Green Side Bunker Shots

Similar to shots from the turf, greenside bunker shot techniques have changed over time with the advancement of wedges, sand, green surfaces, etc....Players should focus on staying more square to their target line with the body and the path of the swing.  Using the bounce of the wedge and the ball towards the front of the stance, I would like to see players swing towards the sand underneath the ball instead of focusing on sand behind the ball.  Adjusting the depth and length of the swing for the distance of the shot.
