In the world of professional golf, the tiniest tweaks can lead to the biggest breakthroughs. And when it comes to Wyndham Clark, the defending champion at the Truist Championship, his iron setup might just be the most fascinating story on the equipment truck this week.
From 620 CB to T100—and Back Again (Sort of)
Let’s rewind for a second. When Clark won three PGA TOUR events—including the 2023 U.S. Open—he did it with Titleist’s 620 CB irons in the bag. Then came a switch. Seeking lower spin and more distance, Clark transitioned to the Titleist T100 irons about a year ago.
However, with changes to his golf ball and swing, Clark wanted something more specific: the crisp, clean look at address from the 620 CBs, with the launch and spin profile of the T100s. With that request, Titleist Tour rep JJ Van Wezenbeeck and the Tour team got to work on building a Frankenstein set on the fly.
Enter the “Loft Shift”
Rather than simply bending the 620 CBs to stronger lofts (which messed with bounce—Clark wasn’t having that), the team executed a “loft shift.” What’s that, you ask?
It’s a clever little trick: Titleist reassigned iron numbers based on the desired lofts. So Clark’s 620 CB 6-iron became his 7-iron, his 7 became his 8, and so on. The result? The look and feel of the 620 CBs, paired with the launch window and spin numbers of the T100s.
But wait—it gets better. Because a 6-iron head doesn’t weigh the same as a 7-iron, Titleist added lead tape to bring each club up to the proper swing weight. Then, to avoid confusion in the bag, they ground off the original numbers and restamped the new ones. Talk about a custom build.
And here’s the cherry on top: to honor Clark’s late mother, Titleist added pink paint fill to the numbers. It’s a classy, personal touch that makes this already unique set even more meaningful.
Current Setup: T200 Long, 620 CB Mid-to-Short
So what’s in the bag this week at Philadelphia Cricket Club? Clark is rolling with Titleist T200s in his 3-5 irons—great for distance and forgiveness—and his reinvented 620 CBs from 6 through 9.
It’s a story of innovation, personalization, and straight-up creativity—done not in a lab, but on the Titleist Tour truck. And it’s proof that anything is possible when a player knows what they want, and the right team is in place.
