Jon Rahm’s year may have started with a disappointing missed cut in Dubai this week, but it was the first week of two new pieces of equipment for the two-time major winner.
Since the summer of 2021, Rahm has been almost exclusive with the Rossie S form of the Odyssey. But for the start of 2025, he’s trying something different.
Beginning at the Memorial, the tournament’s brilliant Rahm took a six-shot lead after 54 holes, only to be told he tested positive for COVID-19 and had to withdraw. This was also the first time he played a special game Odyssey White Hot AND Rossie S white hot microhinged single insert nail.

He won his first major at the US Open two weeks later with a putter and later Masters 2023. It was a staple in his bag until he moved on updated version of Odyssey Ai-ONE of Rossie at the end of 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 entirely new putter shape: an Odyssey Ai-ONE #24 slant putter.
Ai-ONE #24 was a new form was introduced with the Odyssey lineup late last year and features a hammer design inspired by classic cars, according to Oydessy.
The #24 offers a much squarer shape than Rahm’s previous Rossie and has a large rectangular channel carved out of its middle. On the retail version, a large white alignment aid is painted on the channel, but Rahm’s version is the same blue as the rest of the headstock.
One commonality between the #24 S and Rahm’s Rossie S is the steep neck design, something Rahm has pulled from his TaylorMade days when he used a Spider with a steep neck.
Callaway Tour Manager Joe Toulon told GOLF.com that the unique shape of the 24 helped stretch Rahm.
“Jon has been testing the #24 since last fall,” Toulon said. “He really responded to the lines which in a subtle way helped him line up a bit better than the Rossie S.
“He’s not a big fan of alignment aids, but the No. 24 with its squarer shape versus the Rossie S gave him enough from an aiming and optics point of view that it cleaned up his starting lines quite a bit.”
