Version · 5 optionsHyper Hammer 5.3 Stretch OSChange
Wilson classic for players who want power and lightness. The Hyper Hammer 5.3 Stretch OS has a 110 in² head, a 27.5 in length and weighs only 255 g strung, with balance well toward the head (8 pts HH) to keep the mass where the ball hits. The swingweight of 301, the 70 RA stiffness and the wide 25 to 28 mm beam generate a lot of power with a short swing. 16x20 pattern. It is recommended for beginners, older players and doubles players who want the ball to come off the strings easily.

The RR Score is not yet a precise figure. It summarizes the data we have today (specs and reviews) and changes as more information comes in. A low score does not mean the racquet is bad and does not reflect its technical quality: often it is just missing data or reviews. The specs combine several sources and may have discrepancies: check the manufacturer's website and the store where you buy.
Recommended for beginners only: the RR Score for this category goes up to 75. It may be great for what it is designed for, but it does not rank among the best in the sport.
Buyer reviews
Average of the ratings given at each store, weighted by how many reviews each one has.
