Abstract
Abstract A device for teaching baseball batting techniques in which a base (10) provides a well (12) for one of the batter's feet and an arm (14) provides a yieldable barrier that reminds the batter whenever he has stepped away from the pitcher's mound and into the arm. The arm (14) is pivoted such that it forms a yieldable barrier that does not trip the batter. The device also preferably includes a chord (20) that is adjusted to a length such that it checks the batter's swing at levels above his strike zone.
