The USGA might have a problem with PGA Tour yardage books



Less than a week after introducing the “Lexi Thompson Rule,” or New Decision 34-3/10, the USGA sent a signal that it has something else on its radar. Namely, defending the art of green reading.

Viewing the issue through the lens of Rule 14-3, the USGA expressed concern over, it seems, the green detail in professional yardage books. Rule 14-3 bars a player from “the use of any artificial device or unusual equipment … for the purpose of gauging or measuring distance or conditions that might affect his play.” Thus, in a roundabout way, the green-mapping technology used to create the highly sophisticated and detailed pro yardage books is troubling to the guardians of the game.

The USGA-R&A’s full joint statement reads:

“The R&A and the USGA believe that a player’s ability to read greens is an essential part of the skill of putting. Rule 14-3 limits the use of equipment and devices that might assist a player in their play, based on the principle that golf is a challenging game in which success should depend on the judgment, skills and abilities of the player. We are concerned about the rapid development of increasingly detailed materials that players are using to help with reading greens during a round. We are reviewing the use of these materials to assess whether any actions need to be taken to protect this important part of the game. We expect to address this matter further in the coming months.”

Reading between the lines, it certainly seems the “concern” is centered around yardage books that show slope and topographical information. You know, like these.

Thomas Pagel, the USGA’s senior director of rules and amateur status, told Golf Digest’s Mike Stachura the worry centers around the following:

“The increased level of detail that the USGA and the R&A has seen of late, both in printed and electronic form, that has prompted the study. It is fair to say all materials will be reviewed, but the original intent was not focused on basic printed yardage guides found at most golf courses, but those with an increased level of detail/sophistication.”

This led Stachura to connect the dots, writing, “It seems conceivable that green charts instead of contour lines measuring the percentage of slope…might someday reach a stage where all putting locations might be determined to have a certain break like two feet right or six inches left.”

Yardage books in general have long been contentious on the PGA Tour, but the USGA largely hasn’t had an issue with the pocket course maps until now. It will be interesting to see if the folks in Far Hills ultimately rule on the level of detail in Mark Long’s (and similar) yardage books.

If you ask PGA Tour pro Luke Donald, he seems to agree with the concern.

    Give them lasers for yardage use only. let them carry there own bags read there own greens. Spoilt children these pros are.

    So, here’s a question… if the USGA generally allow rangefinders that don’t allow slope, how is it they’re being provided with slope information? How has that been allowed to become a cottage industry?

    Personally, I think this is all a waste. I think the slope algorithm in the current rangefinders aren’t a big deal. Frankly, whatever speeds play is good, and those books don’t sink putts. But this type of grandstanding just annoys players. But please start making the pros play like we have to. Let them have a laser, but take their books. Or don’t, and clarify that slope information is ok. What drives me batty about the USGA is they approach it as if it’s this new thing. It’s not.

    Personally I think you would have to have studies in rocket science to even read this thing. I would not know which way to turn the thing up down or sideways. But then I never went far in college never got to map reading.

    The game has gotten too concerned with low scores and records. We also should go back to not allowing to mark the ball on the green and play stymie. It’s about who navigates the situations to win the tournament, not about just getting low scores

    • PG

      Stymie is awesome for match play. It would be fun to watch. During stroke play it could be abused and would be unfortunate if it affected the outcome.

    I would like to see this stopped.
    Along with that I would also like to see caddies actually just caddy.
    Carry the bag, give distance from the ball to the pin and little else.
    Keep them off the greens and lets see the pros use their own skills to navigate the contours.
    Simplify the rules also, ball on tee not to be touched again until it is on the green.
    Any unplayable/lost/hazard ball, drop at the original point of strike with a shot penalty.
    Remove all line of sight relief.
    As mentioned above remove all grandstands from the green area.
    Also in agreement with Brandon … Brandon May 3, 2017 at 10:05 am

    Actually I would like to see a 90 second shot clock with 3 60 second extensions per round, but that is me personally.

    The game is too slow and the rules too complex.
    We are losing a generation to the game, almost no one understands the rules now .

    Why not go all the way and make the pros play like the rest of us do? Ban yardage books (except for notes they personally make during practice rounds), ban daily pin sheets, ban caddies. Make them pull their clubs around on a cart and hunt for sprinkler heads to get their distances. Really! I’m not kidding. Once a year I would like to see a tournament played like this.

  8. Duncan Castles

    May 3, 2017 at 9:30 am

    Fully agree that the governing bodies should ban the use of detailed green charts during competitive rounds. They both slow down the game and reduce the need to develop and deploy one of golf’s key skills.


    May 3, 2017 at 8:35 am

    For the last 15 years, I’ve used my feet to read greens. I would never use a mapped chart because it would change my trust and confidence in what I feel.

  10. Ron

    May 3, 2017 at 8:29 am

    Good idea! Caddies should also not be able to give players any information other than distances and wind direction. The player ought to be able to figure out what club to hit and how to hit it. That goes for alignment too.
    And, USGA, address the ball in motion rule, where the wind moves the ball on the green. The player who doesn’t cause the ball to move should be able to replace it in its original spot without penalty.

  11. Jack Nash

    May 3, 2017 at 8:05 am

    Great idea. Let’s make a 6 hr round 6 1/2 while watching a pro do laps on a green before they decide to get over the ball. Next thing you know there’ll be a 24 sec. clock.

    I’m curious who and what kind of tech creates these topographical green maps? Must be already in the yardage books given to the players before the tournament.

  13. Gordy

    May 2, 2017 at 8:48 pm

    I wish they’d ban the grand stands behind every green that stops the ball from going 30 yards past the hole on a bad shot.

    • Adam P Smith

      May 3, 2017 at 8:54 am

      Agree 100%. In fact last week in China at the European Tour event the 18th hole had water cutting in to the green on the right side with the flag (for round 4) inaccessible some 6 paces from the water. Immediately left of the green was a stand, the closest to a green I’ve ever seen. What happens? More than one pro took dead aim at the lower portion of this stand from 150-180 yards away and bounced the ball onto the green and close to the flag; closer than could have been achieved by a normal shot. Utter madness on the part of the tournament director and officials…those guys need sacked. It’s golf not billiards!

  14. larrybud

    May 2, 2017 at 6:24 pm

    Yeah, I can see how this is a problem since nobody seems to miss any putts…. lol I mean, who cares? You better ban all yardage books then, and sprinkler heads with numbers on them, since those numbers were derived from laser range finders.

    Stupid is as stupid does, sums up the USGA nicely.

    If all players have access to this same information what does it matter? If the information is out their and they are banned during tournament play, all you are doing is giving a leg up to players with better memory/photographic memory…

    Access to this information speeds up play as well. Do you really want to have these guys(and gals) with millions of dollars on the line taking longer to read putts on their own? If pace of play is such an important issue to the USGA why would they take detailed information out of a players hand that is going to make the pros take longer to do their job? If anything, Courses that have this information should give these to any player with the knowledge to use them to help speed up play!

    • Adam P Smith

      May 3, 2017 at 8:57 am

      Nonsense, use of these green-reading books slows play down; are you Stevie Wonder? But slow play isn’t the real issue in this: skill and judgment is what golf is founded upon not having fancy, cheat-bibles like these.

      I don’t see a problem either, nobody has an advantage over one another with these technological breakthroughs, and it results in better quality golf

  17. Taylor

    May 2, 2017 at 1:42 pm

    I thought the yardage books just had blank green shapes and the pros filled them out as they read the greens. The advantage to the more veteran guys whom have played the greens more and have had many different looks. I didn’t know they were given how the topography of the greens were.

  18. Mark

    May 2, 2017 at 1:29 pm

    Good grief. I had no idea they were that detailed. Let us get back to the player and only the player lining up his putts. And these maps should be banned. The club player uses his own eyes so why not someone supposedly more skilled?

  19. ROY

    May 2, 2017 at 9:40 am

    So if I can bring a topographical map why not a wind gauge?? Could extend my 18 foot ball retriever, stick it on the top of that and be a little more certain about what the winds speed and direction is.

    • John

    May 2, 2017 at 9:33 am

    I believe the charts get even more complicated/detailed than what is pictured.

    And I think they should be restricted at some point. Laser rangefinders that calculate slope are banned from tournament use. What’s the basic difference between that and a fold-out chart that details every little slope in the green?

  21. RG

    May 2, 2017 at 7:03 am

    More ridiculousness from the USGA. Graphite shafts, titanium golf clubs, range finders and four piece multi material golf balls are good, topographical maps bad! ridiculous! the toothpaste is out of the tube.

    Seriously USGA….

    This is completely ridiculous. These guys talk about growing the game but yet have zero clue as to what it takes to actually pulls off what current PGA tour pros do. Its actually a little disgusting that these dinosaurs are guiding a sport that so desperately needs an injection of life.

    This still comes down to execution. You HAVE to be able to execute exactly what it says on the books, whether its yardage or the slopes on a green.


    • Brian

      What does the use of detailed topographical maps by Tour Pros have to do with growing the game?

        My question, as well. The two are not related in the slightest.

      ya dumb response, nobody else has access to these charts and even if they did talk about slowing the F out of the game….I can’t stand the USGA but 100% agree with this concern. Putting at all levels is fun to be a part of and the art of the “guess” is great at all levels……

    • Judge Smells

      May 2, 2017 at 12:03 pm

      cant wait till you see kids at Junior tournaments making topographically maps of the green during their practice round so they can be like Dustin Johnson referring to their green map

  24. DMACK

    May 1, 2017 at 9:43 pm

    I have been playing the same courses for years and am still trying to figure out and remember all the breaks. I definitely think green reading is a big part of the art of putting. The green contour map like shown above can be viewed as equipment that aides the golfer. It’s at least worth a debate. (Can I order such a map for my home course, surely could eliminate some 3 putts.)

    • Scott

      May 2, 2017 at 7:57 am

      DMACK, I was told by a guy at Golf Galaxy that there are highly detailed yardage books out there now (or on their way), but I was told they are a bit pricey. Might be worth it for a few courses though.

    • Zach

  25. Daniel

    May 1, 2017 at 6:53 pm

    If reading a green is an integral part of the game to be preserved where does that leave us with rangefinders? If judgement of a putt is a skill to be preserved and rewarded why not yardage estimation?

    But, I don’t need a thing to make the game harder and I’d wager the bulk of golfers don’t either. Furthers the argument that rules bifurcation is needed in some degree.

    • H

      May 2, 2017 at 3:06 am

      You can’t use rangefinders in professional competition. So that’s what this is implying, that perhaps during play, these contour-Aimpoint maps will be banned, only to be used during practice rounds, as the rangefinders are.

  26. Adam

    May 1, 2017 at 6:40 pm

    I assume, then, that these things are why pros look COMPLETELY AND UTTERLY BEWILDERED when they miss something inside 10 feet? They look at these sheets, it tells them one things, they go with it, they miss, they curse the world. How much reliance is on these books and how much of it is actual green reading?

  27. Double Mocha Man

    May 1, 2017 at 4:45 pm

    It is an interesting sort of “give an inch, take a foot” quandary for the USGA. A topographic map for backpacking is good, a topographic map for reading greens is cheating. Unless you’re camping out on the steep ridge on #14 green at Pebble Beach.

    seems like luke donald needs to heed some advice from Kendrick Lamar – sit down, be humble.

    wow, players doing what they can while adhering to the rules to help gain information about a course? crazy talk. USGA, stop screwing things up every chance you get. Let your DVR-committee do your bidding to get your rulings right. USGA puts out that they want to allow rangefinders or measuring devices but want to dial back the information you can put in your yardage book? smh.

    • TR1PTIK

      May 1, 2017 at 5:08 pm

      I don’t think their issue is necessarily the level of detail within a yardage book as much as it is how that information is obtained. However, you could not achieve the same level of detail by simply walking a green and rolling a few putts. I agree with the USGA and with Luke Donald though. Green reading is an acquired skill and a bit of an art. Players should be allowed to record slope information in their yardage book, but without the assistance of special equipment. They should only be allowed to make note of the things they can visibly see and physically feel. They should not be able to use any type of technology to help them measure the various contours of a green. Plain and simple. And no, I don’t believe this is in any way similar to using a rangefinder that ONLY measures yardage. Yardage is a far easier measurement to obtain through other means and I believe the use of rangefinders can only help pace of play.

      • Kim

        May 2, 2017 at 10:59 am

        These contour maps are made by digital mapping of the greens. It would be impossible to enforce a rule banning the maps as players could review in privacy off the course. They should be banned on the course during play, including practice and tournament rounds.

        • TR1PTIK

          May 2, 2017 at 1:51 pm

          I think that kind of goes without saying which is why it wasn’t said. Lol. Anyone can do whatever they want off the course.

10 interesting photos from Tuesday at the Zurich Classic



GolfWRX is live from the 2018 Zurich Classic at TPC Louisiana, where, among other things, a giant three-legged crocodile roams.

Now in it’s second year, the tournament’s unique two-man team format has attracted a wealth of top talent, including 10 of the top 14 golfers in the OWGR. We’re on the scene snapping bag pictures and have five galleries from TPC Louisiana’s range Tuesday. We also have a look inside Ryan Ruffels bag, a peek at Jimmy Walker’s putter, a look in Brooks Koepka’s bag, and more!

Let’s dig in.

Well, this certainly is interesting, Xinjun Zhang. Not sure about the context, but not something you traditionally see on a PGA Tour driving range…

Hard not to love Ryan Ruffels’ 009M

Look’s like Michael Greller is enjoying some well-earned relaxation

Ryan Palmer boldly going where few Tour pros dare to: serif font

Roman numeral loft stamping? Savage grind? We like your style, Bud Cauley

Is this a new Wilson Staff PMP wedge prototype or a one-off thing for Ricky Barnes?

Finally, Whitney comes to a wedge

Detroit could be getting a PGA Tour event



As a business based in the Detroit metro area, GolfWRX is happy to hear this: the Motor City could be getting a PGA Tour event.

With the PGA Tour’s 2019-2020 schedule expected in the weeks ahead, the Detroit News reports the Tour could announce (Detroit-based) Quicken Loans will sponsor an event at Detroit Golf Club. The company ceased sponsorship of the former Quicken Loans National in Washington, D.C. last year.

The Detroit News quotes a source with knowledge of the Tour’s scheduling discussions as saying an official announcement is near.

While the Tour, Quicken Loans, and Detroit Golf Club are mum on the matter, Quicken Loans’ statement to the paper last year made clear the company’s intention to bring a tournament to the city.

“As we look to the future, we remain interested in exploring ways to highlight the energy and revitalization taking place in Detroit…A prime golf event, featuring the world’s best players, is certainly something we would be interested in pursuing as a way to showcase our great American city.”

If the Detroit tournament takes the calendar spot of the The National, it would be contested in late June/early July. Additionally, with the PGA Championship’s move to may next year, there’s some speculation the Detroit event could be contested in August.

As mentioned, we know the PGA Championship is moving to May in 2019. Additionally, The Players will move to March, TPC Southwind will take over  WGC hosting duties from Firestone Country Club, and the FedEx Cup Playoffs will wrap before start of football season.

We’ll have to wait (eagerly) for official word on the Detroit event.

Tuesday’s Photos from the 2018 Zurich Classic



GolfWRX is live from the 2018 Zurich Classic at TPC Louisiana (par 72; 7,425 yards), designed by Pete Dye with consultants Steve Elkington and Kelly Gibson.

The Zurich Classic is a unique event on the PGA Tour because it’s not an individual stroke-play event. Instead, the format consists of two-man teams playing best-ball on Thursday and Saturday, and alternate-shot on Friday and Sunday.


Last year, Cameron Smith and Jonas Blixt won the event after four playoff holes against Kevin Kisner and Scott Brown. The Smith/Blixt duo will be back to defend their title, and the Kisner/Brown pairing will be back avenging their loss.

Other notable pairings in the field include Daniel Berger/Gary Woodland, Wesley Bryan/Jon Rahm, Patrick Reed/Patrick Cantlay, John Daly/Rory Sabbatini, Jason Day/Ryan Ruffels, David Duval/Jim Furyk, Tony Finau/Daniel Summerhays, Sergio Garcia/Rafa Cabrera Bello, J.B. Holmes/Brand Snedeker, Matt Kuchar/Bubba Watson, Louis Oosthuizen/Charl Schwartzel, Sean O’Hair/Jimmy Walker, Pat Perez/Jason Dufner, Justin Rose/Henrik Stenson, Jordan Spieth/Ryan Palmer, Justin Thomas/Bud Cauley and more!
