The term getting it up and down is a golfing expression that refers to the act of hitting the ball onto the green and then into the hole in as few strokes as possible. It's a challenge for even the most experienced golfers because, as anyone who has played the game knows, there are a lot of variables that can come into play when trying to hit a small target from long range. Even the slightest mis-hit can result in an errant shot that ends up well off-target.
That's why getting it up and down is considered one of the toughest shots in golf. But when you pull it off, it's an extremely satisfying feeling. And if you can do it on a regular basis, you'll be well on your way to posting some low scores.
