Jordan Spieth switched from the 2025 Titleist Pro V1x to the 2026 Pro V1x Left Dash during Cadillac Championship week at Trump National Doral, pairing the ball change with a new driver and 3-wood as part of a broader equipment reset designed to lower spin without losing height. He opened the tournament with a 7-under 65.

The move was rare for Spieth, who told the PGA TOUR he had “put a new driver, 3-wood and golf ball in.” But it was the ball that carried the most weight. As GolfDigest reported, the change had been building for roughly a year and a half, with iron shots behaving in ways that no longer matched what Spieth expected from his swing. 

“A ball change would be extremely rare,”

What Changed at Doral

The full equipment reset involved moving from a TSR2 driver to a GTS2 driver, a TSR3 3-wood to a GTS2 model, and the Pro V1x to the Pro V1x Left Dash. Spieth hit 190 balls on the range Tuesday before the first round, the most of any player in the field that day.

GolfDigest described that range session as “a guy validating a decision he had already made.” The driver and 3-wood were part of the picture, but the ball was the centerpiece. Spieth said the 3-wood was still on trial: “I’m not sure if that’s a winner yet. It’s kind of a trial run.”

Why He Went Looking

The trigger was iron shots that kept coming off with too much spin and finishing short of the target. Spieth said the problem had surfaced repeatedly over roughly 18 months but was hard to pin down at first.

“I just thought it was a driving range thing and I’ve been taking my monitor onto the golf course and trying to see.”

The breakthrough came two weeks before Doral, during a practice round at Harbour Town. Using a launch monitor on the course, Spieth watched what he considered a perfect iron shot come up short, then saw the pattern repeat. That was the sample size he needed.

“Then I had, I don’t know, maybe a dozen shots I could tell you in the last year or so that came off just odd for an iron, spinny, ended up short. It was enough of a sample size to say let me explore other options.”

Spieth had long played the highest-spinning ball in the Titleist lineup because he believed he needed the extra spin on long irons. But his speed and delivery had shifted enough that his spin rates were no longer low, and in some cases were actively working against him.

“I’ve always played the highest spin ball because I thought I needed it in the long irons. Now … my spin rates have been fine if not too high. So, it’s actually kind of nice to be able to drop it down a little bit.”

What the Left Dash Gave Him

Testing the Pro V1x Left Dash produced a drop in spin between 300 and 500 rpm depending on the club, according to GolfDigest. GOLF.com’s analysis put the figure at roughly 500 rpm less with irons while maintaining the same flight window.

Spieth framed the result simply: “It’s just a lower spinning ball with the same height.”

He did change balls once before, in Palm Beach during the 2025 season, but that adjustment stayed within a similar spin profile. The Left Dash was a bigger departure.

“I did a ball change in Palm Beach last year, but I did it to a ball that was a little more similar,” Spieth said. “This is a little bit bigger jump.”

After enough testing, Spieth was satisfied the switch was the right call. “I hit enough shots to feel confident that it was better for me than what I was playing,” he said.

A Fitting Choice That Aged Out

GOLF.com connected Spieth’s move to a wider principle in elite fitting: ball selection should evolve with the player, not stay locked in place because it worked three years ago. The piece described Titleist’s fitting philosophy as “green back to the tee,” starting with short game and wedge performance before working outward to irons and driver.

In Spieth’s case, the swing changes and delivery adjustments he had made over recent seasons shifted his spin numbers enough that the ball he had trusted for years was no longer the best match. His iron delivery had become more stable and penetrating, which meant the extra spin that once helped him hold long-iron shots was now costing him carry distance on mid-iron approaches.

The timing aligned with a steadier run of form in 2026. Entering the Cadillac Championship, Spieth had climbed back to No. 50 in the Official World Golf Ranking after posting four top-15 finishes in 10 starts and missing just one cut, according to Golfweek. His strokes-gained approach the green sat at 0.294 and putting at 0.423 heading into the week, per PGA TOUR data.

The equipment reset amounted to optimization inside an already improving season for a 32-year-old, 13-time PGA TOUR winner who noticed a problem, gathered data and made a change he had been reluctant to make for years.
