This is not too bad of a shot to get out in 1. Here's how:

* Adjust the ball position in the back.
* Keep level shoulders to the horizon, not the hill. This is slightly different to normal shots where you want the shoulders to always be level with the ground's slope
* Do not open the SW up, but rather, keep it square or even shut slightly. Using a PW is not a bad option if you do not have a large lip to carry.
* Now, the strike:
---Hard---Powerful---and Downward---1 inch behind the ball
This gets the ball to pop up and out. Thinking that the club actually will make contact with the ball causing it to lift the ball out is what causes all the problems. Doing this strike into the hill and downward will create a crater of sand that is launched out and anything inside that crater will go with it...so if there is a ball in there, that too will go.
* There is no spin of course, so expect run but at least you are out.
