Collin Morikawa’s year of swaps continues, this time with gear | Tour Report

Welcome to GOLF’s Fully Equipped new weekly Tour equipment report. Each Friday of PGA Tour weeks (plus other times, if news warrants) GOLF equipment editor Jack Hirsh will run you through some of the biggest news surrounding golf clubs on Tour, including changes, tweaks and launches.

Collin Morikawa’s year of changes isn’t restricted to caddies — and it’s taking another turn this week in Napa.

Morikawa has played with five different caddies so far this year and made a number of putter swaps, coming from his trusty TaylorMade TP Soto blade to a Spider Tour V mallet, back to the Soto, to a Logan Olson Tour Matrix 1.0 blade, to a custom TaylorMade proto mallet and back to the Soto. He’s also played around with a Qi35 9-wood instead of a 4-iron.

This week brings more swaps, as Morikawa has bagged a new TaylorMade prototype putter, this time a unique Spider Tour V center-shafted prototype and a new P-DHY utility iron for his 4-iron.

The unique prototype putter, which is a version of TaylorMade’s most forward CG mallet, was working so well in testing for the two-time major winner that he put it into play.

“The center shaft [offset and shaft axis] helped his hand position and release through the stroke,” TaylorMade Tour putter fitter James Holley said. “Spider V also gave him a very efficient face-to-path and closure rate. Compared to his old gamer, the center shafted V was better on left to right and longer putts because the face is delivered more square with less late closure, adding spin and inconsistent ball speeds.”

At the other end of the bag, Morikawa has put in TaylorMade’s P-DHY driving iron, the larger of the two P-series driving irons in TaylorMade’s lineup. The P-DHY features a shallower face height and a wider sole to help increase launch and Morikawa was able to hit his cut shot at 4,500 RPM spin and a 215-yard carry.

If one of the best ball strikers on the PGA Tour is opting to go with a game-improvement style driving iron in place of a traditional 4-iron, it may be worth looking into for your own game.

With both new clubs, Morikawa is four under through two rounds and inside the top-25.

JT goes for GT(3)

Justin Thomas has found his way back onto the U.S. Ryder Cup team after a couple of down years by winning at the RBC Heritage in April and recording eight top-10 finishes.

But according to Titleist tour rep JJ Van Wezenbeeck, Thomas is always searching for ways to further optimize his driver. Despite finishing sixth in strokes gained: total this season, Thomas was 81st off the tee and 148th in total driving.

Thomas opened the season with a Titleist GT2 driver head, the same model he’s played since the Titleist’s GT metals launched on Tour late last summer. While the GT2 has remained constant, he’s tried a few different builds throughout the year, including ones with a prototype Mitsubishi Diamana shaft (which he won with in Hilton Head and had been using recently) and a Fujikura Ventus Black.

But this week, Thomas is going back to Titleist’s lower-spinning “3” head with a new GT3 10.0 driver. Thomas has gone back and forth between Titleist’s “2” and “3” driver heads throughout his career, but most of his wins, including his most recent major at the 2022 PGA Championship, have come with a “3” model.

“Really found an opportunity to go back to a head style that he’s had a lot success with in the ‘3’ model,” Van Wezenbeeck said, adding that the two worked together on drivers in the two weeks since the Tour Championship. “Be able to move to a 10-degree loft from a 9-degree loft and get really good launch-to-spin ratios that’s working really well for Justin.”

Thomas switched out his prototype Diamana shaft for a Diamana ZF 60 TX and also changed his SureFit hosel setting to D-1, lowering the loft back down three-quarters of a degree and moving the sole weight to T1, just toward the toe side.

While he hit just three fairways on Thursday in an opening-round 72, he gained nearly a stroke on the field off the tee and ranked 25th in the category. He again ranked inside the top-25 in SG: off-the-tee during a second-round 70.

Overall, Titleist dominated the driver count this week with 69 players (47 percent) playing a Titleist driver this week, more than double their closest competitor (30).

Titleist GT3 Custom Driver

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.

J.J.’s filling a gap

J.J. Spaun won the U.S. Open with a TaylorMade Qi10 3-wood and 5-wood, but immediately after the victory at the Travelers Championship, the 5-wood was out and matching Qi10 7-wood was back in.

But while the 7-wood was too short to fill his gap between his 3-wood and 4-iron perfectly. And the 5-wood was a bit too long, leading Spaun to switch from week to week depending on course setup.

That gapping issue is what led to Spaun to test and ultimately game a new TaylorMade Qi35 6-wood this week which achieved the perfect 240-yard carry number he was looking for.

Technically, the club is a 7-wood strengthened to 19.5˚, not unlike Scottie Scheffler’s Qi35 7-wood which he refers to as a 5-wood.

But with the new club, Spaun achieves a 240-yard carry with a 157 mph ball speed, 4500 RPM spin and 110-foot apex height, leading to a 46-degree landing angle, giving him a versatile club that can be used off the tee or hold a green on approach.

Through two rounds, Spaun is nine under and in the top-5, five off Ben Griffin’s lead.

Mitchell becomes No. 1 for S-1

Keith Mitchell is breaking in the first set on a worldwide Tour of Mizuno’s new Pro S-1 blades this week at Procore.

Mitchell contributed to the design and shaping of the new iron, which started back in 2022 with the 2019 Honda Classic champion immediately falling in love with the iron’s flatter sole with extra bounce. Mizuno Club Engineer John Freeman said they had been modifying the sole of Mitchell’s Pro 221 blades to match the prototype since then.

Mizuno builder Kyle Hammond built up Mitchell’s first set of S-1s just in the last few weeks and he put them through their paces last week during a session at TPC Sawgrass.

“After about an hour, going through the bag, taking Trackman numbers, he loved them,” Freeman said. “It didn’t take long at all.”

Freeman said Mitchell likes to get his irons to around 100-200 RPMs above the club number (I.e. 7100-7200 for a 7-iron) when he’s hitting shots on the range, because he knows he won’t swing as hard on the course and end up seeing about 300-400 RPMs less.

“Going through the set, the spin numbers and the launch windows for him were dead on,” Freeman said. “My two goals going down there to get these in play were the sole had to perform, and the spin and launch had to be there. He loved the feel; that was not going to be a concern.”

“Keith was definitely instrumental in developing it and loves all those things, but throughout our testing, there were a bunch of other players who loved the same thing, so we’re hoping a lot more of these — whether contracted or non-contracted — in play.”

Mitchell shot 73-68 in the first two rounds and is inside the top 40 heading into the weekend.

3 things you should read

A selection of GOLF articles from the past week that may interest you.

Adam Scott poised to make major gear (and technique) change. Here’s why – Before switching back to his gamer after the opening round, Adam Scott put a conventional-length L.A.B. Golf OZ.1i HS putter in play this week on the DP World Tour. It’s the first time since 2015 he’s used a non-broomstick putter. Scott took 30 putts with the new wand in Round 1 on his way to a 2-under 70, but here how the change came about.

L.A.B. Golf OZ.1i HS Custom Putter

It’s heel-shafted. It’s still L.A.B. Heel-shafted putters have been around forever. No reason they shouldn’t be balanced. OZ.1i HS is the first heel-shafted putter with Lie Angle Balance, giving golfers the traditional look so many love with the ease of use that defines L.A.B. This isn’t just an OZ.1 i with a different neck. Lie Angle Balance demands precision, so we re-engineered the OZ.1 i chassis for a no-compromise heel-shafted design. Our proprietary aluminum riser connects the shaft to the head in a way that maintains Lie Angle Balance and delivers the same forgiveness as the OZ.1i. Golfers who prefer a heel-shafted look no longer have to compromise on performance. And because it’s a L.A.B., you can count on every putter being individually built and balanced. With OZ.1i HS, it’s not where the shaft goes. It’s where the ball goes.
