Mizuno, which has set the golden standard for players irons over the years, is blurring the lines between a blade iron and a forged cavity back with its new JPX-900 Tour irons. The new irons pass the eye-test for a blade, but they’re pumped up with performance features usually reserved for Mizuno’s bulkier JPX irons.
Like Mizuno’s MP iron models, which are designed for the most discerning and skilled golfers, the JPX-900 Tour irons are made from Mizuno’s Grain Flow forged 1025E Mild Carbon Steel to give golfers the familiar soft, solid feel for which Mizuno is known.
“We wanted to make the best Grain Flow Forged iron ever,” says David Llewellyn, Mizuno’s Director of R&D.
What’s different about the JPX-900 Tour irons is the more aggressive styling, which is part form, part function. The addition of Mizuno’s angular “Power Frame” to the cavity increases moment of inertia (MOI), which makes the irons more forgiving. Yet according to Llewellyn, the refined cavity-back irons should be an easy transition for its staff players, Chris Wood and Luke Donald, who currently use the company’s MP-5 blade irons.
Mizuno’s MP-64 irons, a forged cavity-back that many in the Mizuno community believe to be the best-feeling Mizuno iron in recent memory, was used as the benchmark for the acoustics of the JPX-900 Tour irons. By using the company’s HIT (Harmonic Impact Technology) system, which measures and quantifies sound frequencies, Mizuno was able to mimic the acoustics of the MP-64 irons while improving on their construction.
In terms of looks, the JPX-900 Tour irons are smaller than the MP-25 irons released in 2015, with a lower toe height and a “more modern design” than the MP-25 irons, Llewellyn says. Another note of distinction: the soles of the JPX-900 Tour irons which are thinnest ever used on a JPX model, and feature the same sole geometries Mizuno has been giving its MP irons for several generations. This design will create more versatility than ever from a JPX offering, something better players will surely appreciate.
The stock shaft for the JPX-900 Tour irons is True Temper’s Dynamic Gold AMT, which uses an ascending weight design to improve performance of each iron. In the X100 flex, for example, the 3-iron shaft weighs roughly 115 grams, while the pitching wedge shafts weighs about 130 grams. The lighter long-iron shafts help golfers hit higher-flying long-iron shots, making it easier to hit and hold greens, while the heavier short iron shafts provide added stability for greater precision.
Mizuno’s JPX-900 Tour irons, available Sept. 16, will sell for $1,199.99 in either steel or graphite. There is no upcharge for custom shafts or grips.

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.
