That banana-shaped shot that sails helplessly into the right-hand rough isn’t just adding strokes to your card, it’s one of golf's most persistent and frustrating problems. But here’s the good news: a slice is almost always caused by the same two swing flaws, and both are entirely fixable. This guide will walk you through understanding exactly why you slice and give you a series of practical, step-by-step adjustments and drills to finally straighten out your ball flight for good.

First, Let's Understand the Slice
Before we can fix the problem, we need to know exactly what’s causing it. At its core, a golf slice is a simple matter of physics. It's the result of two things happening at the moment of impact:
An 'out-to-in' swing path. This means your club head is traveling from outside your target line to inside your target line as it strikes the ball. Imagine two railway tracks leading to your target, an out-to-in path means the club is crossing those tracks from right to left (for a right-handed golfer).
An open clubface. This means that at the moment of impact, your clubface is pointing to the right of your swing path.
When you combine these two things - an out-to-in path and an open face - you put "slice spin" on the golf ball. It's the same kind of side-spin a tennis player uses to curve a serve out wide. The ball starts left of the target (because that’s where the path is going) and then curves dramatically to the right (because that’s where the face is pointing). Fixing the slice is all about correcting these two fundamental issues. We will start with the easiest fixes first: the setup.

Ask Caddie anything. From “what club should I use?” to “how do I play this shot?” and get instant answers.
More often than not, the slice begins before you even start your swing. Your setup dictates a huge portion of what will happen over the next 1.5 seconds. If you set up for a slice, you’ll probably hit a slice.
Check Your Grip: The Steering Wheel of Your Golf Shot
Your grip is the single connection you have with the club, and it's the primary factor in an open or closed clubface. The most common cause of a slice is a "weak" grip, which means your lead hand (the left hand for a righty) is rotated too far to the left, underneath the club. From this position, the club naturally wants to open during the swing. A slice is almost inevitable.
Here’s how to build a stronger, more neutral grip:
Hold the club out in front of you. Let your left arm hang naturally at your side, and then bring your hand to the grip.
Place the grip in the fingers of your left hand, primarily from the base of your pinky to the middle joint of your index finger.
Now, close your hand. When you look down, you should be able to see at least two knuckles on your left hand. Many slicers only see one, or even none.
The "V" formed by your thumb and index finger should point towards your trail shoulder (your right shoulder).
Bring your right hand to the club, letting the "V" formed by your right thumb and index finger point to your right shoulder also. Rest your right palm over your left thumb and your fingers wrap around. This puts your hands in a powerful, unified position, ready to deliver a square clubface.
Heads Up: If you've been playing with a weak grip for a while, this new position will feel incredibly strange and "closed." Trust it. Your brain is used to the old feeling. It takes repetitions for this new, better grip to feel normal.
Check Your Alignment: A Common Mental Trap
Here’s a paradox many slicers fall into: because they see their ball go right, they start aiming their bodies further and further left to compensate. You might think this helps, but you're actually making the slice worse. When you aim your body left while the clubface points at the target, you are pre-setting an out-to-in swing path. From there, you have no choice but to come "over the top" of the ball, all but guaranteeing a slice.
Get back to basics on the range:
Place an alignment stick (or another golf club) on the ground, pointing directly at your target. This is your target line.
Place a second alignment stick parallel to the first one, just inside closer to you. Your feet, hips, and shoulders should be square to this second stick.
This simple setup ensures your body is aligned parallel to your target line, promoting a swing path that moves down the line towards the target, not across it.
Fix #2: Re-Route Your Swing Path
With a solid setup, you have laid the groundwork to fix your swing path. Now it's time to tackle the root motion of the slice: the infamous "over-the-top" move.
The Backswing: Getting into the "Slot"
A slice often originates from a very early mistake in the backswing: golfers tend to lift the club too steeply or whip it flat and inside too quickly. We need a connected, one-piece takeaway to get the club in the right place at the top.
The goal: Feel your arms, hands, chest, and club move away from the ball together as one unit. The first move should be turning your torso.
A great checkpoint: When the club shaft is parallel to the ground in the takeaway, the clubhead should be hiding your hands, or slightly outside of them. If you can see the clubhead is way inside your hands, you’ve pulled it inside too early and are setting yourself up for an over-the-top move on the way down.
The Transition: The Secret to an Inside Path
This is the moment of truth. An "over-the-top" move happens when the first parts to move from the top of the swing are your shoulders and arms, throwing the club outside the target line. To fix this, you have to retrain your swing sequence.
The feel: Great swings start the downswing from the ground up. Before your shoulders even think about turning, you should feel a slight bump of your hips toward the target. It's a small lateral shift that gets your weight moving forward and gives your arms the space to "drop" the club into the "slot" - down onto an inside plane.
Think about this: At the top of your swing, feel as if your back stays facing the target for a split second longer while your lower body begins to unwind. It's a feeling of patience at the top. This feeling prevents your shoulders from spinning out early and throwing the club over the top.

Talking about swing mechanics is one thing, feeling it is another. These drills are designed to exaggerate the feeling of an in-to-out swing path. Spend time with them on the range, and the motion will start to feel natural.
Drill 1: The Trail Foot Back Drill
This is one of the simplest and most effective drills to feel an "inside path."
Set up to the ball as you normally would.
Now, take your trail foot (your right foot for a right-hander) and drop it straight back about six inches to a foot. Your feet are now in a very "closed" stance.
From here, just try to hit the ball. This stance physically restricts you from spinning your hips open too early and makes it far more natural to drop the club to the inside. You’ll instinctively swing more from the inside-out. Hit 10-15 balls this way, then step back to a normal stance and try to recreate that same feeling.
Drill 2: The Headcover Drill
This provides powerful visual feedback to prevent an over-the-top path.
Place the ball down to be hit.
Place your driver's headcover (or an empty box of balls) on the ground about one foot outside of your target line and one foot in front of the ball.
Your goal is to hit the ball without hitting the headcover. If you come over the top, you'll clip the headcover every single time. To miss it, you have to approach the ball from the inside. Start with slow, half-swings until you can consistently miss the headcover, then gradually build up your speed.
Drill 3: The Pump Drill
This drill trains the correct downswing sequence (hips first, then torso, then arms).
From the top, make a slow-motion rehearsal of the first part of the downswing. Initiate it by bumping your hips forward, letting your arms drop just to about waist high. Then pause.
Go from that halfway-down position back up to the top of your backswing.
On the third and final "pump," continue down and swing through to hit the ball.
