Abstract: A tennis ball consisting of two identical hemispheres joined together and including small upstanding integral fingers molded into the outer surface of the ball to provide surface texture, and enable the ball to grip the surface of the racquet. Each hemisphere incorporates an integrally molded plug in the interior of the hemisphere for providing means for introducing pressure into the ball. One or both of the plugs are pierced by a needle during fabrication to provide a conduit for a needle valve inflating device. A cylindrical sphincter is placed around the inflation plug during manufacture to squeeze the plug and prevent the escape of air when the ball is inflated. The ball is manufactured by first injection molding the hemispheres and then placing the hemispheres in facing mold halves.
