His total distance efficiency (total distance divided by club head speed) was 2.62, which would be 63rd on Tour and up from his season average of 2.572.
What does this all mean?
We’ve known this year’s drivers were fast, but now we can see evidence of it.
The fact that Scheffler wasn’t swinging as fast in Round 1, likely a little gun-shy in his first round using the new big stick, yet still increasing his average ball speed by 2.6 mph, is a massive gain. If Scottie Scheffler is picking up 2.6 mph of ball speed, that can’t be good for the rest of the field.
It will be interesting to track as he logs more rounds with the new driver and gets more comfortable with it. With that comfort will probably come more fairways as well.
But there’s a reason Scheffler seemed pleased with his results off the tee with the new driver on Thursday. He specifically called out the spin retention of the new driver on Thursday, which owes to the new, tighter roll radius of the Qi4D face.
“I feel like what we have seen is more consistent spin numbers,” he said. “So that will help it be a little bit more accurate off the tee. Directionally, I struggled a little bit with it at the start of the year, but I got to what I thought was a really good spot last week, and I liked what I saw today.”

Drivers are still unsettled
Scheffler wasn’t the only big name to make a driver switch this week.
Cameron Young switched out of his Titleist GT2 driver for an 11.0-degree GT3 with the same Mitsubishi Tensei 1K Pro Orange 70 TX shaft he had in his GT2. The higher loft of the lower-spinning GT3 head helped him further optimize his numbers as switching to the Pro V1x Double Dot Prototype last summer.
The prototype Double Dot flies lower than his previous Pro V1x, so Young worked with the Titleist team to see what he needed to do to optimize carry with his driver, Titleist Director of Player Promotion J.J. Van Wezenbeeck said.
Working together with Titleist’s Director of Tour Research & Validation, Fordie Pitts, the team determined Young needed a touch more launch. The 11-degree GT3 (lofted down .75˚ in the D1 setting) succeeded in getting launch up from 9 degrees to 11 while only going from 2400 to 2500 rpm spin.

GT3 – Speed-Tuned Distance & Control
GT3 offers Titleist’s boldest combination of power and personalization. With a speed-tuned design that allows you to precisely match performance to your most frequent contact location, you can make your biggest drives even bigger while taking total control over flight and shaping.
For players with a relatively consistent impact location, GT3 offers a precisely adjustable CG Track to max out distance and directional control.
Seamless Thermoform Crown
A reimagined ultra-lightweight design, born from a new Proprietary Matrix Polymer. The tunable acoustic properties of this unique composite allow Titleist engineers to realize new material gains while maintaining our signature sound and feel. All wrapped in a clean look that inspires total confidence.
Split Mass Construction
A breakthrough in internal weighting unlocks longer drives and enhanced directional control in GT3. The Adjustable CG Track now sits closer to the face for more dynamic CG control, while additional discretionary mass is pushed to the back of the club to maintain optimal stability through impact.
Advanced Aerodynamics
GT3 features a new raised tail contour that represents a dramatic shift in driver aerodynamics. Previously impossible to execute due to design constraints, this advanced shaping results in a driver that swings faster while still providing optimal CG control.

The reason for going to a higher lofted, but more forward CG head was so they could increase the launch without increasing spin. Young led the field and gained 2.277 strokes off the tee in Round 1.
Lucas Glover also added a new Qi4D driver, which is at least his third driver change of the year. That’s similar to Wyndham Clark, who is also most recently in a Qi4D and has played four different drivers this year. And Harry Hall, who earlier this season played a Qi4D LS before switching to Titleist driver, is now playing the core model this week.
Meanwhile, Denny McCarthy added a G440K.
Normally, some of these trivial week-to-week changes would go down in Odds and Ends, but it seems like more players, especially gear free agents, are swapping drivers this season. That’s likely a testament to how good the offerings are; players have taken notice.
“What I’m seeing… heads are a close battle this year,” Fujikura Tour Rep Marshall Thompson told GOLF this week. “It’s very competitive in terms of club speed, dispersion, center-face contact, start direction. There’s not one clear-cut winner from what I’ve seen.
“Even on the Tour side of it, these non-contract guys that I continue to work with on a weekly basis, they still have four or five headcovers in the bag and they’re still trying different options, and we’re already to the Florida Swing.”
