To grip the golf club with the palm of the left hand instead of the fingers is a common mistake of golfers. This is a mistake, as it prevents the left hand from gripping in its natural position, turned slightly inwards. The clubface will open as the arm stretches out during the downswing, slicing the ball as a result of this. You would then have to compensate by stopping your body earlier in the downswing, turning your hands earlier to ensure the clubface meets the ball square on to avoid slicing. The real solution is to grip with your left hand in the correct position.

So avoid the common mistake of a faulty grip during set up. This will help you prevent ruining your golf game at the outset.
