When you play bunker shots, the reason that most people miss bunker shots is the bottom of their swing is too far behind the ball. That ball I just hit was played right off of my heel and I hit three to four inches behind it. The bottom of my arc was almost right underneath the golf ball. We see most people where the bottom of the arc being way back where they hit the shot fat or bounce the club into the ball. Now what can you do about this? In a practice bunker you can draw a line. Put that line about two inches behind your left heel and just simply find out where the bottom of your arc starts. Position the golf club as if the line were the ball and you were trying to hit the ball first off of the grass. When I just swung did you see where the bottom of the arc started, at the line and then it went forward. Now if I can do that I am well on my way to hitting good bunker shots. If I put the ball behind the line I am going to hit the ball first. So what am I going to do, I am going to put the ball forward of the line up well into my heel and make the same exact swing that I just practiced. In doing that notice how my divot started forward, still went beneath the ball, and I got a great bunker shot. Never stay back on your back foot and try to lift up and scoop. When this happens you are in real trouble in the bunker. Swing the club, turn back through, learn to control where the bottom of your arc would be. Get the ball two or three inches into that divot so that you are taking the sand two to three inches behind the ball and not a foot behind as so many people do.
