The real story behind the Triple Diamond
The latest episode of Tour Validated was a personal one for me. I got to sit down with my dear friend Johnny Thompson, who is the current content manager at Callaway Golf. (Yes, my old gig.) Thompson is now known for his content, but on the Tour range, he remains one of the most respected Tour fitters in golf. His wealth of knowledge and stories about working with the best in the world is endless.
We got to talking about Tour R&D – and the conversation was directed at Xander Schauffele. This is good.
Let’s get into the part of that conversation that completely blew up my text messages after the episode aired: the true story of Schauffele’s driver struggles and how it forced Callaway to establish the Triple Diamond franchise.
For the junkies who think tour players just snap their fingers and magic happens, this is your last true test.

The first struggle
When Schuaffele first arrived at Callaway, everyone thought it would be an overnight, plug-and-play fit. It wasn’t like that. In fact, that first year was absolutely grinding behind the scenes.
The truck was trying to get him into the existing stalls, going through the familiar heads of Rogue and Flash. On paper, everything looked good. If you look at the launch monitor, the ball speed was there, the launch was there, and the spin was where the computers wanted it.
But off the golf course, Schauffele was fighting it. He didn’t get his first line and fall, HUGE for him. If it is correct, it means that most of the other tiles in TrackMan are noisy. The partners know there’s more to it than that, but Tour players often feel and focus on seeing so that part is non-negotiable.
Thompson said: “It hurt, man.
Schauffele is a very precise sound player who relies on an incredibly detailed visual relationship with the face in the address. If the club doesn’t land properly, his mind subconsciously fights against it. It got to the point where they built him a custom 440cc head just to try to fool his eye, but the consistency was gone. Schauffele actually went back to his old pre-OEM player late in the year just for comfort.
An optical illusion in the face – not all numbers
So what was the real problem? Through months of collecting data and getting feedback from Schauffele and his father, Stefan, the R&D team discovered a visible contradiction in how traditional drivers were shaped.
To make a driver look attractive to many different players, standard heads often include a combination of different visual vectors:
- The bottom of the toe is slightly folded “closed” or “doubled”
- The actual face angle line is always a square
- The top row is stripped for a slightly open look
For the average young person, you don’t see it at all. But for the world-class striker looking down at the address, it was a no-brainer. When Schauffele looked at the toe, it looked closed; if he looked at the line above, it looked open. He was getting conflicting messages before he set out on his journey. If Schauffele likes the “open” look, Jon Rahm is the polar opposite, he wants it closed. That makes sense – Schauffele is primarily a golf ball drawer, and Rahmbo is a cutter.
Switching to linear design

Callaway returned to Carlsbad and spent eight months building a tour-only prototype designed to repair Schauffele’s eye.
They ditched the old parameters with a face and made the club face the line. Align the bottom line alone, the middle face vector and the top line are perfectly aligned. If you put it down, it was always PERFECT or linear. There is no deception. There are no tricks.
To track these big-line, low-spin truck heads, they stamped them with three small diamonds.
Confirmation in Maui
The validation of the entire process took place at the season opener in Maui. Xander bagged the new Epic Flash Sub Zero Triple Diamond prototype to start competing.
On Sunday, he shot a final round of 62 to come from behind and win the tournament.
With the reps (and the company) watching, seeing the club that has put you through months of work in its first week out is a total vindication. It has proven that the R&D shift works. High-speed players across the tour quickly began looking for the same line shape, and Callaway added the Triple Diamond to the lineup the following year.
Every time you see that Triple Diamond logo in a dealership today, remember: It’s there because a world-class player refused to compromise on how his driver stayed on the green.
