The Defyer is Wilson's newest spin-first line, and the 98 Pro is the tightest-strung, most control-oriented frame in that family. A denser 16x20 pattern than the wide-open patterns most spin racquets run gives it a more controlled launch while still generating real topspin. This is the version several tour players moved to when the line launched, and it's a genuine alternative to the Blade or Pro Staff for players who want spin without giving up shape on the ball.

Technology
SI3D — A flexible hoop geometry that allows the frame to bend laterally through contact, increasing dwell time on the string bed and boosting spin potential without requiring an extreme swing angle.
Torque Shaft — A reinforced throat design that stabilizes the frame head during contact, reducing flex and dead zones on off-center hits to effectively enlarge the usable sweet spot.
Airfoil Bumper — An aerodynamically shaped bumper guard that reduces drag through the swing arc, increasing racquet head speed without adding weight.
Dual Taper Beam — A variable beam profile that concentrates power and forgiveness where the ball most commonly contacts the frame.
