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).
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.
Bud Cauley had >14 clubs in his bag when photographed prior to the Memorial Tournament.

- macedan: “Started with a hand-me-down Golden Bear set from my brother when I was in high school, never really played more than once a year or got into the game until about summer of 2017. First purchased a set of Cleveland CG4’s (I actually really miss this set sometimes, soft & not terribly large for a GI iron), moved into Nike Vapor Fly’s by the end of the year. Those lasted until spring of 18 when I decided I wanted new, so I traded them in for TM Rbladez. Honestly, although I liked the Rbladez, poor decision on my part, I think this was really about the only time so far that after a week or two I was kicking myself for not staying with what I had. Rbladez stayed with me until late last summer when I switched to P790’s and (knock on wood) I am hoping this will be my longest lasting set.”

Seen something similar years ago, but they probably feel better.

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.
