Here’s a great drill that will help to create awareness of where the clubface is angled at impact…
Keep in mind that the clubface is PRIMARILY responsible for where the ball launches, while the clubpath is PRIMARILY responsible for the curvature of the shot. If you know the predominant shape of your shots, the key is to launch the ball in the proper direction – this drill will help! Give it a try and please let me know if you’ve made any progress.
I have never taught a predominant slicer that did not always have their clubpath travelling from out to in on a very consistent basis. I have never taught a predominant hooker that did not always have their clubpath travelling from in to out on a very consistent basis. In order to upgrade these golfers’ ball flight we needed to improve their path first and then work to adjust the face to point somewhere between the path and the target line.
Here is an example of a lesson I might give to a golfer who predominantly fades/slices the golf ball:
I hope these two clips help you to better understand what it is you need to do to improve your ball flight and have more fun out on the golf course.
There has been a fair amount of banter online recently regarding various topics and I thought it would help both of us if I jotted down a few thoughts:
A functional draw is one that finishes at the target – something many of us strive for. In order to hit functional draws you need a clubpath that is traveling outward (in to out) and a clubface that is angled slightly closed relative to the clubpath, yet open to the target (assuming center contact).
It is possible to hit both functional draws, ones that finish at the target, and bad draws, ones that move away from the target, with a clubface that is open, square and closed to the target at impact. You can even hit good and bad draws with the appropriate clubpath, but I believe an outward moving clubpath is integral to hitting functional draws. And here’s why…
I am yet to teach a golfer who fades the ball that consistently swings from in to out!
Clubpath is king and clubface is queen – I might get the desired shot shape with clubface, but I cannot get the desired result without clubpath. It is simply not possible to hit a functional draw with a clubpath that travels from out to in (assuming center contact). It is clearly not the only thing, but in my opinion it is the most important thing.
I am well aware there are many different ways to achieve this and whether as a coach or golfer you upgrade the clubface first or the clubpath first is entirely up to you. After all it’s all about results no?
Many golfers and TrackMan users are under the impression that smash factor indicates how well a ball was hit, or how centered the strike was – this is not necessarily the case. A high smash factor purely indicates high ball speed relative to club speed. Here is the simplified formula:
It is quite possible to have a smash factor with irons that is too high. Golfers who play from a closed face position and who tend to flight the ball low will often have a higher smash factor than golfers who flight the ball appropriately. This does not mean the low ball hitters are striking it better, it just means they are generating too much linear ball speed off of a particular club.
It is important for golfers to understand that ball type and condition, dynamic loft, clubhead mass, attack angle, CoR and of course quality of strike go into determining the smash factor for any given shot. If you don’t believe me take a look at the real formula for smash factor:
The objective with the driver should 1.50 or higher, but with the shorter clubs a higher smash just might not necessarily better. Go for solid hits and ball flight over smash factor any day!
A Note to Golf Coaches:
I have made more than my fair share of mistakes in life. From these mistakes I have learned and improved as a coach and a person. One of the many valuable lessons I have learned from making mistakes is to never deride, belittle or insult another golf coach. It does nothing to enhance your image or reputation and you will never look better while attempting to make someone else look worse. Be wise when addressing other coaches and the methods they employ – you’ll be better off for it.
We should all be looking to spin the ball around the greens. Which of the current crop of wedges will give us the best chance to do that? If you have read any of my previous research on wedges you will know that friction between the face and the ball plays a huge role, not only in generating spin, but also in lowering trajectory – both vitally important for control.
The most important part of the clubface of any wedge is not the grooves, but the texturing of the flat areas between the grooves. Keep in mind that the primary purpose of grooves is to channel “matter” away from being caught between the flat areas and the ball – they are not in place to create spin. When you look carefully at the flat areas between the grooves of your wedge you should see some fine milling which looks like corduroy to me. Most club manufacturers will mill the clubface of their premium wedges and it makes a massive difference to the control and ball flight.
The idea behind the test was to see which wedge generated the better grip between face and ball. I had four very new 58 degree wedges available for the test:
- Titleist Vokey SM4 with a DG Spinner shaft – conforming grooves with standard mill pattern on face
- Ping Gorge Tour with a DG Spinner shaft – conforming “gorge” grooves with standard mill pattern on face
- Callaway X Series Jaws CC with a stock steel shaft – additional conforming grooves with no apparent milling on face
- TaylorMade ATV with a KBS shaft – conforming grooves with two-way mill pattern on face
You may notice that the wedges had differing shafts – I obviously would have preferred to have had all the clubs built to the exact same specs, but that was not feasible for this test. Apologies to all Cleveland Golf fans – would love to have had a Cleveland wedge in the mix, but did not have a new version. I had four golf professionals each hit four shots with each wedge. All shots were hit off a mat in order to limit friction being interrupted by matter being caught between face and ball. Titleist ProV1 golf balls were used and each shot had to land somewhere between 40 and 60 yards (ideally at 50 yards). The clubface was cleaned often even though it never appeared to need it. The “normalize” feature on TrackMan was off.
Here are the results:
- ATV 7365 rpm average
- Vokey 7210 rpm average
- Gorge 7193 rpm average
- Jaws 7163 rpm average
As you can see the ATV wedge led the way in generating the highest spin of the four – albeit by a slender 2%. If I was a betting man I would have bet the ATV would generate the most spin as I have always loved the two-way milling treatment on the face. I would also have placed the Jaws wedge at the bottom of the pack, as no matter how many groove edges come in contact with the ball, there is way more flat surface area contacting the ball and it should be milled.
If you do take one thing from this research let it be the following: A fresh wedge with a clean, milled clubface will allow you to generate more spin and a lower trajectory – both important factors in controlling your golf ball around the greens.

There is so much complex information out there regarding the Ball Flight Laws – a ten second Google search yields enough confusion to get my head spinning for a month. The “old” or “new” ball flight laws, Dr. Wiren, TrackMan…..who or what should you believe?
In light of Dr. Einstein‘s insightful quote I am going to give this touchy topic my best shot and try to keep it as simple as possible. Please don’t check out! This is important information for any golfer to comprehend, so bear with me and you’ll gain a far better understanding of why your golf ball reacts the way it does.
There are only four factors that influence ball flight when clean (not necessarily solid) contact is made between a golfball and a clubface.
The faster the clubhead travels the further and higher the ball will travel – generally with more spin. Compare a chip (slow speed) with a pitching wedge vs. a full swing (faster speed) with a pitching wedge…simple enough.
Orientation is a fancy term that refers to where the clubface is angled. Keep in mind that the face angles both left or right or up or down – left or right being an open or closed face and the up/down variable (although hopefully never down) referring to the loft imparted at impact (dynamic loft). The face angle largely determines where the ball launches – left or right of the target and at what angle relative to the ground. A good general point to remember is clubface (for the most part) = launch.
Once again the direction the clubhead travels relative to the target line at impact – left or right (clubpath) and up or down (attack angle) – plays a role in determining ball flight. A lesser role than the clubface, but a role nonetheless. A good general point to remember is clubpath (for the most part) = curve.
Centerdness of Contact
This is a big one and something the vast majority of teachers and golfers tend to underestimate. Most golfers strike the ball on the sweet spot far less frequently than they think . I often see golfers that swing for a draw, yet strike for a fade – in other words they have a clubpath that is in to out, yet hit the ball slightly out the heel which leads to a fade. An off center point of contact on the face leads to gear effect, which overrides or reduces the effect the face orientation and clubhead direction have on ball flight. This factor plays a bigger role than most realize – watch out for it. And the best way to do that – a spray of Dr. Scholl’s foot powder.
Here are a few simple factors to understand and remember:
- The ball launches primarily in the direction of the face – varying degrees of up and either left or right.
- Given a centered hit, clubpath leads to curve. With the curve being away from the clubpath.
- Hitting down does not increase spin, and conversely, hitting up does not necessarily reduce spin.
- Heel hits encourage fades or reduce hooks and toe hits encourage draws or reduce slices.
- The more you hit down on the ball, the more you will swing in to out and the more you hit up on the ball the more you will swing out to in.
