A great anti-slice drill that you can use is by drawing the right foot back at the point of address, and closing the body to your target line. When you draw the right foot back and you close your body to the target line, what it achieves is a totally different path through the point of impact. Normally when you’re slicing and if you’re setting a square or even aiming a little bit off to the left hand side, your club path will be traveling left as you hit. So travelling from out to in and moving off to the left hand side. If you can get yourself set up and pull the right foot a long way back from the ball, and then feel like your shoulders are also closing to match your knee position, what this will cause is a club path which moves very, very much from the inside.
A great way to do this drill is to use an exaggeration and then slowly bring it back so the right foot is only slightly back from the left hand side. So you could hit a few shots in a row with a real exaggerated position like this, notice how the club is moving a long way in the inside, and because of that on the way through I’m able to move it a long, long way from in to out. The whole point of this drill is to change path. Now I could do that but I just hit a shot straight off to the right hand side, so that’s where I can move in and actually get my hands working, get my release working as I move through the ball, or even combine this with the first drill and get that left wrist tucked under to cause a big draw. It is extreme amounts to do this drill all the way on the inside with that club face, you can start to hit some very, very big and some very, very exaggerated drills. So use that drill and then gradually just move that right foot back up to still get the feeling that you’re moving the club from the inside, and you should be able to find the point where you could hit a comfortable drill.
