  • Patent number: 6290618
    Abstract: A portable ball batting practice apparatus for attachment to a pre-existing support includes an elongated member having two ends. The elongated member is attached at one of its ends, via a rotational hub assembly, to one end of a two-ended rotatable arm. The other end of the rotatable arm is secured to a ball. By employing opposing stops within the rotational hub assembly, the rotational hub assembly allows both right and left handed hitters to utilize the apparatus and produces a directed “pitch” for a user to hit. Incorporated into the elongated member is a releasable anchoring system for attaching the elongated member to the support.
