Inside Jon Rahm’s putter switch before U.S. Open win
Editor’s note: We filed this piece for PGATour.com’s Equipment Report.
His 18-foot, curling left-to-righter breaks toward the hole, eyes locked on its path, Jon Rahm raises his Odyssey Rossie S putter and unleashes jubilant fist pump as his ball dives into the darkness.
We’ve seen the highlight how many times in the handful of days that have passed since that putt clinched Rahm’s U.S. Open victory?
It’s hard to imagine after seeing the confidence and firm conviction the ball would roll inevitably into the hole Rahm displayed on Torrey Pines’ 17th and 18th greens, Sunday, that the world No. 1 only switched into the flatstick the tournament prior to the U.S. Open. It’s surprising, too, that the mid-mallet model he settled on was a significant departure from the gigantic rear-center of gravity, high MOI mallet he had been using for months.
So, how did we get here? How did Rahmbo look more like 2008 Sunday Tiger Woods on the 72nd at Torrey Pines and less like a golfer who was so frustrated with his putting he went back to the drawing board less than a month ago?
The week prior to the Memorial Tournament presented by Workday, Rahm visited with Callaway head of tour operations Tim Reed and Odyssey rep Joe Toulon at the Ely Callaway Performance Center in Carlsbad, California, to test putters. There, Rahm was most intrigued by an Odyssey Rossie S mid-mallet putter. He remained happy with the Microhinge Star insert that had been, well, inserted into his 2-Ball Ten at the PGA Championship, so Toulon and company had the Rossie built with the Microhinge.
After evaluation on SAM PuttLab and Quintic (two putting analysis systems), it was clear the Rossie performed better than the higher-MOI, rear-CG 2-Ball Ten he had been putting with since joining Callaway’s tour staff in January. And as evidenced by his barnstorming three rounds at the Memorial Tournament and his clutch putt-filled win at the U.S. Open, the Spaniard’s putting performance was indeed elevated.
For the inside story of Rahm’s Rossie S, GolfWRX spoke with Odyssey tour rep Joe Toulon.
GolfWRX: When Rahm signed with Callaway, he was using a putter that looked very much like the Odyssey 2-Ball Ten he ultimately put in the bag. It intuitively made sense that’d be his choice, but he switched to a different putter at the Memorial. Why?
Joe Toulon: When he came into our putter studio in January, he hadn’t really been putting great. He was anxious to get into something. We had, probably, 20 putters made up for him, and the whole time, we were thinking the 2-Ball Ten with the S-neck would be the winner because it was similar to what he was using coming in.
But through that process, you have to listen to what the player is saying and how they’re saying it. He was struggling with setup and how his putter sat on the ground…and he found himself fidgeting.
In his college days, he used a 2-Ball. So the 2-Ball Ten, the way it sat on the ground for him was the reason he gravitated toward that. He felt comfortable with it…and with his path, he squared it up a little bit more and hit more putts in the center of the face.
The last thing we did with that putter was change to a White Hot insert. He’s such a feel player, and he told us that White Hot felt good at impact.
So that’s what he switched to at the Farmers Insurance Open and used through the PGA Championship.

Below are the results of GolfWRX member voting for the 2025 best driver, along with the vote percentage for each club.
Best driver of 2025: The top 5
5. Callaway Elyte Triple Diamond: 6.02%
Callaway’s pitch: “For golfers looking for a fast, forgiving, yet workable driver, the Elyte Triple Diamond features a tour-inspired shape and is the preferred model by most Callaway tour players.”
You can read what other golfers are saying about the driver in the GolfWRX forums, and see our launch piece here. Shop the Callaway Elyte Triple Diamond here.
4. Ping G440 Max: 6.86%
Ping’s pitch: “The most forgiving G440 model, MAX has a hotter face to generate speed and distance, and a lighter overall system weight with a longer shaft (46″) for faster clubhead speed, higher launch and longer carries. The Free Hosel and Carbonfly Wrap crown save weight to create our lowest CG ever and increase forgiveness while contributing to a more muted, pleasing sound.”

3. Ping G440 LST: 9.53%
Ping’s pitch: “LST is an especially good fit for faster swings, offering less spin and more control with a penetrating trajectory. A hotter face, lighter overall system weight and longer shaft (46″) deliver more speed and distance while maintaining tight dispersion.”
@phizzy30: “Not a fan of Ping drivers in general, but 440 LST takes the cake. It’s super forgiving across the face for a low spin head, looks and sounds good and the ability to make it play neutral or slightly fade biased through the hosel settings is very appealing.”

2. Titleist GT3: 16.55%
Titleist’s pitch: “The GT3 Driver offers Titleist’s boldest combination of power and personalization through adjustable performance. Dial in the CG Track to your frequent contact location to make your biggest drives even bigger while taking total control over flight and shaping.”
@mrmikeac: “I’ve been Anti-Titleist for years and years and years (outside of Vokey, of course). With that being said, HOLY BEGEEZUS the GT3 driver is an absolute NUCLEAR MONSTER! This thing blew my G430 10K Max out of the water in every single category. Forgiveness is the biggest thing that stands out of me, the 3 model has always been one of the less forgiving models in the past but this GT3 can take bad shot after bad shot and still end up in the fairway, I think a ton of that has to do with the adjustability, it’s actually effective. Feel and sound is perfect, that solid crack is so addicting to hear and when you hit it out the screws this thing can absolutely bomb it. Titleist, I’m sorry for doubting you. You have converted me.”

1. Titleist GT2: 22.91%
Titleist’s pitch: “Delivering impressive distance from any impact point, the Titleist GT2 Driver extracts maximum performance through a forgiving design. Get the stability and added confidence of a high-MOI driver without sacrificing speed.”
@DTorres: “The Titleist GT2 has proven to be the best driver of the year. Packaged in a classic profile, GT2 perfectly balances performance and forgiveness while consistently being a high performer across all categories.”

Hey guys go to the full article linked. It explains the whole train. Bravo to Rahm for putter fitting until they got the right one. I am going to get fitted to my style on my next putter. I like what I use now but I can tell 2 small changes I want next.

I think you guys pulled the wrong interview. This interview speaks to his change from his spider to the two ball 10 with a whitehot face. Not the switch from the two ball to the rossie.
