QA Stimpmeter Simplified

Editor's Note: This is the latest in a weekly Q&A feature from The Golf Channel's Chief Technical Advisor Frank Thomas. To submit a question for possible use in this column, email letsbefrank@thegolfchannel.com
 
Hi Mr Thomas,
I believe you had something to do with green speed measurement standards. Can you tell me how the green speed is measured what were the green speeds at the U.S. Open at Winged Foot? - George M.

 
George,
Yes I did have something to do with the Stimpmeter and you can read about it on www.franklygolf.com under Frankly Speaking The Birth of the Stimpmeter. The concept design was to develop a quantitative measure of the speed of greens. Prior to the adoption of this device as an official measure of green speeds it was left to somebodys memory and personal experience about how fast greens should be.

Briefly the device consists of a grooved stick with a notch in it to hold a golf ball. When raised at one end closest to the notch with the other end resting on the surface of the green at a certain point (20 degrees tilt) the ball will release and roll down the groove. It will contact the green with the same kinetic energy every time relying on gravity and the slope of the stick (Stimpmeter). When it reaches the surface of a flat spot on the green it will roll for some distance depending on the speed of the green. This measurement -- in feet -- is measured and reported as the speed of the green.
 
The speed can be controlled by rolling and also the height of the cut when the green is mowed.
 
The greens at the U.S. Open this year were right at 12 feet, which is about as fast as they could have been given the undulations of the greens.
 
The Stimpmeter reading is now the International Standard for measuring green speeds, and I am very proud of this.
 
Hi Frank,
If I carry less than fourteen clubs, is it legal to change the weights in my driver during a round. - JC, Denver

 
JC,
The answer is NO as you are not allowed to adjust a club during a round. The fact that most of the latest adjustable drivers have four weight ports, the number of different adjustments you can make will be greater than the number of clubs you have in your bag. So even if you were to use the 13 clubs as an excuse to adjust your club you would violate the fourteen club rule.
 
The rule requires that if a club is designed to be adjustable the adjustment be made with a special tool not normally carried by a golfer, such as a spike wrench or a ball mark repair tool. This is to take temptation away from the golfer making an adjustment during a round.

JC good try but NO.
 

Frank
Do golf balls have a shelf life? Will playing with ball one or two years old, but never hit reduce it performance or distance? -- Thank You, Jack in N.C.

 
Jack,
Golf balls do not have a shelf life that you need to worry about.
 
I say this because balls will deteriorate slower than technology is advancing and even though technology is still moving along very slowly by the time your balls are affected by age (about 15 to 20 years) you may want to look at something with newer technology. The advances that will be made will not be in distance but rather in durability and control and even customizing for specific swing speeds.
 
This was not the case when we used wound balls but those days are long gone. If you are talking abut wound balls then the modern multi-layered balls have already done you in. Even though the wound balls will deteriorate slower than the new balls the technology has already made these balls obsolete.
 
Frank,
With all the hybrids being used these days, why don't major manufactures and component suppliers alike stop offering 3-pw sets and start offering 5-GW sets with the option of hybrids or 3/4 iron, just like a SW or LW that they do now. - Tom Matthews

 
Tom,
The main reason is that they have not truly come to terms with the change in set make up and also that they can sell more clubs. A full set, as we knew it -- 2-PW& SW, is now obsolete. If you have to buy this set you need to dump at least three clubs (2- 3- & 4- irons) and replace these with two hybrids and a Gap wedge. Then if you decide you need some more control around the greens with a Lob wedge you may have to dump your 5-wood.
 
Things will soon change as the set make up will adjust to the trends and those manufacturers who do not shift will not get the business.

Stock Watch: Lexi, Justin rose or fall this week?

By Ryan LavnerNovember 21, 2017, 2:36 pm

Each week on GolfChannel.com, we’ll examine which players’ stocks and trends are rising and falling in the world of golf.

RISING

Jon Rahm (+9%): Just imagine how good he’ll be in the next few years, when he isn’t playing all of these courses for the first time. With no weaknesses in his game, he’s poised for an even bigger 2018.

Austin Cook (+7%): From Monday qualifiers to Q-School to close calls on the Web.com, it hasn’t been an easy road to the big leagues. Well, he would have fooled us, because it looked awfully easy as the rookie cruised to a win in just his 14th Tour start.

Ariya (+6%): Her physical tools are as impressive as any on the LPGA, and if she can shore up her mental game – she crumbled upon reaching world No. 1 – then she’ll become the world-beater we always believed she could be.  

Tommy Fleetwood (+4%): He ran out of gas in Dubai, but no one played better on the European Tour this year than Fleetwood, Europe’s new No. 1, who has risen from 99th to 18th in the world.   

Lexi (+1%): She has one million reasons to be pleased with her performance this year … but golf fans are more likely to remember the six runners-up and two careless mistakes (sloppy marking at the ANA and then a yippy 2-footer in the season finale) that cost her a truly spectacular season.


FALLING

J-Rose (-1%): Another high finish in Dubai, but his back-nine 38, after surging into the lead, was shocking. It cost him not just the tournament title, but also the season-long race.  

Hideki (-2%): After getting blown out at the Dunlop Phoenix, he made headlines by saying there’s a “huge gap” between he and winner Brooks Koepka. Maybe something was lost in translation, but Matsuyama being too hard on himself has been a familiar storyline the second half of the year. For his sake, here’s hoping he loosens up.

Golf-ball showdown (-3%): Recent comments by big-name stars and Mike Davis’ latest salvo about the need for a reduced-flight ball could set up a nasty battle between golf’s governing bodies and manufacturers.

DL3 (-4%): Boy, the 53-year-old is getting a little too good at rehab – in recent years, he has overcome a neck fusion, foot injury, broken collarbone and displaced thumb. Up next is hip-replacement surgery.

LPGA Player of the Year (-5%): Sung Hyun Park and So Yeon Ryu tied for the LPGA’s biggest prize, with 162 points. How is there not a tiebreaker in place, whether it’s scoring average or best major performance? Talk about a buzzkill.

Titleist's Uihlein fires back at Davis over distance

By Golf Channel DigitalNovember 21, 2017, 12:59 am

Consider Titleist CEO Wally Uihlein unmoved by Mike Davis' comments about the evolution of the golf ball – and unhappy.

In a letter to the Wall Street Journal, the outlet which first published Davis' comments on Sunday, Uihlein took aim at the idea that golf ball distance gains are hurting the sport by providing an additional financial burden to courses.

"Is there any evidence to support this canard … the trickle-down cost argument?” he wrote (via Golf.com). “Where is the evidence to support the argument that golf course operating costs nationwide are being escalated due to advances in equipment technology?"

Pointing the blame elsewhere, Uihlein criticized the choices and motivations of modern architects.

"The only people that seem to be grappling with advances in technology and physical fitness are the short-sighted golf course developers and the supporting golf course architectural community who built too many golf courses where the notion of a 'championship golf course' was brought on line primarily to sell real estate," he wrote.

The Titleist CEO even went as far as to suggest that Tiger Woods' recent comments that "we need to do something about the golf ball" were motivated by the business interersts of Woods' ball sponsor, Bridgestone.

"Given Bridgestone’s very small worldwide market share and paltry presence in professional golf, it would seem logical they would have a commercial motive making the case for a reduced distance golf ball," he added.

Acushnet Holdings, Titleist's parent company, announced in September that Uihlein would be stepping down as the company's CEO at the end of this year but that he will remain on the company's board of directors.

Class of 2011: The groups before The Group

By Mercer BaggsNovember 20, 2017, 9:00 pm

We’ve been grouping things since the beginning, as in The Beginning, when God said this is heaven and this is earth, and you’re fish and you’re fowl.

God probably wasn’t concerned with marketing strategies at the time and how #beastsoftheearth would look with a hashtag, but humans have evolved into such thinking (or not evolved, depending on your thinking).

We now have all manner of items lumped into the cute, the catchy and the kitschy. Anything that will capture our attention before the next thing quickly wrests said attention away.

Modern focus, in a group sense in the golf world, is on the Class of 2011. This isn’t an arbitrary assembly of players based on world ranking or current form. It’s not a Big Pick A Number.

There’s an actual tie that binds as it takes a specific distinction to be part of the club. It’s a group of 20-somethings who graduated from high school in the aforementioned year, many who have a PGA Tour card, a handful of who have PGA Tour wins, and a couple of who have major titles.

It’s a deep and talented collective, one for which our knowledge should continue to expand as resumes grow.

Do any “classes” in golf history compare? Well, it’s not like we’ve long been lumping successful players together based on when they completed their primary education. But there are other notable groups of players, based primarily on birthdate, relative competition and accomplishment.

Here’s a few on both the men’s and women’s side:

BORN IN 1912

Birthdate Player PGA Tour wins Major wins
Feb. 4, 1912 Byron Nelson 52 5
May 27, 1912 Sam Snead 82 7
Aug. 13, 1912 Ben Hogan 64 9

Born six months within one another. Only a threesome, but a Hall of Fame trio that combined for 198 PGA Tour wins and 21 majors.


BORN IN 1949

Birthdate Player PGA Tour wins Major wins
Sept. 4, 1949 Tom Watson 39 8
Dec. 5, 1949 Lanny Wadkins 21 1
Dec. 9, 1949 Tom Kite 19 1

Only 96 days separate these three Hall of Fame players. Extend the reach into March of 1950 and you'll get two-time U.S. Open winner Andy North.


BORN IN 1955

Birthdate Player PGA Tour wins Major wins
Jan. 30, 1955 Curtis Strange 17 2
Jan. 30, 1955 Payne Stewart 11 3
Feb. 10, 1955 Greg Norman 20 2

Another trio of Hall of Fame players. Strange and Stewart were born on the same day with Norman 11 days later. Fellow PGA Tour winners born in 1955: Scott Simpson, Scott Hoch and Loren Roberts.


WITHIN A CALENDAR YEAR, 1956-57

Birthdate Player LPGA wins Major wins
Feb. 22, 1956 Amy Alcott 29 5
Oct. 14, 1956 Beth Daniel 33 1
Oct. 27, 1956 Patty Sheehan 35 6
Jan. 6, 1957 Nancy Lopez 48 3

A little arbitrary here, but go with it. Four Hall of Famers on the women's side, all born within one year of each other. That's an average (!) career of 36 tour wins and nearly four majors.


EUROPE'S BIG 5

Birthdate Player Euro (PGA Tour) wins Major wins
April 9, 1957 Seve Ballesteros 50 (9) 5
July 18, 1957 Nick Faldo 30 (9) 6
Aug. 27, 1957 Bernhard Langer 42 (3) 2
Feb. 9, 1958 Sandy Lyle 18 (6) 2
March 2, 1958 Ian Woosnam 29 (2) 1

The best 'class' of players Europe has to offer. Five born within a year of one another. Five Hall of Fame members. Five who transformed and globalized European golf.


WITHIN A CALENDAR YEAR, 1969-70

Birthdate Player PGA Tour wins Major wins
Sept. 12, 1969 Angel Cabrera 3 2
Oct. 17, 1969 Ernie Els 19 4
May 12, 1970 Jim Furyk 17 1
May 12, 1970 Mike Weir 8 1
June 16, 1970 Phil Mickelson 42 5

Not a tight-knit group, but a little more global bonding in accordance to the PGA Tour's increased international reach. Add in worldwide wins – in excess of 200 combined – and this group is even more impressive.


BORN IN 1980

Birthdate Player PGA Tour wins Major wins
Jan. 9, 1980 Sergio Garcia 10 1
July 16, 1980 Adam Scott 13 1
July 30, 1980 Justin Rose 8 1

Could be three future Hall of Fame members here.
