Wilson’s new D9 irons feature the brand’s lowest ever COG in an iron
Wilson Sporting Goods has officially launched the Wilson D9 irons for the 2021 season – which feature the company’s lowest-ever center of gravity in an iron.
Following on from the brand’s D7 irons, the new additions were created using Wilson’s generative design process, which uses computer modeling to simulate hundreds of variations to optimize power hole size and configuration.
The new D9 irons contain strategically positioned, urethane-filled Power Holes designed to enable maximum face flex for improved speeds. The new Power Hole 2.0 arrangements also aim to increase deflection and allow more energy transfer to the ball, across the entire face – resulting in higher ball speeds and greater distance.
The latest irons from Wilson feature the company’s lowest-ever center of gravity in an iron which aims to increase launch angles as well as delivering a steeper angle of descent for increased green-side control.
In addition, the irons contain straighter lines, a cleaner top line and an ultra-thin face compared to its predecessors, with the D9 irons combining the look of a player’s iron with the benefits of super game improvement distance technology.
Speaking on the new Wilson D9 irons for 2021, Jon Pergande, Manager of Wilson Golf Club Innovation said
“The D9 irons represents a technological advancement showcasing Wilson’s future approach to iron design and development. This software uses over 100 processor cores of computing power to analyze the sequential versions of each club design we worked through before arriving on the final D9 line.”
The steel irons are outfitted with the lightweight 80 gram KBS Max Ultralite shafts, while the graphite iterations boast MRC Tensei shafts. The D9 irons feature the new softer Lamkin Crossline Genesis grips.
The D9 irons will be available for sale on Wilson.com and in retailers starting on Tuesday, January 26th. Retail price for the D9 irons is $649.99 Steel and $749.99 Graphite.

Three Swing Challenge: Testing the Mizuno ST-Max 230 driver
GolfWRX’s resident Club Junkie, Brian Knudson, puts the Mizuno ST-Max 230 driver to the test in our new Three Swing Challenge.
Why three swings?
Many years ago, the legendary Barney Adams, founder of Adams Golf, told us this:
“My formula as a fitter was three shots only. I discounted No. 1 just because it was the first one, counted 100 percent of No. 2, and discounted No. 3, because the player was starting to adjust.”
This is in line with our experience, and we believe golfers can make a meaningful judgment about a club in just a few swings.
Let us know what you want to see in the challenge next!

Just went to Wilson’s webpage to check out the specs of these, and man those lofts are strong! A 21 degree 5-iron? Really? I know these are considered distance irons, but I would be playing mental gymnastics on the course trying to figure out what club I should hit.

I did the same and agree. Realistically, the golfer these are aimed at shouldn’t buy anything longer than a 7 iron (27*). That leaves 5 wedges (P, G, G2, S & L). This is two more wedges than irons.

Of all the Wilson irons that have been measured, the lowest Actual Vertical Center of Gravity belongs to the 1980 Wilson Reflex at .668. Second place is the 2004 Deep Red II at .677. What is the number for the D9?
Most of Wilson’s recent offerings have had high COGs, actually above the .840 center of the golf ball.

Whether or not you agree with the MPF ranking points, the actual physical measurements of the clubheads do not lie.
