Adam Scott speaks on new L.A.B. “Mezz.1 Proto” putter at the 2022 WM Phoenix Open



For 2022, Adam Scott is no longer a full Titleist staffer, but he still has a golf ball, glove, and shoe deal.

When he showed up to the 2022 Waste Management Phoenix Open, I was curious to see if he’d have any new gear in the bag due to the new deal, and whether he changed out his 1-of-1 custom Titleist 681.AS irons. As it turns out, Scott has stuck with the new irons, and has 13-of-14 Titleist clubs in the bag.

Make sure to check out his full bag here in the forums.

“I’m not changing much, or need to,” Scott told GolfWRX. “I’m happy with my setup.”

The lone club in the bag that isn’t Titleist, though, is a new L.A.B. Golf Mezz.1 Proto putter that Scott put in play last weekend at the Dubai Desert Classic.

Scott, who prefers to use a long putter in the broomstick style, has experimented with L.A.B.’s original Directed Force putter design in the past, and he used an Armlock version of the original Directed Force head for multiple rounds in Dubai.

This is a new design from L.A.B. that’s a bit sleeker in profile, however.

This week at the 2022 Waste Management Phoenix Open, GolfWRX caught up with Scott to see what’s in his bag, and learn a bit about the new putter.

“I think they’ve refined their design with this new head,” Scott said. “The original head, that Directed Force, maybe was hard for a lot of people to adjust to the size of the head, and this new [Mezz.1 Proto] is smaller, but has the same benefits…I thought the technology in the original was good, but now with the new head design, it feels, looks, does all the things better than the original head for me…I’m looking forward to a week on pure greens to see what happens.”

L.A.B. putters are different than other putters on the market, because they’re engineered to have Lie Angle Balance, which is designed to help reduce torque throughout the stroke.

Scott’s new Mezz.1 Proto putter, in particular, has a raw aluminum finish and has 20 weights in the sole to ensure the head is properly weighted for broomstick and armlock versions.

    I have the standard Mezz. The eventual broomstick release is my next putter, can’t wait for us normal folk to get a chance to own one!!! That head looks killer in the raw metal look. I need to take a cold shower.

    And if you haven’t tried putting broomstick, get on it!! Much easier on the back, and feels totally different than standard putting.

Titleist TSR2, TSR3, TSR4 drivers: Everything you need to know



What you need to know: TSR is the next generation of the Titleist Speed Project that began more than six years ago with the TS series and continued with TSi models in 2020. There are three models in the TSR line, which began tour seeding in June. TSR2 is a high-launch, low-spin “max” driver, balancing speed and stability. Mid-launch, mid-spin TSR3 is the more adjustable option in a tour-preferred shape. TSR4 is the low-launch, low-spin offering now featuring an adjustable weighting system.

Titleist TSR drivers: What’s new, key technology

Multi-Plateau and Speed Ring Variable Face Thickness (VFT) technologies: Two new VFT constructions. For more forgiveness on off-center strikes, TSR2 and TSR4 feature a multi-plateau VFT face that is built inward, layer by layer, to create nearly constant CT across the entire hitting surface. For players who find the center of the face frequently, TSR3 features a Speed Ring face in which Titleist engineers focused on centering the maximum CT/COR relationship into the sweet spot.

Advanced aerodynamics: TSR models feature a new ‘boat tail’ shape with internal weighting to reduce drag.

Player-tuned designs: The look, feel and sound of each of the models were refined as a result of direct feedback from tour players and other “discerning players,” according to Titleist.

Aerospace grade titanium: Premium aerospace grade titanium is again employed in the construction of TSR drivers.

Titleist TSR2, TSR3, TSR4: Additional model details

TSR2: A high-launch, low spin driver designed for the player who makes contact across the face.

  • Improved aerodynamics and a refined, player-preferred shape vs. TSi2
  • Low, forward CG
  • 460cc head
  • Available lofts: RH | 8.0 | 9.0 | 10.0 | 11.0 | LH | 9.0 | 10.0 | 11.0

TSR3: A mid/high launch, low spin player’s driver engineered for playability and precise CG positioning and an improved sweet spot.

  • Reimagined SureFit Adjustable CG Track System for CG positioning
  • Speed Ring VFT Face created using a conical variable face thickness for maximum CT/COR relationship into one central sweet spot.
  • Tour-preferred shape — subtly refined TSi3 look
  • Available lofts: RH | 8.0 | 9.0 | 10.0 | 11.0 (custom) | LH | 9.0 | 8.0, 10.0 (custom)

TSR4: Mid/low launch, low spin, spin-killing driver with adjustability.

  • Built with a multi-plateau VFT face, like TSR2, for consistent speed (and spin) across the face
  • Two adjustable weighting options: a heavier weight in the forward setting maximizes spin reduction, while moving the weight to the back creates more of a “TSR3.5” performance profile
  • 430cc
  • Available lofts: RH | 8.0 | 9.0 | 10.0 | LH | 9.0

What Titleist says

“Titleist TSR represents the deepest, most complete, and most validated understanding of the tee shot ever held within our walls,” said Stephanie Luttrell, Director, Metalwood Development, Titleist. “Every aspect of impact has been considered, constructed and optimized in service of our singular desire to produce more playable distance from every swing. New TSR drivers take everything that made TSi the most played driver on the PGA Tour and pack even more performance into every head. From new face technologies to CG improvements and aerodynamic refinements, TSR helps the golfer unlock more speed.”

Tursky and Knudson tested Titleist’s new TSR drivers: Here’s what happened



Titleist’s new line of TSR drivers and fairway woods – which replace the former TSi series – launched on the PGA Tour at the 2022 Travelers Championship at TPC River Highlands in Cromwell, Connecticut.

The previous iteration of TSi drivers remained hugely popular in the marketplace, and on the PGA Tour, throughout its life cycle. As Titleist reports, the TSi3 driver model was the most played driver over the 47-event PGA Tour 2021-22 season, with 19 percent usage. Titleist’s TSi drivers were noteworthy for the simplicity and effectiveness of adjustability, and for their fast 425 ATI Aerospace Titanium face inserts that produced higher speeds than previous drivers.

Although the TSR had big shoes to fill, Tour players switched in droves starting at the Travelers Championship. In the first week, 18 players switched into a new TSR driver, and 13 players switched into a new TSR fairway wood.

The momentum has only continued since then. Over the last several months, four players have won on the PGA Tour using a Titleist TSR3 driver model: J.T. Poston at the 2022 John Deere Classic, Cam Smith at the 2022 Open Championship, Joohyung “Tom” Kim at the 2022 Wyndham Championship, and Will Zalatoris at the 2022 FedEx St. Jude Championship.

GolfWRX spoke with Poston and Lanto Griffin to get their initial feedback on the TSR drivers and fairways, and we caught up with Zalatoris at the Scottish Open to hear his thoughts.

A post shared by PGA TOUR (@pgatour)

The general consensus seemed to be that Tour players liked the new sound and feel, and they were finding distance gains compared to the previous TSi lineup. They also spoke highly of the increased launch in the fairway woods, without adding too much spin, and they liked the new full-faced grooves.

OK, so the pros are loving the new TSR drivers and fairways, and they’ve been switching into the new models quite seamlessly. Got it.

Now it’s our turn to try them out.

Recently, before the official retail launch of the TSR products, GolfWRX’s Brian Knudson and Andrew Tursky visited the Titleist Performance Institute (TPI) in Oceanside, California to get a full driver and fairway wood fitting, and to test out the new TSR products against their current gamers.

Here’s what happened for each of them:

Brian Knudson’s TSR fitting

Handicap: 9.9

Driver Swing Speed: 101 – 104 mph

Typical Driver Miss: Hook Left. Ball starts left of target and hooks with low trajectory

Previous Gamer Driver: Titleist TSi3 (9.0 degrees, set to C4 w/ Miyazaki Kusala White 61x, 45 inches)

New TSR Driver Model:  TSR 2 (10 degrees, set to B1, Project X HZRDUS Black 4th Gen 60g 6.5, 44.5 inches)

Knudson’s Thoughts on the TSR Drivers: The TSR drivers really look and feel great, and the TSR2 gives you confidence that you can get away with a bad swing. I loved that on a less-than-perfect swing I saw really good ball speed and dispersion numbers. The TSR2 offered me better consistency on spin, ball speed, and launch compared to my TSi3 across all shots.

Previous Gamer Fairway Wood: TaylorMade SIM2 Max 3 wood (15 degrees, w/ Fujikura Speeder NX 70x, 42.5 inches)

New TSR Fairway Model: Titleist TSR2 (15 and 18 degrees, w/ Project X HZRDUS Black 4th Gen 70g and 80g 6.0, 42.5 and 42 inches)

Knudson’s Thoughts on the TSR Fairways: The biggest thing I noticed immediately was how easy the TSR woods are to launch. I don’t hit a high ball, and these easily got the ball in the air and went a long way. The 15-degree was set a little lower with the SureFit hosel, and I was still able to launch it off the deck with no issues. The 18-degree fit my gapping better than the 21-degree and still hit the launch window that I was looking for.

Andrew Tursky’s TSR fitting

Handicap: 2

Driver Swing Speed: 110-115 mph

Typical Driver Miss: A pull hook that starts left and goes left, and spin tends gets a little too high. Low-spin, fade-biased drivers are beneficial.

Previous Gamer Driver: Callaway Rogue ST Triple Diamond LS (10.5 degrees, Mitsubishi Tensei AV White 65X shaft, 45.5 inches)

New TSR Driver Model: Titleist TSR3 (10 degrees, Mitsubishi Tensei 1K Black 75X shaft, 44.75 inches, +2 grams SureFit Weight, Toe 2 SureFit CG Setting, C1 hosel setting)

Tursky’s Thoughts on the TSR Drivers: “Within my first few swings with the TSR3, my immediate takeaway was that the face felt soft and springy, and the sound was a bit more muted than TSi3. I preferred the profile and performance of the TSR3 vs. the TSR2, because the TSR3 was offering a bit lower spin and launch numbers for me, and I prefer the more compact shape.

My fitter and I decided to go slightly shorter on the length for control, slightly heavier on the head weight, and we put the SureFit CG weight in the most fade-biased position; this helped me feel like I could really release the club face without losing the ball too far left. We also went to a midsize grip instead of standard with two wraps. Grip fitting is underrated, in my opinion, so in your next fitting, make sure to mention you want to try some different grip sizes.

In the end, I gained both distance – despite the 0.75-inch decrease in length – and accuracy compared to my previous gamer. Looks wise, the TSR definitely has that classic glossy black ‘Titleist’ look that’s appealing in its simplicity. Longtime Titleist users will love the clean profile from address, and the modern look of the soles. This is definitely an upgrade from the TSi drivers, which were all-around great performers across the board, and probably the best Titleist drivers of the last decade. They changed just enough with the TSR to make improvements, without messing up a great thing. I think that was the goal, and they achieved it.”

Previous Gamer Fairway Wood: TaylorMade AeroBurner TP (12 degrees, Graphite Design Tour AD-DI 7X)

New TSR Fairway Model: Titleist TSR3 (15 degrees, Mitsubishi Tensei 1K Black 75X shaft, -0.25 inches, +6 grams SureFit Weight, Toe 1 SureFit CG setting, C1 hosel setting)

Tursky’s Thoughts on the TSR Fairways: “I wasn’t really in the market to replace my longtime AeroBurner Mini driver, because it’s been so reliable over the years. I mostly use it off the tee, but occasionally I’ll hit it from the turf when the time is right. The new TSR2+ blew the Mini Driver out of the water in terms of distance and accuracy, but it was actually going a bit too far and the profile was a touch larger than I wanted when hitting off the deck. Those who want something slightly larger and want to maximize distance/forgiveness will love this new option.

The TSR3 was right in my wheelhouse of looks, and it was offering a really easy launch off the deck. Somehow, although it’s 3 degrees weaker and an inch shorter, the TSR3 fairway was matching my max distances with the Mini Driver, even off the tee, and it offered way higher launch and forgiveness from the turf.

Compared to the previous TSi fairways, I already know everyone will like the full face grooves. And I do, too. They really help frame the ball properly and make aligning to the target a bit easier for me.”

Tech Talk: The new TSR designs

During GolfWRX’s visit to TPI, GolfWRX’s Andrew Tursky sat down with Stephanie Luttrell, the Director of Metalwood Development for Titleist, to learn about the new technology.

Here are the most prominent takeaways for the new TSR driver designs:

  • There are 3 models: TSR2, TSR3 and TSR4, each with distinct designs (the TSR2 is built for speed and forgiveness, the TSR3 is for speed and distance, with a SureFit Adjustable CG track, and the TSR4 is for low spin, also with adjustable weighting in the sole)
  • A new “boat tail” head shape is designed to improve aerodynamics for faster swing speeds
  • Two different face structures are used within the lineup: the TSR2 and TSR4 use a “multi-plateau variable face thickness (VFT)” that’s designed for more forgiveness and constant CT (characteristic of time) across the face, while the TSR3 uses a new “Speed Ring” that focuses on centering max CT into the sweet spot to increase speed on center strikes
  • The TSR drivers continue to use aerospace grade titanium face inserts, like the previous TSi drivers, and they have compatible SureFit hosels for lie and loft adjustments

And here are the most notable takeaways for the new TSR fairway woods:

  • There are 3 models: TSR2, TSR3 and TSR2+ (the TSR2 has Titleist’s lowest ever CG for a steel construction and is made for high launch/mid spin, the TSR3 has a lower and deeper CG than the TSi3 and comes with an SureFit Adjustable CG Track on the sole; it’s made for mid/high launch and low spin, and the new TSR2+ has a larger profile, taller face, and the deepest CG to maximize distance and forgiveness off the tee)
  • An “Open Hosel Construction” removes unwanted weight from the high-heel section of the head, which helps moves weight lower, deeper and toward the face center
  • Zalatoris spoke on the new TSR2+ fairway: “This is an absolute rocket. I love this thing. It’s the best 3-wood I’ve ever had. It’s pretty cool to be able to have something besides driver that I can hit off the tee and basically hit it as far as I want. And then if I need to hit high and soft into greens, I can do that as well.”

Titleist introduces new TSR metalwoods



Titleist has today introduced its all-new lineup of TSR metalwoods, featuring three distinct models: TSR2, TSR2+, and TSR3.

The new TSR fairway metals exemplify the newest advancements in metalwood technology and offer options for all golfers looking to gain an advantage off the tee and off the deckCombined with its tour-inspired shaping and powerful sound and feel, the optimized performance of TSR fairways sets a new standard for the Titleist Speed Project.” – Stephanie Luttrell, Director, Metalwood Development, Titleist

Open Hosel Construction

One of the key new features of TSR2, TSR2+ and TSR3 fairways is the Open Hosel Construction.

Titleist engineers were able to remove excess weight found high and towards the heel of the clubhead, which allowed them to reposition weight in design to make improvements to essential areas of performance.

In the TSR3 fairways, engineers utilized the Open Hosel Construction to shift the CG deeper and lower while simultaneously moving it closer to the center of the face. This change aims to offer even more forgiveness with a higher launch.

Low Face Centered CG

The TSR2 features Titleist’s lowest ever CG for an all-steel construction, while the TSR2+ boasts the deepest CG of any Titleist fairway metal. TSR3 has an even deeper and lower CG than its predecessor. The CG location is engineered for the specific needs of each fairway model, with all designed to provide maximum levels of forgiveness, high launch, and speed.

Player-Tuned Performance

Another commonality between TSR2, TSR2+, and TSR3 is the player-tuned performance. Implementing key feedback from tour professionals, every detail contained in the look, feel, and sound of TSR fairways has been scrutinized to deliver a metal wood that is designed to instill confidence in every player.


“High, far, and forgiving, the TSR2 fairway features maximum forgiveness and the lowest CG of the TSR fairway metal line, resulting in fast speeds and a high ball flight.”

Key features:
  • TSR2 fairways feature the lowest CG ever for an all-steel construction in design to create speed and launch without excessive spin.
  • New Open Hosel Construction created space for sizable improvements to key areas of performance by removing unwanted weight high and towards the heel.
  • Engineered to sound and feel powerful, giving players a lively response on every strike.
  • Adjustable swing weight, fixed CG location.
  • High launch, mid-spin
  • Available lofts: RH: 15.0, 16.5, 18.0, and 21.0 degrees; LH: 15.0, 16.5, and 18.0 degrees


“Inspired by the wants and needs of some of the world’s top tour professionals, the TSR2+ fairway is a new addition to the TS fairway family, designed to be a long, forgiving, and tee-biased 3 wood that does not sacrifice playability off the deck.”

Key features:
  • Built for the tee, TSR2+ has a larger profile, taller face and more forgiveness than TSR2
  • Featuring the deepest CG location of any Titleist fairway metal, TSR2+ is designed to offer maximum forgiveness and a straight, pure ball flight.
  • TSR2+ was asked for by Tour Pros but is built to benefit all golfers looking for a long and straight option off the tee that is still extremely playable off the deck.
  • Adjustable swing weight, fixed CG location.
  • Mid/high launch, mid-spin
  • Available lofts: RH: 13.0 degrees; LH: 13.0 degrees


“For players seeking precision-tuned performance, featuring a lower, deeper CG and a new-and-improved 5-position SureFit Adjustable CG Track System.”

Key features:

  • The ultimate fairway metal when it comes to adjustability is designed with a new, easy-to-adjust 5-position SureFit Adjustable CG Track System to fine tune performance.
  • Featuring the same Open Hosel Construction as TSR2 fairways, the TSR3’s CG has been positioned deeper, slightly lower, and closer to face center to provide easy, high launch with plenty of forgiveness.
  • The look, sound, and feel of TSR3 is designed to encourage players to hit it square and long with total precision.
  • Adjustable swing weight and CG location.
  • Mid/high launch, low-spin
  • Available lofts: RH: 13.5, 15.0, 16.5, and 18.0 degrees; LH: 15.0 and 16.5 degrees

The Titleist TSR fairway metalwoods are available in golf shops worldwide beginning September 23 and cost $349 per club ($549 Premium)
