A batting aid having a sandbag with a vertically adjustable support on its upper surface. The top of the support has a seat member with a slot in which a disc is mounted for pivotal movement about a horizontal axis. Pivoting of the disc in one direction is limited by an adjustable braking member. An inverted L-shaped rod is fastened to the top of the disc. The short arm of the rod is threadedly connected to one end of a housing, and a ball is secured to the other end of the housing. A vertically adjustable rubber stop is mounted on the sandbag in position to be hit by the long arm of the L-shaped rod when the ball is struck by a racket, bat or golf club. The rubber stop causes the disc, rod, and ball to rebound toward their original position, and the braking member completes the resetting of the ball to its original position for the next striking swing.
