Rated as the most powerful for its category in Tennis Magazine’s 1999 Spring Gear Guide, the Wilson Hyper Hammer 5.3 Stretch OS Tennis Racquet quickly became Wilson’s most popular Hyper Carbon model. Its ideal blend of power, control and maneuverability became evident on the pro tour, as former player Lindsay Davenport and Todd Martin showcased the numerous benefits of Wilson’s newest Hammer technology. And the Perimeter Weighting System technology strategically increases the frame’s volume at the 3 and 9 positions on the racket, thus stabilizing the racket for smoother swings. At 27.5 inches, this racket provides additional leverage and more reach than a standard length racket, without impeding reaction to balls hit close to the body.
