A couple of years ago I was consistently great out of fairway bunkers. Last year and this one I have simply lost it. What I did 2 years ago was to set up in the impact position, choking down a bit on the club, and the ball slightly rearward of normal. Then try to swing without much lower body motion. These same things are not working now. I hit fat or very thin, and if I do catch one decently, it is a push-fade.
This year in my regular swing I've learned to delay my release somewhat, i.e. more lag. I used to throw away the lag very early. Perhaps that made fairway bunker shots easier. I suppose so.
What do you do in your setup, and in your swing?
more than anything in bunkers is to create a firm
mental image of how fast to whip the club through the sand.
Usually it's faster than appears necessary. If you're
worried about your technique you tend to be tense and
stop your hands early.
