Navarro plays a spin-marketed frame as a flat, early-ball baseliner — and that's the puzzle worth unpacking.
The Yonex VCORE 98 is sold, in every piece of marketing Yonex publishes, as a rotational, heavy-topspin weapon. Navarro's game is the opposite shape: compact takebacks, ball taken on the rise, drives that travel through the court more than over it. So either the retail VCORE 98 is more versatile than the brochure suggests, or what she's actually swinging is a customised version that bears only family resemblance to what's on the shop wall. We'd argue both are true, and the rest of this piece is us trying to earn that claim.

A few honest notes on that table. The frame and string identity come from a retailer "play like the pro" bundle, which is the most reliable public signal we have for Navarro short of a stringer interview or a clean bag pickup. Specific tension numbers and lead-tape maps aren't out there in any source we'd stand behind, so we're not going to invent them.
The frame
The VCORE 98 retails at 305g unstrung, 16x19 pattern, 320mm balance. It's the middle child of the VCORE line — heavier and more arm-friendly than the 100, less of a control brick than the 95. Yonex's own positioning treats the 98 as the "all-court spin" option, but in practice it's the frame their flatter, more compact hitters tend to land on too. Belinda Bencic has lived in this family for years and hits about as flat as anyone on tour.
What we don't know about Navarro's specific stick is everything that actually matters at the pro level: static weight, swingweight, balance after customisation, whether there's silicone in the handle, whether the grip is built up or pallet-swapped. Pro-stock VCOREs do exist — Yonex's pro department will build to spec off a base mold — but there's no public indication Navarro is playing anything other than a customised retail layup. No leaked mold codes, no telltale grommet swaps in broadcast close-ups that we've spotted. Until we see otherwise, the working assumption is: retail VCORE 98, with weight and balance tuned by her team, and that tuning is private.
That's a meaningful caveat for a club reader. The frame on the shelf at your local shop is the same chassis. It is almost certainly not the same racquet she's hitting with by the time her stringer is done with it.
The string
Full bed of Yonex Poly Tour Pro, per the bundle listing. Gauge isn't specified in the source we're working from, so we'd guess 1.25mm as the tour-default but won't pretend that's confirmed.
Poly Tour Pro is one of the more forgiving co-polys on the market — softer than Luxilon ALU Power, more arm-friendly than RPM Blast, and known for holding tension reasonably well by the brutal standards of polyester. It's also one of the more popular strings on the WTA, which matters less for what it tells us about Navarro and more for what it tells us about the WTA: full-bed soft poly is the default, and players who want more bite tend to hybrid it with a rougher main rather than switch chassis entirely.
For a player who takes the ball early and drives through it, a full bed of Poly Tour Pro makes sense in a way the frame's marketing doesn't. She isn't asking the string to grab and spin a ball she's brushing up the back of — she's asking it to give her a predictable, slightly muted response when she's redirecting pace on the rise. That's exactly what a softer poly does. A gut hybrid would give her more pop and more comfort but less of the dead, controlled response that lets her hit through the court without the ball ballooning. A stiffer poly would give her more spin potential she doesn't especially need.
Restring cadence, tension on clay vs. hard, whether the tension drops for indoor events — none of that is in the public record we'd trust. Tour stringers will typically run 24–26kg on a frame like this for a player of her swing speed, but that's a tour norm, not a Navarro-specific number.
What this tells you
Read the setup back as a whole and the apparent contradiction resolves. The VCORE 98 isn't really a "spin racquet" in her hands — it's a 98-inch headed, 305g, 16x19 control platform that happens to be marketed for spin because that's what sells frames in 2026. The full bed of Poly Tour Pro confirms the read: she's prioritising a consistent, slightly damped response over maximum string bite. Nothing in the configuration is fighting her game. The Yonex marketing copy is fighting her game; the actual gear isn't.
On tour, she's not a particularly extreme outlier. The VCORE 98 has a healthy WTA following, and full-bed Poly Tour Pro is closer to default than exotic. What's mildly distinctive is the combination of that frame with her playing style — most of the VCORE 98's other high-profile users hit with more arc and more rotational shape. Navarro's a reminder that frame choice on tour is downstream of feel and trust, not category labels.
For the club reader: this is one of the more borrowable setups on tour, with one large asterisk. The retail VCORE 98 is a genuinely playable frame for a 4.0+ player with a clean swing — it isn't a 315g players' frame that demands a tour swing speed to activate, and it isn't a tweener that collapses under pace. Poly Tour Pro at a club-friendly tension (22–23kg, or roughly 48–51 lbs) is one of the more forgiving polys you can put in a frame. So you can get within shouting distance of Navarro's stringbed and chassis without doing yourself an injury.
What you cannot replicate is whatever her team has done to the balance, the swingweight, and the handle. That's the part of any pro setup that never makes it onto the website, and it's usually the part that matters most.
The unsettled bit
Here's the question we don't have a good answer to: does the VCORE 98 actually generate more spin than a comparable 98 from another brand in the hands of a flat hitter, or is Yonex's spin marketing essentially a story told about the frame's behaviour at extreme racquet-head speeds that most players, including some pros, never reach?
Independent spin-rate testing on identical strokes across frames is rare, and the few studies that exist tend to find that string choice and swing path dominate the variance, with frame contribution sitting somewhere between small and noise. If that's right, Navarro's choice of the VCORE 98 isn't a bet on the frame's spin profile at all — it's a bet on the feel, the flex, and the trust she's built with the chassis. Which would mean the most interesting thing about her setup is how little the marketing category actually predicts what's in her bag. We don't think that's fully settled, and we'd be careful with anyone who told you it was.
