Racket including a metal reinforced throat section
 An improved racket includes a metal frame having a throat section and two curved portions extending in the throat section and converging to a point where the throat section connects the handle section; a metal throat piece bridging and fastened to the curved portions above the point and having two reinforcing longitudinal side flanges to form a substantially U-shaped cross-section, the metal throat piece further having two curved ends bending to abut the parts of the curved portions where the metal throat piece is attached; and a covering layer formed by injecting a plastic composite material around the metal frame and the metal throat piece.
