Be good at the basics of setup and swing keys for greenside bunker shots and get out and on the green more consistently.
Having the proper setup and technique for greenside bunker shots is the key to getting out and on the green more consistently. Flat, uphill, and downhill lies are discussed in this video filmed during a group coaching program at St. Davids Golf Club.
A few things to keep in mind when setting up to play these shots from the sand are listed below.
Weight left (60%)
Slightly open stance at address
Work your feet into the sand for a stable base
Square club face for wet, firm sand; open club face for dry, soft sand
Shoulders match the tilt of the slope
So to recap, if you want to hit better bunker shots you need to setup properly, keep your head still and weight forward during the backswing, and make a long enough follow through. Do these things and you will have more success getting out of bunkers.
