What Clubs Did Shiho Kuwaki Use to Win the AIG Women’s Open?
Shiho Kuwaki won the 2026 AIG Women’s Open with one of the most brand-consistent bags in professional golf — a near-all-Bridgestone setup built around the same yellow golf ball she’s played since childhood.

Shiho Kuwaki’s Documented AIG Women’s Open WITB
Kuwaki was documented with Bridgestone equipment through nearly every club category in the bag at the 2026 AIG Women’s Open — driver, fairway wood, both hybrids, irons, and wedges — along with a yellow Bridgestone golf ball that has become part of her identity on tour. Her putter is the one genuinely unresolved detail, covered separately below.
Driver: Bridgestone BX1LS, 9° — Mitsubishi Diamana BB, 53g, S
3-Wood: Bridgestone B1ST, 15° — Mitsubishi Diamana WB, 53g, S
Hybrid: Bridgestone BX2HT H3, 19° — Mitsubishi Tensei 1K Hybrid 70HY, S
Hybrid: Bridgestone BX2HT H4, 22° — Mitsubishi Tensei 1K Hybrid 70HY, S
Irons: Bridgestone 241CB, 5-iron through pitching wedge — Nippon N.S. Pro 850GH, S
Wedges: Bridgestone Biting Spin 2 (48°, 52°), Bridgestone Biting Spin prototype (58°) — Nippon N.S. Pro 950GH, S
Putter: Reported as a Piretti GSS Tour Only; some sources instead list an Odyssey White Hot OG 2-Ball
Golf Ball: Bridgestone Tour B XS, yellow
Confirmed as documented at the 2026 AIG Women’s Open. This bag reflects a mid-season expansion — her early-2026 setup carried irons only from 7-iron through pitching wedge.
Driver
The driver in the bag for her breakthrough major victory: Kuwaki’s Bridgestone BX1LS was documented at 9 degrees with a 53-gram Mitsubishi Diamana BB shaft in stiff flex at the 2026 AIG Women’s Open. The combination gives us a documented look at the specifications she had in the bag for a major-championship win, but it should not be treated as a fitting template for recreational golfers.
Should Your Driver Match Her Setup?
Not automatically — the right loft and shaft weight depend on your own swing speed and tempo, not a tour player’s specifications.
Fairway Wood & Hybrids
Instead of carrying a traditional long iron, Kuwaki’s bag runs two hybrids through the top of the set. Her 15-degree Bridgestone B1ST 3-wood was documented with a Mitsubishi Diamana WB shaft, also at 53 grams stiff — matching her driver’s shaft weight for a consistent feel through the top of the bag.
Below that, she was documented with two Bridgestone BX2HT hybrids — a 19-degree H3 and a 22-degree H4 — both on Mitsubishi Tensei 1K Hybrid 70HY stiff shafts. The two-hybrid configuration provided an alternative to carrying a traditional long iron in both of those loft positions and may have offered more predictable launch through the top of the set.
Irons
The irons she expanded before winning the AIG: Kuwaki’s championship-week set was Bridgestone 241CB from 5-iron through pitching wedge, on Nippon N.S. Pro 850GH stiff shafts.
That’s a real change from earlier in the season — her setup at the Daikin Orchid event carried the 241CB only from 7-iron through pitching wedge, relying on her hybrids to cover the longer distances. By the time she won at Royal Lytham, the iron set had expanded down to the 5-iron, changing the transition between her hybrids and the iron portion of the set.
Would a Compact Cavity-Back Fit You?
The 241CB rewards centered, consistent contact. If your iron game needs more forgiveness on off-center strikes, a different iron profile may suit you better.
Wedges
Two retail wedges and one prototype: Kuwaki was documented with two Bridgestone Biting Spin 2 wedges at 48° and 52°, plus a 58-degree Biting Spin wedge that Bridgestone’s own player page confirms is a prototype — not yet a retail model. All three were documented with Nippon N.S. Pro 950GH stiff shafts, keeping a consistent feel from the irons through the scoring clubs.
Putter
The only club in the bag where documented sources still disagree: Kuwaki is reported to have used a Piretti GSS Tour Only putter at the AIG Women’s Open, though some equipment coverage instead lists an Odyssey White Hot OG 2-Ball. This page will update to a single model once that’s clearly confirmed.
The Yellow Ball Behind “Yellow Baller”
Kuwaki was documented using a yellow Bridgestone Tour B XS during her AIG Women’s Open victory — and it’s become part of her identity on tour. She’s nicknamed the “Yellow Baller,” and told Today’s Golfer directly: “I’ve been using a yellow golf ball pretty much since I started.” It isn’t a one-tournament choice; it’s a consistent, personal preference that predates her AIG Women’s Open win.
Should You Play a Yellow Ball?
Within the same golf-ball model, color does not change the ball’s designed compression, spin, or flight characteristics. The choice mainly comes down to visibility and personal preference. The right ball for your game still comes down to your own speed, launch, spin, and short-game feel.
How Her Bag Changed During 2026
The clearest documented change is the iron set: at the Daikin Orchid event earlier in the season, Kuwaki carried the 241CB only from 7-iron through pitching wedge. By the AIG Women’s Open, that had expanded down to the 5-iron — a shift that likely tightened the gapping between her hybrids and irons ahead of major championship season.
