Bryson DeChambeau uses some of the most unique irons in professional golf, but his philosophy is catching on.
The LIV Golf star uses the same length shaft from his long irons down to his wedges, which allows him to hit every shot with exactly the same swing, no matter the distance.
DeChambeau is one of the longest hitters in golf, so this allows him to use a repeatable motion despite the heavy load he puts into each swing.
Despite this, DeChambeau’s biggest weakness is his iron play, leaving many to question whether he needs to change his approach to win his third major championship.
But one major winner, inspired by DeChambeau’s US Open win in 2024, decided to join the same company as the American, and they have suggested the same philosophy to him.
Jason Day changes irons after Bryson DeChambeau inspiration
Jason Day, winner of the 2015 PGA Championship, is renowned for his elite short game. He’s been an average iron player throughout his career and had an up-and-down season with his approach play in 2025.
Grant Horvat said Day’s swing reminded him of Tiger Woods, but instead, it’s DeChambeau’s he’s been inspired by in order to improve his irons. He’s trying out a set of Avoda clubs at the Bank of Utah Championship, which DeChambeau won the US Open with.
Day explained why: “I hadn’t been hitting my irons too great at all. I decided to have a chat to my coach, Colin, and say, ‘Do you reckon we can go out and just maybe have a look?’ I don’t have an OEM sponsor, so I’m a free agent there, so I can go out and see what the best of the best is.
“Stumbled across Avoda in a way that, like obviously, Bryson had some success with it. He won with the Avoda irons at the U.S. Open at Pinehurst. But I just told my coach, just have a chat to the guys, see what they think.
“He got off the phone and called me and he goes, ‘Man, in all the years I’ve been doing this, I’ve never come across the guys the way they explained everything.’
“So we met in person. Did a lot of 3D printing of the iron head the way that I wanted to look at it. Obviously– there is a process there. After this week we’re obviously going to get back together and see what needs to kind of be improved.
“I think, currently right now I would like to see a tiny bit more offset. Try and get a little bit more turn. If that has a little bit more offset it will actually elevate the ball a little bit more in the air, which would be nice.
“And then playing graphite shafts. So instead of playing the X7s that I have played in the past, which is 136 gram shaft, I would play a 110 gram shaft, which is nice. Definitely easier on the body. And then playing the JumboMax grips as well.
“So there is just number of things from the curved irons to the graphite shafts and the JumboMax grips. The theory I think I have the same profile shaft from 60-degree all the way up to driver.
“The goal is to be able to swing, just pretty much have one swing like whatever ball flight you want, whether that’s a draw or a fade. For me it’s a draw. To go up there and hit a draw and pretty much put the same swing on it and hopefully it produces the same shot over and over again.”
It will be interesting to see how Day gets on. If we see a big improvement in his iron play, we could see a wave of players who are struggling with their approach game make the switch.
How Jason Day got on with his new irons at the Bank of Utah Championship
Day’s first round at the Bank of Utah Championship saw him shoot a three-under par 68, putting him T-21 on the leaderboard, three shots off the lead.
So far, the new irons haven’t had a positive effect. He lost 0.57 strokes on the field with his approach play during his first round in Utah. He was again bailed out by his elite short game, gaining 2.47 strokes on his putting, and 1.34 strokes around the green to stay in contention.
Day’s approach play has been the weakest part of his game in 2025, but he still gained 0.15 strokes on the field in that department. That was actually the best season he’s ever played with his irons, so it’s interesting that he’s decided to change things up now.
It’s only one round, and Day has been inconsistent on approach all season long, so don’t be surprised to see some improvement over the weekend as Day adapts to his new clubs.
