How to Fix a Slice

Here is the good news before we start. The slice is the most common shot in all of recreational golf. More than 70% of amateurs fight it. So if your ball keeps sailing right into the trees, you are not broken and you are not alone. You are simply in the biggest club in golf, and it is a club you can leave whenever you like.

In the Netherlands this matters early. Most beginners at the driving range develop a slice before they ever get their GVB and their baanpermissie. To play a real course near Utrecht you need to show basic ball control. So fixing the slice is not only about pretty shots. It is your ticket onto the course.

What actually causes a golf slice?

The clubface. Launch-monitor data from TrackMan shows the face angle at impact decides roughly 75 to 85% of where the ball starts, and the face relative to your path decides the curve. When the face is open to the path, you slice. It is the same spin that makes a baseball curve.

GOLFTEC studied 14 million real swings and found three main causes: an open face-to-path relationship, hips that do not turn enough, and a downswing that comes in too steep. Notice that only one is about the face. Two are about your body and your path. Keep that in mind, because it changes the fix.

Why do beginners almost always slice — and why do instincts make it worse?

The ball flies right, so your brain says: aim left. This feels smart. It is the exact wrong move.

Aiming your body left tilts your whole swing more across the ball, from outside to inside. That steeper path adds more slice spin, not less. A lot of new golfers tell me the same story. They aim ten, twenty meters left, the ball curves even harder, and they decide their swing is hopeless. The swing was fine. The aim was feeding the slice. One golfer wrote about twenty years of this, buying driver after driver, almost losing his love for the game, until he understood his own instinct was the enemy.

The real cure is an inside-out path. For a right-hander that feels like swinging out to the right, toward first base. Strange, yes. But that “wrong” feeling is exactly right.

How do you fix your grip to stop the slice?

Start with your hands, because a weak grip makes squaring the face almost impossible. A weak grip means your hands are rotated too far toward the target.

Set your grip so you can see two or three knuckles of your lead hand when you look down at address. That small turn lets the face close through the ball. And soften your hold. On a scale of one to ten, grip at about three or four, never squeezing. A light grip lets the clubhead swing free and the face release naturally through impact. This tiny change alone straightens many players. A good grip is the base of everything, so it is worth reading my full page on grip, stance and posture too.

Why does the driver slice so much more than your irons?

The driver punishes an open face like no other club. It has the least loft, so almost all the spin goes sideways instead of up. It has the longest shaft, so the face is harder to control. And you hit it on the way up off a tee, which exaggerates any open tendency.

Your irons are kinder. You stand closer, the shaft is shorter and easier to manage, and the extra loft turns some of that sidespin into backspin. This is why many golfers hit decent irons but slice the driver into the next fairway. If your driver has an adjustable hosel, a “draw” setting can quiet the spin while you work. But the club is a helper, not a fix. One golfer described buying more and more expensive drivers, only to watch each one do the same thing. The slice just cost more money.

Which drills fix a slice fast — and what should the swing feel like?

Train the path, and the face follows. Three drills I trust:

• Headcover drill. Put a headcover six to eight inches behind the ball, just outside your target line. Swing so the club passes under and inside it. This blocks the over-the-top move where the right shoulder throws out toward the ball.
• Extra-ball drill (a favourite of Dutch instructors on golf.nl). Place a spare ball slightly behind and to the right of your real ball. To miss it, you must swing from the inside. Your body learns the new path by itself.
• Towel drill. Tuck a small towel under your lead armpit and keep it there through half-swings. It teaches your arms and chest to turn together instead of casting the club out.

For a feel, borrow the Dutch cue laag naar hoog, low to high. Low and around in the backswing, high through the finish. It flattens your plane and invites that inside-out strike.

And do not be shy about exaggerating. Swing so far to the right that you hit a little hook. That is a real teaching trick. The over-correction resets your sense of neutral, so a straight ball becomes your new normal.

How long does it take to stop slicing for good?

Faster than you fear. Most golfers see a straighter flight within a few focused sessions. In one to two weeks of real practice the slice usually calms right down. To fully own the change under pressure on the course, give it several weeks to a few months. Small steps. Small steps win in golf.

When is it time to book a lesson instead of self-diagnosing?

When you have tried the grip and the drills and the ball still curves, a good pair of eyes saves you months. Sometimes the cause is not technique at all. I have seen slices that came from limited shoulder mobility, where the player slid forward instead of turning and made the steep path almost mechanically. A video and a lesson find that in minutes.

I teach this every week at Chi Chi Golf in Utrecht and at Hoenderdaal in Driebergen, and watching a slicer hit their first straight drive is one of my favourite moments in golf. You can see what lessons cost on the pricing page, or read the sister guides on fixing a hook and stopping fat and thin shots if those creep in too. When the weather turns, my winter indoor drills keep your new path fresh.

Come play a straight ball with me. I promise it feels wonderful.
