When you play 18 holes, you know you’re going to putt the ball into the hole 18 times. The structure of par assumes you need 36 strokes to get the ball on the green in 18 holes. That’s 54 strokes, guaranteed, every time you play.
The questions you need to answer are, what are you doing with the shots from #55 up to your average score? And which of them you can get rid of most easily?
Extra putts? Of course there are going to be some. But if there are more than 18 extra, that’s too many. An extra 14 would be nice.
Extra swings? Make good contact and hit the ball straight. This isn’t difficult if you get lessons to learn what you’re supposed to be doing. Hint: it might take more than one lesson.
Penalty strokes? Keep the ball in bounds and out of water hazards. See above.
Extra recovery shots? Hitting out of tall grass, hitting out of trees, all that’s going to happen, so learn to get out of trouble and back in play in ONE shot. Don’t get greedy.
Extra chips? One per hole. First chip gets on the green. Close to the hole is better.
Extra pitches? One per hole. The green is a HUGE target. But if you aren’t good enough yet to hit it on the fly every time, hit a pitch and run with an 8-iron. Even if you can hit it on the fly, if the pin is sitting right in front of you and there is good ground between it and you, go with the 8-iron.
Extra sand shots? The pros say this is the easiest shot in golf. It is, but it’s a lot like learning to ride a bicycle. Get a lesson and practice. Once you know how to do it, it’s the easiest shot in golf.
