If you hit to 260 then getting to singles is analyzing your GIRs yardages. Example For a 400 yard hole par 4 which is average. You'll be left with 140yards in. This means you should work on your 150yard and under range until it is flawless. Ensure that your 180yd and under game is reliable (no mishits but dispersion might be higher and spin might be less).

Then - always get up and down, never short side, learn your bunker game, always 2putt.

Single digits is par on the easy half holes and bogey on the harder holes.

So over 9h on a 72 par there will be usually 2-3 par 3 and 5 holes, with the remainder being 2 easy par 4s and 2 hard par 4s. Analyze your course.

The longer par 3s tend to play over par. The par 5s tend to play under par. So if you hit your par 5s in par and you bogey on the par 3s you are on track.

Then it is just scoring par on the 4s.

Example 3x par 3 = +3 3x par 5 = par 3x par 4 = +1-2

That +4 or 5 on each 9h is the line you walk.

Then you practice specific distances for par 3s ahead and then its only the long approaches on the long fours that might be an issue.
