Titleist 620 MB, CB, and T100 irons to debut at U.S. Open
It is always said that the U.S. Open is the ultimate test of skill and patience for a player’s entire game — driving, ball striking, recoveries, and putting.
In the case of ball striking, there really is no better proving ground than the U.S. Open, and this week Titleist is seeding the new 620 MB and 620 CB Irons along with a new addition to the line – T100 irons. The seeding process is Titleist’s way of getting new clubs into the hands of players under playing conditions and we say just a few weeks ago this same process for the new TS Hybrids and driving irons.
So far, the details are vague on what the new irons have in store from our friends in Fairhaven, Massachusetts but we can make some very obvious conclusions. The new 620 MBs and CBs will be the replacement for the current line of blade and cavity backs (I realize there couldn’t be a more softball take but it has to be said).
What is interesting about these new irons is the return to the 600 branding for Titleist, which was last used in the lineup for the 695 MB and CB irons, which go all the way back to 2006. The 600 name has always been associated with some of the best Titleist blades ever made including the 670, 680, and 690s.
Looking at the first release pictures of the new 620s, it’s yet to be seen if there are any multi-material aspects to the designs, but either way, I’m sure we will find out more details soon.
Speaking to multi-material what has also been included in this announcement are the T100s. They have an obvious AP look to them but in what also appears to be a smaller package.
The Titleist AP line has been a massive success since its introduction, but if there was one tiny bit of criticism (and I’m really searching here) it would be that it was harder to seamlessly blend the CB line into the AP line for those looking to build combo sets. Again this is early speculation, but if the new T100 has a smaller profile of the new CB but with the added ball speed and MOI of an AP iron, you could be seeing a lot of the T100s in the bags of players from pros to club golfer looking for that added advantage in the longer irons and even into the short clubs
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.”

Let’s be honest, only the MBs look good, and at that – they’re probably going to be among the most unforgiving on the market.

The MBs look amazing, I don’t care for the new CB look however – last model looked much cleaner IMO.

The 620MB look gorgeous. The CBs are starting to look too busy. And the the T100 definitely look over designed. I’m not in the market, but I’m starting to get concerned where the iron lineup is going.

Was really looking forward to iteration #2 of the AP3s… wondering if that is still on the docket.
MacAllan
Jun 10, 2019 at 10:59 am
I’ve said it before but my post was deleted.
AP’s are gone and replaced with T100 (AP2), T200 (AP3) and T300 (AP1).
Jordan

Ah i guess i didnt know they were doing T200 or T300s as well. Good to know. I’m essentially just looking for a rocket 4 iron that i can hit 230 and the T200s and 300s hopefully will get me there. Thanks.

Yes! Love the return of the curved muscleback! So many Titleist staffers have gone back to using the Titleist 680’s, not surprised to see Titleist go back to that design!
I hope the T100 aren’t an AP2 replacement. The AP2’s have becoming iconic in their naming convention and it would be a bad move to go away from that.

The MB is the best looking club on the market. Love the return to the 600 classification.
Ryan, any word on if the U500 will eventually be full set to replace the TMBs?

Great question but so far no news – by the looks of it I would say not likely at the moment

Not sure if you mean Muscle Backs in general, or the 718 MB in specific when you say “MB is the best looking club on the market.” If the former, I agree. If the latter, I disagree. I’d put both the Callaway and Mizuno MBs over Titleist’s in the looks department.
