ABSTRACT:
A pitching machine contains a pitching arm that vertically rotates at a speed of about 5 to 15 rpm, picks up a ball from the ball cradle at a pick-up point in its rotation, and then releases the ball at a release point in its rotation to provide a first velocity component to the ball. The pitching machine also contains a wheel that vertically rotates at a speed of about 300 to 3000 rpm. The wheel is positioned at the release point of the pitching arm to provide a second velocity component to the ball and to pitch the ball at an initial launch angle.
