    Abstract: Disclosed is an apparatus comprising a set of molded plastic sections, assembled to form an improved tennis ball returner. It is suited to rest at the bottom of a tennis net, on either side. It is parabolically shaped, so as to return tennis balls toward the center of the tennis court baseline. The exposed surface is also curved, so that it converts a maximum of energy in the falling tennis ball into angular momentum.
