  • Patent number: 5088732
    Abstract: A game in which a single player strikes a tennis ball with a conventional tennis racket so that the ball is driven away from the point in which the player is standing. The tennis ball is attached to a flexible cable that includes a non-extensible section and an elastic resilient section; one end of the cable is connected to an anchorage device stationed adjacent the player. The cable is designed to pull the driven tennis ball back toward the anchorage device. If the ball is properly struck the ball will bounce one time and be in a strike zone a few inches above the flat playing surface before it returns to the anchorage device. The anchor device is a flexible bag having a zippered opening for placement of a weighty granular material into the bag.
