The main frame plate is mounted on the upper end of a vertical post by a first pivot for adjustable rotation about a horizontal axis for adjusting the curvature of flight of a thrown ball. The lower end of the post is mounted on a second pivot for rotation about a horizontal axis perpendicular to the first pivot for adjusting the trajectory of flight of a thrown ball, the bearing for the second pivot is mounted on a leg supporting cup for rotation about a vertical axis for adjusting the horizontal direction of a thrown ball.
