I usually try to hit these without taking too much sand first, i.e like a regular pitch or lob shot.

Use a low bounce wedge with as much loft as you need to get over the lip, place ball in middle of stance, do not open club face. Make a smooth swing, sweep the ball with as little sand as possible (½ inch max) and finish in a full follow-through.

The ball will fly and roll more but the high lip should not be a problem. Always practice these shots before using them on the course.

Good luck!
