Strokes Gained Explained

One Idea That Rewired Golf Statistics

This is the analytical engine under almost everything else on the site. The bogey-avoidance math in How To Break 90 and How To Break 80, the strategy rules in Course Management, and the practice priorities in Putting Practice all trace back to what strokes gained revealed about where shots are really won and lost.

The Expected-Strokes Idea, With Real Numbers

The whole system rests on one table: the average strokes a benchmark golfer needs to hole out from any given distance and lie. Mark Broadie built that table from millions of PGA Tour shots. A few well-known landmarks make it concrete.

Now watch a shot earn its number. You stand on a 400-yard par 4 worth 4.0 expected strokes and hit a drive to 140 yards in the fairway, a spot worth about 2.85. Your strokes gained off the tee is 4.0 minus 2.85 minus the one stroke you played, which is plus 0.15. A solid, slightly better-than-average drive. Hole the 33-foot putt that follows and you gain 2.0 minus 1.0, a full plus 1.0 in putting, because the field two-putts from there almost every time. Two-putt it and you gained exactly zero: you did precisely what was expected.

The Four Categories

The PGA Tour splits every non-putting shot by where it starts, then adds putting, giving four buckets that sum to Strokes Gained: Total. Off the Tee, Approach and Around the Green together form Strokes Gained: Tee-to-Green, the long-game total that analysts trust most.

Notice that the categories are defined by where the shot starts, not what club you used. A 60-yard wedge from the fairway is an approach shot; a 20-yard pitch is around the green. That clean boundary is what lets the four numbers add up cleanly to your total.

Where It Came From: Broadie, ShotLink And A 2011 Launch

Strokes gained is the work of one man and one dataset. Mark Broadie, a professor at Columbia Business School and a serious amateur golfer, had been modelling golf with an expected-value lens for years when the PGA Tour's ShotLink system gave him the raw material: the precise location of every shot at Tour events, captured by laser since the mid-2000s.

• 2011: Strokes Gained Putting launches. Working with Broadie's method, the Tour replaced crude putting stats with a measure that compared every putt to the field's make and two-putt rates from the same distance. For the first time, holing a 25-footer counted for more than tapping in from two feet.
• 2014: Every Shot Counts and Tee-to-Green. Broadie published his book Every Shot Counts, laying out the full framework, and the Tour added Strokes Gained: Tee-to-Green to capture the long game in a single number.
• 2016: the long game splits into three. The Tour broke Tee-to-Green into Off the Tee, Approach and Around the Green, the four-category model used everywhere today.
• Now: standard everywhere. Strokes gained is built into Tour broadcasts, betting models, coaching software and consumer apps. It is the common language of modern golf analysis.

Broadie is often called the godfather of golf analytics, and the comparison to baseball's sabermetrics revolution is fair: like on-base percentage in baseball, strokes gained exposed how much the traditional box score had been hiding.

Why It Beats Fairways, Greens And Total Putts

The old stats were not wrong so much as blind. They counted events without weighing how hard those events were, and that blindness flattered the wrong players.

• Fairways hit ignores distance. It scores a 250-yard lay-up in the fairway as a success and a 330-yard bomb into the first cut as a failure, even though the bomber usually has the easier next shot. Strokes Gained: Off the Tee values the position you actually left yourself.
• Greens in regulation ignores proximity. Hitting a green to 40 feet and to 4 feet both count as one green, yet one is a likely par and the other a likely birdie. Strokes Gained: Approach rewards how close you got.
• Putts per round punishes good iron play. A player who fires approaches to 12 feet faces more makeable putts and often more total putts than someone who misses greens and chips close. The old stat made the better ball-striker look like a worse putter. Strokes Gained: Putting, judged by distance, fixes the injustice.

What The Data Actually Says: Approach Is King

The most important finding from Broadie's work overturned decades of received wisdom. The old saying was "drive for show, putt for dough." The data says the opposite: the long game pays.

Across the Tour, the long game (off the tee plus approach) explains roughly two-thirds of the scoring difference between players, and approach play is the single largest piece of that. Putting accounts for only about 15 percent of the gap among elite professionals. A red-hot putting week can absolutely win a tournament, which is why putting feels decisive in the moment, but over a season and a career the players who separate themselves do it with their ball-striking, above all their irons.

That is the analytical reason this site keeps steering practice toward approach quality and disaster avoidance rather than the putting green that amateurs gravitate to. The same logic drives the Course Management playbook and the bogey-first math of How To Break 80.

Reading A Leaderboard Through Strokes Gained

Once you think in strokes gained, a Sunday leaderboard reads completely differently. The score tells you who is ahead; the category breakdown tells you whether they will stay there.

• Built on ball-striking (usually sticks). A leader who is strongly positive in Tee-to-Green and merely neutral on the greens is winning with the most repeatable skills in golf. That lead tends to survive four rounds.
• Built on putting (usually fades). A leader who is plus 4 in putting but negative tee-to-green is riding the most volatile category there is. Putting regresses week to week far more than ball-striking, so that name often slides over the weekend.
• The tell broadcasters now show. When a telecast flashes a player's four-category bars, it is answering the only question that matters: is this round real or borrowed? Strokes gained is the honest answer.

It is also why the modern betting and fantasy markets are built almost entirely on strokes gained history rather than scoring average: it predicts the future better than the scoreboard does.

The Rory Reference: McIlroy's Driver Versus Scheffler's Irons

The two best players of this era are a perfect strokes-gained case study, because they are elite in different boxes. Reading their profiles tells you more about each man than any highlight reel.

Scheffler is the more complete tee-to-green machine and, after a much-noted improvement on the greens, the steadier putter of the two of late. McIlroy's separator is the driver: when he is on, no one in the world gains more off the tee, and that advantage was central to the back-to-back 2025 and 2026 Masters wins that completed his career Grand Slam. Neither man got there by chasing putts. Both prove the lesson strokes gained taught the whole sport: you win at the top by being elite at the long game.

How Amateurs Track Their Own Strokes Gained

The best part of the strokes-gained era is that it is no longer just for the Tour. Two consumer systems put the same math in your pocket, benchmarked to your target handicap rather than to Scottie Scheffler.

• ArccosSmall sensors screw into the butt of each grip and pair with your phone (or the Arccos Link clip, or an Apple Watch). The sensor announces which club just struck a ball and GPS logs where, so the app sorts every shot into drive, approach, chip or putt automatically. A sensorless option, Arccos Air, uses a wearable's motion sensors instead. You get a four-category strokes-gained breakdown against your handicap target within a handful of rounds.
• Shot ScopeA GPS watch plus lightweight tags in the grip end; no phone needed on the course, everything records to the watch and syncs afterward. The post-round dashboard runs well over 100 stats, including strokes gained by category and detailed club distances, which is gold for sorting out gapping.
• What you will probably learnThe same surprise almost everyone gets: the weakness is not where you thought. Most amateurs who track discover their biggest leak is approach play or penalty-strewn driving, not the putting they spend their range time on. The data redirects your practice to the change that actually lowers your score.

If you want the gear context around these trackers, the Golf GPS Watches and Golf Rangefinders guides cover how distance tech fits alongside shot tracking.

Common Misconceptions

• 1. "Strokes gained is just a putting stat." It started with putting in 2011 but now covers the whole game in four categories. The long game is where it matters most.
• 2. "A positive number means you played well." It means you beat the benchmark, usually the Tour field. An amateur measured against the Tour will be deeply negative while playing a fine round; the point is the comparison group.
• 3. "Putting is where tournaments are won." Putting wins individual weeks because it is volatile. Careers are built on approach play, which is roughly the most predictive category of sustained success.
• 4. "Fairways hit still tells me about driving." It tells you almost nothing without distance. Strokes Gained: Off the Tee is the honest measure, and it often ranks long-and-crooked above short-and-straight.
• 5. "It needs Tour lasers to work." Consumer apps approximate the same baselines well enough to be genuinely useful. You do not need ShotLink to find your own biggest leak.
• 6. "Total is the only number that matters." Total tells you the result; the category split tells you why, and the why is what you practise. Tee-to-Green is the more predictive headline number.
