JJ Spaun’s late charge at the BMW PGA Championship was built around some exceptionally tidy iron play. Here are the Srixon irons, Cleveland wedges and Z-STAR DIAMOND ball he trusted at Wentworth.
JJ Spaun’s introduction to the BMW PGA Championship could hardly have gone much better.
Making his debut at Wentworth, the American produced a ferocious closing run to claim his first Rolex Series title and another sizeable trophy in a season already containing plenty of evidence that his game travels rather well.
And if you are interested in what was actually doing the work inside the ropes, the most revealing part of Spaun’s winning equipment setup sits firmly at the scoring end of the bag.
Spaun used a combination set of Srixon ZXi5 and ZXi7 irons, three different Cleveland Golf wedges and the Srixon Z-STAR DIAMOND golf ball as he attacked Wentworth’s pins and turned the championship in his favour late on Sunday.
The equipment story was particularly difficult to miss at the par-three 14th.
Spaun fired his approach to within five feet of the hole and converted the birdie, beginning the closing surge that carried him towards the title.
That is rather a convenient time for your irons to behave themselves.
The Srixon combo set behind Spaun’s iron play

Spaun does not use a single iron model throughout the set.
Instead, his configuration combines a Srixon ZXi5 4-iron with ZXi7 irons from 5-iron through pitching wedge.
It is the sort of blended arrangement increasingly familiar at elite level: a different solution at the long end of the set while retaining the preferred characteristics of another model through the scoring irons.
For Spaun at Wentworth, the important bit was not the theory but the outcome.
His iron play gave him the opportunity to attack flags during the tournament’s decisive stretch, with the shot into the 14th providing the clearest example. With the championship finely balanced, he produced an approach that finished inside five feet.
One swing later, the momentum had begun to shift.
Three Cleveland wedges, three different configurations
Spaun’s wedge setup is equally interesting because there is no insistence on keeping everything within one model family.
He carried:
- Cleveland Golf RTX ZipCore — 50°
- Cleveland Golf RTZ — 54° Full
- Cleveland Golf RTX 6 ZipCore — 60° Low
That mixture gives us considerably more to inspect than the familiar sight of three identical wedge heads with different lofts stamped on the sole.
Spaun had three lofts covering his scoring and greenside work, while the supplied specifications show different models and sole configurations being used to fill distinct roles.
It is a proper tour-player setup: not especially concerned with making the bag look neat for a photograph, considerably more concerned with having the right club when somebody hands you a scorecard.
Why the Z-STAR DIAMOND mattered at Wentworth
Spaun also played the Srixon Z-STAR DIAMOND golf ball throughout his victory.
Srixon positions the ball around a blend of distance, control and greenside performance, and Spaun trusted it alongside his iron and wedge configuration on a week when precision into Wentworth’s greens became particularly important.
There is always a temptation with a tournament-winning WITB to credit the equipment with rather more agency than the man swinging it.
The clubs did not hit the shot into 14. Spaun did.
But when a player attacks a flag under Sunday pressure and sends the ball inside five feet, golfers are understandably interested in exactly what was involved.
In this case: a Srixon iron and a Z-STAR DIAMOND.

Srixon Z-STAR DIAMOND
This is the confirmed Srixon and Cleveland equipment supplied from Spaun’s winning setup rather than a complete club-by-club inventory of everything in the bag.
Spaun is also currently gaming a 34-inch charcoal DF3 with a 70-degree lie angle, 2 degrees of shaft lean and a L.A.B. x TPT Golf graphite shaft.
Another substantial title for Spaun

The equipment naturally receives extra attention because of the company Spaun keeps in his trophy cabinet.
His Wentworth victory adds a first Rolex Series title to a growing collection and came with the sort of closing performance that makes a WITB considerably more interesting than a simple list of model names.
Spaun summed up the wider significance of the victory afterwards:
“It means so much. I’ve kind of blossomed into this player I never thought I could be, taking my game across the world, and more specifically here in England. It‘s a place that’s dear to my family’s heart; we vacation here quite a bit.
The stars kind of aligned this week for me to come out on top, and I’m just grateful to have the opportunity. I gave myself a chance and came out with a win.”
Wentworth provided another sizeable test of the player Spaun has become.
His Srixon ZXi irons, Cleveland wedges and Z-STAR DIAMOND were along for the rather profitable ride.
