J.J. Spaun had the best year of his career on the greens in 2025, gaining strokes for just the second time in a season. He did it after switching to L.A.B. Golf’s Df3 putter, and his year with it was highlighted most memorably by the 64-foot putt he drained on the 18th green at Oakmont Country Club to win the U.S. Open.

With the 2026 U.S. Open just around the corner, Spaun is looking to make a surprising switch away from his center-shafted Df3 and into L.A.B. Golf’s OZ.1i HS – the heel-shafted mallet putter.

“Just something I kind of wanted to change the way the putter was looking, just a completely different look than the DF3 that I’ve been using for the last year and a half,” Spaun told GolfWRX about the swap. “So it’s just easier to line up for me with less onset looking design, and it’s just something I felt like switching it up and seeing how it goes.”

The OZ.1i HS was the first model from L.A.B. Golf, which applied the Lie Angle Balance technology to more conventional putter shapes. The company created the zero-torque concept by using a proprietary aluminum riser to place the shaft axis through the center of gravity of the putter.

The more traditional shaft placement on the OZ.1i HS allows for a full alignment line across from front to back of the putter head, without being obstructed by the shaft. It’s something that Spaun believes is “easier to aim.”

Spaun has had a mixed 2026 season so far, with a win at the Valero Texas Open, but also only making 7-of-13 cuts for the year. The Southern Californian has seen himself 155th in Strokes Gained: Putting on Tour, losing over half a shot to the field.

Along with the change in head and shaft style, Spaun is also moving into L.A.B. Golf’s stainless steel insert.

“It’s a little firmer, a little faster,” Spaun said. “I feel like my pace has been pretty weak this year, so I thought a little bit of a firmer face, maybe it would get the ball to the hole a little bit faster and just kind of see what it gives me.”

Don’t worry, though, there’s still potential for the U.S. Open-winning putter to be in the bag come Shinnecock Hills Golf Club when Spaun returns to defend his title.

“I still have the gamer, the old faithful, sticking around,” Spaun added. “So hopefully she gets a little jealous and wants to start cooperating after using the hail shafted one.”
