Tour Driver

The ST-Z 220 is Mizuno's centered, low-spin driver from 2022, built for players who deliver the ball with enough speed and consistency to punish extra spin. The Z in the name points to where the weight sits. It's parked low and central in the back of the head, which gives you a stable, neutral flight rather than the draw help you'd get from the ST-X version. If you already work the ball both ways and don't want the driver fighting you, this is the one in the ST lineup that stays out of the way.

At 440cc the head is a touch more compact than the typical 460cc max, and you feel that at address. It looks fast and a little more player-focused sitting behind the ball, which is the point. Mizuno wrapped a carbon composite crown over a forged titanium face and used the saved weight to lower the center of gravity, so the low-spin flight doesn't come at the cost of launch. You still get the ball up, you just don't balloon it.

This is not a max-forgiveness bomber for someone who mishits all over the face. The ST-Z 220 rewards a repeatable strike and gives back speed and a penetrating trajectory when you find the middle. Miss it badly and it lets you know, the way a tour-leaning driver should.

• You have mid-to-high swing speed and spin too much off the driver, costing you carry and control in the wind.
• You prefer a neutral face that doesn't add draw bias, so you can shape shots on your own terms.
• You value a clean, slightly compact 440cc look at address over the biggest possible profile.
• You strike the ball consistently enough to give up a little forgiveness for lower spin and a more penetrating flight.

Frequently Asked Questions

What's the difference between the Mizuno ST-Z 220 and ST-X 220?

The ST-Z has its weight centered in the back of the head for a neutral, low-spin flight, so it doesn't favor a draw. The ST-X moves mass toward the heel to help fight a slice and promote a draw. Pick the Z if you already square the face or work the ball both ways, and the X if you tend to leak it right.

Is the ST-Z 220 a low-spin driver?

Yes. It's the low-spin option in Mizuno's 2022 lineup. The centered back weight, forged Beta Ti face, and carbon crown combine to keep spin down and produce a penetrating trajectory. It suits players who currently spin the driver too much rather than someone who needs help getting the ball airborne.

Is the ST-Z 220 adjustable?

It has Mizuno's Quick Switch adjustable hosel, so you can change loft and lie to fine-tune launch and start direction. There is no movable sole weight, so the neutral, centered bias stays the same no matter how you set the hosel.

Is the ST-Z 220 forgiving enough for a mid-handicapper?

It's more forgiving than a pure tour head but still leans toward the better player. The 440cc profile and low-spin design reward a repeatable strike. A mid-handicapper who finds the center consistently will love the flight, but if you miss all over the face, a larger 460cc game-improvement driver will be more forgiving.

Does the smaller 440cc head hurt distance on the ST-Z 220?

No. The compact head is about look and workability, not lost speed. The forged titanium face and CORTECH Chamber keep ball speed high, and the low-spin flight actually helps total distance for players who were spinning it too much. You give up some forgiveness on off-center hits, not raw distance on good ones.
