  • Tethered ball batting practice device
    Patent number: 4964634
    Abstract: A batting practice or baseball pitching device having a bat tethered by cord with an elastic section. The cord is anchored by a primary anchor midway between the pitcher and the batter. An auxiliary anchor is coupled proximate the primary anchor to prevent the primary anchor from being propelled toward the pitcher. The ball is lighter in weight, and preferably softer, than a regulation baseball, and the elastic section of the cord is sufficiently short to permit pitching or propelling the ball by using a lean forward, lean backward pitching technique.
