Jon Rahm’s year may have started off with a disappointing missed cut in Dubai this week, but it was the first week of two new pieces of gear for the two-time major winner.
Ever since the summer of 2021, Rahm has been almost exclusive with Odyssey’s Rossie S putter shape. But for the start of 2025, he’s trying something different.
It started at the Memorial, the tournament Rahm famously took a six-shot lead after 54 holes only to be told he tested positive for COVID-19 and had to withdraw. That was also the first time he gamed a one-of-a-kind Odyssey White Hot OG Rossie S putter with a White Hot Microhinge insert.
He won his first major at the U.S. Open two weeks later with the putter and later the 2023 Masters. It was a staple in his bag until he switched to the updated Odyssey Ai-ONE version of the Rossie in late 2023 and played it throughout 2024.
But this week in Dubai, as Rahm made his season debut at the Hero Dubai Desert Classic, he changed things up with an all new putter shape: an Odyssey Ai-ONE #24 Slant putter.
The Ai-ONE #24 was a new shape introduced to the Odyssey lineup late last year and features a mallet design inspired by classic cars, according to Oydessy.
The #24 offers a much more square shape than Rahm’s previous Rossie and has a large rectangular channel carved out of the middle of it. In the retail version, a large white alignment aid is painted in the channel, but Rahm’s version is the same blue as the rest of the head.
One commonality between the #24 S and Rahm’s Rossie S is the slant neck design, something Rahm has been drawn to since his days with TaylorMade, when he used a Spider with a slant neck.
Callaway Tour Manager Joe Toulon told GOLF.com that the unique shape of the 24 helped with Rahm’s alignment.
“Jon has been testing the #24 since last fall,” Toulon said. “He really responded to the lines which in a subtle way help him line up a bit better than his Rossie S.
“He’s not a huge fan of alignment aids but the #24 with its squarer shape versus Rossie S gave him just enough from an aim and optics standpoint which has cleaned up his start lines quite a bit.”
His new build is the same 37-inch spec he’s used previously with just 2.25 degrees of loft, but the total weight of the new putter is actually five grams lighter than the Rossie.
Rahm has also inserted Callaway’s brand new Elyte Triple Diamond driver, replacing his Paradym Ai-Smoke driver from 2024. Rahm is sticking with the Ventus Black 7-X shaft he switched to last summer, ditching the Aldila Tour Green he had used throughout his professional and college career.
His new Elyte TD is a 10.5-degree head with an actual loft of 10.7 and a 57-degree lie angle. The loft sleeve is set to the N/S position. The Elyte TD features front and back adjustable weights to dial in CG and Rahm has an eight-gram weight in the forward position and a 10-gram weight in the rear.
The shaft remains the same setup as last year with the Ventus Black 7-X tipped one inch and cut to a final playing length of 45.25″ and a final swing weight of D2. He is also sticking with the same GolfPride New Decade MultiCompound grip he’s used his entire career, with one wrap of taper underneath.
While Rahm opened his week with a three-under 69 on Thursday, he backed up Friday to miss the cut after a five-over 77. It’s not the start to the season he likely wanted, but it’s definitely worth tracking if he makes any adjustments to two of the most important clubs in the bag before his next start.
