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.
Totally agree. There is an art to green reading that is getting lost, just like judging the wind & this will help speed up play ???????? https://t.co/epWiq1jUOC

I’m going to gush in this intro paragraph, to get the emo stuff done early. I’ve not pulled harder for a professional to win, than Cameron Young. I coach golf in New York state, and each spring, my best golfers head to a state championship in Poughkeepsie. I first saw Cameron there as a 9th grade student. I saw him three more times after that. I reconnecected with Coach Haas from Wake Forest, an old interview subject from my days on the Old Gold and Black, the Wake newspaper. He was there to watch Cameron. After four years at Wake Forest, Young won on the Korn Ferry Tour, made it to the big tour, almost won two majors, almost won five other events, and finally got the chalice about 25 minutes from the Wake campus. Congratulations, Cameron. You truly are a glass of the finest. #MotherSoDear
OK, let’s move on to the Tour Rundown. The major championship season closed this week in Wales, with the Women’s Open championship. The PGA Tour bounced through Greensboror, N.C., while the PGA Tour Americas hit TO (aka, Toronto) for a long-winded event. The Korn Ferry lads made a stop in Utah, one of just two events for that tour in August. The many-events, golf season is winding down, as we ease from summer toward fall in the northern hemisphere. Let’s bask in the glory of an August sunrise, and run down a quartet of events from the first weekend of the eighth month.
LET/LPGA @ Women’s Open: Miyu bends, but she doesn’t break
Royal Porthcawl was not a known commodity in the major tournament community. The Welsh links had served as host to men’s senior opens, men’s amateurs, and Curtis and Walker Cups in prior years, but never an Open championship for the women or the men. The last-kept secret in UK golf was revealed once again to the world this week, as the best female golfers took to the sandy stage.
Mao Saigo, Grace Kim, Maja Stark, and Minjee Lee hoped to add a second major title to previous wins this season, but only Lee was able to finish inside the top ten. The 2025 playing of the Women’s Open gave us a new-faces gallery from day one. The Kordas and Thitikulls were nowhere to be found, and it was the Mayashitas, Katsus, and Lim Kims that secured the Cymru spotlight. The first round lead was held at 67 by two golfers. One of them battled to the end, while the other posted 81 on day two, and missed the cut. Sitting one shot behind was Miyu Yamashita.
On day two, Yamashita posted the round of the tournament. Her 65 moved her to the front of the aisle, in just her fourth turn around a women’s Open championship. With the pre-event favorites drifting off pace, followers narrowed into two camps: those on the side of an underdog, and others hoping for a weekend charge from back in the pack. In the end, we had a bit of both.
On Saturday, Yamashita bent with 74 on Saturday, offering rays of hope to her pursuing pack. England’s Charley Hull made a run on Sunday closing within one shot before tailing off to a T2 finish with Minami Katsu. Katsu posted the other 65 of the week, on Saturday, but could not overtake her countrywoman, Yamashita. wunderkind Lottie Woad needed one round in the 60s to find her pace, but could only must close-to’s, ending on 284 and a tie with Minjee for eighth.
On Sunday, Yamashita put away the thoughts of Saturday’s struggles, with three-under 33 on the outward half. She closed in plus-one 37, but still won by two, for a first Major and LPGA title.
PGA Tour @ Wyndham: Young gathers first title near home
Cameron Young grew up along the Hudson river, above metro New York, but he also calls Winston-Salem home. He spent four years as a student and athlete at Wake Forest University, then embarked on tour. This week in Greensboro, after a bit of a break, Young opened with 63-62, and revved the engine of Is this the week once more. Runner-up finishes at the Open, the PGA, and a handful of PGA Tour events had followers wonder when the day would come.
On Saturday, Young continued his torrid pace with 65, giving him a five-shot advantage over his closest pursuer. Sunday saw the Scarborough native open with bogey, then reel off five consecutive birdies to remind folks that his time had, at last, arrived. Pars to the 16th, before two harmless bogeys coming home, made Young the 1000th winner of an official PGA Tour event (dating back to before there was a PGA Tour) throughout history. What’s next? I have a suspicion, but I’m not letting on. Mac Meissner closed with 66 to finish solo 2nd, while Mark Hubbard and Alex Noren tied for third.
Korn Ferry Tour @ Utah Championship: Are you Suri it’s Julian?
Who knows exactly when the flower will bloom? Julian Suri played a solid careet at Duke University, then paid his dues on the world’s minor tours for three years. He won twice on two tours in Europe, in 2017. Since then, the grind has continued for the journeyman from New York city. At age 34, Suri broke through in Beehive state, outlasting another grinder (Spencer Levin) and four others, by two shots.
Taylor Montgomery began the week with 62, then posted 64, then 68, and finally, 70. That final round was his undoing. He finished in that second-place tie, two back of the leader. Trace Crowe, Barend Botha, and Kensei Hirata made up the last of the almost quintet. As for Suri, his Sunday play was sublime. His nines were 32 and 31, with his only radar blip a bogey at ten. He closed in style with one final birdie, to double his winning margin. Hogan bloomed late…might Suri?
PGA Tour Americas @ Osprey Valley Open presented by Votorantim Cimentos – CBM Aggregates
Some tournament names run longer than others. This week in Toronto, at the Heathlands course at TPC Toronto, we might have seen the longest tournament title in recorded history. The OVOPBVCCBMA was a splendid affair. It saw three rounds of 62 on Thursday, but of those early risers, only Drew Goodman would stick around until the end. 64 was the low tally on day two, and two of those legionnaires managed to finish inside the top three at week’s end. Saturday brought a 63 from Patrick Newcomb, and he would follow with 64 on Sunday, to finish solo fourth.
Who, then, ended up winning the acronym of the year? It turns out that Carson Bacha had the right stuff in TeeOhhh. Bacha and Jay Card III posted 63 and 64, respectively, on day four, to tie for medalist honors at 23-under 261. Nathan Franks was one shot adrift, despite also closing with 63. If you didn’t go low on Sunday, it was about the check, not the championship.
Bacha and JC3 returned to the 18th hole twice in overtime. Card nearly chipped in from the thick stuff for birdie, while Bacha peeked and shoved a ten-feet attempt at the win. On the second go-round, Card was long with his approach, into the native grasses once more. He was unable to escape, and a routine par from the fairway was enough to earn the former Auburn golfers a first KFT title.
Card III and Bacha both miss their birdie tries on the first playoff hole.

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

May 30, 2017 at 2:25 am
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

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.
Dace
May 3, 2017 at 11:53 am
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 .
Bob Jones
May 3, 2017 at 11:39 am
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.
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.
JLBIII
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.
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.
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 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!
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.
avg_joseph
May 2, 2017 at 5:14 pm
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 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.

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?
RG

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.
Pathetic…..

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.

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.
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?
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.
