Here’s how to stop slicing a golf ball: start with your grip, then check the path your club travels through the ball. A slice curves to the right for a right-handed golfer, so the ball starts out and bends away from you. Your grip directly affects clubface control, and ultimately your ball flight [1].
The quick fix is a grip adjustment that keeps the clubface from opening at impact, and it’s the first thing to try because it costs nothing but a few minutes on the range. If the ball still curves, the next suspect is your swing path. An important element to fixing a slice is the direction the club is swinging, so you want to focus on an inside-out club path [2].
This article works through the causes in order: grip first, then path, then how your shoulders can pull the club off plane. Change one thing at a time, so you know which change actually helped your ball flight.
Is your grip setting the clubface open?
Your grip has a direct effect on how the clubface moves at impact, and the clubface controls your ball flight [1]. If the ball keeps curving right, the grip is the first thing to check because it is the quickest place to make a change.
The main point is that your hands should not be turned too far on the club, and the left hand matters most [1]. A grip that is turned too far around the shaft gives the face a different angle at impact, so the ball starts and curves in a different way. You are not looking for a new grip, only a small adjustment to the one you have. You may also find this useful: How to Grip a Golf Club for Beginners: Hands, Pressure and Faults.
Here is a simple hand check you can do at the range:
Take your normal address position with a mid-iron and look down at your left hand.
Notice whether the hand sits turned far around the grip, toward the right side of the club for a right-handed golfer.
Rotate the left hand back toward a more neutral position, then hit a few slow swings with the new feel.
Watch where the ball starts. If it starts farther left of your old starting line and curves less, the change is working.
Do not force the change with your wrists. Move only the left hand, keep your right hand where it was, and hit a bucket of balls before you decide whether it helped.
A simple grip change can help eliminate a slice and start you hitting more powerful draws [1]. Keep it as your first test, and move on to your swing path only if the ball still curves the same way.
Are you swinging across the ball from outside to in?
An outside-in path means the club comes down from outside the target line, cuts across the ball, and finishes pointing left of your target for a right-handed golfer. That across-the-ball motion adds sidespin, which is why the ball curves right. Picture the club swinging across your body instead of through the ball.
An important element to fixing a slice is the direction the club is swinging. [2] You should focus on swinging with an inside-out club path. [2] In practice, that means the club drops down inside the target line on the way down, then sweeps out toward the target after impact.
The change is about direction, not power. Swinging harder on an outside-in path usually sends the ball farther right, so a smaller, slower swing lets you work on the path first. If your shots start right of a flag down the fairway and keep curling right, the club is probably still coming from outside.
Here is a feel cue to try on the range. On a slow practice swing, let your hands start the downswing by pulling the club down toward your back pocket, as if you are dropping it behind your hip line. Then swing through toward the target and let the club finish out past your belt buckle.
Hit ten balls with that feel and watch the start line. You should see the ball leave closer to your target line and curve less than before.
Does your upper body pull the club off plane?
Your shoulders set the club’s path on the way down, so a slice often starts when they get left out of the swing. If your arms and hands take over and pull the club away from the line, the club tends to come over the top and cut across the ball. Turning your shoulders keeps the club moving on a path you can repeat.
The fix is to turn your shoulders back and feel the weight of the clubhead, keeping it on the shallower plane you’ve established. [3] A shallower plane means the club sits flatter on the way down, so it approaches the ball from inside the target line instead of dropping steeply from above. That is the feeling you want as you start the downswing.
For a weekend player, the easiest way to feel this is a slow half swing. Make a backswing with a smooth shoulder turn and let your arms hang loosely. Then turn through to a balanced finish, swinging at about three-quarters speed so you can notice where the clubhead travels.
Keep your grip and arms relaxed rather than forced. When your shoulders lead, your hands have less reason to grab at the ball, and the club stays on a path that is easier to repeat.
What should you try first, second and third?
Start with your grip, then your path, then your shoulder turn, and change only one of them at a time. That way you can tell which change actually straightened the ball flight.
Check and adjust the grip. Look at how your hands sit on the club before you swing. Your grip sets the clubface, and to control it, your hands should not be turned too much on the club, with the focus on the left hand. [1] Make one small change to your left hand, then hit a few balls and note the flight before you touch anything else.
Work on an inside-out path with a slow swing. Next, focus on the direction the club travels. You should swing with an inside-out club path, so the club comes in from inside the target line instead of across it. [2] Picture a line from your ball to the target and let the club approach from just inside that line. Slow the swing down so you can feel that path instead of muscling the club over the top. Hit a few balls at half speed and watch where they start.
Turn the shoulders and feel the shallower plane. Once the path feels better, turn your shoulders back and feel the weight of the clubhead. [3] Keep the club on a shallower plane, so it swings more around your body than straight up and down. Let your shoulders turn rather than pulling the club off line on the way down.
Keep to this order, and do not add the next change until the last one feels natural. Trying all three at once makes it impossible to know which fix worked.
When should you pay a pro for lessons?
If the slice keeps showing up after you have worked through the grip, path and shoulder fixes, it is time to book a lesson with a teaching pro. A pro can watch your swing from several angles and tell you which cause is really driving the curve. That saves you from guessing at it for weeks.
Why a pro can see what you cannot
From the inside, a swing feels very different from how it looks on video. You may think you are swinging from the inside while your club is actually coming across the ball. A teaching pro can watch your swing and confirm the cause, so you are not chasing the wrong fix.
A pro can also check things you cannot easily check yourself, like your clubface at impact and where your club enters the swing. Within one session, they can often tell you whether the grip, the path or the upper body is the main problem.
When the steps are not enough
A slice that persists after you have changed one thing at a time over several range sessions is a good reason to book a lesson. Give the steps a fair try first. If you have worked on your grip, practiced a slow inside-out path and tried turning your shoulders, and the ball still curves hard to the right, you have good information to bring to a pro.
Bring a short summary of what you tried and what the ball did. For example, say the ball starts on target and then curves 20 yards right, and that the grip change did not help. That gives the pro a clear starting point.
Weighing the cost
Lessons cost money, and not every slice needs one. Many weekend players fix a slice on their own with a few focused range sessions. A single lesson can still be worth it if it saves you months of frustration and a pile of wasted range balls.
Ask the pro what they will watch and what you will practice afterward. A good teacher will explain the cause in plain words and give you one or two things to work on, not a long list of changes at once.
Where should you start on your next range visit?
Start with the grip, then the path, then the shoulders, and work on only one of them in each practice session. That order matters because the grip sets the clubface, the path sets the direction the club travels, and the shoulders control how the club moves on the way down. Fixing them in that sequence keeps you from chasing three problems at once.
When you go to the range, pick one thing from the list and spend the whole session on it. Hit a basket of balls, check the ball flight, and only then decide whether the change worked. If you switch between grip, path and shoulders every few swings, you will not know which change helped, and you will likely end up more confused than when you started.
Your next step is simple: on your next range visit, begin with a grip check, make one small adjustment, and hit 20 to 30 balls with that single change in mind. Once the ball starts flying straighter, you can move on to the path, and then the shoulders.
