Nothing feels quite as frustrating as taking a confident swing, only to watch a massive clump of turf fly further than your golf ball. That dreaded, jarring sensation of the duff or chunk can stall a great round and shake your confidence to its core. This article will explain exactly why you’re duffing your shots and, more importantly, give you a straightforward, step-by-step plan to eliminate it from your game for good and start making crisp, clean contact.
In simple terms, duffing a golf shot - also called hitting it “fat” or “chunky” - is when your golf club hits the ground before it makes contact with the golf ball. Instead of the club face striking the ball cleanly and then taking a nice, shallow divot after the ball, the clubhead digs into the earth behind it.
This does a few destructive things:
The result is a weak shot that travels a fraction of the intended distance. But here’s the good news: duffing isn’t a mystery. It’s a symptom of a very specific problem in your swing, and once you understand it, you can fix it.
At its heart, duffing all comes down to one thing: the low point of your golf swing is in the wrong place. Imagine your swing as a giant hula hoop circling around your body. The very bottom of that hoop is your "low point." For crisp iron shots, we want that low point to be a few inches in front of the golf ball.
When you duff a shot, the bottom of your swing arc is happening behind the ball. Your club reaches its absolute lowest point too early, causing it to dig into the ground first. Let’s look at the most common reasons why this happens.
This is probably the biggest culprit for amateur golfers. Remember, the golf swing is a rotational action. Think of your body turning in a barrel or cylinder. You want to rotate your hips and shoulders away from the ball in the backswing, and then unwind that rotation through the ball.
Swaying is when you slide your body laterally - away from the target - during your backswing. Your head moves, your hips slide, and your weight shifts too far onto your back foot.
The problem: If your entire body moves a foot behind the ball, that’s where the bottom of your swing wants to be. Getting all that weight and the swing's low point back to where it needs to be (in front of the ball) in the fraction of a second you have for a downswing is an athletic feat most of us can't pull off consistently. It's much easier to just leave the low point behind the ball, resulting in a duff.
During a good backswing, you create a powerful angle between your left arm and the golf club shaft - this is your wrist hinge. The goal is to maintain that angle for as long as possible in the downswing and "release" it right at the moment of impact. This is what creates that effortless "snap" or "whoosh" you hear from good players.
"Casting" is the exact opposite. It's when you throw that angle away from the top of your swing, using your hands and arms to try and force power. You essentially unhinge your wrists prematurely. This makes the clubhead get out in front of your hands, widening the swing arc way too soon. When the arc widens early, its lowest point naturally falls behind the golf ball. Result? Chunksville. Population: you.
This is closely related to swaying, but can also be its own issue. A proper downswing starts from the ground up. You should feel a slight shift of pressure into your front foot to begin the sequence, which helps pull the club down and move the low point forward. A key thought from our point of view on the swing is wanting to get 90% of your weight onto your lead foot at the finish.
Many golfers, however, do this beautiful body rotation on the backswing and then just unwind from the top using only their arms and upper body. Their weight hangs back on their trail foot. This not only robs you of power (your body is the engine, remember!) but it anchors the swing's low point firmly behind the ball. If your weight is back, your low point will be back.
Enough about the problem - let's fix it. Here's a practical, easy-to-follow guide with drills you can do at the range to start making pure contact immediately. Forget complex swing thoughts, we’re going to retrain your body to do the right thing naturally.
This is the most direct way to fix your low point and it gives you instant feedback.
If you duff it, you’ll see your divot or scuff mark start behind the line. If you hit it cleanly, the ball will be gone and your divot will start at, or just past, the line. This trains your brain to move the bottom of your swing forward.
To train rotation over swaying, you need some physical feedback.
A good finish position isn't just for looking good on camera, it's the result of doing everything correctly on the way there. If you make a great finish your goal, your body will figure out the downswing.
Eliminating the duffed shot is all about understanding and controlling the low point of your golf swing. By focusing on rotating your body instead of swaying, staying centered, and ensuring your weight gets to your front foot on the finish, you will automatically move that low point in front of the ball for pure, satisfying contact.
