According to the company, Koepka chose the ZX5 over the ZX7 because he preferred the shape. As for the ball, it not only best fit his launch conditions throughout the bag, but performed well in the wind.
As for the irons, which he first put in play at the American Express tournament 10 months ago: “I just felt like the irons were going a little bit higher,” he said when asked at the 2021 Waste Management Phoenix Open, which he won, what he liked about the clubs. “The ball flight was pretty good. The way the sole goes through the turf. They don’t stick, [which is good] because I do come in pretty steep on it.”
In August 2016, Nike announced it was exiting the golf equipment business. With that, its tour staff suddenly were equipment free agents. Among them was Koepka, a talented player but with only one win to his credit. In the ensuing five years as a free agent, Koepka went on to win seven more times, ascend to No.1 in the world in 2018 and capture four Major championships (two US Opens and two PGA Championships). Now he’ll try to build on that résumé with some new sticks in the bag.
