Abstract
A racquetball racquet having a metal frame is disclosed, wherein increased stiffness in the metal frame is provided by a grooved contact between the inner surfaces of the frame comprising the outer perimeter of the racquet and a throat piece, completing the reinforced enclosure within which the strings are arranged. This grooved contact of the throat piece with the metal frame further resists the stress and strain of contact between the racquet and the racquetball, such that the entire surface of the strings behaves in a uniform and predictable fashion.
