Additional Piece: Summary and Expansion
The cult-like following of Mark Broadie’s earned strokes concept has fueled a significant transformation in the world of golf. This statistical analysis has reshaped players’ approaches to the game, giving birth to a new breed of data-driven golfers. By quantifying the value of each shot and challenging traditional metrics, Broadie has shifted the emphasis of improvement to driving and approach shots rather than the short game.
Broadie’s impact extends beyond the PGA Tour. His book, Every Shot Counts, has opened the eyes of golf enthusiasts to a new way of understanding the game. From casual viewers to professional golfers, people are realizing the importance of data and statistics in unlocking the secrets of success on the golf course.
The concept of earned strokes has become ingrained in the sport, guiding practice sessions and tournament strategies. Players are striving to gain even the tiniest advantage, knowing that these small improvements can accumulate over time, resulting in significant differences in prize money and titles.
Looking ahead, Broadie’s work continues to shape the future of golf analysis. As technology advances and datasets become more comprehensive, the potential for continued innovation is immense. By delving deeper into analytics and incorporating broader statistical concepts, the golfing world can gain a more precise and comprehensive understanding of the game.
In conclusion, Mark Broadie’s statistical analysis has revolutionized golf, providing players and fans alike with valuable insights into the mechanics of the game. His earned strokes concept has transformed the way players approach their shots and guided their strategic decisions. As the sport continues to embrace data-driven analysis, the future of golf looks promising, with Broadie’s legacy paving the way for further advancements in statistical understanding.

In the champion’s press conference, newly crowned 2020 US Open winner Bryson DeChambeau dropped the name of an unusual golf revolutionary. “Mark Broadie was talking about . . .[how]they just made the fairways too small this week to be of any benefit to the guys hitting the fairways.
DeChambeau had just launched multiple 350-yard drives on his way to pick up the trophy, a counterintuitive strategy for a tournament that had historically valued accuracy and drudgery.
Broadie, a mild-mannered longtime decision science professor at Columbia Business School in New York City, he had invented a new statistical measure of golf more than a decade earlier, called “earned strokes.” He arithmetically disaggregates the components of a golfer’s overall score, to determine which skills are crucial to posting low rounds.
Broadie’s analysis showed that the fairways at Winged Foot Golf Club, host of the 2020 US Open, were so narrowly configured that the muscular DeChambeau might as well use his powerful tee shots to risk getting as close to the hole as possible. Even accurate drivers would be unable to avoid the thick rough, a situation made worse by being 50 yards behind DeChambeau.
Broadie’s seminal insights now pervade the game, with players guiding their practice and tournament strategy to snatch tenth shots that — over a four-day tournament and 25 tournament seasons — can mean millions of dollars in prize money. money and a series of titles.
Now in his 60s and still teaching MBA students, Broadie became a cult celebrity in the sport just two decades after he began manually tracking golf shots and entering the data into a computer program.
Traditional golf metrics — drive distance, greens hit in regulation, putts per round — called “count stats” are blunt and vacuous. For example, a player who averages minimal strokes on the green may look like a skilled putter but can also be a really great irons player who drops the ball close to the flag making short putts.
Broadie was a graduate of Cornell and Stanford before coming to Columbia, where he majored in financial engineering research. As an amateur golfer dissatisfied with traditional metrics, he realized that more meaningful stats would come from shot-level data analysis.
“The question is what is the difference between a golfer shooting 80 [yards] instead of 90,” he says. “Or what’s the benefit of hitting the ball 20 yards farther?”
Most instructors have told players that the short game — chipping and putting — is where the improvement lies. But as Broadie and his assistants analyzed the data, the biggest differences between good and bad golfers were attributable to their driving and their approach shots to the green.
The next breakthrough was to express a simple and common unit of measurement.
If a player made a 15-foot putt while the data showed that the average golfer took 1.3 strokes to pocket the ball from 15 feet, the player potting such a putt would gain 0.3 strokes on the course. The same principle could be applied to all other shots. Imagine that a 225-yard drive into a bunker for a pro on a hole would statistically require 4.7 total strokes to finish the hole. With a par 4, that means 0.7 missed shots on the field.
Just as Broadie was perfecting this concept of acquired shots, luck struck. The US PGA Tour in 2003 unveiled ShotLink, a laser technology used by volunteer spotters that tracked and memorized every shot in its tournaments. That rich dataset would become the foundation for Broadie’s hits that got a breakthrough.
While Broadie brought science, the PGA Tour understood marketing. Circuit told Broadie it was better to throw hard-earned shots to lay only early, to ease the transition. And, to get people involved, the Tour decided that instead of explaining the equations, it would simply appeal to the gut reaction of interested parties.
He showed a group of players, reporters and instructors two sets of golfers: one who had excelled at traditional putting stats and then the other who topped earned strokes, asking which resonated as the best putters.
The judges almost unanimously chose the pool of earned strokes and a brave new world was suddenly upon golf. Gamers who had been strictly instinctive were suddenly data-geeks. And those who had already been solitary number chewers found a kindred spirit in Broadie. Edoardo Molinari, a veteran of the European tour who had studied engineering in college and had long relied on his homemade statistical models of his game, had befriended Broadie more than a decade ago. “The details are so small. You can’t observe them, you have to go deeper: in this era, using stats is vital.
“The first time I read Mark’s book, Every shot countsit changed the way I look at golf,” says Chris Solomon, co-founder of the popular golf podcast No Laying Up.
“Those of us who watch golf for a living, maybe see 10% of a top player’s shots in a year. Earned shots can tell us why Justin Thomas is falling backwards and what makes Scottie Scheffler so outrageous.
Scheffler, the current top golfer in the world, is earning nearly three shots per round from drives and approaches this season—a superiority so vast that his overall bad earned shots in putts haven’t stopped him from multiple wins this season. season.
That kind of precise understanding is exactly what Broadie had hoped for. He likens the hits earned to financial analysis, which uses concepts like alpha and the Sharpe Ratio that can highlight outperformance.
“It’s great,” says Broadie, reflecting on this contribution to the understanding of golf. “I’ve always had a goal of ideas that have an impact.”
