- SG: Approach is the single largest source of lost strokes for most amateur golfers, often accounting for 30-40% of total strokes lost to scratch
- The metric captures approach shots from 100+ yards, including par 3 tee shots and long iron/hybrid shots into par 5s
- Distance control (not direction) is the primary weakness -- amateurs consistently come up short
- Improving SG: Approach has the highest downstream impact because hitting more greens reduces short game and putting pressure
Why Approach Shots Matter More Than You Think
If you could magically improve one part of your game overnight, which would give you the lowest score tomorrow? Most golfers would say putting. The data says approach play, and it's not even close.
Mark Broadie's research showed that approach shots account for the largest share of scoring difference between amateurs and scratch golfers. A 15-handicapper typically loses 4-5 strokes per round on approach compared to scratch. For a 20-handicapper, it's 6-7 strokes. Meanwhile, putting differences are usually 2-4 strokes across the same range.
Why the gap? Approach shots are hard. They combine distance control, directional accuracy, lie assessment, club selection, and trajectory management all in one shot from a variety of distances. When any one of these elements goes wrong, the result can be dramatically bad.

How SG: Approach Is Calculated
SG: Approach covers any shot from 100+ yards that isn't a tee shot on a par 4 or par 5. This includes:
- Iron shots into par 4 greens
- Tee shots on par 3s
- Second and third shots into par 5 greens
- Long approach shots from the rough or fairway
The calculation compares your shot's outcome (where the ball ends up) against the baseline expected strokes from your starting position. Hit your approach from 160 yards to 15 feet on the green? You gained strokes. Hit it from 130 yards into a greenside bunker? You lost strokes. The baseline accounts for the specific distance and lie.
The #1 Amateur Approach Problem: Coming Up Short
If there's one pattern that dominates amateur SG: Approach data, it's this: most golfers miss greens short. Not left, not right, not long. Short.
This happens for three interconnected reasons:
You don't know your real distances. When you hit your 7-iron 155 yards that one time on a downwind, downhill shot, that became "your 7-iron distance" in your head. Your actual average carry is probably 140-145. The gap between perceived and actual distance is 10-15 yards for most amateurs.
You pick the club for a perfect strike. Tour pros pick the club that reaches the target on their average strike, not their best strike. Amateurs pick the club that works when they flush it. Since you don't flush it every time, you come up short more often than not.
Greens are designed to penalize short misses. Course architects put bunkers, slopes, and tight lies in front of greens far more than behind them. A shot that lands 10 yards short faces a much harder up-and-down than one that lands 10 yards long.
NG Choosing your 7-iron for 155 because you 'can hit it that far'
OK Choosing your 6-iron for 155 because your 7 averages 145 and the miss is more forgiving long
What Good SG: Approach Looks Like at Different Levels
The differences are stark. Compared to the PGA Tour baseline:
- Scratch golfer: roughly even (0 SG: Approach)
- 5 handicap: loses about 2 strokes per round
- 10 handicap: loses about 3-4 strokes per round
- 15 handicap: loses about 4-5 strokes per round
- 20 handicap: loses about 6-7 strokes per round
Every improvement in this category has a multiplying effect. When you hit more greens, you face fewer scramble situations, which means fewer difficult chips and pitches, which means fewer three-putts from long lag putts. One better approach shot can save you 1.5 strokes on that hole by preventing a chain of recovery shots.
How to Improve Your SG: Approach
Map your real carry distances
On the range or course, record the carry distance of 10 shots with each iron. Throw out the best and worst two. The middle six are your actual average. You'll probably be surprised how much shorter it is than you thought.
Club up one on every approach
As a simple rule, take one more club than you think you need for every approach shot. This alone eliminates the single biggest source of amateur approach misses -- coming up short.
Aim center-green, not at the pin
Unless the pin is in the middle of the green with no trouble nearby, aim for the center. A 25-foot putt from the middle of the green is almost always better than a bunker shot from short-siding yourself.
Practice specific distances, not just 'iron work'
Instead of hitting 30 balls with your 7-iron, hit 5 balls each at 120, 130, 140, 150, 160, and 170 yards. This trains distance control, which is the skill that actually matters for approach play.
The Downstream Effect
Here's what makes SG: Approach improvement so powerful: it doesn't just save you strokes on approach shots. It saves strokes everywhere.
When you improve from 4 GIR per round to 8 GIR per round, that's 4 fewer holes where you need to chip and putt for par. Even if your short game is average, you'll save 2-3 additional strokes per round just by having fewer scramble attempts. And the putts you face will be longer on average (because you're putting from the green instead of chipping close), but they'll be easier putts -- flat, on the green, with a predictable surface.
This compounding effect is why coaches and analysts call SG: Approach "the biggest lever in golf." It's the one category where improvement ripples outward to improve everything else.
NG Spending 70% of range time hitting driver and 10% on irons
OK Spending 50%+ of range time on iron accuracy and distance control, where the scoring leverage is highest
The Bottom Line
SG: Approach is probably where your game loses the most strokes, and it's almost certainly where you spend the least practice time relative to the opportunity. Know your real distances, club up, aim smart, and practice distance control. The data is overwhelming: improving your approach play is the fastest, most reliable path to lower scores.
