The slice is the most common and most frustrating problem in amateur golf. If your ball curves dramatically to the right (for right-handed golfers) with a weak, fading trajectory, you’re not alone — estimates suggest that 70–80% of amateur golfers slice the ball at least occasionally, and for many, it’s a persistent problem that costs 5–10 strokes per round. The good news: the slice has well-understood mechanical causes, and once you understand what’s actually happening at impact, fixing it is more straightforward than most golfers realize.
This guide covers the exact causes of a slice, the most effective drills for each cause, quick in-round adjustments, and how to consolidate the fix so the changes stick. Whether you’re a beginner trying to hit the ball straight for the first time or an experienced golfer with a chronic fade that has become a full slice under pressure, there’s a solution here.
What Actually Causes a Slice?
The slice is caused by a specific combination of club face angle and swing path at impact. Understanding the physics is essential to fixing the shot — without it, you’re just guessing.
The Ball Flight Laws
Modern ball flight research (Trackman and other launch monitor data) has established what’s known as the New Ball Flight Laws. The ball starts roughly in the direction the club face is pointing at impact (about 80–85% face, 15–20% path). The ball then curves away from the swing path. For a slice: if the face is open relative to the path (pointing more right than the path direction), the ball will start slightly right but curve further right — a weak slice. If the face is very open relative to path, the ball will curve dramatically right from the start.
What this means practically: slicing is almost never about swing path alone. It’s about the relationship between club face and path. Many golfers who try to “fix their swing path” without addressing the face find that they just redirect their slice into a pull-slice. The face is the primary variable.
The Three Main Slice Causes
- Open club face at impact — The face is pointing right of target at the moment of contact. This is the most common cause and usually stems from a weak grip, an over-the-top swing path, or losing the wrist angles through impact.
- Out-to-in swing path — The club head is traveling from outside the target line to inside it through impact (the “over-the-top” move). This is usually the result of initiating the downswing with the upper body before the lower body has shifted and rotated, causing the club to come “over the top.”
- Combination of both — Most slicers have both an open face and an out-to-in path. The open face produces the curve; the out-to-in path makes it worse and also produces the weak, pulled start direction.
Step 1: Fix Your Grip
The grip is where most slice corrections should begin, because grip directly affects club face angle at impact. A “weak” grip (hands rotated too far toward the target, showing only one or two knuckles on the lead hand) makes it nearly impossible to close the club face through impact. The fix is to strengthen the grip.
How to Strengthen Your Grip
- Hold the club in front of you horizontally.
- Place the lead hand (left hand for right-handers) so you can see 2–3 knuckles when you look down at your grip. The “V” formed by your thumb and forefinger should point toward your trail shoulder.
- Place the trail hand so the “V” also points toward your trail shoulder. The palm of the trail hand should face toward the target rather than toward the sky.
- Take your address position. The face should feel slightly closed compared to what you’re used to — this is correct.
A stronger grip allows the forearms to rotate naturally through impact, closing the face without conscious effort. Many golfers fix 50–70% of their slice with this single adjustment. Combine this with other improvements to your course management and you’ll be shooting lower scores in no time.
Step 2: Fix Your Setup and Alignment
Most chronic slicers set up aiming left to compensate for the curve. This compensatory alignment actually makes the slice worse — it encourages an out-to-in swing path to send the ball toward the now-left target, which opens the face further and makes the curve more pronounced. It becomes a self-reinforcing loop.
The Alignment Drill
Place two alignment sticks (or clubs) on the ground at the driving range: one pointing at the target on the ball-target line, and one parallel to it at your feet line. Your feet, knees, hips, and shoulders should all be parallel to the target line — railroad track alignment. Verify your club face is also aimed at the target. Most golfers are shocked to discover how far left their body has been aimed when they do this drill for the first time.
Step 3: Fix Your Swing Path
Even with a strengthened grip and corrected alignment, many golfers still have an out-to-in path that they need to address. The over-the-top move comes from initiating the downswing with the upper body rather than the lower body.
The Downswing Sequence Drill
At the top of your backswing, before you start down, consciously shift your weight to your lead foot first. Feel your hips bump slightly toward the target, then rotate. The arms and club should “drop” into the slot behind your body before coming through impact — a feel many golfers describe as “swinging from the inside.” An image that helps many golfers: imagine there’s a wall directly in front of the ball (toward the target). Your job is to swing the club head inside that wall on the downswing before bringing it to the ball. This prevents the over-the-top move.
The Headcover Drill
Place a headcover just outside the ball, 6 inches from it toward the target line. Practice swinging without hitting the headcover. To avoid the headcover, you must swing from the inside. This physical constraint trains the correct path faster than any amount of verbal instruction.
The Gate Drill
Place two tees in the ground: one 4 inches behind the ball on the inside (closer to your feet) and one 4 inches ahead of the ball on the outside (further from your feet). Swing the club through the gate without touching either tee. This narrow channel forces an inside-out swing path — the opposite of the slice path.
Step 4: Fix Your Impact Position
The wrists play a crucial role in face angle at impact. Most slicers “flip” the wrists through impact — the trail hand overtakes the lead hand, flipping the face open. The correct impact position has the lead wrist flat (or slightly bowed) and the shaft leaning forward toward the target slightly. This maintains the face square through contact.
Wrist Drill
Hit short shots (half swings with a 7-iron) focusing on reaching impact with the back of your lead hand facing the target. If your watch face were on the back of your lead hand, it should face toward the target at impact. Practice 10–15 short shots with this sole focus before increasing swing length. This directly trains the non-flip wrist action that keeps the face square.
Quick In-Round Fixes When the Slice Returns
On the course, you don’t have time for extensive drills. When the slice returns, use these quick adjustments:
- Strengthen your grip one click — rotate the lead hand slightly further under the grip so you see one more knuckle
- Check alignment — aim your feet parallel to the target line, not left of it
- Think “low and slow” on the takeaway — a rushed, steep takeaway is a common trigger for the over-the-top move on the downswing
- Feel the lag — consciously feel the club head “lagging” behind your hands on the downswing rather than casting it outward

Common Mistakes When Trying to Fix a Slice
- Aiming further left — this is compensation, not a fix; it makes the underlying problem worse
- Swinging harder — more speed with a faulty path amplifies the slice; slow down and fix the mechanics first
- Only working on one cause — if you have both an open face and an out-to-in path, fixing only the path often turns the slice into a straight pull; you need to address both
- Making too many changes at once — change one thing per session; multiple simultaneous changes create confusion about what’s working
- Not using video — filming your swing from face-on and down-the-line with a smartphone is the fastest way to confirm whether your path and face changes are actually happening; feel is notoriously unreliable, especially for new movements
How Long Does It Take to Fix a Slice?
With consistent practice of the drills above, most golfers see significant improvement within 3–6 practice sessions. A grip change typically produces immediate results on the range. Swing path changes take longer to consolidate — expect 4–8 weeks of regular practice before the new movement feels natural under pressure. The pattern will often revert temporarily under competitive conditions (this is normal — new motor patterns are fragile under stress) before eventually replacing the old one.
Working with a PGA professional for even one or two lessons during this process accelerates the timeline considerably. A good teacher can identify which of the three causes is primary for your specific swing and direct your practice more efficiently than self-directed work allows. Make sure your body is supporting the swing mechanics too — our golf injury prevention guide and pre-round warm-up routine keep your body ready to make the changes that matter.
