Bryson DeChambeau has tense exchange with reporter over his 3D-printed iron after horror moment

Bryson DeChambeau had a frosty exchange with a reporter shortly after he shot a four-over-par round of 76 on day one at The Masters.

DeChambeau, who finished tied for fifth at Augusta National last year, was on even par after 10 holes after hitting a bogey on the second hole and a birdie on the third.

But his round began to derail when it took him three attempts to get out of the bunker on the 11th hole.

The 32-year-old carded a triple bogey and, while he got a shot back on the 17th, dropped shots on 16 and 18 to end on four-over-par.

DeChambeau, who is one of the more charismatic figures on the golf circuit and has 2.65 million YouTube subscribers, was not in a particularly great mood after his round ended.

And he appeared to take issue over a question about his 3D-printed iron, which is new for Augusta.

DeChambeau confirmed to ESPN that he had built the club himself, noting that it had 'almost a bubble on the bottom with more head weight' and that he had been building it for years.

"It's finally ready," he said.

Unsurprisingly, 'The Scientist' was quizzed about the iron in his post-round interviews after round one.

"Good. It was great on [hole] seven. I hit a good second shot, and one didn't hit it off the left. Irons are still something I have to work on," he said. "I only hit it once today.

"It prints in eight hours, machines in another three or four hours. Then you have to cut grooves in it, and do a bunch of other stuff. So you can have something within a day and a half."

When asked if he could have another iron ready for the weekend if he needed it, he scoffed before replying: "No! It has to be USGA-conforming. There's a whole process you have to go through."

DeChambeau, who won the US Open in 2020 and 2024, has finished in the top 10 at The Masters in the previous two years but, prior to then, hadn't achieved significant success at Augusta.

His analytical and scientific approach to the game - hence the nickname - has meant he has experimented with various golf clubs over the years, and revealed last month that he had settled on his newest innovation during a tournament in South Africa.

"I was trying wedges," he explained. "So I was going quite a bit down a rabbit hole there and figured a couple cool things out. Hopefully it helps this week.

"Then I am working on irons, building irons, building a driver. So we'll see where it goes, we'll see where it takes me.

"All I could say now is, if I don't put them in the bag, it's my fault now."
