Strokes Gained Explained for Amateur Golfers

What Is Strokes Gained?

Strokes gained is a statistical framework that measures how many strokes a golfer gains or loses in each part of their game compared to a baseline. Originally developed by Columbia professor Mark Broadie and adopted by the PGA Tour, strokes gained replaced the old way of looking at golf stats in isolation (fairways hit, putts per round, etc.) with a system that shows the actual impact of each skill on your score.

The key insight: a stat like “30 putts per round” means nothing without context. A player who hits 15 greens and takes 30 putts is putting brilliantly. A player who hits 6 greens and takes 30 putts is putting terribly — most of those putts came from off-green scramble situations with shorter first putts. Strokes gained accounts for this context.

Why Peer Benchmarking Matters

Most strokes gained tools compare you to PGA Tour averages. This is almost useless for a 15-handicap golfer. Of course you lose strokes to Tour pros in every category — you already know that. The useful question is: “Compared to other 15-handicap golfers, where am I gaining and losing strokes?”

Peer benchmarking reveals actionable patterns. If you're a 15-handicap who putts like a 10-handicap but scrambles like a 20-handicap, your putting is a strength and your short game is the bottleneck. A Tour-based comparison would tell you everything is bad — not helpful for deciding what to practice.

Golf Data Viz compares you against golfers in your own handicap bracket using aggregate data from Shot Scope, Arccos, and other published amateur sources. See our benchmark data by handicap for the exact numbers.

The Four Strokes Gained Categories

Strokes gained breaks your round into four categories, each covering a distinct part of the game:

1. Off the Tee (SG: OTT)

Measures your tee shot performance — primarily fairway hit rate and penalty avoidance. In scorecard-based models like ours, Off the Tee captures driving accuracy rather than distance (which requires shot-tracking hardware).

A positive SG: OTT means you hit more fairways and take fewer penalties than your handicap peers. A negative value means you're losing strokes off the tee compared to similar golfers.

2. Approach (SG: APP)

Measures your ability to hit greens in regulation. This is often the most impactful category for mid-handicap improvement — hitting more greens creates easier birdie and par opportunities while reducing scrambling pressure.

Approach is measured by your GIR percentage compared to your peers. If you're a 12-handicap hitting 8 greens per round when peers average 6, you're gaining significant strokes on approach.

3. Around the Green (SG: ATG)

Measures your short game — specifically, how often you get up and down when you miss a green. Scrambling percentage (converting a miss into a par save) is the primary driver.

Many amateur golfers underestimate the impact of their short game. A strong scrambler can offset weak approach play, while a poor scrambler amplifies the damage of every missed green.

4. Putting (SG: PUTT)

Measures putting efficiency relative to your peers. True shot-level putting SG uses putt starting distances; our scorecard-based model uses a GIR-adjusted approach that accounts for whether you're putting from the green (longer first putts, birdie attempts) or from scramble situations (shorter first putts, par saves).

Common Misconceptions

“Putting is the most important part of the game”

Conventional wisdom says putting is half the game because roughly half your strokes are putts. But strokes gained research consistently shows that for most amateurs, the biggest scoring gaps are in approach play and short game — not putting. Putting differences between handicap brackets are relatively small compared to GIR and scrambling differences.

“My putts-per-round number tells me how I putt”

Putts per round is a misleading stat because it doesn't account for GIR. A player who hits 14 greens will have more putts than a player who hits 5 greens — but the first player is almost certainly putting better. Strokes gained adjusts for this by comparing expected putts based on your GIR rate.

“Scorecard SG is the same as Tour SG”

True strokes gained (as used on the PGA Tour) measures every shot's start and end position against expected strokes from that location. This requires GPS or shot-tracking devices. Scorecard-based SG uses aggregate round stats (fairways, GIR, putts, scoring) to estimate category performance. It's directionally useful for practice prioritization but less precise than shot-level analysis. Read the full comparison in our methodology.

How to Use Your Results

After running your round through the calculator, look for the category with the most negative strokes gained value — that's where you're losing the most ground to your peers and likely the highest-leverage area for practice.

Also pay attention to your strengths. Knowing what you do well helps you build a game plan around your advantages. A golfer who gains strokes putting but loses them on approach might benefit more from iron work than putting drills.

Run multiple rounds through the calculator to see patterns. Single-round results can be noisy — a trend across 3-5 rounds gives you a much clearer picture of where to focus.
