Abstract
Abstract A tabletop baseball game including a replica of a baseball field and a diamond which is constructed with plastic tubing and bases joined by connectors. A ball-hitting mechanism and a ball-positioning and supporting wall are provided as part of home plate. The ball-hitting mechanism includes an arm which is pivotally mounted for rotation in an arc relative to home plate. A replica of a baseball bat is pivotally mounted on the arm for swinging motion in a path that intersects the ball when it is positioned on the home plate. A spring mechanism is provided which can be tensioned by reverse rotation of the bat replica, stored by a ratchet and pawl mechanism and released by a push button to swing the bat.
