The Causes of Duck Hook and How to Fix it

The direct cause of duck hook is a closed clubface at impact. There are two types of cause.

1. Clubface is closed at impactc + Swing path is inside in

2. Clubface is extremely closed + Swing path is either inside out or inside in

 

Golfers hitting duck hooks tend to hit a hook or draw on regular shots. If your normal shots is right to left shot, you have to aim right of the target to work the ball to the target. But if you align your body square to the target, you are going to hit a hook or duck hook to the left. Golfers with this type of problems usually swing inside out to compensate for the closed clubface at impact.

 

But for some reason, if they swing inside in, they are going to hit a duck hook. So duck hooks usually happen when hookers try to hit it straight.

 

How to fix it

So fix your your duck hooks, you need to understand that your clubface is closed at impact if you swing inside in. If you swing inside out, you will probably hit it straight (at least it looks like a straight shot) or little draw. But this is not going to cure the root of the problem.

 

The real problem is somewhere else. First thing to do is to look at your grip. Rotate your left hand to the left until you'll see 2 1/2 knuckles of your left hand. Pay attention to your right hand. Make sure the V formed by your right thumb and index finger points more toward your right ear.

 

The Drill for Duck Hook

Here is the drill used by Jim Mclean to fix pros' duck hooks. Let's use 6 iron for this drill.

1. Position your ball in line with your left heel.

2. Flare your right toe about 45 degrees.

 

Now try to hit a fade from this position. Hold your wrist through impact and try not to turn your face over. This drill is for advanced players, but Jim Mclean said it work really well.

 

The Ball Position

When hookers position the ball too much left, they can easily hit a duck hook because they tend to close their face at impact. So if you normally hit a draw, move the ball a bit to the right to avoid duck hooks. But if you position it too much right, you are going to block the shot to the right so you need to experiment with ball positions. With a driver, you might want to try placing the ball one or two ball length right of your left heel if you draw the ball.
