A racket frame, such as for a tennis racket, has a head portion, a handle portion and a throat portion extending between and interconnecting the head and handle portions. The head portion encompasses an open region and has a first plurality of stringing holes for attaching stringing to the head portion and across the open region. The throat portion is in the form of a pair of legs in a generally V-shaped configuration. The frame also includes a second plurality of non-stringing holes defined in one or both of the head and throat portions for forming voids in the material thereof to reduce the weight and tailor the stiffness thereof in a manner which reduces axial and torsional deflections of the head portion upon striking a ball by the stringing across the open region of the head portion.
