Downhill bunker lie
The key to breaking 90 is being able to save strokes from more difficult places, like a downhill lie in a bunker. Use your most lofted wedge, and open the face before taking your grip. Set up with your weight on your front side, then keep your lower body still with very little turn throughout the shot. This helps you maintain your balance.Your arms should dominate the swing. An early wrist hinge sets up a vertical backswing, allowing you to strike down and through the sand. It takes courage to make a firm, accelerating blow about four inches behind the ball. Make sure the clubhead doesn't pass your hands until the ball is well on its way, and allow for extra roll. You need to practice this shot to pull it off under pressure.
