Slicing the ball normally means that the upper body sort of gets involved in the shot far too early. So once you’ve made a back swing this coming over the top action. The upper body unwinds far too early and it starts bringing the club with it.
So you get to the top of your backswing and the upper body unwinds and you can see how it wants to come over the top. Again it’s going to give you this kind of slicing action.
What I would like you to try and do is leave your back facing the target fractionally so as you start the down swing your back is still facing the target.
If I was going to make a back swing now. My back is facing the target now as I start down I’m just going to leave my back facing the target. What I don’t want to do is get the back working round too early because that will bring the club over and across.
So if you can get the back facing the target and keep it there. The arms will drop. The right elbow will drop in a little bit closer maybe to the right pocket and now the clubhead is approaching from behind my hands and then it can swing through and hit the shot from the inside.
So practice this at home or even down the range. Just make a back swing. Leave your back to the target and let your arms drop down so that right elbow just slots in and then hit from the inside.
