Golf Data Lab Statement by Graeme Leslie GolfDataLab Founder

"It's up to the golfer if he or she wants to perform better. Seriously, it's that simple."

If you want to improve, it's down to you. As soon as you get called to the first tee, you're on your own. The work has been done. Your biomechanist and your swing, short game and putting coaches have given you the technical fundamentals and your psychologist/mentor/performance coach/data and stats analyst have helped you to manage your mind, yourself and your expectations. You have a strategy and a plan. Your movement has been improved through kinesiology and your strength and conditioning and nutritional experts have prepared you to be in the optimum physical condition for this moment.

"That's a lot of people but ultimately, it's up/down to you as to how you perform and what you score."
And there will be ups and there will be downs. This is a game of never-perfect after all. It's also a game of huge variables, you will be 100% getting up and down one day, 0% the next. Most specialists in golf help with your practise and preparation. There are less of us who are dedicated to measuring and reflecting. Yet we need data, facts and stats in order to help to shape our practise and focus our minds.

As a European Tour winner (including of the "fifth major") client of ours says,

"if you're not assessing, you're guessing".

At Golf Data Lab we believe that the "Circle of Golf" interlinks all three functions and that they are interdependent. In order to perform better and find greater consistency, we will have practised hard, practised smart and prepared well. After performing, we reflect and learn what we did right, wrong or indifferent and this shapes the composition of our practise, how we prepare and what we tweak or change for the next time. 


DeChambeau’s “outside-the-box” approach to the game.

DeChambeau, recorded rounds of 69, 68, 70 and 67 to capture a six stroke victory at the 120th U.S. Open held at the legendary Winged Foot Golf Club in Mamaroneck, New York.

DeChambeau was the only player to finish the tournament under par. This was his eighth win and first major title since he joined the PGA TOUR in 2017.

He ranked 1st in Eagles, T-4th in Birdies, 1st in Strokes Gained Tee to Green (17.918), 1st in Strokes Gained Approach to the Green (7.608), 2nd in Strokes Gained Off the Tee (5.331), and 1st in Strokes Gained Total (22.273). He also ranked 3rd in Scrambling (65.38%), 3rd in Putting (+2.99) and T-5th for Greens in Regulation (63.89%).

This U.S. Open victory was a major validation of DeChambeau’s “outside-the-box” approach to the game.

“One hundred percent, no doubt,” DeChambeau said. “For me, it’s about the journey of can I execute every shot more repeatable than everybody else. I was able to do that this week. That’s why I won by six.”

This victory earned him a paycheck for $2.25 million dollars and 600 FedEx Cup Points. He is now ranked 1st on the FedEx Cup Points List and 9th in the Official World Golf Rankings.


Bryson DeChambeau wins the 120th US Open superior. 

The "muscle man" hit only 23 fairways, but he still distanced the entire competition by six or more strokes ...

The Pitch from Caddie CaddyShack " I am the man for your bag" 
Where’s the flag?” DeChambeau asked his caddie Tim Tucker as they stood on the tee at the 444-yard, par-4 14th hole. At this point DeChambeau, who has always sought every piece of information available, was already three up on a faltering Wolff.
“Twelve on and four off the left,” Tucker said.
With that, DeChambeau swung from the heels and ripped a 296-yard drive – into the wind.
Did it hit the fairway? Oddly enough, DeChambeau made that question a moot point. He hit six of 14 fairways Sunday and 23 of 56 for the week, but thrived, anyway. That flew in the face of the conventional wisdom that there was absolutely no way to play Winged Foot from the rough...
We saw it all DeChambeau's scientifical approach did work at Winged Foot.

"DJ" 's FedexCup win reveals his PGA tour domination since 2008 and reminds us of the 2011 "TAP" Putting breakthrough research findings by "SB".

Speaking from the DucksInn/Aberlady/EastLothian/Scotland, by Stephane Barras 

Should we say a "Tap" or a "Tap IN"? What is its distance and how should we execute it?

These are many questions that were unanswered before 2011. Since 2012 and the International research publication of "Better Understanding Putting Definition Perception and Goals"  every thing is clearer today due to the so called the Barras SPD (Standard Putting Definition) .

During my 6 months quest/research around the world as far as Australia to better understand putting, I had the privilege to and or follow/coach/caddie/interview some of the best players in the World. At that time Dustin Johnston was the World no.9 and I attended one of his media interview.

Quote from Dustin Johnston after his 66 second round at the 2011 Austrailian Open : "Today I have missed a few short putts. Most birdies I made were "TAP-IN" or from 3 to 4 feet"  

As a result and after gathering all the data and information needed. > We now should say "TAP" (from 0 to 2 feet - Zone1) > You can find all details described in my book "LaDifference" 5th (French) edition page on 164 or on (English).

Well done DJ!  "TAP" seulement "IN" ... by "SB"

Best "SwingScore" to win the FedEx BMW Championship or?

Print Friendly, PDF & Email

We will surely remember the two monster putts that went in at Olympic Fields as the way to win golf tournaments  > One from Dustin on 18th from 33 feet to force the Playoff and the other one from Rham 66 feet to win it.... not forgeting John's "Drop" brain down on Saturday... >

What we see @CaddiePlayer is that both players did not reach our long putt ratio target 10% In from Zone4 and that once again the best #SwingScore wins.

Any Comments? 


Quote from Justin Ray @15thClub

An incredible final round at the BMW Championship concluded with Jon Rahm making a 66-foot putt on the first playoff hole to defeat Dustin Johnson. It was the longest putt Rahm has made on the PGA Tour all season long and just two feet away from being his career-long make. Rahm now has eleven official worldwide wins since 2017, tied with Justin Thomas for most in that span.
