Watch
Rated highest for feel and looks; its softest dimension is forgiveness.
You're a 0-18 HCP at 85-115mph low-to-mid handicapper who wants a premium-feeling, traditionally-shaped neutral hybrid with strong ball-speed efficiency (high-1.4s smash) and a controlled traditionalist acoustic — willing to give up some max-MOI forgiveness for shape and feel.
You need maximum GI forgiveness, you want a wider loft ladder for set composition, you want a draw bias (use ST-X 220 instead), or you need 5H/6H lofts (use ST-Max 230 instead).
Pros
- Independent launch monitor: 144mph average ball speed, 226yd carry distance, smash factor in the high 1.4s
- CORTECH Chamber (TPU-damped stainless weight) + 1.9mm MAS1C steel face — engineered ball-speed engine
- Slightly smaller pear-shape footprint — appeals to the eye of the traditionalist
- Low-pitched, metallic snap with below-average volume — premium traditionalist-friendly acoustic
Cons
- Doesn't stand out in any specific performance category — distance, accuracy, or forgiveness; ranked 14th overall in 2023 hybrids testing
- Forgiveness tilts toward slightly better players — smash dips to low 1.4s on bigger misses
- Only 2 loft heads (3H 19° + 4H 22°) — narrowest loft ladder in the 2023 Mizuno hybrid family
- No movable weight system — adjustability limited to ±2° Quick Switch hosel
By dimension
Forgiveness
SolidThe forgiveness in this club tilts it toward slightly better players, and it takes a pretty bad miss to get the smash factor below 1.4, but it does dip to the low 1.4s pretty easily. Doesn't stand out in any specific performance category — distance, accuracy, or forgiveness. CORTECH Chamber + 1.9mm MAS1C face provides some off-center retention. Average forgiveness — player-leaning profile with respectable smash retention on minor misses but explicit tilt away from max-MOI GI.
Distance
StrongBall speed on center is excellent, producing smash factors in the high 1.4s — paired with fairly high launch and mid spin, this club has a lot of distance potential. Independent testing: 144mph average ball speed and a carry distance of 226 yards. Mid-low spinning, high launching, adjustable hybrid with 3,534rpm average spin. Above-average distance — 144mph ball speed + 226yd carry + high-launch profile + high-1.4s smash deliver strong total distance.
Workability
SolidSlightly smaller than average footprint with a hint of a pear shape, which will appeal to the eye of the traditionalist. Straight, stable, and high launching tagline. ST-Z is neutral CG vs ST-X draw-biased sibling. Average to above-average workability — neutral CG + smaller traditional pear-shape head supports modest shape control vs the draw-biased ST-X.
Feel
ExcellentThe feedback from this club isn't stinging, but it is exceedingly clear. CORTECH Chamber encases a dense stainless steel weight with elastomeric TPU, taking stress from the club face and creating an additional energy source — contributing to solid impact sensation. Reviewer testing ranks well for sound, feel, looks, and likelihood of purchase. Above-average feel — CORTECH TPU-damped impact + exceedingly clear feedback, reviewer-confirmed strong feel ranking.
Sound
StrongQuality strikes generate a low-pitched, metallic snap, with volume below average — making this club more appealing to traditionalists. Reviewer testing ranks well for sound. Above-average sound — low-pitched metallic snap with below-average volume; traditionalist-friendly acoustic.
Looks at address
ExcellentSlightly smaller than average footprint with a hint of a pear shape, which will appeal to the eye of the traditionalist. Reviewer testing ranks well for looks. Mizuno premium black aesthetic with waffle crown. Above-average address — traditional pear-shaped profile + clean Mizuno aesthetic appeals to better players.
