5 Drills to Fix a Slice: A Pass/Fail Range Plan

Key takeaways

• A driver slice comes from an open clubface, an out-to-in path, or both, and the face should be fixed before the path to avoid a bigger push-slice.
• A 10-ball test at the range, logging start line and curve, tells you whether your slice priority is face, path, or both.
• Each drill has a measurable pass/fail checkpoint, such as 8 of 10 balls starting at or left of the target line, so you know when to progress or drop back.
• One 45-minute range session a week, run for at least three weeks, is enough structure to change the pattern.
• Fairways missed right is the first stat to improve; strokes gained off the tee follows only once the ball finishes in play more often.

A slice comes from an open clubface, an out-to-in path, or both, and five progressive drills fix it: split-hands face control, a path gate, a headcover block, a closed-stance exaggeration, and start-line-only drives. Each drill has a measurable checkpoint and a progression rule, so you know when to move on, and the whole plan fits one 45-minute range session a week.

Why does a driver slice happen in the first place?

A driver slice has two root causes, and every drill you'll run targets one of them.

The two root causes: open face and out-to-in path

The ball curves right because the clubface is open to the club path at impact, usually combined with an out-to-in swing path moving left through the ball. Face direction controls roughly 75-85% of the starting direction on a driver, so an open face both starts the ball right and puts spin on it that curves it further right. Most slicers have both faults, but one usually dominates.

Why ball flight laws decide your drill order

Face-to-path relationship determines curvature, which is why the drills below fix the face first, then the path. Fixing path before face can make the slice worse: a more in-to-out swing with the same open face produces a bigger push-slice. Track your face and path separately if you can, the same way strokes gained tools isolate where shots leak hole by hole rather than dumping everything into one benchmark, as described in SQR1's cookie policy.

How do you diagnose your slice before picking a drill?

A slice is a face-and-path problem, but the mix differs for everyone. Read your ball flight first: the start line tells you where the face was pointing, and the curve tells you how the path compares to it.

The three slice shapes and what they tell you

Ball flight	Face at impact	Path	Priority
Starts left, curves right	Square or slightly closed	Well right of face	Path
Starts at target, curves right	Open	Also open, but less	Both
Starts right, curves further right	Very open	Roughly square	Face

A 10-ball test you can run at the range

Aim at a fixed target, hit 10 drivers, and log each start line and curve against the table above. Eight or more in one row means you have a single priority; a spread means both leaks need work. Track the same test weekly so you can see the shape change as your drills take hold, and log the results hole by hole in SQR1 GOLF (privacy policy) to see whether fairways hit improves alongside the range data.

Drill 1: The split-hands face control drill

How to set it up

Grip the driver normally, then drop your trail hand down so it holds the shaft split from the lead hand, roughly three inches apart. Make slow, three-quarter swings and pay attention to what the lead hand does through impact. Because the hands are separated, you can feel the clubface rotate from open to square to closed instead of guessing. Ball flight tells you the truth here: a face that is open relative to the path starts the ball right of the target line and curves further right, which is the standard face-and-path relationship used in launch-monitor teaching (TrackMan's ball flight fundamentals). If your starts are right and the curve is right, the face is your first leak. This is the drill to fix slice issues that come from a face stuck open at impact.

Pass checkpoint: split-hands start line

Hit ten balls with the split grip. You pass when eight start at or left of your start-line target, not when it feels good. Once you hit that, rejoin your hands, hit twenty normal-grip balls, and keep the same start-line standard. If you drop below eight out of ten, go back to the split grip. Log the result in your round or range notes, then benchmark it against your target handicap hole by hole (SQR1 GOLF terms).

Drill 2: The tee-in-the-ground path gate

Building the gate

Tee a ball up, then push a second tee into the ground about a foot behind it, angled so the line between the two tees points roughly 10-15 degrees right of your target (for a right-hander). Push a third tee into the ground about 8 inches outside and slightly behind the ball. Your job: swing the clubhead from the back tee through to the ball, missing the outside tee. That outside tee is your slice sitting there in physical form. Hit it and you came over the top again.

Pass checkpoint: the gate at half speed

Start with half-speed swings, no ball, just brushing the ground along the gate. You pass when you can hit 10 in a row without clipping the outside tee. Then add the ball at half speed: 10 balls, 8 or more starting right of target with a draw-ish curve. Only when that holds at half speed do you go full. Log your misses each session; if you are still clipping the tee after three sessions, the path problem is bigger than the drill, and your round data at SQR1 GOLF will usually show it as a fairway-miss pattern to the right.

Drill 3: The headcover outside the ball

Setup and common faults

Place an empty headcover (or an old glove) about 15cm outside the ball, slightly behind its position, angled along your target line. The goal is simple: your club must travel inside that obstacle on the downswing. An out-to-in path swings over it, so any slice-producing move gets punished immediately by a clipped headcover rather than a guess.

The common fault is cheating: moving the headcover further out until you can miss it comfortably. Keep it tight enough that a shallow, inside-out swing just clears it. A second fault is stalling your rotation to steer the club around the obstacle, which produces a block. If you start hitting pushes, that is progress, not a new problem.

Pass checkpoint: clearing the headcover

Hit ten balls; nine must miss the headcover with a start line inside the target. Two clean sessions in a row means you progress to Drill 4. Still clipping it after three sessions? Your face control from Drill 2 is not holding under speed, so go back and slow down. If you want a second opinion on your setup, send us a note at SQR1's contact page.

Drill 4: The closed-stance exaggeration

Once the face feels stable, path is the next leak. A slice almost always comes with an out-to-in swing, so this drill overcorrects by pulling your alignment the other way.

How to set it up safely

Drop your right foot back so your feet, hips, and shoulders aim 20-30 yards right of the target while the clubface still points at it. Hit half-speed three-quarter swings, feeling the club travel from inside the ball toward the target line. The exaggerated stance makes an in-to-out path feel strange at first, then normal. Keep the ball position off the lead heel so you are not adding loft de-lofting problems on top of the path change.

Pass checkpoint: start right, curve back

Checkpoint: 8 of 10 balls start right of the target line and curve back toward it. That ball flight proves the path has moved in-to-out. Once you hit it, narrow the stance back toward square over three sessions, keeping the same start line. Because blocked repetition like this is how a new pattern gets grooved before you test it under variable conditions, stay on this drill until the checkpoint is met rather than rotating drills every five balls (Practice Caddie on coaching apps). If balls start hooking left, you have overcorrected: close the stance less, not the face.

Drill 5: The start-line-only driver drill

The corridor and the checkpoint

This is the drill that ties everything together. Pick a target 100 yards out, lay two alignment sticks on the ground forming a corridor about 10 yards wide at that distance, and hit drivers aiming to start the ball inside the sticks. No headcovers, no stances, no swing thoughts: your only job is to read the start line.

That matters because start line is the most honest measure of face control. Path bends the flight after it starts; the face decides where it leaves. If your ball starts left of the corridor, your face is still open relative to your path, whatever your swing feels like.

Pass checkpoint: the narrow corridor

Hit 10 balls. Pass: at least 7 start inside the corridor. Then tighten the corridor to 5 yards and repeat. When you can pass two consecutive sessions at the narrow width, take it to the course and pick a start-line target, not a landing spot, on every tee.

How should you structure a week of practice to fix a slice?

A 45-minute session plan

Split your single range session into three blocks. Spend 15 minutes on Drill 1 (split-hands) and Drill 2 (path gate), 20 minutes on whichever drill you have not yet passed, and 10 minutes on Drill 5 hitting full shots to a start line with your normal grip and stance. Run the same structure for at least three weeks before changing anything. Progressing a drill early is how swing thoughts pile up.

How to track whether the slice is actually shrinking

Count fairways hit in your weekly round, not feel. A 15-handicap typically hits a minority of fairways, and strokes gained benchmarks by handicap tier show driving is where mid-handicappers leak most versus their target (The DIY Golfer on strokes gained apps). If your fairway count rises over four rounds while your start line holds on the range, the drills are working.

Can tracking your rounds tell you when the slice is fixed?

The stats that move first

Fairways missed right is the earliest signal. If your tee shots leak right on holes where the trouble sits down the right side, that count should drop before your fairway percentage climbs, because start line corrects before dispersion tightens. Strokes gained off the tee follows last: it only improves once the ball finishes in play more often, not when contact feels better on the range.

Give it three to five measured rounds. One good round proves nothing; a trend does.

Where SQR1 GOLF fits, and where it falls short

SQR1 GOLF benchmarks your round hole by hole against your target handicap across 14 tiers from +4 to 54, so a 15-handicap compares against 15-handicap expectations rather than tour baselines, and flags where shots leak, hole by hole. It tells you what to fix, and the drills in this article are what you take to the range.

Where it falls short: it does not track clubface or path directly, so it infers a slice from outcomes like missed-right fairways and start line rather than measuring impact data the way Arccos Golf sensor systems do. If you want face-and-path numbers from every shot, pair it with a shot-tracking tool and use SQR1 for the handicap benchmark and the practice priority.

FAQ

How long does it take to fix a driver slice with drills?

Most golfers see a measurable start-line change within three to five range sessions if they hit the checkpoints. The full plan runs at least three weeks at one 45-minute session per week, plus three to five measured rounds to confirm fairways missed right is actually dropping. If a drill still fails its checkpoint after three sessions, drop back a drill rather than pushing on.

Should I fix my grip first if I slice the ball?

A weak grip often contributes to an open face, but the drills here attack the problem through ball flight, not grip overhauls. The split-hands drill teaches you to feel the face rotate to square, which works regardless of grip style. If eight of ten balls still start right after passing that drill, then adjust your grip to a stronger position and retest.

Can I fix a slice with an iron swing but still slice the driver?

Yes. The longer shaft, more upright lie, and ball position off the lead heel make the driver harder to square, so face control that holds at iron speed often breaks down with the driver. That is why every checkpoint here uses drivers specifically. If your irons draw but your driver starts right and curves further right, your face control is speed-dependent, not fixed.

Do slice-correction training aids work, or are drills enough?

Aids can help, but every drill here uses cheap physical feedback instead: a split grip, tees as a gate, a headcover as an obstacle, alignment sticks as a corridor. Each gives you a pass or fail signal without buying anything. If you already own an impact or path aid, use it inside these checkpoints, but the progression rules matter more than the equipment.

Why do I still slice even when I aim further left?

Aiming left does not close the face; it usually makes the out-to-in path worse, so the ball starts left and curves even further right. The face decides the start line, and the path relative to it decides the curve. Fix the face first with the split-hands drill, then correct the path with the gate drills, and stop compensating with alignment.
