How to eliminate the double cross: Vertical plane, gear effect and impact location

Published

on

One of the biggest issues teachers see on the lesson tee is an out-to-in golf swing from a player who is trying to fade the ball, only to look up and see the deadly double cross! This gear effect assisted toe hook is one of the most frustrating things about trying to move the ball from left to right for the right-handed golfer. In this article, I want to show you what this looks like with Trackman and give you a few ways in which you can eliminate this from your game.

Below is the address position of a golfer I teach here in Punta Mita; his handicap ranges between scratch and 2, depending on how much he’s playing, but his miss is a double cross when he’s struggling.

Now let’s examine his impact position:

Observations

  • You see a pull-hooking ball flight
  • The hands are significantly higher at impact than they were at address
  • If you look at the clubhead closely you can see it is wide open post impact due to a toe hit (which we’ll see more of in a second)
  • The face to path is 0.5 which means with a perfectly centered hit, this ball would have moved very slightly from the left to the right
  • However, we see a shot that has a very high negative spin axis -13.7 showing a shot that is moving right to left

Now let’s look at impact location via Trackman:

As we can see here, the impact of the shot above was obviously on the toe and this is the reason why the double-cross occurred. Now the question remains is “why did he hit the ball off of the toe?”

This is what I see from people who swing a touch too much from out-to-in and try to hit fades: a standing up of the body and a lifting of the hands raising the Vertical Swing Plane and Dynamic Lie of the club at impact. From address, let’s assume his lie angle was 45 degrees (for simplicity) and now at impact you can see his Dynamic Lie is 51 degrees. Simply put, he’s standing up the shaft during impact…when this happens you will tend to pull the heel off the ground at impact and this exposes the toe of the club, hence the toe hits and the gear effect toe hook.

Now that we know the problem, what’s the solution? In my opinion it’s a three stage process:

  1. Don’t swing as much from out-to-in so you won’t stand up as much during impact
  2. A better swing plane will help you to remain in your posture and lower the hands a touch more through impact
  3. Move the weights in your driver to promote a slight fade bias

Obviously the key here is to make better swings, but remember to use technology to your advantage and understand why these type of things happen!

    In general players stand up to compensate for an open club face. They lack control of the face. The movement up is to try and square the face. Love to see the shaft and wrist angles in transition. I’d guess the shaft is very vertical and wrist is cupped. Also guessing hand depth is lacking in transition.

    There are 2 gear effects, a horizontal and a vertical gear effect on drivers with a bulge and roll face. Horizontal gear effect is optimal at the sweet spot and the vertical gear effect optimizes slightly above the geometric center of the face. As for Twist Face???

    Didn’t he hit the toe, just because, you know, he hit the toe? He could make virtually the same swing but his hands are less than an inch in a different position and then hit the sweet spot. Why make such large changes to body movement to correct such slight an error in motion? Seems like a good way to clutter the mind and cause worse contact.

    In the two freeze frame videos of the man swinging, it just doesn’t look to me like he’s aimed far enough left with his feet or his hips, and so the plane doesn’t look correct, as he is really didn’t swing enough out-to-in with a slice move to try to fade the ball like Trevino or Nicklaus. He looks like he aimed square and swung down the line, straight on plane, may be slightly over the top if at all, to try to promote a out-to-in from high to low, but definitely not significantly out-to-in slice swing enough down his feet line to the left, even a la TW when he did that swoop with Foley.
    This is a bad example of a poor swing executed, but an impact location executed well to demonstrate a properly a gear-effect hook from a square position. Why didn’t he take a giant slice swing like a flop shot or bunker shot with the driver, an extreme slice swing, and still hit that toe area to demonstrate that the extreme slice swing can also offset a toe hit and actually make the ball go mostly straight?
    Shank to this one.

    Good explanation, but not much in the way of instructing anyone how to go about the first two stages of your three stage process. Stage 3 is kind of a no-brainer though anyone struggling with hooks has already pulled out the wrench if their driver allows it, but moving a weight on the bottom of the club isn’t going to stop gear effect if you still hit one out on the toe.

      Moving the weight will shift the CG and will indeed help change/reduce gear effect.

        No, trying to remedy the problem at the clubhead is insignificant if the wrists rise and the clubhead droops for a toe hit. The problem is in the hands and arms, not the clubhead.

    This is good stuff! Why do rec golfers instinctively tend to straighten up as they approach impact? How can we overcome our instincts and stay down into the swing going into impact? Why do the hip and knee joints extend as the club comes down? Thanks.

      You should watch a few Wisdom in Golf videos by Shawn Clement. They are here on the site. Rec golfers stand up and extend early because they are too focused on *hitting the ball* when they should be focused on delivering the energy of a swing through the ball.

        Okay, but what is the physiological reason to instinctively ‘stand up’ when the clubhead is coming down to impact? “..focusing on delivering the energy of a swing through the ball” is the result of standing up. It’s not an answer to the problem.

      Telling a golfer to stop standing up at impact is complete rubbish. The subconscious cannot , Not do something. Golf instructors need to learn how the body maintains balance, subconsciously.
      Interpreting Trackman data to correct EE, is BS baffles brains.

Clement: Laid-off or perfect fade? Across-the-line or perfect draw?

Published

Some call the image on the left laid off, but if you are hitting a fade, this could be a perfect backswing for it! Same for across the line for a draw! Stop racking your brain with perceived mistakes and simply match backswing to shot shape!

The Wedge Guy: The easiest-to-learn golf basic

Published

on

My golf learning began with this simple fact – if you don’t have a fundamentally sound hold on the golf club, it is practically impossible for your body to execute a fundamentally sound golf swing. I’m still a big believer that the golf swing is much easier to execute if you begin with the proper hold on the club.

As you might imagine, I come into contact with hundreds of golfers of all skill levels. And it is very rare to see a good player with a bad hold on the golf club. There are some exceptions, for sure, but they are very few and very far between, and they typically have beat so many balls with their poor grip that they’ve found a way to work around it.

The reality of biophysics is that the body moves only in certain ways – and the particulars of the way you hold the golf club can totally prevent a sound swing motion that allows the club to release properly through the impact zone. The wonderful thing is that anyone can learn how to put a fundamentally sound hold on the golf club, and you can practice it anywhere your hands are not otherwise engaged, like watching TV or just sitting and relaxing.

Whether you prefer an overlap, interlock or full-finger (not baseball!) grip on the club, the same fundamentals apply.  Here are the major grip faults I see most often, in the order of the frequency:

Mis-aligned hands

By this I mean that the palms of the two hands are not parallel to each other. Too many golfers have a weak left hand and strong right, or vice versa. The easiest way to learn how to hold the club with your palms aligned properly is to grip a plain wooden ruler or yardstick. It forces the hands to align properly and shows you how that feels. If you grip and re-grip a yardstick several times, then grip a club, you’ll see that the learning curve is almost immediate.

The position of the grip in the upper/left hand

I also observe many golfers who have the butt of the grip too far into the heel pad of the upper hand (the left hand for right-handed players). It’s amazing how much easier it is to release the club through the ball if even 1/4-1/2″ of the butt is beyond the left heel pad. Try this yourself to see what I mean.  Swing the club freely with just your left hand and notice the difference in its release from when you hold it at the end of the grip, versus gripping down even a half inch.

To help you really understand how this works, go to the range and hit shots with your five-iron gripped down a full inch to make the club the same length as your seven-iron. You will probably see an amazing shot shape difference, and likely not see as much distance loss as you would expect.

Too much lower (right) hand on the club

It seems like almost all golfers of 8-10 handicap or higher have the club too far into the palm of the lower hand, because that feels “good” if you are trying to control the path of the clubhead to the ball. But the golf swing is not an effort to hit at the ball – it is a swing of the club. The proper hold on the club has the grip underneath the pad at the base of the fingers. This will likely feel “weak” to you — like you cannot control the club like that. EXACTLY. You should not be trying to control the club with your lower/master hand.

Gripping too tightly

Nearly all golfers hold the club too tightly, which tenses up the forearms and prevents a proper release of the club through impact. In order for the club to move back and through properly, you must feel that the club is controlled by the last three fingers of the upper hand, and the middle two fingers of the lower hand. If you engage your thumbs and forefingers in “holding” the club, the result will almost always be a grip that is too tight. Try this for yourself. Hold the club in your upper hand only, and squeeze firmly with just the last three fingers, with the forefinger and thumb off the club entirely. You have good control, but your forearms are not tense. Then begin to squeeze down with your thumb and forefinger and observe the tensing of the entire forearm. This is the way we are made, so the key to preventing tenseness in the arms is to hold the club very lightly with the “pinchers” — the thumbs and forefingers.

So, those are what I believe are the four fundamentals of a good grip. Anyone can learn them in their home or office very quickly. There is no easier way to improve your ball striking consistency and add distance than giving more attention to the way you hold the golf club.

Clement: Stop ripping off your swing with this drill!

Published

on

Not the dreaded headcover under the armpit drill! As if your body is defective and can’t function by itself! Have you seen how incredible the human machine is with all the incredible feats of agility all kinds of athletes are accomplishing? You think your body is so defective (the good Lord is laughing his head off at you) that it needs a headcover tucked under the armpit so you can swing like T-Rex?
