There has been a LOT of discussion lately about single-length iron sets. So much, in fact, that as a club builder and fitter single-length irons have become a daily topic of conversation.
Most of this buzz about single-length irons has been created by reigning U.S Amateur and NCAA Division I Individual champion Bryson DeChambeau, who has been very successful using a custom set of single-length irons made by Edel, a boutique equipment company in Texas.

Edel isn’t the first company to build a set of single-length irons. Tommy Armour built and marketed a set called the EQL’s in the 80’s, and there have been a few other niche companies who have been building these sets for a long time, including One Iron Golf. Recently, Tom Wishon and Jaacob Bowden released a set of single-length irons. Named Sterling Irons, they’re designed to be built shorter than others. At 36.5 inches, they’re each about the length of an 8-iron.

All of the sets listed above have one thing in common; they were designed with the sole purpose of being built to a single length. With this trend gaining more interest from the general golfing public the most popular questions are:
- Can single length irons work for me?
- Can I make my current set into a single-length set?
I’m going to explain the differences between a standard set of irons and single-length irons, why it’s difficult to convert a standard set of irons to single length and what is needed to make sure proper gapping is achieved throughout the set.
According to DeChambeau and the team at Edel, his set took many attempts to get just right. And as a club builder who is getting requests for this type of set, it’s difficult to explain the small nuances involved to golfers, especially those players looking to do this to either an existing set or to a new one built from scratch using standard OEM components. It’s also difficult to fit a golfer for this type of set because of the cost associated with having enough club heads of varying lofts to properly fit for distance gapping.
The other piece of information that I don’t believe has been mentioned enough as it pertains to the average golfer is that DeChambeau is a finely tuned athlete who swings his 45-inch driver at more than 120 mph. Most club players can only swing that fast in their dreams, and DeChambeau’s speed gives him a distinct advantage with his irons.
If you give a golfer five clubs of the same length, shaft flex, total weight, and swing weight, they will swing them at almost exactly the same speed. Give that golfer a traditional set of irons that are built with shafts that get approximately 0.5-inches longer as the iron number decreases (with the same shaft, shaft flex, swing weight and a decreasing head weight of 7-to-10 grams per club), however, and they will likely swing each club 2-3 mph faster as they move up the set.
The increased clubhead speed translates into faster ball speeds in the longer irons, which is needed to maintain a consistent peak height from the lower-lofted clubs, also know as a consistent flight window. Smash Factor also slowly increases, because the reduced loft will transfer more energy into the ball (the contact is less “glancing” or oblique), creating faster ball speeds with the longer clubs.
Distance gapping can become an issue in the longer clubs with a single-length iron set, because swing speed does not stay the same as loft is reduced. That’s why DeChambeau’s custom Edel set uses bigger loft gaps (5 degrees) in the longer clubs. Wishon’s Sterling irons do not have this design, but he addressed the issue by making the faces of his long irons “hotter,” which has the same effect.
Here is where things become very difficult from a building perspective. Standard head weights for irons are not designed to be built to the same length. They are engineered for a company’s specific length progression, generally 0.5 inches between clubs.
The chart below demonstrates the difference in club head mass between standard head weights of a set built to roughly D3 and a set of single-length irons.
DeChambeau plays his entire set at 73-degree lie angle, which is more upright than the lie angle of most off-the-rack putters! Trying to bend a set of standard iron heads to these angles would either totally mar the hosels or cause them to break, especially considering many irons now are made of multiple materials and advanced constructions. DeChambeau’s Edel irons, on the other hand, are forged and more easily bent.
It should also be noted that DeChambeau’s irons are manufactured so there is no negative effect on performance. And his extremely upright lie angles are the result of his unique swing mechanics, and are not necessary to use a single-length iron set.
The chart below demonstrates standard lie angles vs. DeChambeau’s Clubs.
Going back to the issue of gapping, with a set of single-length clubs, lofts need to be adjusted accordingly to make sure that golfers have proper yardage gaps between clubs. With any player, the gapping will depending on swing speed.
The Trackman data below shows some interesting information based my testing a set of single-length irons (37.5 inches) and a set of irons built to standard lengths with frequency matched shafts, matching swing weights, and built in 0.5-inch increments.
The conclusion is that single-length irons might be the perfect solution to creating more consistency in your golf game, but just like buying a new driver or standard set of irons, be sure to visit a proper club fitter. It will take some time to find the right components to fit your needs.

Vincenzi: How the 2022 Presidents Cup actually grew the game
As fall approached, the world of professional golf was drowning in a sea of continuous division and animosity.
The Presidents Cup, which should have been a silver lining in the most tumultuous time in the history of the sport, had suddenly become a pasquinade.
The Internationals had always been an underdog and had just one win in fourteen tries against the Americans.
In 2019, the scrappy Internationals led by Ernie Els gave the United States team led by Tiger Woods all that they could handle at Royal Melbourne. The United States retained the cup, winning the competition 16–14, but the Els’ team fought to the end. The future was bright for professional golf on the world stage.
In 2022, things were different. The Internationals had just lost arguably their two best players in Cameron Smith and Joaquin Niemann, plus a handful of other Presidents Cup shoe-ins including Louis Oosthuizen and Abraham Ancer.
The International players who had joined the controversial LIV Golf series were deemed ineligible to participate in the competition, which resulted in the decimation of what should have been a deep and competitive team of Internationals. By the time the event started, the United States had ballooned to a -900 favorite.
One phrase that’s been repeated ad nauseum over the past few months has been “grow the game”.
After a bleak opening few days at the Presidents Cup, we caught a glimpse of what “growing the game” looked like over the weekend.
There are plenty of ways to potentially grow the game of golf. One of those ways unfolded in real time at Quail Hollow thanks in part to a spirited group of Asian golfers who refused to let their team go quietly into the night.
First, there was the budding superstar, Tom Kim.
Kim scored two points for the Internationals, but the impact he had on the event dwarfed his point total. The South Korean hijacked the event with his charisma, energy and determination to help his team succeed. Golf fans were treated to memorable moment after memorable moment whenever the 20-year-old was on their television screen.
Kim had already had a handful of moments that will live in our memories for many Presidents Cups to come, but the most memorable came on the 18th hole of Saturday’s afternoon foursomes. Facing a seemingly invincible duo of Patrick Cantlay and Xander Schauffele, Kim put a 2-iron to less than six feet of the hole. He then sunk the clutch putt to knock off the fourth and fifth ranked players in the world.
TOM KIM FOR THE WIN!!!
— Presidents Cup International Team (@IntlTeam) September 24, 2022
Tom wasn’t the only “Kim” to leave a lasting impact at the 2022 Presidents Cup. Fellow South Korean Si Woo Kim had his share of memorable moments as well.
Going into Sunday singles, the Internationals were trailing 11-7 and in need of a historic day. Typically, the trailing team will “frontload” their best players to attempt a comeback. When United States captain Davis Love III called the name of Justin Thomas to lead off in the first match of the day, many expected the international team captain Trevor Immelmann to call the name of Hideki Matsuyama or Adam Scott. Instead, he called the name of Si Woo Kim.
Si Woo did not disappoint. Kim took out the de-facto leader of the United States team 1-up. The 27-year-old didn’t shy away from the spotlight, and matched Thomas both in his ability to sink clutch putts and to bring energy with his animated style of play.

Tom Kim and Si Woo Kim provided some of the most memorable moments of the Presidents Cup, but it’s Sungjae Im who’s been the best player for the Internationals in both 2019 and 2022.
Back in 2019, Sungjae tied with Abraham Ancer for the leading points scorer (3.5) for the Internationals during their narrow defeat in Australia. He was a rookie then, but this year he was depended upon to go against some on the United States best teams and delivered, scoring 2.5 points and knocking off young American star Cameron Young in their singles match.

As influential as the performances by the trio of South Koreans were, the overall impact of Asian golfers cannot be discussed without mentioning Hideki Matsuyama.
The 2021 Masters Champion has long been rumored to be interested in joining LIV Golf, but he was at Quail Hollow competing alongside his International teammates.
Stars were born at the 2022 Presidents Cup, but Matsuyama has been “growing the game” for what feels like a lifetime. Labeled from an early age as the savior for Japanese golf, Hideki has delivered time and time again. The former young prodigy has slowly but surely turned into a pillar of global golf and leader of the Internationals.
After a slow start, Hideki was able to grind out a win and a tie to help the Internationals remain competitive throughout the weekend.
While the Internationals were eventually defeated 17.5-12.5, a more important mission that cannot be measured by wins and losses was undoubtedly accomplished.
Amongst all of the turmoil and strife in the world golf, it’s easy to forget how much the game means to so many people.
Countless young golfers across the world went to bed on Sunday night and dreamt of being the next Tom Kim, Si Woo Kim or Hideki Matsuyama.
That sounds like an excellent way to “grow the game”.
2022 Alfred Dunhill Links Championship: Betting Picks & Selections
After an enthralling weekend, things get back on track with ‘standard’ 72-hole events on both sides of the pond.
In Europe, the DP World Tour continues an excellent, varied, schedule by hosting the 21st running of the Alfred Dunhill Links Championship, taking in rounds at Kingsbarns, Carnoustie and St. Andrews, before finishing the pro-am format at the Home of Golf.
It’s been just a few weeks since Cam Smith broke Rory McIlroy’s heart here at the 150th Open, and much has changed since, most notably the Aussie’s defection to the LIV tour. Given the proliferation of amateurs, the course won’t be set up anywhere near as tough as it was in August, but with some wind and rain expected, it will be as unpredictable as we can get it.
The PGA Tour resumes the always-bizarre wraparound season, this time at the Sanderson Farms, once an ‘opposite’ event, but now a fully fledged member of the schedule.
‘Average’ is the word I’d use to describe this event, as that is exactly what it is.
Average width, average length, average greens, and whilst fairways and greens will always help, the last four winners have ranked in the top four for strokes gained off the tee. 2018 champion, Cameron Champ, summed it up best by saying, “I felt like if I was further up, even in the rough versus hitting a 3-wood being 40 yards back, I would rather be up there. I guess that’s the game plan.”
Here are this week’s best bets at each:
Robert MacIntyre 33/1
Thorbjorn Oleson 66/1
Ewen Ferguson 100/1
The top of the market is predictably strong, with the ‘best’ player in the world, Rory McIlroy, rightly heading the market. However, backing golfers at 9/2 will not make anyone rich, especially given the way Rory has failed to convert chances here and recently at The Open, Wentworth and at the Italian Open.
Given links courses in Autumn offer a unique test, it is no surprise to see home players have won two-thirds of the 21 events held here so far, with the first seven being won by either an Englishman, Scot, or Pádraig Harrington.
That theme can continue this week with the back-in-form Robert MacIntyre, a player that may well be sitting on the odds-list next to Tyrrell Hatton before too long.
The 26-year-old has long been considered a high-class recruit to the professional ranks, and while we always expect more, the eventual second win in Italy has to have settled any self-doubt.
The Scot has been on the tour for just over three seasons, so it’s tough to feel disappointed at a record that shows five top three finishes and 12 further top-10s.
Included in those top performances are a pair of top-10s at The Open at Portrush and St. George’s, where a better tee-shot on the final par-five would have resulted in a comfortable top five, and a tied-12th at The Masters, easily good enough and significant enough to be competitive in this grade, and on a course that will suit.
MacIntyre’s versatility has already been shown with his wins at the gettable Cyprus Showdown and most recently at the far tougher Italian Open, coming through the field on Saturday, before shooting the lights out on Payday, eventually beating Matt Fitzpatrick in a play-off.
Previous best efforts of 2022 were 13th at Mount Juliet and 12th in Himmerland, both courses with an eye on the factors required here, whilst his stats have settled into a decent level – top-7 in tee-to-green for three of his last four events – with everything working around his natural ability.
Just after the Scottish Open in July, he admitted that, “My head hasn’t been right. I’m getting down on myself pretty easily. When it all clicks in and I start getting momentum going, I’ll be back to myself. Golf’s a funny game and it’s not been kind to me just now, but it will be.”
He’s back, and the best bet of the week.
Given the bookmakers often react quickly to form changes, back up the Scot with players that may look out of form, but arrive at conditions that suit much better.
Thorbjorn Olesen is one of those players that is very hard to read, but when showing something, and getting to windy links, he is an almost must-bet.
First and second around here in eight starts, the Dane has had a tumultuous couple of years, but looks to be close to his best once again, a best that includes top performances in .
It may have involved a bit of a closer finish than desired, but the one-shot victory at The Belfry in May came after showing a bit at both Abu Dhabi and Qatar, more evidence to his liking of windy Middle East tracks.
It’s true that he’s been very in-and-out since then, but in both Italy and France, his overall figures point to a player in full control of his game. Yes, we must forgive the poor performance on the greens at Le Golf National, but these are a completely different test and I’d wager he will return to the positive putting figures of his previous six outings.
Having withdrawn from the BMW International in June, the 32-year-old has four top-20 finishes, 22nd and 30th finishes on the card, returns to a favoured venue, and can make his way again up to the top echelons of the tour.
I’ll continue to put up Ewen Ferguson as he seems to drift further down the market each week as, frankly, a convincing two-time winner should not be triple-figures, especially he could legitimately be chasing a fifth title of the year this week.
As discussed multiple times, the 26-year-old wasn’t experienced enough in contention to take advantage of a final round lead in Kenya, but used that when out-grinding his opposition in Qatar, and proving far too good for compatriot Connor Syme and co at Galgorm Castle.
Just two weeks later, Ferguson was the best player on the Himmerland course, only to be denied by Oliver Wilson’s bizarre putting, a result that links in very well here. After all, the Englishman has only ever won twice, his first being here in 2014.
The Glasgow-born player is the only golfer to have held the British Boys, Scottish Strokeplay and Matchplay titles at the same time, his win at Royal Liverpool in 2013 coming via a comprehensive 10 & 9 victory. Winning the Scottish Champion of Champions and finishing in third place at the Irish Amateur Open led to a place on the 2016 Walker Cup team where he contributed one win from two singles matches (beating Maverick McNealy) in a comprehensive victory over a certain Bryson DeChambeau et al.
Shut your eyes and ignore the last two missed-cuts. This event should mean he can load up on his driving, allowing his top-grade iron play to present plenty of chances to return to the ranking of first for tee-to-green that he showed in Ireland and Denmark.
Coming off such a highly strung Presidents Cup may not suit the obvious pick Sam Burns, especially after a series of results that won’t flatter him. Still, should he win, that would be the third leg of a Max Homa-Team USA-Burns three-peat of 2021. It doesn’t happen.
In a tough event to start the year proper, just a couple to be with.
Start the plan off with Sahith Theegala to gain revenge on the event that first made his name.
Just the fifth person to win the Haskins, Hogan and Nicklaus awards in college, the Pepperdine athlete was always going to do something in the professional game, but few thought it would come in his second event as a full PGA Tour player.
12 months ago, the 24-year-old shot a bogey-free third round 67 to take a lead into the final round at the Country Club of Jackson, but faded to finish in eighth place behind Sam Burns after a bizarre attempt to hit the hero shot from a bunker. Absolutely no connection with Ewen Ferguson at all, except that he too faded from the lead to 8th on his first attempt at landing a title with an overnight lead, and he soon won twice.
Like the Scot, Theegala learned from the experience to lie in sixth at Torrey Pines, before a sponsor’s exemption allowed him into the Raucous Phoenix Open, where again he took a lead into the final round. This time, he lasted to the short par-four 17th, when fate would conspire against him, a bad bounce leaving his ball in a water hazard, and costing him that vital shot that left him out of the final play-off, one that served up the first win for eventual world number one, Scottie Scheffler.
What has followed has been a steady flow of improvement, coming from behind to finish seventh in the Valspar, fifth at Muirfield, second at the Travelers and 16th at Deere Run before a run at the FedEx finals, eventually qualifying for the Tour Championship. The knowledge he is among the best of the maidens on tour should have given him confidence for the 2022/23 season, and supporters cannot ask for more than an opening sixth place at the Fortinet, when he was never outside of the top 10.
Expect a victory this season – it’s where, not if.
Is Benny back?
Subject of the best of Sam Harrop’s parody songs, Byeong-Hun An (as he is officially named) would be one of the most popular winners of recent times, and after an extremely encouraging opener, is worth taking the chance with at the price.
The youngest-ever winner of the U.S Amateur, when winning 7&5, he should have made the following year’s qualifier, giving way late in his semi-final. It wasn’t long, however, before he made his way through the ranks, winning the BMW at Wentworth in just his first full season on the European Tour, gaging up by six shots from Thongchai Jaidee and Miguel Angel Jimenez.
And it’s not gone quite right since, all down to the putter – back to Sam again:
Let’s concentrate on the positives – which may include the player sending the crooner one of his own putters – and witness significant improvement over the last few months.
Down a level on the KFT, Benny found something from somewhere, winning his first event for five years at the Suncoast Classic, his seventh best performance according to the OWGR.
Almost certainly securing his card, the Korean followed up his win with a never-nearer 12th and second in April, and lay inside the top 10 before the final round at Memorial Health in July, whilst in-between he nabbed 14th place alongside Sungjae Im.
Two weeks after the Korn Ferry Tour finals, Benny was back on the PGA Tour with a bang, finishing in fourth behind defending champion Max Homa and Danny Willett, the latter a winner of both the BMW PGA and Alfred Dunhill Links.
Ranking second in driving, third in tee-to-green, fourth for around-the-green and better than field average for putting.
If he’s back, and has confidence in the short stick, there is no reason he can’t repeat his 2019 effort here, when third on debut.
