Spotted: Mizuno MP-18 SC Irons
A little more than a month after Jhonnatan Vegas debuted Mizuno’s yet-to-be-announced MP-18 muscleback irons at the Masters, a cavity-back versions of the irons has appeared on the USGA’s Conforming Club List. The new irons, which are labeled MP-18 SC, are listed in both left- and right-handed versions.
It’s probably a safe bet that SC stands for “Split Cavity.” It’s also clear from the photo that the irons are constructed with Mizuno’s Grain Flow Forging Process and 1025E Carbon Steel.
A thanks to GolfWRX Member jrshelby for bringing the new listing to our attention through his forum post. Click through to see what GolfWRX Members are saying about the irons in our forums, where Outlier10 and others are already salivating over the idea of an MP-18 combo set (cavity back long irons, blade short irons).

Putters that never made it: Check out some of the best tour builds that didn’t make the cut
Arguably, the best perk of being a professional golfer on the PGA Tour is the ability to request or even just be handed pretty much any club you could think of. It happens more often than you think, usually with putters around the practice green from one event to the next. Come Wednesday, the Tour bags lining the edge of the putting surface become resting places for fallen flatsticks that never made the cut.
So let’s take a look at some of the best we’ve seen out on Tour this year that never made it to the competition. (You may notice none of Hideki Matsuyama’s custom Scotty Cameron putters made this list. There are too many.)
Let’s start with this custom Damascus Milled Odyssey Rossie made for Ryo Hisatsune. Featuring a single line and the short-slant hossel, we’ve seen plenty of Number 7 and jailbird heads featuring the Damascus Milled insert, but this is the first and only one we’ve spotted in a Rossie. Hisatsune primarily putts with an Odyssey Black Series iX #9, but we have seen him recently with a TaylorMade TP Collection SOTO, so there could be potential that the Damascus Milled Rossie could end up in the bag.
Everyone wants to be Cameron Young right now. We’ve had Justin Thomas and Tom Hoge both game the Scotty Cameron 9.5R prototype. Well, for the PGA Championship, Brooks Koepka nearly joined that list after requesting the same style of putter, with the full-length alignment line. But the Scotty Cameron reps took the request a step further and made one specially for Koepka with a Teryllium insert, similar to one in his previous Newport 2 gamers. The reason why this one didn’t go into play, though? Because it was too heavy.
Harry Hall was the third-best putter on Tour last year, so when Bettinardi made him a custom proto, you know it was going to be good. The custom BB28 blade features VDF face milling, a custom-welded single-bend shaft, and the owner’s initials – HH – on the sole of the putter. Hall, who usually games an Odyssey O-Works #7 W, has dabbled with a TaylorMade Spider Tour X already this year. Maybe there’s a chance this Bettinardi might make his bag.
Honestly, this one doesn’t need a description. It’s Kieth Mitchell’s custom Scotty Cameron Napa. One Scotty Cameron face stamp, two Scotty Dogs, two Scotty Cameron 7-Point Crowns and one Circle T. That is all. Oh, except for the Cashmere Cameron headcover.
Finally, and just for fun, how about we pour one out for this TaylorMade Spider Tour X made for Scottie Scheffler in its new torched finish. It’s unlikely we’ll see a putter change anytime soon from the best golfer in the world. In fact, he hit just two putts with it on the Harbour Town practice before going back to his trusty gamer.

In our forums, our members have been discussing their favorite major winning irons used by Tiger Woods. WRXer ‘golferdude54’ kicks off the thread saying:
“Mizuno MP 14/29. Titleist 681T. Nike Forged Blades. TaylorMade P7TW.
Among these irons that helped Tiger win 15 majors, which is your favorite in terms of looks?”
And our members have been naming their favorites and why in response.
Here are a couple of posts from the thread, but make sure to check out the entire discussion and have your say at the link below.
- SwingBlade: “I prefer the early blades he played and the more recent TM TW’s especially because after Tiger had his major behavioral setbacks, part of Nikes support payback was making Tiger play a Nike putter and cease using his beloved uniquely customized Scotty putter.”
- ProjectX: “This (Nike Forged Blades) and there’s not even a close second.”

I am very confused with Mizuno’s mode numbering first of all and now the SC addition. What is it, a cavity-back, a specked down muscle-back or a freak of nature? Can someone tell me what the successor of the MP-25 will be called? Anyway, its time for new MPs so bring those on pronto.

Like all Mizuno irons I bet with the right shaft flex and the ability to hit the sweet spot they will play fantastic….I finely got old enough and slow enough had to give up and go back to Pings as the sweet spot kept being missed along with the green.

A little bit Ping iBlade looking. Not that it matters. I wonder if there is much tech under the hood.
If not I don’t see much to get a worked up about. A design that has been around for decades.
I’m sure they feel nice and play like a blade would and I do like to break out my old blades a play them from time to time but I just don’t see anything that says I must go out and try these.

You know when the JPX 900 tour looks better than the new MP… Someone done goofed. Also the MP-66 should’ve been the new MP in the US not this. If it ain’t broke don’t fix it

They are nice but the don’t even come close to being as good as the PXG’s. I guess if you wanted a second tier club to the PXG’s you should buy the Mizuno.

you may just be the coolest person I’ve ever seen comment on here. If not you must be the smartest, since you’ve never hit the new Mizuno irons, or seen them, or held them in your hand, yet you can already comment on their performance. This is me tipping my hat to your vast knowledge!…. and in case you can’t tell I’m being sarcastic.

dumdum, oops, sorry, sumsum. Ask DJ to explain the joke to you.
It’s super weird when you write a sarcastic comment but don’t recognize one yourself.
