To honour one of tennis' legends,Wilson created a signature Serena Williams racquet to her exact match specifications to recognize her outstanding career. The Blade series gets a total makeover with a sleek matte black finish and green highlights. As a part of the Wilson Autograph racquet series, the SW104 Autograph Countervail has gold highlights in honour of the women's all-time Grand Slam Champion. Laser etched gold script can be found on the racquet frame including Blade word mark and Serena Williams' autograph. In a departure from past Blade 104 racquets, this racquet is 28 inches in length giving you added reach and leverage when crushing balls from all over the court. Countervail has been integrated into the frame to help dampen the vibrations at ball impact lending to more energy deeper in the match and reduced muscle fatigue. With the extremely generous 104 sq. inch head and 18×19 string pattern, this racquet is very powerful and has a lot of spin potential. The SW104's heavy swingweight delivers exceptional plowthrough for players that can handle the extra weight. While stable from all areas on the court, this racquet truly shines from the baseline and feels rock solid absorbing heavy hitters. A testament to Serena's legendary career, the Wilson Blade SW104 is a monster racquet that delivers power, spin, stability and precision.
