprises a frame defining a rectangular loop, and an elongated handle attached to the loop and extending outwardly therefrom. A net is secured to the loop. The handle is angled at a point adjacent to the frame so that the plane of the frame is at an angle to the intermediate portion of the handle. The handle has a grip on its remote end, and the handle is also angled at that end so that a first portion of the grip at the extremity of the handle extends at an angle to a second adjacent portion of the grip and to the intermediate portion of the handle, so that the plane of the frame is displaced from the angled extremity of the handle. The batter grasps the first portion of the grip with one hand which extends over the corresponding angle, and grasps the second portion of the grip with his other hand.
