SPOTTED: Mizuno ST190 and ST190G drivers
Three Mizuno drivers have recently been added to the USGA Conforming Clubs list: Mizuno ST190 (9.5 degrees), ST190 HL (10.5 degrees) and ST190G. While the image links are currently unavailable on the USGA website, the ST180 and ST190G drivers have been spotted in person at the British Masters.
Judging from the photos, both drivers have Mizuno’s familiar Wave Technology — an accordion-like speed channel seen in the ST180 drivers — and “SP700 Coretech” faces.
The ST190 looks to have a fixed weight in the rear portion of the sole, while the ST190G has a “Fast Track Technology” sliding weight in the heel of the sole; judging by the labeling, that track will help golfers adjust between draw and fade trajectory biases. Surely, the Mizuno ST190 HL was not spotted out at the British Masters because one would assume it’s a “High Launch” product made for those who need more launch; that tends to be higher handicaps rather than Tour pros.
The driver being tested above looks to be equipped with a popular Mitsubishi Tensei Orange shaft. Compared to the ST180 drivers, it’s also clear Mizuno is going away from the blue color scheme to a glossy black look.
Mizuno is not commenting on details/tech at the time, so for now we are left to speculate on the drivers.
See what GolfWRX Members are saying in our forums about the ST190 drivers.
Neal Shipley was the first to admit that he enjoyed his food while in college. But since his days at Ohio State, he’s slimmed down and earned a PGA Tour Card.
That hasn’t stopped him from having fun with his wedge stampings, though it’s led to some misunderstandings.
On the 54 (degree), we have ‘Big Fudge,'” Shipley told GolfWRX. “It was supposed to be ‘Big Fridge,’ so this happened a little while ago. ‘Big Fridge’ was a nickname between my college teammates and I, with ‘fridge’ meaning stomach, a big stomach.
“We told the Ping guys to put … ‘Big Fridge’ on it, and I think maybe some bad cell service or something, and they thought I said ‘fudge,’ so they put fudge on it.”
On Shipley’s 50-degree he also continues the food theme, this time with his go-to order at the “Golden Arches,” and his stamping “DONS 7.”
“The number 7 meal, the two cheeseburger meal, that was my McDonald’s order, back when I would have McDonald’s frequently,” Shipley shared.

It’s that sense of community that drives day-to-day interactions in the forums on topics that range from best driver to what marker you use to mark your ball. It even allows us to share another thing we all love – buying and selling equipment.

I happened to catch the Mizuno rep yesterday at our local golf shop and he let me hit both of them. They look amazing and feel even better.. both seem very easy to hit and forgiving.. they are going to be unveiled in Orlando in February can’t wait to get fitted for one

Anyone else read WINE Technology on the sole?

How about WAVE Technology, you know, like the waves of the sole. I have the 180 and it is good, and very calming. hmmmmmmmmmmmmm POW.

SP700 face is suppose to be made of some high end material other OEM’s use to but stop using because it’s too expensive.

I’ve never hit a Mizuno driver (or seen one in person actually) but I think going with the black crown has to make it look better at address. I know its just a visual thing and but a blue head is a bit aggressive even if blue is Mizuno’s color scheme.
Interested to hear more though.

Mizuno drivers are so underrated. Just try one I’m sure you’ll be surprised. I went to a driver fitting, tried Callaway, TaylorMade, Ping, and others. The Mizuno ST-180 out performed all of them. Superb.

Shame about the shiny crown, will never buy another driver with a reflective crown.

Wish they would try and make their sliding weights semi good looking instead of just slapping a hunk of metal and a screw together.

Mizuno rep just visited my golf shop with these drivers today. They will be unveiled at the PGA show in Orlando. Stock shaft will be the Atmos but are saying no upcharge for any shaft they offer. They have gone away from blue, and they look really good.
