Here we have a 'buried ball,' the ball has landed in the bunker and dug in and nearly all of the ball is submerged. Principle in the bunker, you must get your sand club to go lower than the bottom of the ball when you're playing a green side shot.
How to Produce a Divot
Now if the ball is sitting clean, it only has to go maybe an inch. But here it's got to get down a good two, two and a half, three inches, to get this ball out. So I want to use a different part of the club than when I'm playing a good lie where I use the flange and let it skid and bounce through and it produces a divot.
On this shot I need the divot to be much deeper. I'm going to put my hands forward and square the club so that the leading edge can act as a digger and dig well beneath the ball. I'm not trying to lift it; I'm letting the force of the sand blow the ball out. Now I'm going to position the ball at about the middle of my feet and I'm going to stand on the outside edge of my front foot and the inside edge of my back foot.
How to Follow Through on a Bunker Shot
With my hands forward I'm going to swing until I can't swing down any more, I may not have a big follow-through but I'm not quitting, the sand is just stopping my club. Allow for some roll because the ball is going to come out a little more tumbling but if you can get a sharp impact, you can pop the ball up and let the height help slow the ball from rolling across the green. Remember 'buried lie' you must get lower than the ball, you use the digging edge of the club and you assume a position that will create more descent.
