How to break 90

A bogey on every hole of a par 72 is 90. So breaking 90 is bogey golf minus 1 shot. Not a better swing, not more distance, not a putting stroke: one hole better than a bogey, eighteen times in a row without a disaster. That is the whole problem, and it is a different problem from the one most golf writing solves.

What the card looks like

89 is 17 over par. There are only a few honest ways to get there without birdies, and seeing them written out is usually the moment it stops feeling impossible:

Every row adds to 89. Birdies are excluded on purpose: nobody breaks 90 by making them.

Every row totals 89.

The trade that decides it. With no doubles you need 1 par and 17 bogeys. Make 3 doubles and you now need 4 pars. Every double bogey costs three pars, and pars are the hardest thing on this page to produce. That is why avoiding disasters beats chasing good holes.

What a double actually costs

Doubles are not bad luck, they are a small number of specific decisions. Each of these is priced from the published expected strokes tables rather than asserted:

Costs computed from the published expected strokes baselines. Every one of these is a full stroke or more.
What happenedStrokes lostHow that is worked out
A tee shot out of bounds on a 400 yard hole2.05You are on the tee again lying 3, so the hole now costs 5.99. A drive to the fairway leaving 150 costs one shot and leaves 2.95, 3.95 in all.
Three putting from 20 feet1.12Twenty feet averages 1.88 putts, so the third one is 1.12 you did not have to spend.
Three putting from 30 feet1.02Thirty feet averages 1.98 putts. A long first putt is meant to be two, which is why this costs less than the twenty footer.

Just two kinds of mistake cost a full stroke on their own, and neither is a bad swing. The most expensive is a tee shot out of bounds at 2.05 strokes. Two of those is the difference between 89 and 93. Note what is missing from the list: laying up from the rough is not on it, because the tables say advancing wins, which is the opposite of what golfers are usually told.

Where the strokes actually go

A 15 handicap gives up about 16 strokes a round to a tour field. Split by where they are lost, against how many shots each category gets:

Off the tee and approach

10.4

strokes a round, over 14 shots

Short game

3.2

strokes a round, over 7 shots

Putting

2.4

strokes a round, over 30 shots

10.4 of the 16 are lost before the ball is near the green, across just 14 shots. Putting costs 2.4 spread over 30 strokes, which is 0.080 a putt. That is why a month of putting practice barely moves a score and why the range does. The full benchmark tables break every handicap down the same way.

What to do on Saturday

  1. Take the tee shot that cannot go out of bounds, even if it leaves 40 more yards. At 2.05 strokes, no drive is worth that risk on a hole you are trying to bogey.
  2. After a bad shot, play to the middle of the green. The recovery attempt is the second shot that turns a bogey into a double.
  3. Aim at the centre of every green, not the flag. You are trying to two putt, not to make birdies you do not need.
  4. Take the bogey. Seventeen of them and one par is 89.

What is deliberately not on this page. The published expected strokes tables begin at 20 yards and are flat below it, so chipping and pitching cannot be priced from them. Every number here is a full shot or a putt. Other pages will tell you exactly what a chip is worth; that number has to be invented, and this one is not going to invent it.

Frequently asked questions

What handicap do you need to break 90?
Around 17 or 18 on a par 72. That is a golfer who averages a bogey a hole, which is exactly the point: bogey golf is 90, so breaking it needs one hole better than bogey, not a transformed swing.
How long does it take to break 90?
It depends far more on removing double bogeys than on adding distance or holing more putts. A golfer already shooting in the mid 90s is usually three or four blow up holes away, not a season of lessons away.
Do you need to make pars to break 90?
One. Seventeen bogeys and a single par is 89. If you make three double bogeys you need four pars to pay for them, which is the trade that decides most rounds in the 90s.
What is the fastest way to break 90?
Stop losing whole strokes to penalties and three putts. Just two mistakes in golf cost a full stroke on their own: a tee shot out of bounds is worth more than two, and a three putt from 20 feet is worth 1.12. Neither needs a swing change to avoid.
Should I focus on putting to break 90?
Not first. A 15 handicap gives up around 10.4 strokes a round in the long game and 2.4 on the greens, across 14 long shots and 30 putts. Putting is the smallest leak spread over the most strokes, which is why practising it moves a score so slowly.
