Abstract
A baseball batting practice device is disclosed as a bat having a recess formed at the large end to nestingly receive a spinning reel. The reel is oriented to pay-out a fishing line at a right angle to the bat axis, the fishing line is secured to a baseball and serves as a tether to retrieve the ball using the reel. With the tether payed out at a right angle to the bat axis, minimum resistance to the flight of the ball is observed and the distance traveled by the ball replicates that of an untethered ball.
Claims1
A baseball batting practice apparatus, comprising:
- a solid regulation baseball bat having a striking end portion;
- a ball;
- a spinning reel, having a tether retrieving spool, nestingly mounted in a receiving aperture in said striking end portion;
- a tether having one of its ends attached to said ball and its other end attached to said retrieving spool and extending directly therefrom, through a payout bore in said striking end portion of said bat, in a direction perpendicular to the longitudinal axis of said bat and in the direction of ball flight, said spinning reel having adjustable resistance to maximize the distance of ball travel;
- a plurality of weights, selectively added to the striking end portion of said bat, to compensate for weight lost from said receiving aperture, to make the swing weight the same as that of the original bat;
- a counter geared to said retrieving spool for measuring the distance of ball travel.
