The key to putter fitting? Know your roll

This is the second installment of a four-part series from Modern Golf on putter fitting and the Quintic System.

Find a busy practice putting green, and it’s almost guaranteed that you’ll see at least a few golfers obsessing over the motion of their putting stroke. They’re usually the ones who are using some kind of training aid to help them groove their stroke in a certain way.

For many golfer, it can be time well spent. But what they might not know is that the way their putter moves is only half the equation to good putting. Did you know that two putts with the same clubhead speed can travel significantly different distances? Did you also know that most golfers actually do a good job of consistently swinging the putter through at their desired speed? So why do so many golfers have problems with their distance control? The other half of the equation is controlling what is called their ball roll.

How do golfers control how their ball roll? How should the ball be rolling? It is a very difficult question to answer without using high-speed cameras and motion capturing. Using a system called Quintic, we provide golfers the knowledge and data they need to putt their best. Understanding this data will improve your game.

The image below shows what an ideal 8-foot putt looks like on our Quintic System.

Forward Rotation

As you can see, the ball instantly started to rotate forward off the putter face. A ball that has negative initial ball roll, or “backspin,” will lose speed and can deflect offline. Having the ball rotate forward off the face will give players better distance control with their putts because the ball will lose less energy and stay on its intended line longer. This will aid the ball in rolling over debris and other imperfections on the green such as ball marks, spike marks, etc.

Having anywhere from +25 rpm to +50 rpm initial ball roll is ideal. Any higher and the ball will roll out longer because it will be carrying more momentum. This can make downhill 5 footers scarier than they already are. With an rpm under +20 rpm, the ball doesn’t carry as much momentum to the hole.

Launch

The ball was launched at about 1.75 degrees. An ideal launch angle on most greens is between 0.75 degrees and 2 degrees. Much like a driver, controlling launch has a big influence on how far the ball will travel. That is because on the green, a ball will sit in a small depression as a result of gravity. The ball needs to be launched out of this depression — and not too high or too low. Optimal launch should change depending on the blade length of the grass and the type of putting surface. On lush greens with a longer blade length, the ball will sit in a deeper depression. On firm greens with a short blade length, the ball will not sit in such a deep depression, and for that reason not as much launch is required.

The image below shows what happens to a putt that has a launch angle that is too high.

Zero Skid

Minimal skid is ideal. On a well struck putt, there should be less than 10 percent skid for the total distance the ball travels. So on an 8-foot putt, ideally there should be less than 10 inches of skid (see first image). Once “zero skid” occurs, the ball starts rolling on top of the grass smoothly. When there is too much skid, the result is a loss of distance and ball speed. Every time the ball bounces and strikes the putting surface it loses energy — energy that has been factored into your putt for speed and distance. These putts tend to come up short and offline, and this often happens with long putts or lag putts.

Below are images of a “dew board.” The board simulates putting through an early morning dew where it is easy to see launch and skid. There are two visible lines on the board. The putt that has a flat and consistent line has optimal launch and minimal skid. The putt that looks dotted or chattered has launched too high, increasing the zero skid parameter. The dots are where the ball has struck the putting surface and continues to hop until it reaches zero skid.

Every putt, at some point, reaches zero skid. Reducing the amount of time it takes for the ball to reach zero skid will ensure that the ball will lose minimal energy and carry more momentum to the hole.

Impact Ratio

This refers to how efficiently clubhead speed is converted into ball speed. For all of those Trackman users out there, this is the same as smash factor. It is a simple calculation: ball speed divided by clubhead speed. Controlling the speed that the ball comes off the face is crucial. This is achieved when the center mass of the club head makes contact with the center mass of the golf ball. Any off-center strike results in a loss of ball speed and face deflection, causing the ball to roll offline with less speed.

We’ve all hit full shots that weren’t solidly struck and they come up short of our target. The exact same thing happens when we don’t hit a putt solid, but it’s much harder to feel the mishit because the clubhead speed is much slower through impact with a putter. This is where most golfers struggle.

The face of the putter also needs to be square to the path of the club. Otherwise, you’ll see a glancing blow that also reduces ball speed. The type of putter a player uses also has an effect on ball speed. Putters with softer inserts reduce ball speed because of reduced energy transfer from the club head to the ball. To illustrate where you strike the ball on the clubface, spray the face of the putter with Doctor Scholl’s foot spray. It will show you where the ball is making contact with the face, and has minimal effect on ball speed and friction.

Certainly there are other parameters to consider, but this article should provide golfers with a general concept that they may not have considered in the past. Without knowing what the ball is doing, it is very difficult to teach someone proper putting mechanics. Players who have a better understanding of how the ball is rolling have a better chance of improving their game on the greens. Therefore, go get fit for a putter and KNOW YOUR ROLL.

Vincenzi’s LIV Golf Singapore betting preview: Course specialist ready to thrive once again

Published

6 days ago

Apr 30, 2024

Matt Vincenzi

After another strong showing in Australia, LIV Golf will head to Sentosa Golf Club in Singapore looking to build off of what was undoubtedly their best event to date.

Sentosa Golf Club sits on the southern tip of Singapore and is one of the most beautiful courses in the world. The course is more than just incredible scenically; it was also rated 55th in Golf Digest’s top-100 courses in 2022-2023 and has been consistently regarded as one of the best courses in Asia. Prior to being part of the LIV rotation, the course hosted the Singapore Open every year since 2005.

Sentosa Golf Club is a par 71 measuring 7,406 yards. The course will require precise ball striking and some length off the tee. It’s possible to go low due to the pristine conditions, but there are also plenty of hazards and difficult spots on the course that can bring double bogey into play in a hurry. The Bermudagrass greens are perfectly manicured, and the course has spent millions on the sub-air system to keep the greens rolling fast. I spoke to Asian Tour player, Travis Smyth, who described the greens as “the best [he’s] ever played.”

Davis Love III, who competed in a Singapore Open in 2019, also gushed over the condition of the golf course.

“I love the greens. They are fabulous,” the 21-time PGA Tour winner said.

Love III also spoke about other aspects of the golf course.

“The greens are great; the fairways are perfect. It is a wonderful course, and it’s tricky off the tee.”

“It’s a long golf course, and you get some long iron shots. It takes somebody hitting it great to hit every green even though they are big.”

As Love III said, the course can be difficult off the tee due to the length of the course and the trouble looming around every corner. It will take a terrific ball striking week to win at Sentosa Golf Club.

In his pre-tournament press conference last season, Phil Mickelson echoed many of the same sentiments.

“To play Sentosa effectively, you’re going to have a lot of shots from 160 to 210, a lot of full 6-, 7-, 8-iron shots, and you need to hit those really well and you need to drive the ball well.”

Golfers who excel from tee to green and can dial in their longer irons will have a massive advantage this week.

LIV Golf Singapore Picks

Sergio Garcia +3000 (DraftKings)

Sergio Garcia is no stranger to Sentosa Golf Club. The Spaniard won the Singapore Open in 2018 by five strokes and lost in a playoff at LIV Singapore last year to scorching hot Talor Gooch. Looking at the course setup, it’s no surprise that a player like Sergio has played incredible golf here. He’s long off the tee and is one of the better long iron players in the world when he’s in form. Garcia is also statistically a much better putter on Bermudagrass than he is on other putting surfaces. He’s putt extremely well on Sentosa’s incredibly pure green complexes.

This season, Garcia has two runner-up finishes, both of them being playoff losses. Both El Camaleon and Doral are courses he’s had success at in his career. The Spaniard is a player who plays well at his tracks, and Sentosa is one of them. I believe Sergio will get himself in the mix this week. Hopefully the third time is a charm in Singapore.

Paul Casey +3300 (FanDuel)

Paul Casey is in the midst of one of his best seasons in the five years or so. The results recently have been up and down, but he’s shown that when he’s on a golf course that suits his game, he’s amongst the contenders.

This season, Casey has finishes of T5 (LIV Las Vegas), T2 (LIV Hong Kong), and a 6th at the Singapore Classic on the DP World Tour. At his best, the Englishman is one of the best long iron players in the world, which makes him a strong fit for Sentosa. Despite being in poor form last season, he was able to fire a Sunday 63, which shows he can low here at the course.

It’s been three years since Casey has won a tournament (Omega Dubai Desert Classic in 2021), but he’s been one of the top players on LIV this season and I think he can get it done at some point this season.

Mito Pereira +5000 (Bet365)

Since Mito Pereira’s unfortunate demise at the 2022 PGA Championship, he’s been extremely inconsistent. However, over the past few months, the Chilean has played well on the International Series as well as his most recent LIV start. Mito finished 8th at LIV Adelaide, which was his best LIV finish this season.

Last year, Pereira finished 5th at LIV Singapore, shooting fantastic rounds of 67-66-66. It makes sense why Mito would like Sentosa, as preeminent ball strikers tend to rise to the challenge of the golf course. He’s a great long iron player who is long and straight off the tee.

Mito has some experience playing in Asia and is one of the most talented players on LIV who’s yet to get in the winner’s circle. I have questions about whether or not he can come through once in contention, but if he gets there, I’m happy to roll the dice.

Andy Ogletree +15000 (DraftKings)

Andy Ogletree is a player I expected to have a strong 2024 but struggled early in his first full season on LIV. After failing to crack the top-25 in any LIV event this year, the former U.S. Amateur champion finally figured things out, finished in a tie for 3rd at LIV Adelaide.

Ogletree should be incredible comfortable playing in Singapore. He won the International Series Qatar last year and finished T3 at the International Series Singapore. The 26-year-old was arguably the best player on the Asian Tour in 2023 and has been fantastic in the continent over the past 18 months.

If Ogletree has indeed found form, he looks to be an amazing value at triple-digit odds.

Ryan: Lessons from the worst golf instructor in America

Published

6 days ago

Apr 30, 2024

Brendan Ryan

In Tampa, there is a golf course that boasts carts that do not work, a water range, and a group of players none of which have any chance to break 80. The course is overseen by a staff of crusty men who have succeeded at nothing in life but ending up at the worst-run course in America. However, this place is no failure. With several other local courses going out of business — and boasting outstanding greens — the place is booked full.

While I came for the great greens, I stayed to watch our resident instructor; a poor-tempered, method teacher who caters to the hopeless. At first, it was simply hilarious. However, after months of listening and watching, something clicked. I realized I had a front-row seat to the worst golf instructor in America.

Here are some of my key takeaways.

Method Teacher

It is widely accepted that there are three types of golf instructors: system teachers, non-system teachers, and method teachers. Method teachers prescribe the same antidote for each student based on a preamble which teachers can learn in a couple day certification.

Method teaching allows anyone to be certified. This process caters to the lowest caliber instructor, creating the illusion of competency. This empowers these underqualified instructors with the moniker of “certified” to prey on the innocent and uninformed.

The Cult of Stack and Jilt

The Stack and Tilt website proudly boasts, “A golfer swings his hands inward in the backswing as opposed to straight back to 1) create power, similar to a field goal kicker moving his leg in an arc and 2) to promote a swing that is in-to-out, which produces a draw (and eliminates a slice).”

Now, let me tell you something, there is this law of the universe which says “energy can either be created or destroyed,” so either these guys are defying physics or they have no idea what they are taking about. Further, the idea that the first move of the backswing determines impact is conjecture with a splash of utter fantasy.

These are the pontifications of a method — a set of prescriptions applied to everyone with the hope of some success through the placebo effect. It is one thing for a naive student to believe, for a golf instructor to drink and then dispel this Kool-Aid is malpractice.

Fooled by Randomness

In flipping a coin, or even a March Madness bet, there is a 50-50 chance of success. In golf, especially for new players, results are asymmetric. Simply put: Anything can happen. The problem is that when bad instructors work with high handicappers, each and every shot gets its own diagnosis and prescription. Soon the student is overwhelmed.

Now here’s the sinister thing: The overwhelming information is by design. In this case, the coach is not trying to make you better, they are trying to make you reliant on them for information. A quasi Stockholm syndrome of codependency.

Practice

One of the most important scientists of the 20th century was Ivan Pavlov. As you might recall, he found that animals, including humans, could be conditioned into biological responses. In golf, the idea of practice has made millions of hackers salivate that they are one lesson or practice session from “the secret.”

Sunk Cost

The idea for the worst golf instructor is to create control and dependency so that clients ignore the sunk cost of not getting better. Instead, they are held hostage by the idea that they are one lesson or tip away from unlocking their potential.

Cliches

Cliches have the effect of terminating thoughts. However, they are the weapon of choice for this instructor. Add some hyperbole and students actually get no information. As a result, these players couldn’t play golf. When they did, they had no real scheme. With no idea what they are doing, they would descend into a spiral of no idea what to do, bad results, lower confidence, and running back to the lesson tee from more cliches.

The fact is that poor instruction is about conditioning players to become reliant members of your cult. To take away autonomy. To use practice as a form of control. To sell more golf lessons not by making people better but through the guise that without the teacher, the student can never reach their full potential. All under the umbrella of being “certified” (in a 2-day course!) and a melee of cliches.

This of course is not just happening at my muni but is a systemic problem around the country and around the world, the consequences of which are giving people a great reason to stop playing golf. But hey, at least it’s selling a lot of golf balls…

Vincenzi’s 2024 Zurich Classic of New Orleans betting preview

Published

2 weeks ago

Apr 22, 2024

Matt Vincenzi

The PGA TOUR heads to New Orleans to play the 2023 Zurich Classic of New Orleans. In a welcome change from the usual stroke play, the Zurich Classic is a team event. On Thursday and Saturday, the teams play best ball, and on Friday and Sunday the teams play alternate shot.

TPC Louisiana is a par 72 that measures 7,425 yards. The course features some short par 4s and plenty of water and bunkers, which makes for a lot of exciting risk/reward scenarios for competitors. Pete Dye designed the course in 2004 specifically for the Zurich Classic, although the event didn’t make its debut until 2007 because of Hurricane Katrina.

Coming off of the Masters and a signature event in consecutive weeks, the field this week is a step down, and understandably so. Many of the world’s top players will be using this time to rest after a busy stretch.

However, there are some interesting teams this season with some stars making surprise appearances in the team event. Some notable teams include Patrick Cantlay and Xander Schauffele, Rory McIlroy and Shane Lowry, Collin Morikawa and Kurt Kitayama, Will Zalatoris and Sahith Theegala as well as a few Canadian teams, Nick Taylor and Adam Hadwin and Taylor Pendrith and Corey Conners.

Past Winners at TPC Louisiana

2023: Riley/Hardy (-30)
2022: Cantlay/Schauffele (-29)
2021: Leishman/Smith (-20)
2019: Palmer/Rahm (-26)
2018: Horschel/Piercy (-22)
2017: Blixt/Smith (-27)

2024 Zurich Classic of New Orleans Picks

Tom Hoge/Maverick McNealy +2500 (DraftKings)

Tom Hoge is coming off of a solid T18 finish at the RBC Heritage and finished T13 at last year’s Zurich Classic alongside Harris English.

This season, Hoge is having one of his best years on Tour in terms of Strokes Gained: Approach. In his last 24 rounds, the only player to top him on the category is Scottie Scheffler. Hoge has been solid on Pete Dye designs, ranking 28th in the field over his past 36 rounds.

McNealy is also having a solid season. He’s finished T6 at the Waste Management Phoenix Open and T9 at the PLAYERS Championship. He recently started working with world renowned swing coach, Butch Harmon, and its seemingly paid dividends in 2024.

Keith Mitchell/Joel Dahmen +4000 (DraftKings)

Keith Mitchell is having a fantastic season, finishing in the top-20 of five of his past seven starts on Tour. Most recently, Mitchell finished T14 at the Valero Texas Open and gained a whopping 6.0 strokes off the tee. He finished 6th at last year’s Zurich Classic.

Joel Dahmen is having a resurgent year and has been dialed in with his irons. He also has a T11 finish at the PLAYERS Championship at TPC Sawgrass which is another Pete Dye track. With Mitchell’s length and Dahmen’s ability to put it close with his short irons, the Mitchell/Dahmen combination will be dangerous this week.

Taylor Moore/Matt NeSmith +6500 (DraftKings)

Taylor Moore has quickly developed into one of the more consistent players on Tour. He’s finished in the top-20 in three of his past four starts, including a very impressive showing at The Masters, finishing T20. He’s also finished T4 at this event in consecutive seasons alongside Matt NeSmith.

NeSmith isn’t having a great 2024, but has seemed to elevate his game in this format. He finished T26 at Pete Dye’s TPC Sawgrass, which gives the 30-year-old something to build off of. NeSmith is also a great putter on Bermudagrass, which could help elevate Moore’s ball striking prowess.
