Stay loose on greenside sand shots
Don’t shorten up and brace for impact in the bunker. You want your swing to feel long and unhurried. Your left wrist should cup at the top as if it’s bending from the weight of the clubhead. Make practice swings with your left hand only and, when you reach the top, check that wrist and make sure it’s more cupped (above). This will help open the clubface. From here, keep the hands relaxed when you swing down, and let the club glide through the sand.
