Hitting hooks and slices? Here’s how to control your ball’s curvature

Published

on

As with most golfers, controlling the curvature of the golf ball in flight tends to be the most common issue plaguing players’ consistency on a daily basis. While there are a ton of fundamental reasons why your swing is causing the ball to curve off-line, the simplest reason is this:

  • When your ball curves too much, you have a face-to-path ratio that is too diverse.

This ratio determines your ball’s spin axis, or the amount the ball will curve in the air in general. Now, I know an off-center hit coupled with the club’s gear effect can also influence the ball’s curvature, but for the sake of this article we will just assume that you have hit the middle of the blade to make things easier to understand.

first

So let’s examine the sample shot I hit above showing a big right-to-left curve:

  1. My target-line is the thin white line directly over the top of the golf balls I have placed at the end of the range.
  2. My path is 16 degrees from the inside to the outside as shown by the blue line.
  3. My face at impact is 3.6 degrees open. With a centered hit, whenever the face is left of the club’s path the ball will curve from right to left.
  4. Thus the ratio between my face (3.6-degrees open) and my path (16 in-to-out) at impact shows a difference of -12.4.
  5. This ball had a spin axis of -13.6, meaning it was curving left. This is shown by the purple curving line tracing the ball in flight.

KEY: Whenever you have a big difference between where you face is pointing and where your path is going, you will tend to have a big curve (as shown in the sample shot above.)  In order to hit the ball with less curve, you need a face-to-path ratio that is very low. This means that your path and your face are going in mostly the same direction give or take a degree or two, as shown below.

last

In order to hit the ball with very little curvature you will need a path and face angle that are more in-line!

One final thought. You can alter the alignment of your body at address to make up for a face-and-path relationship that are in-line, but a touch too much to the right or too much to the left of your target. Please do not alter your aim while you do the drill I’m describing.

So how do we train our hands and body to produce straighter golf shots with less curve, and what drill can you do on the range to best learn how to control this ratio? Line up square to your target-line and then make full-swings in slow-motion trying to hit the ball as straight as possible. Some amount of curvature is inevitable for the majority of players, but the goal is to have the least amount of curve possible while you are hitting these shots.

As you make these swings please, remember to hit the same shot over and over. This means hit the ball the same distance and with the same curvature tendency each time. The better you can get at this drill, the easier it will be for you to understand and feel how to hit the ball straighter when you go back to hitting full speed shots!

Enjoy the process and have some fun. At worst, you are designing a “B” game for yourself if your “A” game is in the tank that day!

    So basically for players who are struggling with their slice (and I’ve seen coaches do this so it’s not like I invented this) they can do an exaggerated draw with a more extreme inside out path, giving them a ton of room or angle to learn how to close their club face. I think if you tell someone to go from slicing to hitting it straight, it’s nearly impossible since the margin of error is so small. But like in the example, club path angle is basically how much margin of error (for the club face) you can have to hit the ball within the angle between the target line and the club path.

    To me the path is easier to be consistent about, but the face could mean on the green or in the bunker. Having a more extreme path allows the less skilled player to keep their misses to just one side of the target.

    If the club path and target line aligns with the left and right extremities of the green, then the chance of getting on green increases.

      Remember this is just a feel drill for people to “educate” their hands in order to understand clubhead/clubface control hitting baby shots This is NOT a cure all for path and face issues- it’s just the starting point.

    Tom,

    What club were you hitting?

    Open clubface to draw the ball, and closed clubface to fade it. Relative to the target that is!

    Nice work Tom!

      Not sure if this is in jest, but the opposite is true. I don’t want to mislead anyone that is new to the game. Closed=hook, open=Slice. The key in his example is that he hit a hook because even though the face was open, it was more closed than the swing path. The target means nothing really. For example, If the face is closed 5*, but the swing path is 7* left (out to in), you’ll slice.

The Wedge Guy: Short game tempo

Published

on

One of my favorite things to do is observe golfers closely, watching how they go about things from well before the shot to the execution of the swing or stroke. Guess the golf course has become kind of like going to the lab, in a way.

One thing I notice much too often is how “quick” most golfers are around the greens. It starts with grabbing a club or two from the cart and quickly getting to their ball. Then a few short jabs at a practice swing and usually a less-than-stellar result at a recovery.

Why?

If you are going to spend a morning or afternoon on the course, why hurry around the greens? I tend to be a fast player and despise five-hour rounds, but don’t fault anyone for taking a few seconds extra to get “right” with their recovery shot. You can still play “ready golf” and not short yourself in the close attention to execution. But let me get back to the specific topic.

Maybe it’s aggravated by this rush, but most golfers I observe have a short game tempo that is too quick. Chips, pitches and recoveries are precision swings at less than full power, so they require a tempo that is slower than you might think to accommodate that precision. They are outside the “norm” of a golf swing, so give yourself several practice swings to get a feel for the tempo and power that needs to be applied to the shot at hand.

I also think this quick tempo is a result of the old adage “accelerate through the ball.” We’ve all had that pounded into our brains since we started playing, but my contention is that it is darn hard not to accelerate . . . it’s a natural order of the swing. But to mentally focus on that idea tends to produce a short, choppy swing, with no rhythm or precision. So, here’s a practice drill for you.

  1. Go to your practice range, the local ball field, schoolyard or anywhere you can safely hit golf balls 20-30 yards or less.
  2. Pick a target only 30-50 feet away and hit your normal pitch, observing the trajectory.
  3. Then try to hit each successive ball no further, but using a longer, more flowing, fluid swing motion than the one before. That means you’ll make the downswing slower and slower each time, as you are moving the club further and further back each time.

My bet is that somewhere in there you will find a swing length and tempo where that short pitch shot becomes much easier to hit, with better loft and spin, than your normal method.

The key to this is to move the club with the back and through rotation of your body core, not just your arms and hands. This allows you to control tempo and applied power with the big muscles, for more consistency.

Try this and share with all of us if it doesn’t open your eyes to a different way of short game success.

The Wedge Guy: The core cause of bad shots

Published

on

You are cruising through a round of golf, hitting it pretty good and then you somehow just hit an absolutely terrible shot? This isn’t a problem unique to recreational golfers trying to break 80, 90, or 100 — even the best tour professionals occasionally hit a shot that is just amazingly horrible, given their advanced skill levels.

It happens to all of us — some more frequently than others — but I’m convinced the cause is the same. I call it “getting sloppy.”

So, what do I mean by that?

Well, there was a USGA advertising campaign a while back feature Arnold Palmer, with the slogan “Swing Your Swing.” There’s a lot of truth to that advice, as we all have a swing that has — either frequently or occasionally – produced outstanding golf shots. While there is no substitute for solid mechanics and technique, I’ve always believed that if you have ever hit a truly nice golf shot, then your swing has the capacity to repeat that result more frequently than you experience.

The big question is: “Why can’t I do that more often?”

And the answer is: Because you don’t approach every shot with the same care and caution that you exhibit when your best shots are executed.

To strike a golf ball perfectly, the moon and stars have to be aligned, regardless of what your swing looks like. Your set-up position must be right. Your posture and alignment have to be spot-on. Ball position has to be precisely perfect. To get those things correct takes focused attention to each detail. But the good news is that doing so only takes a few seconds of your time before each shot.

But I know from my own experience, the big “disrupter” is not having your mind right before you begin your swing. And that affects all of these pre-shot fundamentals as well as the physical execution of your swing.
Did you begin your pre-shot approach with a vivid picture of the shot you are trying to hit? Is your mind cleared from what might have happened on the last shot or the last hole? Are you free from the stress of this crazy game, where previous bad shots cause us to tighten up and not have our mind free and ready for the next shot? All those things affect your ability to get things right before you start your swing . . . and get in the way of “swinging your swing.”

So, now that I’ve outlined the problem, what’s the solution?

Let me offer you some ideas that you might incorporate into your own routine for every shot, so that you can get more positive results from whatever golf swing skills you might have.

Clear your mind. Whatever has happened in the round of golf to this point is history. Forget it. This next shot is all that matters. So, clear that history of prior shots and sharpen your focus to the shot at hand.

Be precise in your fundamentals. Set-up, posture, alignment and ball position are crucial to delivering your best swing. Pay special attention to all of these basics for EVERY shot you hit, from drives to putts.

Take Dead Aim. That was maybe the most repeated and sage advice from Harvey Penick’s “Little Red Book”. And it may be the most valuable advice ever. Poor alignment and aim sets the stage for bad shots, as “your swing” cannot be executed if you are pointed incorrectly.

See it, feel it, trust it. Another piece of great advice from the book and movie, “Golf’s Sacred Journey: Seven Days In Utopia”, by Dr. David Cook. Your body has to have a clear picture of the shot you want to execute in order to produce the sequence of movements to do that.

Check your grip pressure and GO. The stress of golf too often causes us to grip the club too tightly. And that is a swing killer. Right before you begin your swing, focus your mind on your grip pressure to make sure it isn’t tighter than your normal pressure.

It’s highly advisable to make these five steps central to your pre-shot routine, but especially so if you get into a bad stretch of shots. You can change things when that happens, but it just takes a little work to get back to the basics.

Stickney: To stack or not to stack at impact?

Published

on

As you look at the impact positions of the best players in the world, you will find many different “looks” with respect to their body and club positions. Some of these impact positions might even appear unique, but don’t be fooled. They all have one thing in common: preserving the players’ balance throughout the impact interval! In fact, if you are not in-balance, then you will lose power, consistency, and have trouble controlling your launch dynamics from shot to shot.

This balance is a necessary key to playing well and one area that can be easily understood with a few graphics shown on GEARS 3D. As you examine the photo in the featured image, you can see a few things:

  • The player on the left has “fallen” backwards through impact slightly moving his head out of the circle established at address
  • The player on the right is more stacked at impact — meaning that his chest, zipper and hands are all in the same place at the same time (within reason)
  • The player on the left has reached this same position in the swing with different segments of the body reaching the ball at different times
  • There will be a difference of impact shaft lean between the two players due to one player reaching impact “together” and the other shoving his hands more forward as he falls back
  • The player on the right is more “connected” through impact…won’t be the longest hitter but will be able to find the ball in the fairway more often
  • The player on the left is putting more pressure on the rear portion of the lower back which could have a potential for injury if he’s not careful

Now, obviously there are pro and cons to both positions. Overall, if you want to be consistent and in-balance more often that not, I would suggest you try your best to focus on being “stacked” when you hit the ball.

Let’s dive in a touch deeper to show you what happens physiologically on 3D when you fall back through impact and I think it will really drive the point home.

  • At address notice the Vertical Spine Number 96.2, this is showing us where the spine is positioned at address
  • You can see the head is in the center of the bubble

  • On the way to the top of the swing you can see that the spine has moved “away” from the target laterally a slight bit to 98 degrees
  • The head has dropped downward and has also moved laterally as well- more lean over the right leg to the top

Now here is where the problem comes in…as you work your way to the top, it’s ok of your head moves a touch laterally but in transition if it stays “back” while your hips run out from under you then you will begin to fall backwards on the way to your belt-high delivery position.

  • We can see at the delivery position that the spine has continued to fall backwards as the hips rotate out from under the upperbody
  • When this happens the hands will begin to push forward- dragging the handle into the impact zone
  • Whenever you have too much spin out and fall back the hands move forward to accommodate this motion and this reduces your Angle of Attack and decreases your dynamic loft at impact
  • This will cause balls to be hit on the decent of the club’s arc and reduce loft making shots come out lower than normal with a higher spin rate and that means shorter drives

Now let’s examine impact…

  • The player on the left has reached impact in a more disconnected fashion versus the player on the right as you compare the two
  • The player on the right has a shaft lean at impact that is less than a degree (.75) while the player on the left has a much more noticeable forward lean of the shaft thereby reducing dynamic loft at impact

  • The player on the left’s spine has moved from 96.2 to 112.9, a difference of 16.7 degrees while the player on the right has only moved back a few degrees. We know this because his head has stayed in the bubble we charted at address
  • The hips have run out from under the player on the left in the downswing and this causes the head to fall back more, the hands to push forward more, and the impact alignments of the club to be too much down with very little dynamic loft (as also shown in the photo below)

Whenever the hips turn out from under the upper body then you will tend to have a “falling back effect of the spine and a pushing forward of the hands” through impact.  Notice how the hips are radically more open on the player on the right versus the left- 27.91 versus 42.42 degrees.

So, now that we can see what happens when the hips spin out, you fall back, and you fail to be “stacked” at impact let’s show you a simple way you can do this at home to alleviate this issue.

  

  • A great drill to focus on being more stacked at impact is to make slow motion swings with the feeling that the upper portion of your arms stay glued to your chest
  • These shots will be full swings but only 20% of your total power because the goal here is connection which allows everything to reach impact together and in-balance
  • The second thought as you make these swings is to pay attention to your head, if you can focus on allowing it to stay “over the top of the ball” at impact you will find that it will stay put a touch more so than normal. Now this is not exactly how it works but it’s a good feeling nonetheless
  • Once you get the feeling at 20% speed work your way up to 50% speed and repeat the process. If you can do it here then you are ready to move up to full swings at top speed

Finally, don’t forget that every golfer’s hips will be open at impact and everyone’s head will fall back a touch — this is fine. Just don’t over-do it! Fix this and enjoy finding the ball in the fairway more often than not.
