One of the keys to getting out of greenside bunkers is to keep the clubface "open." When you close the face, you get a lower trajectory and the Golf Club tends to dig in the sand. Here's a trick to help you achieve this: Imagine that the clubface is a mirror, and that you're going to see your reflection in it at the finish of your sand shot. This will ensure that you take the club all the way to eye level and that you've kept it open all the way to the finish.
