    Abstract: This invention relate to a batting practice apparatus wherein a ball toss-up device is positioned remote from a caged target. The ball toss-up device includes a vertically extending cylindrical tube having therein a cylindrical piston for movement along the longitudinal axis thereof. A coil spring is placed between the lower end of the piston and the bottom of the tube for biasing the piston upwards. A pedal arm is extended through a longitudinal slot in the wall of the cylinder and having one end attached to the piston, whereby a player can manually urge the piston downward against the bias of the spring. A releasable latch is provided to hold the piston in the downward position until manually released by a player to cause a ball to be projected into the air to be hit by a player. An inclined trough is provided between the target and the ball toss-up device for automatically guiding balls to the toss-up device after hitting the target.
