  • Baseball Batting Device
    Publication number: 20090176602
    Abstract: A baseball batting device includes an elongate lever arm having opposed proximate and distal ends. The device includes a fulcrum lowerly adjacent the lever arm for separating the proximate or distal end of the lever arm from a ground surface during use. The lever arm is rotatable about the fulcrum between a first position in which the distal end is adjacent a ground surface and a second position in which the distal end is separated from the ground surface. A downward force exerted on the proximate end moves the lever arm from the first position to the second position. The lever arm distal end is configured to support a baseball when the lever arm is at the first position and to release the baseball when the lever arm is at the second position. The fulcrum and distal end are adjustable so as to modify the path of a tossed ball.
