The short version
Strokes gained measures how every shot you hit compares to a benchmark golfer from the same position. Hit a drive 280 yards to the fairway? That might gain you +0.3 strokes vs. a scratch golfer who averages 260 to the fairway from the same tee. Three-putt from 15 feet? That probably costs you -0.7 strokes.
Add it all up across a round and you know *exactly* where your game is strong and where it bleeds.
Why traditional stats lie
Fairways hit and greens in regulation sound useful. They're not. A player who misses every fairway by 5 yards into light rough is fundamentally different from one who misses by 40 yards into the trees. Traditional stats treat both the same.
Strokes gained captures *how much* each shot costs or saves you. It's the difference between counting and measuring.
The four categories
Strokes Gained: Off the Tee — Your tee shots on par 4s and par 5s. Not just "did you hit the fairway?" but "how far, and from what position?"
Strokes Gained: Approach — Iron shots into greens from 100+ yards. This is where most amateur golfers lose the most strokes.
Strokes Gained: Around the Green — Chips, pitches, bunker shots within 50 yards. The scoring zone.
Strokes Gained: Putting — Everything on the green. Distance control matters more than you think.
What most amateurs get wrong
The average 15-handicap thinks they need a better driver. The data says they need better approach shots. Mark Broadie's research found that approach shots account for roughly 40% of the scoring difference between a scratch golfer and a 15-handicap.
That doesn't mean your driver doesn't matter — it means your irons probably matter more.
How to use this
It's not complicated. The hard part is being honest about the numbers.
