A tennis racket frame of molded plastic includes head, shaft and handle portions with the cross sections thereof, together with the characteristics of the plastic material, providing maximum flex at the upper end of the head, secondary flexing at the throat area adjacent the head, lesser flexing at the base of the head, and the minimum of flexing at the shaft adjacent to handle. Shaft apertures and texturing of the handle can be molded in at the same time that the proper cross-sectional areas of these parts are formed. The cross-sectional area of the head is T-shaped and the string apertures are bridged by guides about which the strings extend in order to reduce wear thereof.
