Whenever I see an amateur player sizing up a lengthy putt, or one that features several awkward slows and borrows, my immediate reaction is to think that he or she has a very good chance of three-putting. Why? Because amateur players hardly ever practice these putts and as a result, have poor feel. They tend to hit at the putt as opposed to stroking it.

Great putters not only hole out regularly from within six feet of the hole - that vital scoring distance - but they also have great touch and feel for distance on long putts. They realize that their goal from say, 30 or 40 feet is simply to 'lag' the ball close enough to the hole to have reasonably simple second putt. If it goes in, that's a bonus. Keeping those three putts off the card is a must.

golfing touch

FIX NO.45
Improve your touch

There are several things youcan do to become a good lag putter mentally and physically. (1) On facing a putt upwards of, say, 40 feet, make the most of positive mental imagery - not only the line of the putt but also by visualizing a bigger final target. Imagine a circle with about a two-foot radius painted around the hole, and simply try to roll your approach putt within that circle. If you do, the longest putt you can have left will be two feet. (2) Be conscious that pure technique here on these lengthy putts is not a prerequisite for feel. Stand a little taller at address andencourage a long, free stroke back and through, and allow a little wrist action to help with acceleration. Your left wrist should, in fact, be a little cupped at the completion of the stroke.

(3) Practice long putts with your right hand only. This will give you the feeling of releasing the putter head. (4) Hit putts from one side of the practice green to the other, aiming to get each ball as close to the fringe as you can without ever going off the edge. (5) When confronted with a long lag putt on the course, take plenty of practice strokes to sense the stroke needed to execute the putt at hand. With these keys, you could surprise your friends with your new found touch on long putts.

Think back to the last time you three-putted. What let you down? Your accuracy, or your inability to stroke the ball the desired distance? I'm prepared to wager that nine times out of ten, it's the latter.

On any putt over, say, ten feet, getting the distance right is much more important than direction. Even a beginner can hit a putt reasonably close the right line, but the chances of him rolling the ball the right distance are slim. Without the experience of 'fee', he's much more likely to rap the putt miles past, or leace the ball woefully short of the hole.

To a much lesser extent, the same is true of more advanced players. Many golfers have a tendency to hit a putt 'hard' or 'soft' depending on its length. That's asking for trouble. The 'hard' and 'soft' approach is too difficult to judge; you'll never develop a consistent feel for distance. And without that, you'll always be leaving your first putt too far from the hole to be sure of getting the next one in.

putting stroke

FIX NO.44
Longer putt, longer stroke

One of the golden rules in putting is that the length of your stroke should always control the distance you hit the ball. A relatively long putt requires a relatively long stroke, and vice versa. But there's a clause that you must adhere to: no matter what the length of the putt, your tempo - that is, the time it takes to complete your stroke - should remain constant. Thus, the pace of your stroke on a short putt will appear appreciably slower than that on a longer putt.

Good putters who seem to regularly hit their putts the proper distance have great tempo. With this in mind, practice putting to random targets to increase your awareness for the length of your stroke. Place tees in the green at distances of 10, 20 and 30 feet from your ball, and hit putts to all three, varying the length of your backswing for each, and making your follow-through at least as long - if not longer - than your backswing.

Always try to hit a putt firmly enough that, should it miss, the ball will finish about 18 inches past the hole. That's the optimum speed for the ball to hold its line, yet still fall in if catches any part of the cup.

Finally, be aware that you must take into account the condition of the green and the nature of your putt - ie. uphill or downhill - when determining speed.

Nothing ruins the consistency of a putting stroke like unwanted wrist action through impact. This breakdown can often be seen to occur in conjunction with a shoulder motion that has either stopped or is decelerating, and is one of the most common causes of a poorly struck short or medium length putt - and this applies equally to the pros. With this fault, judging the pace and controlling the direction of your putts can prove to be a real problem. Because of the uncertainty that surrounds this type of wrist action in terms of the strike you impart on the ball, rarely will you release the putter with any confidence. You end up decelerating the putter through impact, which makes it virtually impossible to put a good roll on the ball.

putting pull and push

FIX NO.43
'Pull' and 'Push'

To help protect yourself against any unwanted hinging in the left wrist, hold the putter so that the shaft runs high across the palm of your left hand, resting against the fleshy pad below the thumb. Then close your hand, draping your left index finger over the fingers of your right hand. Doing this forms what's known as the 'reverse-overlap' grip; the left hand is now effectively locked in place on the club.

Now let's put your grip to the test. Remember, in a solid pendulum stroke, the shoulders control the motion from start to finish while the hands remain passive. Try this drill: address a straight three-foot putt, and without a backswing, 'brush' the ball towards the hole. Make the follow-through by 'pulling' with your left arm and left shoulder and 'pushing' with your right arm and right shoulder. Focus on keeping your left hand firm as you accelerate the putter past your left foot, and check to see that the putter-face is looking directly at the hole on the finish.Repeating this drill regularly will give you the correct feel, eliminates the 'wristiness' in your stroke, and should get those putts dropping.

Putting - poor distance control

Holing putts on a regular basis is all about having the putter-face square to the intended line at the moment it contacts the ball. To do this, most good putters predominantly use a pendulum-like, arm-and-shoulder action, in which the triangle that is formed between the arms and shoulders at address can be seen to remain intact as it moves past a steady head. In other words, there is little wasted motion.

Putting problems aris when you try to 'help' the ball into the hole. WHen that happens, your head and upper body tend to move out of position through impact, which inevitably disrupts the alignment of the putter-face. The result is an inconsistent strike on the ball, and little or no control over the direction or the pace of the putt.

FIX NO.42
Rock your shoulders to control your stroke

In putting, the fewer moving parts there are , the simpler and more consistent your method will probably be. To that end, I encourage you to work on building a stroke that is controlled by the shoulders.

To promote this pendulum-type action, try the following exercise. Take your address position, and place your palms together in a downward praying position. Focus on the triangle that is formed between your hands, arms and shoulders, and then, keeping your head and lower body perfectly still, rock your shoulders so that you move the triangle smoothly back and through

(1). Create an under-and-up pendulum motion with your shoulders, where your chest stays square to the target line, as opposed to opening your body to the hole. Feel that your left shoulder works down on the backswing, then up on the throughswing. This will control the path of the putter-head and keep the putter on line through impact

(2). On the follow-through - particularly on the longer putts - allow your head to rotate down the line towards the target after you have completed your stroke. That enables your triangle to work correctly, and thus allows you to follow the progress of the ball all the way to the hole without lifting your body out of position.

By its very nature, putting is a hugely personal matter. But whatever style you choose to trust on the greens, I believe it's important that you develop the ability to repeat a stroke which produces overspin; one which guarantees a consistent roll on the ball. Naturally, the quality of your address position has a direct bearing on your ability to achieve this. The way you set up dictates how easily your arms and upper body are able to work together, which in turn determines the path of your stroke and the position of the putter-face at impact.

There are two common faults that I see. First, there's the example of the player who stands very tall at address, with his legs stiff, his arms straight and his eyes outside the ball-to-taarget line (1). Then there's the player who does just the opposite; he tends to sit down too much, his elbows are usually very bent, and his eyes too far inside the ball-to-target line (2). Neither of these positions does much to encourage a uniform stroke. The arms and hands tend to work independently, rather than as a single unit in tandem with the chest and sholders.

rock-steady stroke

FIX NO.41
Get set for a rock-steady stroke

I believe that the shoulder-controlled, pendulum-type stroke is the most effective for consistent putting. But for this method to work, your posture must allow your arms complete freedom of movement.

Let's build it from the ground up. In front of a mirror, take a comfortably wide stance, and flex your knees a little, as if you were just about to sit down.Feel that your weight favours your left sie a touch, and keep your elbows relaxed and spread to the point where your upper arms rest lightly on your rib cage (1). Your eyes should be directly over - or very slightly inside - the ball-to-target line; the ball itself should be opposite your left eye. (Quick check: test yourself by dropping a ball from your left eye, and noting where it lands.)

Next, your alignment. Following the example that we set in the full swing, aim the putter-face squarely to your target line, and then try to align your body parts - ie. your feet, knees, hips, forearms, shoulders and eyes - parallel to it (2). As long as you stay relaxed, your hands comfortably positioned either in line with, or slightly ahead of the ball (and directly beneath your shoulders), you are now in the perfect position to make a smooth stroke in which your bands, arms and shoulders work together.

1: Posture & Set-up

2. The blade of the putter needs to be square at address and at the strike position. If somebody addresses the ball with the blade open and / or closed and they say ‘But I always hit it online…’ but when the pressure’s on, it doesn’t work, they are vulnerable

3. The blade of the putter needs to be square to the path of the stroke through the hitting area. In other words, you don’t want to put a slice or hook spin on the ball, because if you do, on its first contact with the ground, the ball will endeavour to spin just like an off-break or a leg break in cricket… It may only be a minute amount of spin, but it will be sufficient to cause the ball to track off the intended line of putt.

4. It is crucially important that the ball is struck with a slight upstroke, so that when you strike it you create forward roll on the ball. That can be achieved but have the ball in the perfect position and having the right plane of strike as you hit the ball. There’s no magic secret to it… roll the golf ball!



5. Every putt is a straight putt, but it depends on how hard you hit it, whether or not it takes any break that you may read into the green. To achieve the desired result one needs an ideal, smooth acceleration, not deceleration, through the ball.

Rapid Acceleration (short backswing)

• Speed at impact 1.75 msֿ¹
• Max speed 2.11 msֿ¹
• 0.06 seconds AFTER impact
• Poor distance control

Deceleration of putter through impact (long backswing – short follow through)

• Poor distance control
• End up quitting on the stroke
• Speed at impact 1.63 msֿ¹
• Max speed msֿ¹
• 0.08 seconds BEFORE impact!

It is very difficult to control the putter head (open or closed) with a blade that is slowing down…

Constant speed at impact: No acceleration (Backswing 48% & Follow through 52%)

• Constant speed = Good rhythm
• Speed at impact 1.84 msֿ¹
• Max speed 1.86 msֿ¹
• 0.025 Seconds AFTER impact
• Constant speed at IMPACT = great distance control

PREPARE:  BEFORE YOU PLAY – LINE UP YOUR BALL

You will have seen many, if not all Tour Professionals, have a line drawn on their golf ball which assists them when lining up putts. This line is put on with a permanent marker (sharpies seem to be the best) and you either attempt to draw the line yourself or use a “Line them up tool” which makes life a lot easier.

GET THE BIGGER PICTURE

As you approach the green, take a mental note of its general shape. Is it sloping toward your ball? Away from it? Does the green fall off on one side? These larger features will take priority over smaller breaks when determining how your ball will roll. Keep a close eye on what your approach shot did when it rolled on the green, this will also help when deciding on the break your putt might take.

SPEED

Check from all sides to see if the putt is uphill or downhill. Simply walking up and down the length of the put will enable you to fell the undulations of the green under your feet.

BREAK

Once you have a pretty good idea of the speed of the putt, squat down behind your ball with your eyes as level as possible. Look from your ball to the hole and determine which side of your line is the high side and which side is the low side. After you’ve determined which side is high and which is low, walk over to the low side (the direction toward which the ball will curve) and take a look up the slope. This will give you a much better idea of the severity of the slope than just looking from your ball to the hole. Keep in mind that break is more important the closer you get to the hole, because your ball will be traveling more slowly and thus will be more affected by the break as it nears the cup.

LINE UP YOUR BALL

Once you have decided on the break of your putt pick out a spot about four feet in front of your ball that is on the line you think the ball is going to take.
Position your ball, with the line you put on it earlier, pointing directly at the spot you have chosen. Align your putter at right angles to the line on the ball which means you will now be aiming exactly on the line you have chosen

VISUALISE

Now that you’ve determined the distance, speed and break of your putt, create a picture of your ball rolling to and falling into the hole. On left-to-right putts, the ball must enter the hole left of center, and on right-to-left putts the ball must enter right of center. Speed determines direction, so on a downhill putt, you need to hit the ball softer, which means the ball will be more affected by the break. On an uphill putt, you need to hit the ball harder, which means that your ball will be less affected by the break. A few practice swings visualising the ball rolling into the hole are invaluable.

HOLD THE FINISH

After your stroke is completed hold the posture and position of the follow through, and  keep looking down until the ball is well on its way. Looking up too early is not going to help you in any way. Most putts are missed through moving the body out of position through the stroke so stay down and hold that follow through. On most short putts Professionals don’t even see the ball drop into the hole but instead wait till they hear it hitting the bottom of the cup.

Best of luck with your putting

Best (and simplest) Putting Tip Ever

All putting strokes are different, there is so much creativity and imagination required in putting that it’s very rare you’ll ever see two putting strokes that are the same.

However, there is one commonality between all goodamateur putters and ALL PGA Tour Players.

This one common aspect of all good putting strokes is so simple and so effective, you’ll be amazed at the difference when you’re consciously making sure it happens.

 

Different Strokes

Some putting strokes go inside out.

Some putting strokes go outside in.

Some have a pop stroke.

Some are so smooth that it appears as though the ball is simply, getting in the way.

Some are sure to make their follow through the exact same distance as their take away.

Some have a short take away and a long follow through.

Some keep their hands high.

Some have hands low with the toe facing up.

Some have a back and through that goes on an a semi-circle.

Some keep the putter head straight back and straight through.

Some come through a putt like a pendulum with the head high on take away and on follow through.

Some use a forward press.

You get the idea and you can agree there are a million ways to skin the putting cat in terms of mechanics.

putting tip keep head stillSo, what is the commonality that makes every great putter, a great putter?

It doesn’t matter if you’re a feel putter that can visualize the line and imagine the perfect speed or if you prefer to putt the analytical way and putt to a point on the green.

Jack Nicklaus putted almost side saddle, arms out, hunched over, with an open stance and a pop stroke.

Tiger is far more upright with a smooth “ball got in the way” motion and arms in tight.

Many players are simply so developed in the area of reading greens that the mechanical aspect is completely secondary and they could use a 2 x 4 to get the job done.

None of the great putters, none of the good putters, nobody who takes their putting stroke seriously…ever PEEKS.

If you want to get better at putting, keep your head still, very still.

Get your eyes over the ball and the putter head then… leave it there until the ball is at least half way to the cup.

Test This Out

Next time your on the practice green, take ten putts with your normal stroke.

Then go back to the exact same spot and hit ten more, with dedicated concentration on not moving your head.

Pick a point directly behind the ball on the green, between the putter head and the ball. As you take the putter head away, keep your eye on the back of the ball and the tiny spot you picked on the green.

Concentrate on leaving your eye, and subsequently your head, completely still after contact.

Don’t move it until you know for sure the ball is at least 4 feet away.

You’ll be amazed at the results.

What it does is pretty simple. It keeps your body rock solid and that causes you to make pure contact with the ball at a much higher rate.

Pure contact is the key to hitting great putts.

When you’re peeking up to watch the ball leave, even in the slightest, your hands and wrists will subconsciously react and cause poor contact.

Peeking will also cause you to push putts off line.

So Simple

I know it sounds too simple and everyone thinks they are keeping their head still but, most are not.

Watch people closely as they putt and you will see below average putters always pop those eyes up to take a look at the ball as it’s leaving the putter head.

Don’t make any judgments about this little drill until you have had the chance to try it out.

Don’t just assume you are keeping your head still now, go try it out while making a few putts and you’ll feel the difference.

Eyes over the ball

Head completely still

Back of the front hand aimed at the target all the way back and all the way through

Head remains still

Good luck, roll’em pure and straight!

The perfect putt is a simple pendulum driven at twice its resonant frequency.

KFC 03/13/2009

  • 3 COMMENTS

Watch professional golfers putt and you'll eventually notice three common features about their style, says Robert Grober, an expert on the physics of golf at the Yale University.

First, the putter head always moves at a constant speed when it hits the ball. Second, the length of time the putting stroke takes has little impact on the speed of the ball (and therefore the length of the putt). And finally, a professional golfer's backswing takes about twice as long as the downswing.

Grober has used these observations to construct a mathematical model of a putting swing and to explore other properties of such a system.

It turns out that the model that best accounts for this behaviour is a simple pendulum driven at twice its resonant frequency.

That explains a number of other observations about professional golfers, says Grober. For example, a common putting tip is that longer backswings equate to longer putts. This model has exactly this characteristic: the length of the backswing is proportional to the speed of the club at impact.

It is also relatively straightforward to get a sense of the tempo of the required putt by swinging the club back and forth in resonance, like a pendulum. The duration of the actual stroke is exactly half the length of the putter cycle (i.e. from the address position moving backward, to the address position moving forward). "In fact, one often observes golfers instinctively doing this before they hit a putt," says Grober.

So now the secret is out. Make a careful note for next time you're out on the links.
