- a head at an upper end of the racket frame, the head defining a perimeter of a string bed comprising a plurality of cross strings and a plurality of main strings interwoven with said plurality of cross strings;
- and
- a yoke portion at a lower end of said head, said yoke portion extending between a pair of arms of a generally Y-shaped throat portion connecting said head and said handle portion of the frame, and said yoke portion curving downwardly between said arms;
- and wherein the improvement comprises:
- an elongated slot through said yoke portion, said slot having a length extending in a direction perpendicular to said plurality of main strings, at least two of said main strings passing through said elongated slot, and said slot further having a width perpendicular to said string bed, said width being substantially larger than a string diameter of said main strings, and dampening means provided in said slot.
