Score is a blunt instrument. You can shoot 78 with terrible ball-striking and great putting, or 78 with the opposite. You learn nothing from the number alone. Strokes Gained fixes that — it tells you, for every shot you hit, whether you gained or lost ground compared to a baseline.
How it works
Strokes Gained compares the expected number of shots from your starting position to your finishing position, minus one (for the shot you just hit).
If a scratch golfer averages 2.8 shots to hole out from 150 yards in the fairway, and you hit a shot from 150 to 20 feet (where the average is 2.0 shots), you gained 0.8 strokes on that shot.
That's it. Every shot is graded against a benchmark — usually PGA Tour average or scratch — and you end up with a per-category breakdown:
- SG: Off the Tee
- SG: Approach
- SG: Around the Green
- SG: Putting
Why it beats traditional stats
Greens in regulation tells you nothing about why you missed. Did you miss because of a bad drive, a bad approach, or because you laid up? GIR doesn't know.
Strokes Gained does. It assigns the loss to the specific shot that cost you, which means your practice time can target the actual weakness instead of a symptom.
What to do with it
Track Strokes Gained over 5–10 rounds. The category with your worst SG average is where to focus practice. It's almost never what you think it is — most amateurs assume putting is the problem when approach play is actually costing them more.
The point isn't to obsess over stats. It's to stop guessing. SG turns golf improvement from intuition into a feedback loop.
