Hook
In short
A hook is a golf shot in which the ball flies in a strong curve from right to left (for right-handers; mirrored for left-handers). It happens when the clubface is closed to the swing path at impact. A slight hook is called a draw and is often played on purpose. A hook that is too strong costs distance and control.
What is a hook in golf?
In a hook the flight of the ball curves strongly sideways. For right-handers the ball moves left, for left-handers right. Where this text says ‘left’, it refers to right-handers. The name describes the hook-shaped flight: the ball starts straight or right of the target and then bends sharply to the left.
A hook is a flight fault, much like its opposite, the slice. It is unpleasant for many players because the ball lands far left of the fairway, often in the rough, in water or out of bounds. The particularly severe version is the ‘duck hook’: the ball flies low and turns abruptly left, then runs a long way. A hook has a spin axis tilted strongly to the left, often loosely called side spin, and usually comes from a combination of clubface position and swing path.
How a hook happens: clubface and swing path
Two things decide the ball flight: the direction of the clubface at impact (face angle) and the direction in which the clubhead travels (club path). The ball starts mainly in the direction the clubface points. How much it curves depends on the difference between the two values. That difference is called ‘face to path’.
In a hook the clubface is closed relative to the swing path, so it points further left than the path. TrackMan shows this as a negative face-to-path value. An example: the clubface points exactly at the target (0 degrees), but the swing path runs in-to-out at plus 6 degrees. Face to path is minus 6 degrees. The ball then starts almost straight, if anything slightly right, and bends left. Even small values have an effect: according to TrackMan, for tour players with the driver, about minus 2 degrees already produces around 17 metres of curve to the left.
Hook, draw, pull and pull hook: telling them apart
Several terms are often confused:
- Draw: a slight, controlled curve to the left. The ball starts right of the target and returns towards it. Many good players play it on purpose because it adds roll.
- Hook: a strong curve to the left. The ball starts straight or right and ends far left.
- Pull: the ball starts left of the target and then flies straight. Both the clubface and the swing path point left, and face to path is about zero.
- Pull hook: the ball starts left of the target and also curves further left. The result is a ball that ends up very far left.
- Slice: the opposite, a strong curve to the right.
So the difference between draw and hook is mostly the amount of curve. A draw is a controlled hook within the width of the fairway. If you hook unintentionally, you have too much curve.
Causes: why do golfers hook?
The most common reasons for a hook are:
- A grip that is too strong: your hands are turned too far to the right on the club. With the left hand you can see three to four knuckles. That tends to close the clubface in the swing.
- Active hands: the wrists and forearms roll over too early before impact, closing the clubface too much.
- A path that is too far in-to-out: the club approaches the ball too much from the inside and swings out to the right. That gives a positive club path.
- Ball too far back in the stance: the club reaches the ball while it is still travelling more from in to out. That increases the path to the right and can encourage a push or a hook.
- Aiming right: if you aim too far right, you unconsciously correct with your hands and close the clubface.
- Lie of the ball: with the ball above your feet it tends to hook (see uneven lies).
One cause alone is often enough. Usually several combine, which is why it is worth looking at the data.
Practical example: a hook on a par 4
A par-4 hole is 360 metres long, with a pond to the left of the fairway marked as a red penalty area. You aim the driver at the middle. The ball starts straight, curves sharply left and lands in the pond. That is the hook.
Since the ball is in a penalty area, you have relief for one penalty stroke. With red stakes, lateral relief is available as an extra option (Rule 17). You then drop a ball within two club-lengths of the point where the ball last crossed the edge, no nearer the hole. Your first stroke was the tee shot, the second the penalty stroke, and the third comes from the drop.
At best your third stroke, from the drop, reaches the green. With two putts the card then shows a 5, a bogey. If the third stroke finishes beside the green, a double bogey follows quickly. A hook into the penalty area therefore costs at least one penalty stroke, which is why many players want to get rid of the hook above all.
Fixing a hook: tips for a controlled ball flight
Fixing a hook is mostly about grip, alignment and hands. Work through it in this order:
- Check your grip: turn both hands slightly left into a neutral position. With the left hand you should then see about two knuckles.
- Check your alignment: lay two alignment sticks on the ground, one for your feet and one for the ball-to-target line.
- Check ball position: play the ball a little further forward, with irons about the middle of the stance.
- Less hands: swing with your body, not your hands. Let your hips turn to the target and hold the clubface to the target for longer.
- A high finish: a high finish shows that your hands did not roll over too early.
Important: do not change everything at once. Change one thing per practice session. Then you can see what works.
Measuring a hook: what TrackMan shows you
The measurements show the cause of a hook most clearly. TrackMan measures these values, among others:
- Face angle: where does the clubface point at impact? A value left of the target means the ball starts left.
- Club path: in which direction does the clubhead travel? For right-handers positive values stand for an in-to-out path.
- Face to path: the difference between the two values. A negative value means a curve to the left.
- Spin axis: the tilt of the spin axis. For right-handers a negative value means a curve to the left.
So you can quickly see whether the clubface is too closed or the path comes too much from the inside. The advantage: you work on one value at a time instead of everything at once.
Try it at Golf Lounge
The measurement gives important clues as to whether your hook comes mainly from the clubface or the swing path. At Golf Lounge Resort Hamburg, TrackMan III provides radar ball-flight measurement at every tee bay and in the simulator boxes. It measures launch angle, ball speed, clubhead speed, carry distance and spin, among other things. V1 Pro video analysis is available as a supplement. The boxes can be used all year round whatever the weather, with up to four people playing per booking.
Frequently asked questions
What is a hook in golf?
A hook is a shot in which the ball curves strongly to the left (for right-handers; mirrored for left-handers). It happens when the clubface is closed relative to the swing path at impact. The ball starts straight or right of the target and then bends sharply. A slight hook is called a draw.
What is the difference between a hook and a draw?
Both curve to the left. A draw is a slight, controlled curve that many players use on purpose to gain roll. A hook is a strong curve that takes the ball far from the target. The difference is therefore mainly the amount of curve.
What are the most common causes of a hook?
Typical causes are a grip that is too strong, hands rolling over too early before impact, a swing path that is too far in-to-out, a ball too far back and aiming to the right. Usually several causes combine. A ball above your feet on a slope also tends to hook.
How do you fix a hook?
Start with the grip: turn both hands into a neutral position, with about two knuckles of the left hand visible. Then check alignment and ball position. Swing with your body instead of your hands and hold the clubface to the target for longer. Change only one thing per session.
What is a duck hook?
A duck hook is a particularly severe hook. The ball flies low, turns abruptly left and then runs a long way. It usually happens when the clubface is very closed to the swing path. For many players it is the most unpleasant mishit because the ball ends up far left.
