Ai-One Rossie S

“"For me changing is a big deal, but I was given the same head design in the Rossie and I just loved how it looked, I really found that the contrast between the head and the face, helped me square the face up a little quicker through impact," Jon Rahm said of his new Ai-One Rossie S putter ahead of the Ryder Cup .”

“Rahm wasted little time putting an Ai-One Rossie S in the bag at the BMW Championship and hasn’t looked back. He’s continued to rave about the performance of the putter every chance he gets, including a recent putt at the Ryder Cup that caught his attention.”

“Quick nugget on swapping out of the Ai-One Rossie S Rahm has had in the bag since late 2023: The blue finish on that putter would dent when they put it into the loft/lie machine, creating two unwanted sight lines.”

“After a visit to the Ely Callaway Performance center last Friday, Rahm and the tour Team at Callaway noticed something about his Ai-One Rossie S.”
