Five Things We Learned: Thursday at the PGA Championship
It was a year ago that we the north, found ourselves with toes and fingers crossed. The Oak Hill PGA Championship of 2023 finished on schedule, despite the iffiness of weather in upstate New York. It’s 75 degrees today across the Niagara Frontier, which makes it two out of three (2022 was the same way) for sultry, unseasonal weather.
Louisville is, let’s be honest, a much better bet for a May PGA Championship, and Valhalla is an exciting venue for the year’s second major championship on the men’s circuit. Brooks Koepka came in as the defending champion, and Rory McIlroy arrived as the last golfer to win a major at the Nicklaus-designed course. That was a decade ago, and lord, have things changed in the world and golf.
Day one at Valhalla offered walk-in eagles, buckets of birdies, and potential for a record-low, winner’s score. We’ll get right to the meat of the matter, with five things that we learned. After all, if you can make par from the muck, anything’s possible in the land of the horses.

1. X marks this spot
Xander Schauffele went head-to-head last Sunday with Rory McIlroy, at least on the practice green. By the end of the round, Rors had won for a fourth time at Charlotte, while the X Man sat scratching his head, wondering what went wrong. Fortunately for us, Xander didn’t sulk.
The San Diego State alumnus absolutely torched Jack’s track with 62. Four birdies on the front nine, were followed by five more on the inward side. Schauffele never looked as if bogey was a consideration, and he might have gone even lower. Despite winning the Covid-delayed Gold medal at the Japan Olympics (I consider it a major, btdubs) Schauffele continues to chase an initial men’s major, and the validation that it brings. If 62 doesn’t get you over the hump, who knows what will.

2. Scottie starts strong? Aye.
Last month, Mr. Scheffler won a second green jacket at Augusta National. Last year in Rochester, Mr. Scheffler tied for second in this event. Mr. Scheffler began play today with a walk-in eagle, a one-hop affair that never looked as if it might go anywhere but to its home. Scheffler had a few rough holes, but that’s to be expected from a new dad. Each time he made bogey, he bounced back with birdie, so he has that short memory that winners crave. Surprisingly, Scheffler failed to manage one last birdie at the reachable 18th. Perhaps that miss will motivate him in round two.

3. LIV Check-In
It’s good to check in on the departed from time to time, to ensure that the fellows formerly known as PGA Tour members are doing well. It’s safe to say that some of them can still play. Defending champion Brooks Koepka posted 67 on the day, He had an eagle and three birdies on the day, with only a stumble at the 17th. He’s tied for 7th. Bryson DeChambeau made an eagle of his own, but also had a bogey, at the 12th hole. He cohabits eleventh position with Cameron Smith, who ALSO had a bogey on his card. They are one shot behind Koepka, and a fistful more behind the leader.
ON THE MONEY ?

4. Sahith and Tony at Schauffele’s heels
Both Finau and Theegala represent a special sort of athletic golfer. Their power and their charisma blend to draw golf fans to their groups. Let’s be honest, too, and say that they don’t look like the traditional professional golfer. As much as Tiger Woods did in the 1990s, they have the power to bring greater diversity to the sport.
In terms of their play today, well, only Xander was better. Finau had a clean card, with six birdies and twelve pars. Theegala had seven birdies, ten pars, and one bogey. Each combined power and finesse to insert themselves squarely in contention, ahead of round two. How will they, and Xander as well, manage the afternoon putting surface on Friday? That’s the great unknown!
SAHITH. THEEGALA. ?
This hole out puts him in a tie for the lead early at the #PGAChamp.

5. All those other guys are here!
Rory, Tom Kim, Collin, and Viktor are all at minus-three or lower. Valhalla may not be a traditional golf course, but it is the type of course that the world’s best play well. McIlroy currently sits at minus-five, tied with Robert MacIntyre, Kim, and three others in fourth position. Maverick McNealy finished fast to reach the same figure, as did Tom Hoge. Morikawa closed with birdie to join the sextet at five below. Both Scheffler and Morikawa finished their rounds late on Thursday, meaning they should see smoother greens on Friday morning. If someone is a betting soul, wiser wagers could not be placed on better names than those two, two-time, major champions. Rory will tee off in Friday’s afternoon wave but, hey, he’s Rory, and he won going away last week at Quail Hollow, a course not unlike Valhalla.
The 2020 PGA Champion is making moves.

Experts on understanding ground force and how shoes can impact your golf game
Back in 2021, GolfWRX wanted to learn more about the data surrounding Sqairz golf shoes’ bold performance claims. We talked with Terry Hashimoto, co-founder of BodiTrak, who tested (and continues to test) golfer performance when wearing the company’s shoes.
Hashimoto’s research showed the average gains for golfers wearing Sqairz shoes compared to the golfers’ previous footwear was an average of an 8-yard extra carry distance, 13mph increased ball speed, 11-degrees increase in hip rotation, and a greater smash factor of 7%. Sqairz wearers leveraged the company’s industry-leading ground connection for better balance, energy exchange, and weight transfer for better ball speed and carry numbers.
As a refresher, here’s what we said about Sqairz golf shoe technology.
At the heart of the design behind the technologically advanced shoes is the patented squared toe. The interior design of the square toe allows the golfer’s toes to sit comfortably in the shoe, with a wider base and a heel stabilizer designed to provide enhanced balance and stability. The square toe also allows golfers a unique freedom for their toes to sit naturally with a full range of motion and a noticeable feel for the ground.
Sqairz testing found that added flexibility in competitive sneaker-like golf shoes promoted inversion, the foot (weight) moving to the outside of the trail foot. This is when the golfer gets stuck on the right side (for right-handed golfers) and not being able to shift the weight back to the lead side.
With the Sqairz golf shoe, golfers are provided with a structured upper material often used in sports such as football and soccer to provide structure for sudden weight shifts. Along with this upper material, the outsole and midsole have been optimized for the right amount of flexibility to promote efficient energy exchange and stability. In addition, Sqairz has engineered a heel stabilizer that keeps the heel down throughout the swing and prevents ankle roll-over injuries on all types of lies.
Sqairz shoes also feature the widest base and greatest amount of ground coverage of any golf shoe, which is proven to provide better balance and stability as well as offer efficient braking power. Braking occurs towards the end of the backswing and immediately before the ball is struck. Golfers shift the weight from the trail to the lead side and this optimized braking at the right time allows for increased swing speed.
To take the conversation further, we caught up with Hashimoto again, as well as Tyler Standifird, who is a Professor of Biomechanics and Kinesiology at Utah Valley University and a sports performance researcher.
GolfWRX: What is ground force, in simple terms, for the golfer who has heard it mentioned but doesn’t really understand what it is?
TH: How we use the ground during our swing to effect optimal performance.
TS: Ground reaction force is based on Newton’s 3rd law, which is the action-reaction law. Ground reaction force is the force exerted by the ground as a reaction to internal pushes, forces from our muscles and bodies. A desk won’t move on its own, it can only push on the ground at the same value, minute by minute year by year. But humans have the capacity to alter their interactions with the ground by using muscles to push on the ground to get altered forces from the ground that create motion in human movement.
GolfWRX: Why is ground force so important in the golf swing?
TH: Learning how to use the ground optimally will increase a golfer’s stability, range of motion, and lateral speed leading to greater ball speed, distance, and tighter dispersion.
TS: The ground is one of our two connections in the golf swing. It is impossible to create the motion you want in the golf swing without proper GRF. Just imagine swinging a golf club on ice, or in slippery conditions, it is incredibly difficult and takes out a key source of your power, the legs and the ground. GRF in the golf swing is what allows us to create efficient powerful swings, with forces that occur at the right time in the swing, in the right direction, and with the correct magnitude.
GolfWRX: Growing up, golf instruction rarely seemed to mention the ground — or “using the ground” — why is this? How are things different now?
TH: That’s so true. It wasn’t until we started developing portable pressure mapping systems, BodiTrak being the 1st and traveling all over the world with Top Coaches and Players on all tours were we able to see consistent common denominators for all the shots required…from the putting to chipping to short iron play, long irons, hybrids, fairway wood and ESPECIALLY in the Driver we’re we able to share with the world the most relevant applications of how to use the ground. But wait, there’s one thing to consider…
What initiates the backswing? Would you ever get in your car – put it in drive before you started your car? NO is the obvious answer and it turns out this answer has THE most effective change on the Kinematic Sequence
TS: I think it is due to a bit of progress in technology and the availability of researchers and coaches. It’s like a trackman or other launch monitor, a lot of it wasn’t talked about until we could collect data, see numbers, and start to understand how they work together. GRF technology used to be reserved for high-level research labs, most of which were not doing research related to golf. Now there are a number of great labs at research Universities, and coaches using force plates to measure GRF and understand how it can help a player improve. Because force is invisible, we needed to start measuring it to really truly understand what a golfer was doing as a result of data collection. We needed to understand the principle of GRF before we could be confident explaining it to students. Now that we know so much more about how it works in the swing, it is something that can be an awesome teaching tool for coaches.
GolfWRX: How does a player “use the ground” optimally in the golf swing?
TS: Golfers use what we call the kinetic sequence. This is the process of how they synchronize the forces needed to move the body in efficient ways in the swing. It starts with a laterally directed force around the end of the backswing, the rotational forces called torques come next early in the downswing, and then a vertical push that comes very last but has to come prior to impact with the golf ball (maybe arm or club parallel on the downswing) so energy can be transferred out to the ball. Creating the proper order, at the right time is important to a proper golf swing.
GolfWRX: Since your feet are your only connection with the ground, it follows that shoes are a not unimportant piece, or are they? How much does footwear matter in the golf swing?
TH: Although not well known I’ve been designing golf clubs, shaft fitting systems, really popular products used by golfers all over the world, and 1000s of top instructors worldwide, the thing that drove me nuts is how golf shoes are designed…
The trail and lead side of your foot have completely different needs and even though we designed the FJ many years ago, it wasn’t until I started working with Sqairz, that I started to get some of the stability, mobility, and combination of both answers.
TS: I love footwear. I have researched it a lot in other sports and it can make a big difference to athletes. The footwear first and foremost needs to be comfortable enough for the player to wear during their round. Without that comfort component, performance doesn’t really matter much. I’d say that I think potentially there are a lot of golfers who could benefit a lot from proper footwear. For example, some golfers lack the proper stability in the feet/ground due to a shoe that allows too much movement in the shoe. In order to really understand, I always encourage golfers to hit some golf balls in different shoes and look at numbers/data to see how they feel. I’ve seen athletes, including golfers, gain a lot from getting the right footwear for their body and movements.
GolfWRX: If a player wears, say, shoes without spikes vs some sort of wide-based, structured shoe with SoftSpikes or the like (eg, Sqairz), how much of a difference will s/he see?
TH: We’ve seen distance gains using Sqairz shoes all over from 7 to 20 yards. Now they have shoes designed for lateral, rotation, and combo swinger, and I can’t wait to see with what they come up with next…
TS: So the name of the game with the shoe/ground experience is friction. Creating the correct connection with the ground so that a player can confidently interact with the ground without slipping. Here is a good example, the trail foot has to push really hard into the ground and away from the target in the backswing, with a secure connection with the ground, the ground will push back with a GRF that is pointed towards the target, helping them to initiate some motion forward in the golf swing. Now if they go to push and they were on ice, the foot would just go in the direction of the movement and the foot would slip out from under them. A key component of friction is the coefficient of friction, I tell my students it is the idea of how sticky the two surfaces contacting are. This is where cleats/cleatless and where the cleats are placed can play such a key role. They can really give the student the confidence to push on the ground with as much force as they can without fearing losing balance and stability.
Some players who play in a spikeless shoe with little traction may work just fine. My only concern is what are they leaving on the table. Simple numbers. If my shoe allows me to push on the ground with 100 Newtons of Force, but in my swing, I only can produce 80, then I won’t slip and I am fine with that shoe. But if I have the capacity to do 120 newtons of force then I have an issue, I either push with over 100 and slip a little, or I just push with 90 even though I can do more. It might be that people have almost started taking some athleticism out of their swing, because of their shoes. They think they don’t alter their game, but in reality, they are leaving some on the table. Like a basketball player who knows they will slip if they move too fast due to a bad court/shoes, they just move more slowly throughout the game as a result. I think similar things could be happening in the golf swing.
GolfWRX: Can you give us some background on some of the research projects related to everything we’ve been discussing?
TS: I did a great study headed by two of my students. Blake Morrill and Trevor Nielson. We tested golfers, 7 came through the lab at the latest data analysis, and we compared the Sqairz shoe to a spikeless flexible golf shoe. We had golfers hit a series of drivers while we measured trackman data and Ground reaction force during the swing. The trackman data showed a 5.5 mph increase in ball speed which was statistically different even with the small sample size. This led to a significant increase of 9 yards of carry distance. In terms of the force plate data, the trail leg force that creates part of the rotation in the golf swing was greater by almost 6% and was approaching significance, this would show a player had more ability to create rotational force with the trail leg. It was a small group, but the data showed that shoes can make a difference when looking at force production and ball speed/distance. We are excited to keep this study going, we’ve also measured foot mobility with my Colleague Dr. Melani Kelly to see if the golfers’ foot capabilities itself might lead to different data.
In my mind, we have barely scratched the surface of footwear in golf and it will be exciting to see what the future holds in terms of how we can understand footwear and how it can help a player create a better golf swing and hopefully play better golf!
