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.”
Specs and availability
The Mizuno ST190: driver will be available in 9.5 and 10.5 degree models, both adjustable by two degrees either way. 9.5 degree option only for left-handers.

Did Rory McIlroy inspire Shane Lowry’s putter switch?
Editor’s note: This is an excerpt from a piece our Andrew Tursky originally wrote for PGATour.com’s Equipment Report. Head over there for the full article.
The timing of Lowry’s putter changeup was curious: Was he just using a Spider putter because he was paired with McIlroy, who’s been using a Spider Tour X head throughout 2024? Was Lowry just being festive because it’s the Zurich Classic, and he wanted to match his teammate? Did McIlroy let Lowry try his putter, and he liked it so much he actually switched into it?
Well, as it turns out, McIlroy’s only influence was inspiring Lowry to make more putts.
When asked if McIlroy had an influence on the putter switch, Lowry had this to say: “No, it’s actually a different putter than what he uses. Maybe there was more pressure there because I needed to hole some more putts if we wanted to win,” he said with a laugh.
To Lowry’s point, McIlroy plays the Tour X model, whereas Lowry switched into the Tour Z model, which has a sleeker shape in comparison, and the two sole weights of the club are more towards the face.
Lowry’s Spider Tour Z has a white True Path Alignment channel on the crown of his putter, which is reminiscent of Lowry’s former 2-ball designs, thus helping to provide a comfort factor despite the departure from his norm. Instead of a double-bend hosel, which Lowry used in his 2-ball putters, his new Spider Tour Z is designed with a short slant neck.
“I’ve been struggling on the greens, and I just needed something with a fresh look,” Lowry told GolfWRX.com on Wednesday at the 2024 Wells Fargo Championship. “It has a different neck on it, as well, so it moves a bit differently, but it’s similar. It has a white line on the back of it [like my 2-ball], and it’s a mallet style. So it’s not too drastic of a change.
“I just picked it up on the putting green and I liked the look of it, so I was like, ‘Let’s give it a go.’”

Webb Simpson equipment Q&A: Titleist’s new 2-wood, 680 blade irons, and switching to a broomstick Jailbird
With seven career wins on the PGA Tour, including a U.S. Open victory, Webb Simpson is a certified veteran on the course. But he’s also a certified veteran in the equipment world, too. He’s a gearhead who truly knows his stuff, and he’s even worked closely with Titleist on making his own custom 682.WS irons.
On Wednesday at the 2024 Wells Fargo Championship, I caught up with Simpson to hear about his experience with Titleist’s new prototype 2-wood, how Titleist’s 680 Forged irons from 2003 ended up back in his bag, and why he’s switching into an Odyssey Ai-One Jailbird Cruiser broomstick putter this week for the first time.
Click here to read our full story about Simpson’s putter switch on PGATOUR.com’s Equipment Report, or continue reading below for my full Q&A with Simpson at Quail Hollow Club on Wednesday.

GolfWRX: It seems like you’ve been a little all over the place with your irons in the past six months or so, and now going back to the 680’s. Is that just a comfort thing? What’s been going on with the irons?
Webb Simpson: Titleist has been so great at working with me, and R&D, on trying to get an iron that kind of modernizes the 680. And so the 682.WS took the T100 grooves, but kinda took the look and the bulk and the build of the 680’s into one club. They’re beautiful, and awesome looking. I just never hit them that well for a consistent period of time. It was probably me, but then I went to T100’s and loved them. I loved the spin, the trajectory, the yardage, but again, I never went on good runs. Going through the ground, I couldn’t feel the club as well as with the blade. So last week, I’m like, ‘Alright. I’m gonna go back more for…comfort, and see if I can get on a nice little run of ball striking.’
So that’s why I went back.

OK, that makes sense. I know you had done some 2-wood testing recently. Is that in the bag right now?
It’s like day-by-day. I used it at Hilton Head every day. Valero, I used it one round. And this week, me and my caddie will do the book every morning, and if it’s a day where we think we need it, we’ll just put it in and take the 3-wood out. I love it because it’s a super simple swap. Like, it doesn’t really change much.
Yeah, can you tell me about that club? I mean, we don’t really know anything about it yet. You know? I haven’t hit it or anything, obviously.
It has grooves like a 3-wood. Spin is perfect. And it’s honestly, like, everything is in the middle of a 3-wood and driver number. Trajectory, spin, carry, all of it. So, a Hilton Head golf course is almost too easy to talk about because, you know, there, so many holes are driver 3-wood.
Valero, our thinking was we had two par-5’s into the wind, and we knew that it would take two great shots to get there in two. So instead of hitting driver-driver, we just put it in. And I used it on those holes.
Hilton was a little easier because it was off-the-tee kind of questions. But Colonial will be a golf course where, you know, there’s a lot of driver or 3-woods. It’s kind of like a backup putter or driver for me now. I’ll bring it to every tournament.
So it’s, like, in your locker right now, probably?
Well, it would be. It’s in my house [because Webb lives near by Quail Hollow Club, and is a member at the course.] It’s in the garage.
Oh, yeah, that’s right. Do you know what holes you might use it out here if it goes in play?
Potentially 15, depending on the wind. Second shot on 10. Could be 14 off the tee. The chances here are pretty low (that he’ll use the 2-wood). But, like, Greensboro would be an awesome club all day. I’m trying to think of any other golf courses.
There’s plenty that it’ll be a nice weapon to have.
It’s interesting, the wave of 2-woods and mini drivers. Like, it’s just really taken off on Tour, and all the companies have seemed to embrace it.
Yeah. The thing I had to learn, it took me, like, at least a week to learn about it is you gotta tee it up lower than you think. I kept teeing it up too high. You need it low, like barely higher than a 3-wood. And that was where I got optimal spin and carry. If you tee it up too high, you just don’t get as much spin and lose distance, I don’t know if that’s just a mini driver thing.
And you obviously have a Jailbird putter this week. What spurred that on?
Inconsistent putting. I’m stubborn in a lot of ways when it comes to my equipment, but I have to be open minded – I just hadn’t putted consistently well in a while. And I’m like, ‘Man, I feel my ball-striking coming along. Like I feel better; for real, better.’
If I can just get something in my hands that I’m consistent with. Being on Tour, you see it every year, guys get on little runs. I can put together four to five tournaments where I’m all the sudden back in the majors, or in the FedExCup Playoffs. You can turn things around quick out here. I’m like, ‘Man, whatever’s going to get me there, great.’
My caddie, David Cook, caddied for Akshay at the Houston Open and he putted beautifully. Then, I watched Akshay on TV at Valero, and he putted beautifully. And, I’m like, ‘I’m just going to try it.’
I’ve never tried it for more than a putt or two, and I just ordered what Akshay uses. It was pretty awkward at first, but the more I used it, the more I’m like, ‘Man, it’s pretty easy.’ And a buddy of mine who’s a rep out here, John Tyler Griffin, he helped me with some setup stuff. And he said at Hilton Head, he wasn’t putting well, then tried it, and now he makes everything. He was very confident. So I’m like, ‘Alright, I’ll try it.’”
And you’re going with it this week?
Hundred percent.
Alright, I love it. Thank you, I always love talking gear with you. Play well this week.
Thanks, man.

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
Jan 7, 2019 at 4:26 pm
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.

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? 😉

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.
