Choke down on the club slightly, keep the ball back in your stance, place 60% of your weight forward and finish low
Build your swing from the ground up by hitting balls off a tee with short strokes and elongating the swing as you gain proficiency
A great visual drill to fix an outside in swing path is to place a string on the ground to represent the target line and place a head cover just outside of the line, this will visually help you keep the club inside on the downswing so that you do not hit the head cover
