Ben Shelton Serve String Setup: Tension And Gear Breakdown

Ben Shelton's explosive left-handed serve frequently breaches the 140 mph mark, terrorizing opponents across the ATP Tour. While raw athleticism and an aggressive kinetic chain drive that power, his equipment choice plays a crucial engineering role. Shelton relies on a specialized polyester string configuration paired with a player's frame to harness control without sacrificing ball speed.

At the center of the discussion is his choice of Yonex Poly Tour Strike and Yonex Poly Tour Pro. Rather than relying on a standard off-the-rack setup, his string bed is tailored to handle extreme racket head speed, offering a mix of control, durability, and snapback that transforms raw muscle into accurate, heavy serves.

The Core Equipment: Frame Meets String

Shelton plays with the Yonex EZONE 98, a popular frame known for offering a blend of stability, a generous sweet spot, and a slightly crisper response than plush control frames. To tame the inherent power of the EZONE 98, he turns to monofilament polyester strings. Polyester does not offer the soft pocketing of natural gut, but it provides vital control for players who swing out aggressively.

His hybrid setup utilizes Yonex Poly Tour Strike in the mains and Yonex Poly Tour Pro in the crosses. Poly Tour Strike is a firm, control-oriented polyester string designed to maintain tension stability during heavy hitting. Poly Tour Pro is slightly softer and more forgiving, providing a touch of comfort to an otherwise rigid string bed.

Decoding the Tension Numbers

String tension dictates how long the ball stays on the string bed and how much energy is transferred back to the ball. Shelton strings his racquets at high professional tensions—typically hovering between 54 and 57 lbs (approximately 24.5 to 25.9 kg) depending on the surface and conditions.

Unlike many players who drop tension to maximize free power, Shelton utilizes a higher tension to keep his flat bombs and heavy slice serves inside the baseline. Because he generates massive racquet head speed on his own, lower tensions would cause the ball to trampoline, flying long. High-tension polyester acts like a seatbelt for his groundstrokes and serves, providing predictable launch angles.

The Hybrid Logic

The interplay between his main and cross strings dictates the feel of his serve:

• Mains (Poly Tour Strike): Placed in the vertical position, these strings dictate directional control and spin potential. Strike resists deformation under heavy impact, meaning the ball goes precisely where he intends.
• Crosses (Poly Tour Pro): Placed horizontally, these strings support the mains. Interestingly, tour reports show him sometimes stringing his crosses slightly higher than his mains to balance the stiffness of the bed and enhance pocketing.
• Snapback Effect: Monofilaments slide against each other during impact, snapping back rapidly to impart heavy rotation on kick serves out wide.

Replicating the Setup: Is It Right For You?

Copying a professional tennis player's gear verbatim is often a recipe for tennis elbow. Shelton's high-tension polyester configuration is optimized for elite athletes with fast, flawless mechanics. If a recreational player with a moderate swing speed drops a stiff polyester string into a stiff frame at 57 lbs, the shock absorption plummets, transferring stress directly into the wrist, elbow, and shoulder.

If you want to test a similar poly setup safely, consider these steps:

1. Assess your swing speed: Only use full beds of firm polyester if you generate fast, long strokes.
2. Drop the tension: Lower the tension by 4 to 6 pounds compared to Shelton's spec to protect your joints, landing closer to 48-52 lbs.
3. Try a hybrid: Pair a durable control string in the mains with a softer multi-filament or softer poly in the crosses to retain arm health.

Frequently Asked Questions

What racquet does Ben Shelton use?

Ben Shelton plays with the Yonex EZONE 98, a 98-square-inch frame tailored for advanced players seeking a mix of power and precision.

Why do pros use polyester strings?

Polyester strings offer low power and high durability, allowing professional players to swing at maximum velocity without losing control over the ball's trajectory.

How often does Shelton change his racquets during a match?

Like most touring professionals, Shelton has his racquets freshly strung before every match and often takes new frames at the ball change (every 7 to 9 games) to maintain exact tension consistency.

Does string tension affect serve speed?

Yes, but inversely to what many expect. While lower tensions can increase ball exit speed via a trampoline effect, they sacrifice control. Higher tensions require more physical effort from the player to generate pace, but they allow for cleaner, harder swings without fear of overhitting.
