I supposed if someone asked me the most common problem I deal with as an instructor, it would have to be the Slice. For right handed players this would be the ball that curves to the right and for most the ball curves too much. After years of different methods, about 10 years ago I realized the best way to fix the problem is to help the player to understand the problem. So how does a golfer hit a slice?
The first thing you need to know is that the ball starts where the face of the club is pointed at impact. If it is pointed right it starts right or left it starts left. So the first question to ask becomes, “Does the ball start right or left of your intended line? “
The curve is caused by spin. Spin is created when the direction the club is moving doesn’t match the direction the clubface is pointed. For example, if the path direction matches the direction the face is pointed, the ball goes straight on that path. If the path does not match the direction the face is pointed the ball spins and curves. The ball curves in the same direction the face is pointed relative to the path. If the face is pointed right of the path for a right handed golfer the ball curves right, and if it curves enough we call it a slice.
The solution comes from understanding the relationship of the face to the path. For right handed golfer the face is always pointed right of whatever path the club is on. Armed with this knowledge we can ask the question that fixes the problem. Why is the face pointed right of the direction the club is swinging?
The problem is in how a golf club is built. Because the shaft attaches in the heel or inside edge of the club, the club rotates around that point as it moves. In order for the face of the club to stay perpendicular to the direction the club is moving, the toe of the club has to rotate faster than the heel of the club. Slicers do not allow the toe of the club to move faster than the heel! The toe lags behind the heel as the club comes forward. I don’t think there is a best way solution other than to hold a club in front of you and get the feel of moving the toe of the club around the heel of the club. I think you will see this motion is created easily by rotating your forearms, hands and wrists. You will also feel and see it is easier to rotate the toe of the club faster coming forward if the toe rotates faster going back. If you can develop the feel of controling the toe of the club, longer and straighter shots are in your future.
