The inside scoop on Rickie Fowler’s oddly unique “black” Diamana driver shaft

Rickie Fowler is likely switching into a black-on-black Mitsubishi Diamana driver shaft this week that few people have ever seen before. New prototype shafts are common on the PGA Tour, so it being “unseen” isn’t a crazy phenomenon, but this one is actually around 9 years old.
If it’s nearly a decade old, then, how has no one seen it before?
Let me explain…
Fowler has been using a Cobra King F9 driver with a Mitsubishi Diamana White Board 73X shaft recently (the above photo is from a WITB we shot at the 2022 American Express). Fowler is no stranger to the shaft model, since he’s played it off-and-on since his college and early professional days. Check out his WITB from the 2014 Humana Challenge, where he was using the same shaft.
There’s been newer versions of the Diamana White Board released since the one that Fowler uses, but he’s using the original iteration. It came out in 2006, and around that time it was played by another golfer you may know: Tiger Woods.
Flash forward to the 2022 Valero Texas Open, and Fowler wanted to switch into the new Cobra King LTDx LS 9-degree driver head equipped with an original Mitsubishi Diamana White Board 73X shaft that he’s used for years. According to Mitsubishi representatives, Fowler recently switched back into the old model because he wanted something that he’s comfortable with and has brought him success in the past.
The only problem was, Mitsubishi didn’t have any stock of that particular shaft with the original graphics. They did, however, have a few old prototypes laying around from back in the day.
Fowler’s particular blacked-out Diamana White Board shaft was from a batch of shafts that Mitsubishi experimented on in 2013. The company had just acquired Aldila, and they were testing out a new laser etching machine using raw Diamana White Board shafts.
That means that the driver shaft Fowler is set to use this week is a black, laser-etched, original Mitsubishi Diamana White Board 73 X. I guess it’s not so “white” of a White Board, is it?
His version plays at a short 44.5 inches, and it’s tipped one inch.

Spotted: Amy Yang’s T.P. Mills Fleetwood putter

This week, we spotted Amy Yang with a rare putter in her bag at the 2023 Walmart NW Arkansas Championship. The putter was made by legendary putter maker T.P. Mills and the head shape is called “Fleetwood.” If you are not familiar with T.P. Mills, the company was founded in 1963 by Truett P. Mills, Sr. who wanted to make a better putter than what was available. His original putters were crafted with basic hand tools in his garage out of of carbon steel. His son David is now crafting the handmade putters after many years learning and working with his father. The company still offers the classic Softtail, Huey, Ming, 8802, and many more putters from his shop in Tuscaloosa, Alabama.
The Fleetwood is considered heel-shafted and has a wide flange that blurs the line between blade and mallet. Amy’s Fleetwood features a single sightline on the wide flange and some “snow” stamping on the top of the bumpers. Those bumpers flare up at the toe and heel, pushing weight to the outside for added stability and a balanced feel throughout the stroke. The large back cavity has some snow stamping above “My Wand” text that is stamped and filled with white paint. The topline looks slightly rounded for a softer look and blends in nicely with the width of the putter. A half-shaft offset flow neck is welded to the head while the face features a shallow milling pattern and unique “Mills” stamping near the heel.
The “Super Bullet” sole contains a large oval cavity where material is removed to dial in the desired head weight of the putter. This main cavity is in combination with two additional round cavities out at the toe and heel area. Yang’s Fleetwood is milled from Swiss-German stainless steel, as that is what is stamped into the center of the sole.
A traditional chrome steel shaft is installed and the putter is finished off with a Rosemark 1.52 MFS (microfiber silicone) putter grip in a white and teal.

My backup is a PX Blue 6A4 from like 2009 and I’m never getting rid of it. I’m still not sure my Tensei White 1k or Ventus Black are actually any better on the course.
