Abstract: An apparatus for teaching a baseball or softball player batting fundamentals. The apparatus comprises a base plate, a horizontally-disposed support bracket having baseball tee supports for supporting three telescoping baseball tees. The baseball tee supports are vertically mounted on the support bracket to support the baseball tees in fixed, elevated positions above the home plate area. In a preferred, the support bracket is sized and shaped to position three baseball tees in a vertical plane, such that when balls are simultaneously placed on each of the baseball tees, a batter is permitted to selectively hit any one of three balls, without disturbing either of the two non-selected balls.
