Strokes gained putting

Strokes gained putting measures every putt against the tour average from its starting distance: expected putts from where the ball lies, minus expected putts from where it finishes (zero when it drops), minus one for the putt. Summed over a round it says how many strokes the putter won or lost against a tour field from the same distances.

strokes gained = expected strokes before - expected strokes after - 1

The expected putts table is the whole category. From 3 feet the tour average needs 1.053 putts, from 8 feet 1.515, from 18 feet 1.840, from 30 feet 1.984 and from 45 feet 2.097. Holing an 18 footer is worth +0.840. Lagging it to 2 feet is worth -0.169: slightly negative, because from 18 feet the average player leaves a little less than a two-putt.

Putts per round can move in the opposite direction to putting skill, because it depends on where the approaches finished. A golfer who misses greens chips close and takes 30 putts from short range; a golfer who hits greens to 40 feet takes 31 from long range and putted better. Strokes gained prices each putt from its own distance, so a two-putt from 45 feet (+0.10) and a two-putt from 8 feet (-0.49) are finally different numbers.

A three-putt from 45 feet, lagging to 4 and missing to 2 before holing, costs -0.90 in total, and it is the one ordinary putting mistake that costs a full stroke on its own. Putting carries about a seventh of an amateur’s gap to a tour field on Broadie’s split, spread over roughly 30 putts a round, which is why it is the most practised category and the slowest to move a handicap.

Four putts, priced

Every putt against the tour average from its own distance.

The lag from 45 feet to 4 is a gain and the miss from 8 feet to 2 is a loss, which is the opposite of how a putts per round column reads them.

Expected putts by distance

The tour average number of putts from each distance, and what holing the putt is worth.

Putting in PinFlag

On the green you place the leave in feet for every putt, so each one is priced from its own distance against the expected putts table, and the holed putt closes the hole. The scorecard derives putts per hole from those putts rather than asking you to count them.

Insights shows strokes gained putting per round and across the season, three-putt frequency, make rate by distance from your recorded makes, a heat map of where your leaves finish around the hole, and three-putts under Score Killers, so a long-range lag problem and a short-range miss problem show up as different numbers.

Frequently asked questions

How is strokes gained putting calculated?
Expected putts from the starting distance, minus expected putts from where the ball finishes (zero if it drops), minus one. From 18 feet the tour average is 1.840 putts, so holing it is worth +0.84 and two-putting it is worth -0.16.
What is a good strokes gained putting number?
Zero is the tour average. A 15 handicap gives up roughly 2.4 strokes a round on the greens on Broadie’s split, which is the smallest of the three categories. Against your own history, fewer three-putts moves the number fastest, because a three-putt is the one putting mistake that costs a full stroke.
Why is putts per round a misleading stat?
Because it depends on where the approaches finished. Missing greens and chipping close produces fewer putts from shorter range; hitting greens to 40 feet produces more putts from longer range and better putting. Strokes gained prices each putt from its own distance, so the two are separated.
What does a three-putt cost in strokes gained?
From 45 feet, lagging to 4 feet, missing to 2 and holing costs -0.90 in total. It is the one ordinary putting mistake that costs a full stroke on its own, which is why PinFlag counts three-putts under Score Killers.
How does PinFlag measure make rate?
From your recorded makes by distance: the share of putts you holed from each range, shown alongside the tour expected putts figure, with the count behind every rate so a small sample is visible as a small sample.
