A sand save is a shot played from a bunker that results in the ball remaining on the green. The term is most commonly used in golf, but can be applied to any sport where the objective is to keep the ball on the playing surface.
There are two main types of sand saves: up and down, and lip out. An up and down is when the ball is hit from the bunker onto the green and then rolls into the hole. A lip out is when the ball hits the edge of the hole but does not go in.
The main difference between an up and down and a lip out is that an up and down requires less precision since all you need to do is get the ball onto the green. A lip out, on the other hand, requires more precise aim as you need to hit it right on the edge of the hole.
In general, an up and down is considered to be more difficult than a lip out because it requires more control over both distance and direction. However, there are some players who prefer up and downs because they find them more challenging and rewarding.
