Abstract
A propulsion member (e.g. a bat) has an external switch and an internally disposed transistor which transmits signals when the switch is manually closed. A receiver in a tee mechanism receives the signals and causes a tee in the mechanism to move upwardly from a rest position to an operative position. As the tee moves upwardly to the operative position, an element (e.g. a wiffle ball) moves on a ramp to a supportive position at the top of the tee. When the tee is in the operative position, a player holding the propulsion member swings the member against the ball. This is helpful to young children (e.g. eight (8) years old or younger) in learning how to hit a baseball.
