The data behind Luke Donald’s decision to change instructors
Luke Donald recently made an instructor change to Texas-based swing coach Chuck Cook.
Back in 2011, Donald had an epic season. He finished first on the PGA Tour money list and the European Tour’s Order of Merit. He also became the No. 1-ranked golfer in the world. So the next obvious step for Donald was to win a major championship. But the fine play he exhibited in 2011 rarely resurfaced in 2012. He regained some of his old magic in 2013, but not enough to leave him satisfied.
So, what has happened to Donald’s game to make him switch instructors? First, let’s take a look at some basic scoring analysis, comparing his 2011 season versus his 2013 season.
The order of importance of these metrics when it comes to mathematically correlating to success on Tour is as follows:
- Par-4 Scoring Average
- Bogey Rate
- Par-5 Scoring Average
- Birdie Rate
- Par-3 Scoring Average
So, the major drop-offs were in metrics Nos. 2, 3 and 4.
Bogey Rate is the most important metric here. Having a low Bogey Rate is about two aspects of the game:
- Being able to save par.
- Being able to hit your approach shots close to the hole, where it greatly decreases the odds of making bogey.
The latter is what many golfers do not understand about why Bogey Rate is more important (from a mathematical standpoint) than Birdie Rate. The best way to avoid bogeys is to not put yourself in position to make them. Even the worst putters in the world are not going to make bogeys if they hit 16 or more greens per round and have an average birdie putt of less than 20 feet.
With that said, let’s take a look at Donald’s key performance metrics of 2011 versus 2013:
First, we should acknowledge that Luke’s 2011 season could very well never be replicated again. He ranked No. 1 on shots from 75 to 125 yards and shots from 125 to 175 yards. He also ranked first in Putts Gained. It is no small wonder why he played so brilliantly in 2011; if he had an approach shot from 175 yards or less he was by far the best player in the world. And if he was farther than 175 yards away from the hole, he was very good.
With that said, we start to see a noticeable difference in his play on the longer approach shots. When we examine it more closely we start to see a fairly large regression. Here are Donald’s rankings on long approach shots from the fairway/tee box in 2011 versus 2012.
This would explain the increase in Bogey Rate. Longer approach shots, particularly those from the Danger Zone, is where golfers tend to put themselves in position to make a bogey or a double bogey. Donald has seen a fairly large drop off on shots from 150 to 175 yards, but a massive drop off on shots from 200 to 225 yards.
Donald has never been very effective off the tee since he has been on Tour. In fact, his 2011 season (where he finished 132nd in Driving Effectiveness) was his best year with the driver on Tour. I believe that is what has held him back from winning a major, and why a course like Augusta National ends up fitting him the best out of all of the majors championship venues. It is very much an approach-shot-oriented course, and one where putting is extremely important. The other majors often require more precise and effective driving of the ball. The drawback is that Augusta also favors long hitters, which hurts Donald’s odds of winning a major there.
I would imagine that part of the change to a new instructor was that Donald hoped he could improve his tee play. At his club-head speed and distance off the tee, he needs to be able to hit about at least 68 percent of his fairways and get his Average Distance to the Edge of the Fairway to around 22 feet or less. Here is Donald’s data in these metrics during the past four years:
While Donald is not very far away from hitting 68 percent plus of his fairways and having an average Distance to the Edge of the Fairway of 22 feet or less, it goes to show that the slightest discrepancy can be the difference between being forecasted to win a major or two and having yet to win a major.
What I find interesting about Donald’s driving is in the radar data. Last year, there was a launch monitor report circulating on the web of Donald’s impact data. The launch monitor had Donald with a 2.5-degree downward attack angle with the driver. However, if you look at his radar metrics for this year on Tour there are some things that do not quite add up.
What we know about downward attack angles with the driver is that they result in golfers not hitting the ball as high or as far as they normally would with a “flat” attack angle or an upward attack angle. Furthermore, the downward attack angle will produce a higher spin rate.
What we see is that Donald’s distance ranking is noticeably worse than his ranking in clubhead speed. That is part of what we would logically assume given his downward attack angle. Furthermore, he has the 19th highest Spin Rate on Tour (2,922 RPMs). This is also in line with a golfer that hits the ball with a downward attack angle with the driver.
However, there are some contradictory metrics. His launch angle is fairly high (11.25 degrees), and he has the 41st highest ball flight on Tour. And as we know, higher clubhead speed players will generally hit the ball higher as well. Donald is a lower clubhead speed player who has a high ball flight. He is also doing it with a fairly high launch angle, but the spin rate is high.
I think the key piece to this is his ranking in Smash Factor (91st). And I believe what is happening for Donald is that he is hitting above the “sweet spot” on his driver. Tom Wishon has discussed how hitting above the “sweet spot” affects the ball’s flight with this diagram.
Drivers are not designed to have a perfectly flat face. They have something called “vertical face roll,” which means that the face of the driver has a bulging design and the bulge runs horizontally (face bulged) and vertically (face roll).
With the larger 460cc drivers, this produces a club where if the golfer hits below the “sweet spot,” there is less loft. Conversely, if the golfer hits above the sweet spot, there is more loft. From there, the horizontal gear effect comes into play and if the golfer hits the ball above the sweet spot, that means the gear effect will reduce the spin on the ball.
Here are Donald’s radar metrics during the past four years.
Perhaps changes in equipment are a reason behind Donald’s unorthodox radar numbers given his 2.5-degree downward attack angle. But, his spin rate has lowered while his trajectory has gotten higher. And he still has an issue with getting his distance off the tee to match his club-head speed.
Donald will have his work cut out for him. But if he can get his long approach shot play back to his 2011 performance he will be very close to his old form. And if he can figure out his driving woes on top of it, he can be even better than he once was.

AVL: We’re talking about practice! My best tips for taking your game to the course
With the beginning of June on the horizon and courses rounding into peak condition for the season, it’s time to hone the finer skills that often get rusty over the winter. More sunlight also means more time to get out on the course and work on your game.
Whether it’s the practice green or the driving range, there’s always something to improve—whether you’re enjoying the fresh air or preparing for a weekend game or tournament. You can work on drills or freestyle around the green, and friendly competition is a great way to sharpen your skills.
While there are endless ways to get better at golf, I’m going to focus on practicing around the green. Let’s take a look at a few things to keep in mind as we head into the summer months.
Drills
From the driving range to the practice green, it’s important to incorporate drills into your routine. Years ago, I spent a weekend working on my short game with James Sieckmann. He recommended doing drill work for 5–10 minutes, then returning to your main practice.
This way, you create a balance between structured drills and real-world scenarios, so you’re not confined to “perfect” situations. For example, hitting the same three-foot putt over and over is good for repetition, but after a while, it becomes less interactive for your brain.
My approach is to use a putting trainer with a narrow gate for the ball to pass through, or simply place tees just outside the width of the ball. I’ll hit a series of four putts through the gate for three sets. Then, from a similar distance, I’ll hit four putts without the training aid and repeat that sequence three times.
Next, I’ll hit a number of 15–25 foot putts in a random fashion, then circle back to repeat the short putt drills with and without the training aid.
This breaks up the rhythm of hitting short putts with the training aid. When you hit the same short putts over and over, it’s easy to get into a groove—which is great for the drill, but not reflective of actual course play. While finding a rhythm is fundamental for drills, I like to introduce variation with longer putts to keep things realistic.
Game Mode
Once you’ve established a foundation with drills, it’s time to simulate on-course scenarios. This is where a few practice games come in handy.
One that I’ve been enjoying lately involves putting 10- to 15-footers with two balls. If I make the putt, great! If I miss, I pull the missed ball back a putter length. Suddenly, that little tap-in becomes a nerve-wracking three-footer—at least at first. As you get better at this game, those three- and five-footers become much more comfortable and routine.
It may sound cliché, but each shot is just what it is—it’s how we react that makes the difference. I like this game because it blends the pressure of on-course putting with the consequence of leaving yourself a much longer putt than usual.
Another game I like is one I recently learned from Brad Faxon. Place three tees in a line at four different locations around the hole: one at 3 feet, one at 6 feet, and one at 8 feet. The 3- and 6-foot putts count as par, and the 8-footer is for birdie.
This game keeps you focused on scoring and helps you get into a competitive mindset. You can even think about this putting game while you’re on the course. I just started playing it, and last week I couldn’t get better than two under par.
Competition
Competition during practice is when drills and games come to life, and you start to see results. For me, nothing beats a putting contest with a friend or two. In the right setting, these contests can become talking points for the whole season.
Match play, a game of 21, or simply seeing who can make the most one-putts (with a small prize on the line) are all great ways to simulate real on-course pressure. Recently, I played in a putting contest where one competitor made back-to-back 30- and 50-foot putts. As they say, expect your opponent to make every putt—and he nearly did. That’s impressive, and it’s something you see on the course, too: you have to stay committed to your game plan, no matter what.
When it comes to practice, it’s important to blend feedback from recent rounds with the fundamentals you want to reinforce. Drills, games, and competition—from the driving range to the putting green—form the backbone of skills you’ll rely on during actual rounds.
Finding the right balance is something we’re all working on, one practice session at a time. With the beginning of June on the horizon and courses rounding into peak condition for the season, it’s time to hone the finer skills that often get rusty over the winter.

Seoul Sensibilities: Is Korean golf fashion starting to shape the world?
For Korean golfers, we always look forward to the last of the kkot-saem-chu-I for the true start of a new golf season. The term refers to a cold snap, but literally translates as “winter being jealous of the flowers beginning to bloom, thus lashing out one final time before surrendering to spring”.
A rather poetic mouthful packed into a short expression.
Koreans can be like that. Understated, yet oddly expressive at the same time. And nowhere is this more true on the golf course and in our golf bags. In fact, I suspect many Korean golfers look forward to new apparel and accessory drops more than they do actual equipment launches each year.

At this point, Korean golf fashion may exist on its own timeline. (courtesy of @seonbi_golfer)
There is ample evidence to support that suspicion. Korea is the world’s third-largest golf market behind the United States and Japan, yet its appetite for golf apparel exceeds that of both countries combined. Recent estimates suggest that Korea accounts for nearly 40 percent of the global golf apparel market, placing it among the world’s most influential golf fashion markets and punching well above its size.
Simply, we care deeply about how new golf clubs look and feel, but enjoy looking good while swinging them even more.
Golfers in the West may laugh and say that golf is played on a course, not a fashion runway. Perhaps. But what’s the harm in trying to look and feel good, if the added self-confidence can help actual performance? It certainly seems to have worked for Jason Day, who may have unlocked a new stats category: dormant strokes gained. Coincidence?

During the COVID-era, estimates placed the market near $9 billion, an astonishing figure for a single country.
As a proud member of Gen X, I’ve witnessed the highs and lows of golf fashion firsthand. The pleated trousers and wing-tipped shoes of Jack Nicklaus, the stylish plus-fours and knickers of Payne Stewart, the baggy black trousers and fitted mock-necks of Tiger Woods, and the thigh-hugging athletic tailoring of Rory McIlroy. Golf fashion, like the golf swing itself, has rarely stood still.
But nowhere have those trends shifted, evolved, and been scrutinized quite as relentlessly as in Korea. Here, golf fashion moves faster than fairway gossip, and consumers dissect brands with a level of discernment that can be both impressive and mildly terrifying. New brands are studied, judged, embraced, or dismissed with startling efficiency.
The result is a consumer base with one of the sharpest eyes for quality and authenticity anywhere in the world. It is difficult to quantify, but easy to recognize. Clean lines without trying too hard. Luxury mixed with utility. Trend awareness balanced by restraint and purpose.
It’s golf fashion shaped by one of the world’s most style-literate cities, something I like to call Seoul Sensibilities, referring to the taste level forged by a uniquely competitive environment.
And increasingly, global brands have noticed.

Many golf brands in Korea have their own flagship shops dedicated to apparel only
Titleist understood this years ago, when its apparel business in Korea took on a life of its own under new ownership and local direction. What had once been a straightforward extension of an iconic equipment giant became something sharper and more premium. By going all in on the serious Tour-player look (I couldn’t even fit into their XL sizes), Titleist struck the right chord with Korean consumers and helped its fledgling apparel business break into the mainstream. Titleist became a household name even for non-golfers who wore its caps, shirts, and windbreakers in daily life. In many ways, it proved that even heritage golf brands could carry real fashion credibility when viewed through a Korean lens.
Several years later, PXG took a page out of Titleist’s playbook and followed suit. Korean consumers helped transform the brand from one known largely for irons and loud commercials into something broader and more stylish. PXG apparel’s growth in Korea was explosive, where it found an early audience and turned the category into something more than mere logo merchandise. It is still hard to walk anywhere in Seoul without seeing its palindrome logo.
Malbon’s meteoric rise in the United States was genuine, but its ascent into a global golf lifestyle brand owes much to Korea, where it was elevated by a market already fluent in modern golf style. Korea did not simply embrace Malbon. It pressure-tested the concept, refined its appeal, and helped push it into the global spotlight.
As such, new brands may arrive from abroad, but more often than not, their sharpest evolution happens here. If a brand can earn credibility in Seoul, it’s deemed to have passed one of the toughest style audits in the game.
That is why the next meaningful chapter may not come from outside, but from a Korean brand moving in the opposite direction, carrying those Seoul Sensibilities outward as K-pop once did.

Play young Stay dope.
From Seoul, With Intent
Khalhon is a label that feels less like a trend-chasing newcomer and more like the product of a market that has already seen everything. Golfers here have long been surrounded by luxury logos, technical fabrics, and tour uniforms disguised as lifestyle wear and vice-versa. In other words, novelty alone rarely lasts here, and the Koreans seems to understand that instinctively.
Its style language leans into clean silhouettes, relaxed but tailored proportions, muted palettes, and premium materials that speak quietly but confidently. There is a modern city aesthetic running through it all, with strong layering pieces, thoughtful textures, and subtle branding that suggests sophistication rather than demanding attention.

“Built for the course. Designed beyond it.”
Most importantly, the garments seem designed to blur the line between golfwear and everyday style. Shirts, trousers, knitwear, and outer layers move comfortably between a game of screen golf, a lunch reservation, an airport gate, or an afternoon coffee in Gangnam with friends.
It raises the question of whether this is golfwear that happens to look good off the course, or everyday clothing that performs beautifully on the fairways.
Personally, I have long appreciated Nike Golf for its clean, athletic modernization of golf attire. It also has the useful side effect of making me look like a more serious golfer than I probably am. But off the course, there are times when being instantly identified as the golf guy in a crowd of non-golfers can feel a touch self-conscious.

“Built for the course. Designed beyond it.”
That is part of what drew me to Khalhon, which seemed to blend golf and everyday wear naturally. While some of the outfits may be slightly beyond my personal confidence level, the brand also offers tasteful options for older guys like me who still want to express a little personality without regretting the decision later.
These are not simply flashy outfits worn on the course and then banished to the closet until the next tee time. They work surprisingly well off the course too, and I suspect many of the pieces will still look right a couple of years from now, which would certainly be kinder to my wallet than most golf fashion trends tend to be.
And perhaps that broader lifestyle positioning also helps explain why someone like Sean Wotherspoon would find Khalhon creatively interesting in the first place.

“Built for the course. Designed beyond it.”
“Korea is not only one of the most fashion-forward golf markets in the world, but one of the most fashion-forward markets globally. Korea is ahead, and I love to watch and try to catch up.” – Sean Wotherspoon, Creative Director at Khalhon
Seoul and Beyond
If Khalhon’s rise says something about where Korean golf fashion is today, its relationship with Sean Wotherspoon says even more about where it is heading.
For readers less familiar with Sean Wotherspoon, his arrival at Khalhon is not some routine celebrity endorsement or influencer collaboration. In design and streetwear circles, Wotherspoon is regarded as one of the more influential creative voices of his generation, particularly when it comes to blending nostalgia, storytelling, and contemporary culture into products that people can connect with.
He first gained widespread attention through his now-famous Nike sneaker collaborations, where his vintage-inspired designs and instinct for color helped turn him into one of the defining artists of the late-2010s sneaker era. His work gradually expanded beyond footwear into apparel, automotive collaborations, collectibles, and broader lifestyle design.
Modern golf style now extends well beyond the fairways, where performance and functionality are largely expected by default. And while plenty of brands already make technically competent golfwear, Khalhon seems more focused on designing clothes people would genuinely want to wear even after the round ends.
And when guys at Wotherspoon’s level show genuine interest in working with a Korean golf brand as its new Creative Director, fashion circles tend to sit up and pay attention. There’s already a huge buzz among the fashion-conscious here about upcoming collabs with iconic sports stars and brands.

“My creative direction for Khalhon is disruptive, colorful, nostalgic, and modern. My goal is to blend these avenues seamlessly within each collection.” – Sean Wotherspoon
In chatting with Sean, what stood out most to me was how genuinely energized he sounded about the project itself. Despite having already worked across and countless other creative spaces, he described golf as a completely fresh category for him, saying that Khalhon “will be an amazing vehicle for my design work.”
At the same time, his enthusiasm seemed tied just as much to Korea itself. He spoke openly about admiring Korea’s fashion culture while repeatedly insisting he is still a terrible golfer.
There was something oddly refreshing about that humility. Rather than sounding like a celebrity parachuting into golf simply because the category suddenly became fashionable, Sean sounded genuinely curious about what Korea might do with the category next.
And perhaps that is what makes Khalhon feel interesting right now. The brand feels less like a trend-chaser and more like the natural result of a market now confident enough to export its own point of view.
For years, global brands came to Korea to sharpen their image against one of the most discerning audiences anywhere. Now, a Korean label appears ready to send those Seoul Sensibilities outward instead.
Which brings us back to kkot-saem-chu-i.
That final cold snap before spring always arrives with a reminder that seasons are changing, whether we notice it immediately or not. Golf fashion feels a little like that right now as well, as the old boundaries between sport, streetwear, luxury, and everyday style continue to soften.
And somewhere in Seoul, a Korean golf label already seems prepared for whatever season comes next. I just hope they have everything in my size.

whats the significance of distance to edge data?
isn’t it possible, if not probable, that these pros intended to land the ball on certain spots of the fairway?
middle of the fairway is not always the best spot for second shot
Richie Hunt
Oct 14, 2013 at 3:08 pm
Distance to the Edge of the fairway is based on shots that *miss* the fairway. The significance is it helps measure how large a player’s misses are.

No argument Donald is a very good player-but he’s not a great player. He has strengths, but he also has big weaknesses (162nd in ball striking in 2013).
The key stats are 251 PGA Tour starts, 5 wins, 0 Majors-a very nice career but not World no.1 material…

Really appreciate the analysis of the info!
The huge drop in 150/175 and 200/225 accuracy is easy to see.
Looks like the 2011 Irons are worth going back too……..
I got into a negative impact around 2 degrees around xmas
after being a +- Zero degrees hitter…took a while to fix!

Very interesting!
Did he also change balls during this same period? Has the change in the ball affected the numbers that much?
The driver change obviously has affected it, for sure, but I wonder about the ball itself too. I wish there was some kind of machine that could tell us bit more about compression data of balls at impact besides just the Trackman smash factor data.
How about the shaft? Did he change shaft when he changed the head?
We all know that he also struggled with the change from the MP-62 to the 64.
Obviously if his proximity to the hole suffers he has to work harder on the greens so the putting suffers and it shows.
Nothing wrong with having a new set of eyes take a look at you. I hope he makes a good comeback next year.
Richie Hunt
Oct 3, 2013 at 2:07 pm
I don’t know if he changed golf balls or shaft, etc. That’s why I stated that perhaps the equipment causes his unorthodox radar numbers with the driver.
Putts Gained is based on putts made percentage, BUT with relation to the field. And it’s where the golfer putts from. So not hitting your irons as well is technically separate from Putts Gained because it’s basing it on your ability to make putts from certain distances. If you’re leaving yourself with 20 foot putts instead of 10 foot putts, obviously…you’ll make less putts. But, that doesn’t matter in putts gained because it’s testing how well you can make those 20 foot putts (in this example) versus how well the field does from 20 feet.

If you already know that…why are stating the hitting down creates backspin when you clearly know that it doesn’t?
naflack
Oct 3, 2013 at 8:55 am
Sorry but that makes no sense…
I watched the maestro explain the entire thing.
I’ll trust his explanation over yours, it’s makes more sense.
Besides the fact that trackman data tells us that hitting down does not create spin by itself. Otherwise guys who hit down with their drivers would need less loft not more.
I don’t understand with your knowledge how you draw such a conclusion that the player exhibited alone disputes?

If by “hitting down” you mean increasing downward angle of attach while also tilting the club face down by the same amount, you’re right, no change in spin rate. But if your angle of attack is increased downward while the clubfaces remains the same, result is higher spin rate.
So, if Donald knows he should have a launch angle with a driver of about 11-12 degrees, and is changing the driver static loft to achieve it while using a -2.5 deg AoA, the spin will increase. He should do the opposite to increase distance…raise AoA, but use loft that continues to get about 11 degrees of launch angle.

i wonder how many golfers understand the subtext involved, im guessing not many…

I can guarantee you that Trackman Maestro would agree with me that dynamic loft by itself (as well as attack angle) will not increase the spin rate. It’s the increase in the difference between AoA and dynamic loft, otherwise known as Spin Loft, that increases or decreases spin rate.

im sure he would agree with the above premise…
i dont however believe he would agree with the statement in the article that downward angle of attack increases spin rate.
ive watched his videos, he states over and over again that the statement “hitting down increases spin” in and of itself is a myth. the distinction is important because the average golfer doesnt understand the difference between hitting down and spin loft. they see hitting down increases spin when unless they know how to do it properly it oly hurts their game.
perhaps im the idiot and all the readers know the distinction, either way i felt the need to comment and appreciate your responses none the less.

I think we typically see golfers generating more spin when they hit down because their spin loft is *likely* to increase. They may bring their dynamic loft down with it, but generally not enough to keep the spin loft consistent (at least IMO).
The real point of that portion of the article was to explore Donald’s struggles with the driver over his career. I don’t know his average dynamic loft, but I did know his average attack angle. What I found interesting was his launch angle would increase and he had very unorthodox numbers when we look at his club head speed, spin rate, max height, distance, etc.
It could be an equipment thing, but it could be where he is hitting the ball. And I’ve worked with a couple of clients that changed how high they tee the ball up and that has affected their radar metrics and subsequently their driving off the tee.
I usually try to tie these articles in with what the average amateur could possibly learn. There’s a popular myth that hitting above the sweet spot on the modern driver is a ‘hot spot’ on the driver. It’s actually not and I was trying to bring that to the attention of the reader and show a possible case of where this may be detrimental to a player like Luke Donald.

downward angle of attack DOES NOT produce a higher spin rate, more dynamic loft produces a higher spin rate.
the fact that he is as high as 19 in spin rate indicates that hitting down with the driver isnt increasing his spin rate.
dont believe me…google “track man maestro” then watch him on youtube.

Sorry, but that’s incorrect. Dynamic loft by itself does NOT produce a higher spin rate. It’s about Spin Loft which is the difference between the Dynamic Loft and the Attack Angle. So all things being equal, if the attack angle gets steeper the spin loft increases and thus the spin rate increases. Conversely, all things being equal…if the dynamic loft increases the spin loft increases which means the spin will increase.

Rich thank you for sharing your analysis of Luke Donald’s current challenges with his game.
With the wealth of statistical data available to us it is fortunate that we have people like yourself who can drill down into the data and present it in a way that makes sense.
I wonder whether Luke Donald will be able to change his game enough to improve the numbers you suggest if he has to change some aspect of his golf swing.
I imagine that someone as knowledgeable and experienced as Chuck Cook will guide him carefully, but as someone who works with tour players and elite amateurs helping them to improve their numbers in key areas of their game it’s indeed a slippery slope.
Get it wrong and even great golfers are lost to the golf swing change wilderness, but get it right and Luke Donald might be able to bag himself a major or two.
Only time will tell. Thanks again for an insightful article.
