Most of what the internet "knows" about Jessica Pegula's setup traces back to a single retailer bundle page — which is a thinner foundation than the confidence around it suggests.
That's not a knock on Pegula or on the retailer. It's just worth saying out loud before we start, because the rest of this piece is going to do the thing we always do — translate a pro setup into something a club player can actually learn from — and the honest answer here involves more shrugs than the average breakdown.
The setup, at a glance
| Field | Value |
|---|---|
| Frame | Yonex Ezone 98 |
| String | Not publicly confirmed (commonly assumed full-bed polyester) |
| Gauge | Not publicly known |
| Tension | Not publicly known |
| Customisation | Not publicly known |
| Primary source | "Pro Player Gear Bundle" listing |
| Last verified | May 2026 |
That's the panel. Note how much of it is empty. We'll come back to why.
The frame
The Ezone 98 is the part we're most comfortable stating plainly. Pegula has been a Yonex player for years, the frame appears in her bag in broadcast pickups, and the retailer bundle that anchors most public write-ups lists the Ezone 98 as her stick. The current generation is a 305 g unstrung, 98 sq-in, 16x19 frame — Yonex's all-court answer for players who want a bit more plow than the VCore but more spin window than the Percept.
What we don't know — and this is the part most casual write-ups skip past — is whether Pegula plays a retail-spec Ezone or a customised one. The default assumption for any top-10 player should be: customised. Pros routinely add lead at 3/9 or 12, swap grommets, change grips, and shave handles to land on a specific static weight and swing weight. Yonex doesn't run a separate pro-stock mould line the way Wilson does with the H22 or Head does with TGT codes, so Pegula's frame is almost certainly the retail mould — but that doesn't mean it's retail spec out of the wrapper. The exact customisation profile isn't publicly known, and we'd rather say that than invent grams.
Her game gives us one soft clue. Pegula is a flat, early-strike, depth-and-redirection baseliner — not a heavy topspin grinder. That style usually rewards a slightly heavier, slightly more head-light setup than retail, because the ball is being driven through the court rather than brushed up the back of. If her customisation leans anywhere, we'd guess it leans there. But "we'd guess" is the operative phrase.
The string
This is where the public record gets genuinely thin. We don't have a confirmed string main, cross, gauge, or tension to publish. The retailer bundle lists hardware; it does not publish a stringer's log.
The common assumption — and you'll see it repeated across forum threads and gear blogs — is a full bed of polyester, probably a Yonex Poly Tour string given her sponsorship, somewhere in a fairly standard WTA tension window. That's a reasonable assumption. It's not a sourced fact. We've seen no stringer interview, no Stringers' Association pickup, and no on-court tension stencil photo that nails it down. If you find one, we'd genuinely like to see it.
What we can say from her game: Pegula doesn't play like someone who needs extreme low tension for trampoline pop, and she doesn't play like someone hunting maximum RPM. Her shot is compact, repeatable, and lives in the 75–80% effort band where control matters more than peak spin or peak power. That's a mid-tension polyester profile in almost any setup. Whether it's 23 kg or 25 kg, whether it's Poly Tour Pro or Poly Tour Rev, isn't something we'll pretend to know.
A small history of how we came to "know" any of this
This is the part we think is more useful than another speculative tension number.
Public knowledge of a WTA player's setup usually accretes through three channels: stringer interviews (rare, and rarer on the women's tour than the men's), broadcast pickups of the racquet bag or the on-court restring (intermittent, often blurry), and retailer "play like the pros" bundle pages (frequent, polished, and the weakest evidence of the three).
For Pegula, channel one and channel two are quiet. There's no widely circulated stringer profile, no Slam-week piece in which her stringer talks tension drops on clay versus grass. The Ezone 98 identification is solid because the frame is visually distinct and she's been a long-tenured Yonex player. Beyond the frame, most of what circulates as "her setup" can be traced back to retailer listings — the bundle being the most-cited example — which are commercial pages built to sell a bag's worth of gear adjacent to the player, not technical disclosures of her stringing log.
This isn't a scandal. It's just how the information ecosystem works. A retailer puts up a bundle. A blog cites the bundle. A forum cites the blog. A new blog cites the forum. Three years later, a specific tension number that nobody can source is in fifty articles, and everyone assumes someone, somewhere, originally knew. With Pegula, what's striking is how few of those downstream specifics there are in the first place — which is, in its own way, more honest than the situation with players whose "confirmed" tension came from a confidently wrong tweet in 2019.
So: the Ezone 98 we trust. The customisation profile, the string, the gauge, the tension — those are open questions, and we'd rather flag them as open than launder a guess into a fact.
What this tells you
The setup, to the extent we can read it, fits the player. The Ezone 98 is a sensible frame for a flat, redirecting, depth-first baseliner who relies on timing and court position more than raw racquet-head speed. It's not an outlier choice on tour, and it's not a frame that punishes a club player the way some 315 g 95-sq-in pro-stocks do.
That last bit matters if you're reading this because you admire her game and you're considering an Ezone 98. The retail frame is genuinely playable for a strong club player. It's 305 g unstrung, 98 sq-in, with a swing weight that doesn't require pro-level conditioning to repeat for two hours. Whether you'd be playing Pegula's Ezone 98 is a different question — and the honest answer is no, because her exact customisation isn't on the table for you and probably isn't on the table for us to even describe.
The broader takeaway is the one we keep landing on with pro setups: the frame model is the easy part, and it's the part the marketing wants you to focus on. The customisation, the string, and the tension are where the player actually lives — and for Pegula, that part of the record is mostly blank. Treat anyone who fills it in confidently with appropriate suspicion, including future versions of us.
Rule of thumb for tonight: if a pro-setup spec sheet has more confident numbers than it has sources, trust the frame model, ignore the tension, and string your own racquet for your own arm.
