Titleist 620 irons: Classics refined for the modern player



Some irons need no introduction.

For decades, the number 600 has been synonymous with classic forgings from Titleist. Blades and cavity backs that have found their way into the bags of the world’s best and golfers looking for the ultimate experience in shotmaking and feel. Be it the 660, 670, 680, 681, or 690, a set of these in a golf bag usually meant one thing—look out!

These timeless designs evoke memories of well-struck shots and golf balls curving in the air at a player’s will. In homage to the legacy of those that have come before, and looking towards the future with refinements for the modern player, Titleist introduces 620 MB and CB irons.

Titleist 620 MB irons

Blades, also known as muscle backs, are the easiest style of clubs to recognize in the game. Whether it be on a shelf in a pro shop or in a Sunday bag next to the practice green, you can spot them in a second. The thing is, when it comes to the 620s from Titleist, you won’t find the initials MB on them anywhere. The reason is beyond simple in its explanation, according to Marni Ines, Director, Titleist Irons Development: “We wanted to bring this blade back to its roots and make it as clean as possible, eliminate any unnecessary markings on the hosel on the back. So we didn’t stamp it with MB. We figure it you’re in the market for a blade you don’t need to be told what one is.” As I said, it almost makes too much sense.

Beyond the stamping, there is more to these irons than initially meets the eye. The 620 series offers improved turf interaction throughout the set thanks to more camber and a tweaked leading edge. I realize this is something often mentioned with new releases, especially with players clubs, but there is a good reason: As modern swings are changing, so are turf conditions. The improved agronomy of modern courses means club soles especially need to be tweaked to offer maximum playability. The sharp leading edges of yesteryear are LONG gone!

In addition to the sole tweaks, there is also less sole to worry about in the short irons. Let me explain: To offer greater control of trajectory and help players “hit their proper windows,” the set has characteristics hidden in each club. The blade length is progressive from the longest iron to the shortest, the transition is so smooth that unless you set clubs next to each other, it’s quite difficult to notice. Every detail of each head was checked, double-checked, and tour validated before getting to this point. The next part of this progression is the face height, which also transitions from more shallow to tall in the pitching wedge. This is where the extra control comes from, especially in the shorter irons with a higher CG.

Titleist has taken everything it has learned from previous MB designs, and with feedback from the best players in the world, created the finest, most controllable, blade it has ever made. It will never be the most forgiving option, but I can’t blame a player of any skill level for wanting to give 620 MB irons a try.

Titleist 620 CB irons

Just like its big brother, the blade, the Titleist 620 CB has gone through a total refinement process to get to where it is today. The sole and profile have similar tweaks to the MB but in an ever-so-fractionally larger package.

Progressive blade length and face height create the same trajectory control, but what makes the CB different is that unlike the blade (or the Titleist T300 iron), it’s not a club found at either end of the spectrum, it’s within it. Data shows that more thanr 80 percent of tour players play some sort of combo set, whether it be blades to CBs, or CBs to unsupported faster-faced irons. What this means is that the CB has to hit this perfect middle ground between transition club and being its own boss.

This is what Titleist has done to complete perfection, not just with the CB but with the clubs around it. Each radius, curve, and transition slots in perfectly with the models on each side of it, this allow you as the player to pick the set the way YOU want, and not be dictated by some unpleasant look from address. The 620 CB is still 100 percent its own unique club, designed for a specific player type, but thanks to some very smart engineering it also gives you more options.

There is more than meets the eye with the long irons of the 620 CB too. Just like the T100s, the 3 and 4-irons of the CB are co-forged with tungsten in the heel and toe to keep the size small but give a serious boost to MOI and launch.

“Our ability to use co-forged high-density tungsten in such a compact blade size like 620 CB is extremely powerful, especially at the long end of the set where players need the most help with launch and forgiveness,” Marni Ines, Director, Titleist Irons Development.

This isn’t the only club in the new Titleist iron line that has gone through this reimagining. The T100 profile has been shrunk compared to the previous AP2 (its most direct club in the previous line) to be the exact same size as the CB to offer greater stability through the ball thanks to embedded tungsten. So, regardless of if you are looking to go full CB or build your own combo set, the 620 irons from Titleist give you the classic look and feel you want—with plenty of performance.

620 MB and 620 CB Specs



620 CB: True Temper Project X LZ: Mid-launch shaft that offers smooth feel, and tour trajectory for those looking to maximize control and have a smoother tempo.

620 MB: True Temper Project X: Low-launch, low-spin shaft that has been a staple on tour and in the bags of some of the world’s top players with faster tempos looking for maximum stability.


This is a new one for Titleist. Just like with the original True Temper AMT, they will be the first to offer the Mitsubishi MCA Tensei White AM2 (stands for “ascending mass”).  This new shaft is a low-launch, low-spin option for those wanting a lighter total weight and vibration dampening. The shaft will ascend two grams per club, starting at 108 grams in the PW and going to 94 grams in the 3-iron.

These options are on top of Titleist’s already extremely large selection of available shafts—including options from KBS and Nippon—many of which are available at no additional up-charge.


The new Titleist 620 irons will be available in golf shops worldwide beginning August 30, with fittings beginning August 8.

Steel: MAP $175 per club ($1,399/set of 8)

Graphite: MAP $187.50 per club ($1,499 /set of 8)

    $175 for the MB, made by hitting a black of hot metal with a hammer before grinding and polishing it. The T300 is $125 a piece, with multiple pieces and polymers, and presumably a degree of grinding and polishing.

    What gives? Aren’t blades the cheapest clubs to manufacture any more?

Phil Mickelson is nothing if not willing to experiment with his equipment



We filed this piece for’s Equipment Report. 

Two drivers, no drivers, long drivers, mini drivers, Phrankenwoods, prototype wedges, game improvement irons, blade irons, blade putters, mallet putters, lots of lead tape, no lead tape, oversized putter grips (and gripping the putter in different manners), Lefty has tried it all.

Accordingly, it was intriguing but not entirely shocking to see the six-time major champion rolling his Callaway Chrome Soft X ahead of the World Golf Championships-FedEx St. Jude Invitational with an armlock-style putter in his hand and, well, on his arm.

In recent years, Mickelson has largely stuck to some version of his Odyssey “Phil Mickelson” blade putter. Sometimes, he uses a version with a milled face. Sometimes, it has an insert. Sometimes it has an abundance of lead tape, and sometimes it has none. For Phil, green speed and feel dictate the specific setup.

In fact, he’s using a prototype version of the same 8802-style head with the 40.75-inch putter shaft, as you can see in the photos below, which are courtesy of Callaway’s Tour Content Creator, Johnny Wunder.

So, what’s going on here? Most obviously, the longer shaft (roughly 5 inches longer than standard) and the armlock grip, which appears to be a SuperStroke WristLock, is intended to sit flush against the inside of the forearm to stabilize the putter face. In short, the objective is to make it easier to get the ball started on line.

With respect to the putter head itself, Gerrit Pon, the man who builds all Mickelson’s equipment at Callaway told the company he made a prototype putter for Phil that features a center of gravity closer to the middle of the putter face, rather than the heel.

WGC-FedEx St. Jude Tour Truck Report: Phil Mickelson goes armlock, Justin Rose takes the wayback machine



I guess it’s some flavor of irony that it was a slow week at a tournament whose title sponsor is known for rapid delivery around the world.

Maybe it technically isn’t — my ninth-grade English teacher, Ms. Whalen, wouldn’t be pleased with my lack of clarity.

Regardless, there were a few abundantly apparent equipment changes at TPC Southwind.

For equipment free agent Justin Rose, who has been on the Ferris wheel of irons in recent years, it seems the ride has stopped on his 2017 TaylorMade Rose Proto irons. Maybe it was Rory McIlroy and his Rors Proto return that inspired Rosie?

Phil Mickelson’s surprise armlocking was the other significant story at Southwind. Lefty was spotted with a prototype PM Blade with a longer shaft and what looked to be a SuperStroke WristLock grip. More news to come on this front.

Xander Schauffele shows off the ‘ultimate bag tag’ in Memphis



The Olympic Men’s Golf winner is in Memphis this week, and unsurprisingly he’s brought his Gold Medal along for the ride.

On the grounds at this week’s WGC FedEx St Jude Invitational, Schauffele enjoyed showing off his medal, which he also amusingly made look like the greatest bag tag of all time.

As well as being called the ultimate bag tag and a hard flex, our members were also speculating that Schauffele may use the medal as a marker this week.

However extremely unlikely that is, it isn’t necessarily against the rules as although there is an implied size restriction, there is nothing definitively prohibiting Xander using his prize as a marker.

We think it’s a lot more likely the medal will be making its way into a very protected area in Schauffele’s home, though!
