- Strokes Gained measures the quality of every shot relative to a baseline, not just binary outcomes like "fairway hit" or "green hit"
- Approach shots (not putting) are where most amateurs lose the largest share of strokes
- You don't need tour-level tracking to benefit -- consistent stat recording across rounds reveals your real weaknesses
- Focusing practice on your worst SG category produces the fastest improvement
The Stat That Changed How Pros Think About Golf
If you've ever shot a decent score and felt like you played terribly, or posted a high number on a day your swing felt great, you've bumped into the limits of traditional golf stats. Fairways hit, greens in regulation, putts per round -- they each measure one isolated thing, and they miss the bigger picture.
That's the problem Columbia professor Mark Broadie set out to solve. His Strokes Gained framework, now used by every PGA Tour player and caddie, measures something fundamentally different: how each individual shot contributes to your overall score compared to a baseline.
Every shot you hit either gains strokes or loses strokes relative to what an average golfer would do from the same spot.
A Quick Example Makes It Click
You're 150 yards out. The average golfer takes 2.95 strokes to finish the hole from here. You hit your approach to 8 feet, where the average golfer needs 1.50 strokes to hole out. Your Strokes Gained on that approach:
SG = 2.95 - 1 (your shot) - 1.50 = +0.45
One shot, nearly half a stroke gained on the field. Stack those up over 18 holes and you have a precise picture of where your game stands -- and where it's bleeding.
Four Categories, One Complete Picture
| Category | What It Measures | Typical Shots |
|---|---|---|
| SG: Off the Tee | Tee shots on par 4s and par 5s | Driver, 3-wood |
| SG: Approach | Shots from 100+ yards (not tee shots) | Irons, hybrids |
| SG: Around the Green | Shots within 30 yards (not on green) | Chips, pitches, bunker |
| SG: Putting | All putts | Putter |
Your total Strokes Gained across all four equals your scoring difference from the baseline. No category gets hidden. No weakness goes undetected.
Why Traditional Stats Lie to You
Consider this scenario.
Golfer A hits 10 fairways, 7 greens, 30 putts. Looks fantastic on paper. But what if those fairways were reached with weak drives that left 200-yard approaches? What if those greens were hit to 40+ feet, and the "low" putt count came from short-siding and chipping close?
Golfer B hits 6 fairways, 4 greens, 34 putts. Looks mediocre. But those drives found the light rough with short approach distances. Every green was hit to 15 feet. The "high" putt count came from having more realistic birdie looks.
Traditional stats say Golfer A is better. Strokes Gained often reveals the opposite. It measures the quality of each shot, not just binary yes/no outcomes.

What a Typical Amateur's SG Looks Like
A 15-handicapper compared to scratch loses strokes across all four categories, but not equally. Approach shots typically account for the largest share -- around 5 strokes lost per round. Putting and around-the-green shots each contribute roughly 3.5-4 strokes. Off the tee accounts for about 2.5.
That's the counterintuitive insight Broadie's research surfaced: approach shots, the area most amateurs spend the least time practicing, tend to be their biggest scoring leak.
How to Start Using Strokes Gained Thinking
Track your stats consistently
Record score, fairways, GIR, putts, and penalties per round. Even basic data, accumulated over 10+ rounds, reveals meaningful patterns.
Identify your relative weakness
Which category loses you the most strokes compared to others at your handicap level? That's your highest-leverage practice area.
Practice where you lose the most
If SG: Approach is your worst category, prioritize iron practice and distance control. If SG: Putting is the weak link, spend more time on the practice green. Follow the data, not your assumptions.
Measure improvement over time
Watch your SG numbers trend across months. Small, sustained improvements in your weakest category compound into significant score drops.
NG Practicing driver because it's fun, even though your approach game is costing you 5 strokes a round
OK Checking your SG breakdown first and directing practice time to your weakest category
The Bottom Line
Strokes Gained is the gold standard for understanding your golf game. It cuts through the noise of traditional stats to reveal the true quality of your shots across all four categories. Find where you're losing the most strokes, direct your practice there, and watch the numbers move.
