The Numbers Behind Titleist’s Growing GTS Driver Adoption on Tour

*In Partnership with Titleist*

Since Titleist launched the GTS drivers at the Houston Open as part of its tour validation process, there has been a steady stream of players making the switch in search of any advantage they can find off the tee. But tour players don’t change drivers just because one shows up at their door.

With status in majors, world ranking points, the FedEx Cup, and, of course, millions of dollars on the line, there has to be a reason to make the switch, so after the recent Cadillac Championship, we decided to dive into the numbers to see how the GTS driver has helped those who have made the transition.

Players Who Have Switched

The lineup yet to be released to the public includes three new models: GTS2, GTS3 and GTS4. Over 50 players have made the switch to a GTS model as of the Cadillac Championship, including equipment free agents (for clubs) like Patrick Cantlay, Nick Taylor, and Kurt Kitayama, plus Titleist staffers like Jordan Spieth and Justin Thomas.

Once we dive into the numbers, it's easy to understand why these players have made the switch.

What’s especially notable is how quickly players have adopted the new driver during Titleist’s tour seeding process. Often, pros are reluctant to change drivers mid-season unless the performance gains are obvious. Then when equipment free agents start to make the switch too, that says even more.

By The Numbers

Starting with Patrick Cantlay, at the most recent Cadillac Championship, he averaged just over 303 yards off the tee compared to his season average of 299.5 yards with a new GTS4 in the bag. Nick Taylor, who also moved to a GTS4, averaged just over 300 yards at Doral compared to his previous season average of 295 yards.

These jumps might not seem massive, we’re not talking about 30-yard gains here, but at the highest level, even a few extra yards while maintaining control can create a meaningful advantage.

One player who did see a big jump was Kurt Kitayama, who added 17 yards to his 2026 PGA TOUR season average at Doral by averaging over 330 yards off the tee for the event with a GTS3.

What also stands out with the GTS lineup—based on what we know publicly so far—is the added emphasis on adjustability. Compared to the previous GT models, the GTS drivers appear to offer more front-to-back CG tuning, additional rear weighting, and more fitting flexibility overall. For tour players chasing small gains in launch, spin, and dispersion, those added tuning options can make a meaningful difference.

As for Jordan Spieth and Justin Thomas, their stats tell a similar story.

At Doral, Jordan averaged 315 yards compared to his 2026 tour average of just over 308 yards, and Justin gained 9 yards with his 316-yard average with his new GTS2. The other notable part is that, Justin not only gained distance, but also hit over 66% of his fairways compared to his 55% season average.

Early returns don’t tell the whole story, but the trend is already becoming clear. Players aren’t just testing the new GTS drivers, they’re putting them straight into competition and seeing immediate gains. And with an updated tech package and new fitting tools built in, it’s easy to understand why more players are making the switch at a point in the season where every shot matters more.

As for retail, Titleist has already teased a May launch, so it’s fair to expect availability around then. And with more players continuing to make the switch each week, we’ll likely learn even more about the new GTS lineup in the near future. Stay tuned for more updates as they come.
