I keep track of the radar metrics on the PGA Tour each week, and so far this season I’ve started to see some noticeable differences in the radar data being produced by the field than I have in years past. So I decided to look at the Tour averages for each season since the Tour started to record the radar data back in 2007.
Here’s a chart showing those averages each season.
To draw an even clearer picture, here’s a comparison between this season’s radar metrics and the inaugural season in 2007.
While the club speed and ball speed have picked up, the larger differences are in the Max Height and Spin Rate metrics. The other two factors that have seen a marked change are Smash Factor and Carry Efficiency, which are calculated using the formulas below.
- Smash Factor = Ball Speed / Club Head Speed
- Carry Efficiency = Carry Distance / Club Speed
While the percentage difference between these two metrics is smaller than the other metrics, we have to remember that USGA rules have a certain allowable Smash Factor that is roughly 1.50. So there is a ceiling with regards to Smash Factor and the same goes for Carry Efficiency.
What this shows is the effect that launch monitors have had on PGA Tour swings, as well as the golf equipment industry, which has been producing metal woods that launch the ball slightly higher and with less spin in recent years. I can also conclude from the metrics that fewer players are hitting their driver with a severely downward attack angle (-4 degrees or steeper), because:
- Their launch angles are up.
- Their carry efficiency is up.
- Their max height is significantly up.
- Their spin rate is down.
According to Trackman, with all things being equal, the lower a golfer’s Spin Loft the higher the Smash Factor. Spin Loft is a measurement of a golfer’s dynamic loft, which is the amount of loft they deliver to the ball at the moment of maximum ball compression, minus a golfer’s angle of attack, as shown below.
- Spin Loft = Dynamic Loft – Attack Angle
So if Tour players are less steep with their attack angle and their dynamic loft is roughly the same, the Spin Loft has now decreased and that allows for a higher Smash Factor.
What is probably most interesting is that higher club-head speed players have resorted to more of an upward hit on the ball. In the past, the high club-speed players almost exclusively kept their launch low so they could keep the max height low and better control their drives. They would generally have a launch angle between 9 to 10 degrees with about 2,800 rpm of spin. Now, we see some of the higher club-head speed players on Tour with very high launch angles and low spin rates.
Two prime examples of this are rookies Justin Thomas and Patrick Rodgers, both of whom are 22 years old. It should be noted that Rodgers and Thomas are ranked Nos. 1 and 2 in Max Height, respectively.
Currently, Thomas ranks 73rd (out of 203 golfers) in my Driving Effectiveness ranking, while Rodgers ranks 59th. There is not a lot of data with regards to higher-speed players who produce very high launch numbers over a significant period of time, but the long hitters who are generally more effective off the tee average lower launch numbers like Bubba Watson, who currently first in Driving Effectiveness.
I suspect that eventually players like Thomas and Rodgers will bring down their attack angles a bit in order to create a lower launch, a lower max height and a higher spin rate so they can drive ball more accurately and precisely like Bubba does. But young guns like Thomas and Rodgers, as well as the Tour radar statistics as a whole, show the great influence that launch monitors are having on the best golfers in the world.
TG2: Should Tiger Woods play in The Masters without a driver?
Tiger Woods’ No. 1 concern heading into the Masters is the driver, according to Notah Begay. Equipment expert Brian Knudson and Editor Andrew Tursky argue whether Tiger should even use a driver during the Masters. Also, they discuss Rory’s new prototype putter and how it was made, and they talk about a new shaft company called “LA Golf Shafts.”

Book Review: The Life and Times of Donald Ross
The Life and Times of Donald Ross is a successful golf history, in that it holds one’s attention, regardless of one’s level of enthusiasm or interest for the subject. It can hardly avoid doing so, as it traces the life of a man who lived through both world wars, emigrated from the old country to the new, and championed a sport that grew from infancy to maturity in the USA, during his earthly run. The loss of two wives to uncontrollable circumstances, the raising of a child essentially on his own, and the commitment to the growth of golf as an industry add to the complexity of the life of Donald J. Ross Jr. Within the cover of this tome, through words and images, the life and times of the man are communicated in fine fashion.
The book was published in 2016, by Chris Buie of Southern Pines, North Carolina. Buie is not a professional writer in the traditional sense. He does not solicit contracts for books, but instead, writes from a place of passion and enthusiasm. This is not to say that he is not a writer of professional quality. Instead, it isolates him among those who turn out high-level prose, scholarly research, with attention-holding results.
Before I opened the book, it was the cover that held my attention for much longer than a single, fleeting moment. The solitary figure, staring out across the ocean. Was he gazing toward the Americas, or toward his birthplace, in Scotland? And that blend of blue shades, like something out of Picasso’s 1901-1904 period of monochromatic azures, proved to be equal parts calming and evocative. Those years, by the way, correlate with the 29th to the 32nd years of Ross’ life. During that period, Ross lost a brother (John) to injuries suffered in the Boer War, and married his first wife, Janet. With care like that for the cover art, what marvelous research awaited within the binding?
After a number of readings, I’m uncertain as to the greater value of the words or the pictures. Perhaps it’s the codependency of one on the other that leads to the success of the effort. The book is the culmination of 5 months of exhaustive research, followed by 7 months of intense writing, on Buie’s part. The author made up his mind to match as many images as possible with his descriptors, so as to create both visual and lexical collections to stand time’s test. Maps, paintings, photos, newspaper clippings, postcards, etchings and course routes were collected and reproduced within the covers. Throughout the process, so much of Ross’s life and craft, previously unrecognized in publication, were revealed to Buie. Ross’s ability to make the unnatural look natural when necessary, is hardly equaled in the annals of golf course architecture. According to Buie,
Growing up all I’d heard was natural. Certainly he incorporated as much of the existing terrain and environment as possible. But given how much other work went into the courses, it would be more accurate to say his courses were naturalistic.
Buie also scrapes away at the misplaced notion that Ross was a one-dimensional golf course architect. After all, what else did Shakespeare do besides write plays and sonnets? Well, Ross did so much more, in addition to building some of the world’s great member and tournament golf courses, shaping the Pinehurst Resort experience, and running an in-town hotel in the process. Again, Buie comments,
His greatest contribution was the role he played in the overall establishment of the game in the United States. He was involved in every aspect (caddymaster, greenkeeper, teacher, player, mentor, tournaments, clubmaking, management, etc). The theme that went through his efforts was that he was adamant all be done “the right way”. Given the breadth and enduring nature of his efforts I don’t think anyone else did more to establish the game in America. That makes him the “Grand Old Man of the American Game” – not just a prolific architect.
What was it about Ross, that separated him from the many compatriots who journeyed from Scotland to the USA? They were content to compete and run golf clubs, but Ross sought so much more. His early years involved much successful competition, including top-10 finishes in the US Open. He was also a competent instructor, manifested in the ability of his students to learn both the swing and its competitive execution. And yet, Pinehurst is so different from any other place in the Americas. And so much of what it is, is due to the influence of Donald Ross.
In a nod to the accepted round of golf across the planet, the book contains 18 chapters, including the appendices. At locomotive pace, the mode of transportation utilized by Ross to traverse the lower 48 of the USA and Canada, the reader gathers a proper awareness of the great man’s living arc. Beginning with the hike from the train station in Boston to the Oakley Country Club, the emigration of the Scotsman from the highlands of Caledonia to the next hemisphere was a fairly simple affair, with unexpected, poignant, and far-reaching consequences. Donald J. Ross, jr., would complete the shaping of american golf that was assisted (but never controlled) by architectural peers. Men like Walter Travis, Albert Tillinghast, Charles Blair Macdonald, Alister MacKenzie and Tom Bendelow would build courses of eternal worth, but none would shape in the far-reaching manner of Ross.
It’s tempting to make a larger portion of this story about Buie, but he wouldn’t have it so. A Pinehurst native, Buie’s blend of reverence and understanding of his home region are evident and undeniable. One almost thinks that a similar history might have been written about any number of characters charged with the stewardship of the Sandhills region of North Carolina. Fortunately for aficionados of golf and its course architecture, Buie is a golfer, and so we have this tome.
Donald J. Ross, jr. was a man of principle, a man of faith, a man of belief. When those beliefs came into conflict with each other, which they seldom did, he had an instinct for elevating one over the other. No other place is this more evident that in his routing of the Sagamore course in Lake George, in the Adirondack mountains of New York state. Faced with the conundrum of how to begin the course, his daughter remembers the sage words of the father. Despite contradicting his belief that a course should never begin in the direction of the rising sun, Ross commented I can’t start it anywhere but looking out at that lake and those mountains. Indeed, Sagamore would be a poorer place for an alternate opening, and this review would have less of a way to reach its end.
My recommendation: read the book.
Kingston Heath: The Hype is Real
We touched ground late in the afternoon at Melbourne Airport and checked in very, very late at hotel Grand Hyatt. Don’t ask about our driving and navigating skills. It shouldn’t have taken us as long as we did. Even with GPS we failed miserably, but our dear friend had been so kind to arrange a room with a magnificent view on the 32nd floor for us.
The skyline in Melbourne was amazing, and what a vibrant, multicultural city Melbourne turned out to be when we later visited the streets to catch a late dinner. The next morning, we headed out to one of the finest golf courses that you can find Down Under: Kingston Heath. We had heard so many great things about this course, and to be honest we were a bit worried it almost was too hyped up. Luckily, there were no disappointments.
Here’s the thing about Kingston Heath. You’re driving in the middle of a suburb in Melbourne and then suddenly you see the sign, “Kingston Heath.” Very shortly after the turn, you’re at the club. This is very different than the other golf courses we’ve visited on this trip Down Under, where we’ve had to drive for several miles to get from the front gates to the club house.
Nevertheless, this course and its wonderful turf danced in front of us from the very first minute of our arrival. With a perfect sunrise and a very picture friendly magic morning mist, we walked out on the course and captured a few photos. Well, hundreds to be honest. The shapes and details are so pure and well defined.
Kingston Heath was designed by Dan Soutar back in 1925 with help and guidance from the legendary golf architect Dr. Alister MacKenzie, who added to its excellent bunkering system. Dr. MacKenzie’s only design suggestion was to change Soutar’s 15th hole from a 222-yard par-4 (with a blind tee shot) to a par-3. Today, this hole is considered to be one the best par-3 holes Down Under, and I can understand why.
I am normally not a big fan of flat courses, but I will make a rare exception for Kingston Heath. It’s a course that’s both fun and puts your strategic skills to a serious test. Our experience is that you need to plan your shots carefully, and never forget to stay out of its deep bunkers. They’re not easy.
Kingston Heath is not super long in distance, but it will still give you a tough test. You definitely need to be straight to earn a good score. If you are in Melbourne, this is the golf course I would recommend above all others.
Next up: Metropolitan. Stay tuned!
