Austin Smotherman was teammates with Bryson DeChambeau at SMU before turning professional in 2016.

After spells on the PGA Tour Latinamerica and Korn Ferry Tour, Smotherman earned his PGA Tour card for the 2021/22 season, before dropping back down to the Korn Ferry Tour in 2025.

Undeterred, Blixt made it to The Masters in 2014, and, helped by Williamson, he did brilliantly, finishing T2 behind Bubba Watson.

The Swede performed admirably at the 2015 edition, too, where Williamson was still on his bag as he finished T28.

Eventually, the pair parted ways, with Williamson going on to caddie for the likes of Bud Cauley and Sam Ryder before linking up long-term with Doc Redman.

By 2022, Smotherman’s caddie was Austin Gaugert, but eventually, he began working with Williamson, and they haven’t looked back.

After Smotherman’s brilliant Korn Ferry Tour season in 2025, he acknowledged Williamson’s role at the end of the year, writing on Instagram: “Special shoutout to my coach @cmccormickgolf, @altusperformance, my caddy @zakwilliamson, and Richard Zulick at @noblesportsgroup – y’all are the real MVPs.”

With Williamson’s help, Smoetherman has carried that form into 2026, including sitting proudly at the top of the leaderboard at the halfway point of the 2026 Cognizant Classic, where, with a two-shot advantage, he was eyeing his maiden PGA Tour title.
