Mizuno ST190, ST190G Drivers put woods front and center for “iron” company
Mizuno Golf is about more than just irons; that’s the message the company is keen to drive home with its launch of the Mizuno ST190 driver and the Mizuno ST 190G driver.
In announcing its lowest spinning, most technology-packed driver in company history, with the 2019 Mizuno driver, the company seeks to position itself as one that has quietly innovated in the driver space for years, highlighting milestone technologies in the Ti100, T-Zoid, MP-001, and MP-600 in discussions around the launch of its latest drivers.
With respect to the specifics of the Japanese company’s most recent weaponry, the ST190 and 190G feature a forged Sp700Ti face (10 percent stronger than 6-4 titanium) with the company’s ultra-light Cortech structure, as well as a carbon composite crown. As with the ST180 series, Mizuno applies its Amplified Wave soleplate, which deforms on impact for better energy transfer between club and ball.
The weight of the carbon composite crown, 12 grams, allowed engineers to redistribute some seven grams of weight throughout the body of the club.
The Amplified Wave Sole effectively expands the ST190’s COR area for improved balls speeds across the clubface, according to the company, and better ball speed on off-center strikes in particular.
Mizuno fine-tuned the driver’s sound via Harmonic Impact Technology, adding internal rids for a more solid sound at impact.
Getting into the differences between the two models.
Mizuno ST190
- designed for mid to low spin with maximum stability
- features a single, factory-fixed 6g backweight that adds 300gcm2 MOI
Mizuno ST190G
- Designed for low spin
- Features Fast Track adjustability: twin seven gram weights on external tracks
- Weights can reduce spin by an additional 200rpm and allow for draw/fade biases
“The ST190 marks a total change in how Mizuno approaches wood design,” says lead Mizuno golf designer Kei Tsjui. “We now start the development process with our tour players. The tour-tested molds then become our production molds. In the case of the ST190, this produced a high-speed driver with extreme low spin for the tour, but with the capability of increasing spin for lower swing speed players.”
The first PGA Tour player to game the ST190 was big hitter Keith Mitchell.
Says Mitchell: “Driving was my best category last year – I walked into testing to do ‘Cookie’ (Mizuno, PGA Tour Manager Jeff Cook) a favor, give him some numbers and leave. It turned out to be the easiest change I’ve ever made – on the one club I never thought I would switch.”

This week, we have our Tour Photographer, Greg Moore, on the ground at the OccuNet Classic at Tascosa Golf Club in Amarillo, Texas, for the 14th event of the 2026 Korn Ferry Tour season. With that, we see some great things in the Lead Tape Report as we roll into Amarillo.
Joel Thelen
Monday Qualifier, Joel Thelen is in the field this week. He has played on the Korn Ferry Tour for a full season in 2023, and he is back in action this week. A couple of clubs caught my eye this week in his bag.
First off: His trusted Titleist 816 H2 hybrid. This club came out in October of 2015, and it still remains strong in the bag. Also, take a look at this Odyssey White Hot OG 7, putting a capital S in the 7S model. This custom neck has some impressive lean for an arm-lock-style putter. The bottom of the putter is covered in tape for optimal weighting.
Mitchell Meissner
Taking a look at Mitchell Meissner’s bag this week, we have some great lead tape coverage. Top to bottom working from fairway metals, irons, and wedges. We can see on the short irons and wedges that there is tape at the base of the grip, adding a little counterbalance. Along with that, some tape on the short irons and wedges as well. Moving to his putter, he rolls the Odyssey 7 Bird putter. Meissner putts left-handed and strikes the ball right-handed.

If you play these black mizunos you won’t go back… and your golfing buddies won’t turn their backs to you.

Another driver for future EBAY sellers….unless your a single digit or better 3 or 4 yards for $500 is a big step…almost any driver from the last 6 years or so is going to work for you.

One Day At A Time

Trying like Hell to be honest and transparent in 2019… so take this fwiw…
I handle a lot of donated clubs. Always trying to get clubs to kids, and often get 10 Adult clubs for every USKG/TourEdge/XYZ junior club. In 2016, one of the younger outside staff guys swung my 905r w/o asking and w/o knowing you don’t do that, it hit the pavement, so now I’m needing a new stick and a week later a Callaway fti 6 w/ a real fuji speeder walked in. Yeah, square headed, TINGY, and if my ST180 launched at 11 spun at 24, the cally launched at 14 spun at 31. But, in early 2017 I needed to knock out my pat, and from January 1 to April 4 I hit 90% (+/-2%) of my fwys over a 120 shot sample size. On April 4 2017 I’m plotting along and the wind kicks up to 20, gusts 27. On side by side holes I hit it 205 v 330. I was educated enough to be dangerous regarding spin OTT and about a month after the only time guys say “Now you never have to play golf again!” , the ST180 was showing up ahead of time for reasons unknown. I volunteer to be the guinea pig for a driver fitting in our Teach The Teacher program and in short time the youngest assistant pro I’ve worked with had made the most INCREDIBLE W.O.O.D. adjustment to my lead hand @ address and I see 160 ball 11.5 launch and 2224 spin. Deuces to the launch monitor , I want to watch it fly outside. It’s 253 to the net, and generally speaking your apex has to be high and if you carry the net you carry it 280. I’m swinging it at 107, so I don’t need to tell you how unlikely I was to do that, and how immediately I scribbled ST-180 tensei blue gp tv full cord on the DOG’s Christmas list. And in the entire year of 2018, I struggled off the tee so much that I would give it away to the first person that wanted it. I’m absolutely the guilty party, the Mizuno ST-180 is and was a truly best kept secret for for guys that can’t hit it left to save their lives, and admittedly I did hit the best drive of my post-arthrodesis life to date with it on the nastiest par 5 I know of in DFW, but I will NEVER ever EVER ditch a fairway finding four cylinder for a driving range heat seeking missile ever again.
Until someone asks me to hit the stick that Ping is dropping in March.
And unless the Titleist TS starts curving off the face of the Earth, I am looking forward to seeing it in my bag in 2028, just like the 905r was a welcome sight for an entire decade of golf.

I’m still shopping for 2018 drives at vastly reduced prices. If I can’t make last years models give me fantastic performance, then there is something rotten in the state of Denmark. 2017 models are okay too.

Look really good, finally ditched the blue! Excellent array of shaft options and adjustments for a reasonable price! Unheard of so far this year!

Mizuno going with a cortech face is too similar to Wilson’s new Cortex driver.
Forged MB
Jan 7, 2019 at 12:08 pm
Except for the fact that Mizuno had the Cortech face well before the Wilson Cortex was even a thought and the Mizuno is actually getting your play. Don’t see any CORrelation at all.
See what I did there? 😉

Jan 7, 2019 at 1:30 pm
Wilson the guilty party then. Copy that.

Jan 7, 2019 at 8:26 pm
It is a stupid name for a driver. Wilson really didn’t think it thru (see what I did there, about Cortex?)

So, at first I thought Mizuno waiting to release this driver at the same time as Taylormade, Callaway and PING was a mistake and that it would be overshadowed by the big boy offerings. But, after seeing the lackluster new releases from Taylormade and Callawy, I think it might work out for Mizuno. These drivers look soooo good and the stock shaft offerings are far far superior to the other’s.
