What Is SG in Golf Stats?

Ever look at a pro’s round summary and see stats like SG: Off-the-Tee: +1.2 and SG: Putting: -0.8 and wonder what it really means? The Strokes Gained statistic has changed how professional and amateur golfers analyze performance because it moves past simple data to tell the true story of a round. This guide will walk you through what Strokes Gained is, how it works, and how you can apply its principles to find the real strengths and weaknesses in your own game.

What Exactly is Strokes Gained?

At its core, Strokes Gained measures your performance on every single shot relative to a benchmark, typically the average performance of PGA Tour players. A positive number means you performed better than the benchmark on that shot, while a negative number means you did worse.

Think about traditional stats for a moment. Metrics like "Fairways Hit," "Greens in Regulation," and "Putts Per Round" are useful, but they lack context. For example:

  • Is a 320-yard drive that misses the fairway and lands in the first cut of rough worse than a perfectly centered 240-yard drive?
  • If Player A misses every green but gets up and down for par, they'll have fewer putts per round than Player B who hits every green to 50 feet and two-putts. Who is the better putter?

Traditional stats can't answer these questions. Strokes Gained can. It accounts for the lie, the distance, and the situation of every shot. By the end of a round, you don’t just know what you did, you know how well you did it compared to a high-level standard. It identifies exactly where you are gaining an advantage or losing ground to your competition, whether that's off the tee, on approach shots, around the green, or on the putting surface.

A Simple Example: How Strokes Gained is Calculated

To really understand it, let’s walk through a single hole. The concept relies on a massive database that knows the average number of strokes it takes a PGA Tour pro to hole out from any distance and any lie (e.g., fairway, rough, bunker, green).

Let’s say you’re on a 420-yard par 4. The Tour average from the tee box on a hole of this length is 4.1 strokes.

  1. Your Tee Shot: You hit your drive 280 yards, leaving yourself 140 yards out in the fairway. The tour average to get in the hole from 140 yards in the fairway is 2.9 strokes.
    • Calculation: 4.1 (Start) - 1 (Your Shot) - 2.9 (End) = +0.2 Strokes Gained: Off-the-Tee. Congrats, you hit a great drive that gained you two-tenths of a shot on the field.
  2. Your Approach Shot: From 140 yards in the fairway, you hit your shot onto the green, leaving yourself a 30-foot putt. The tour average from 30 feet on the green is 2.0 strokes.
    • Calculation: 2.9 (Start) - 1(Your Shot) - 2.0 (End) = -0.1 Strokes Gained: Approach. This was a slightly below-average approach shot, costing you a tenth of a stroke.
  3. Your Putts: You are 30 feet away, and you two-putt for par.
    • Calculation: 2.0 (Start) - 2 (Your Putts) = 0.0 Strokes Gained: Putting. A two-putt from 30 feet is exactly Tour average. You neither gained nor lost strokes here.

On this hole, you made a par 4. Your total Strokes Gained for the hole would be:

+0.2 (OTT) - 0.1 (App) + 0.0 (Putting) = a total of +0.1 Strokes Gained for the hole.

You played the hole one-tenth of a shot better than a PGA Tour player would have on average. Now, imagine doing this for every shot in your round. That’s how you get a complete picture of your performance.

The Four Main Strokes Gained Categories

A round’s performance is broken down into four key areas. By looking at your numbers in each, you can stop guessing where you need to improve and start focusing your practice on the areas that are costing you the most shots.

1. Strokes Gained: Off-the-Tee (SG: OTT)

This category measures your performance on every tee shot on par 4s and par 5s. It powerfully combines distance and accuracy into one number. It recognizes that a long drive slightly in the rough can often be more valuable than a short drive in the fairway. A positive SG: OTT number means your driving is a weapon, setting you up for easier approach shots. A negative number could mean you're either too short, too inaccurate, or both, which puts pressure on the rest of your game.

  • Player Sign: Long hitters who consistently find the fairway or light rough excel here. Players who struggle with slices, hooks, or a lack of distance will see negative numbers.

2. Strokes Gained: Approach (SG: APP)

Many analysts consider this the most important a stat in golf. Itisolates the value of all your approach shots - shots from the fairway or rough aimed at the green. This also includes tee shots on par 3s. It measures your ability to control distance and accuracy with your irons and hybrids. Hitting an approach to 10 feet is obviously much better than hitting it to 40 feet, and SG: Approach quantifies that difference.

  • Player Sign: If your SG: APP is high, you're an excellent ball-striker who consistently gives yourself good birdie looks. If it's low, you're likely missing greens or leaving yourself long, difficult putts, making it very hard to score. Improving your iron play is one of the quickest ways to lower your handicap.

3. Strokes Gained: Around the Green (SG: ARG)

This stat covers your short game from within about 30-40 yards of the green, including chips, pitches, and bunker shots. It measures your ability to get the ball close to the hole from tricky spots. SG: ARG tells you how good your "scrambling" really is. A player with great hands and touch around the greens will post a positive number, saving par after a missed green. A player who struggles with chips (leading to fat shots or skulls) will lose a lot of strokes in this category.

  • Player Sign: A "short game wizard" - someone who often chips in or leaves tap-ins - will dominate SG: ARG. If your number is negative, you likely turn one mistake (missing the green) into two (a poor chip).

4. Strokes Gained: Putting (SG: P or SG: Putt)

Finally, a stat that tells you how good of a putter you really are. It measuresあなたのパッティングのパフォーマンスを指定された距離からベンチマークと比較します。(Measures your putting performance from a given distance compared to a benchmark). Instead of just counting total putts, it analyzes them. Was that a two-putt from 4 feet or from 60 feet? One is terrible, the other is excellent. SG: Putting knows the difference. One-putting a 20-footer gives you a big gain, while three-putting from 10 feet results in a significant loss.

  • Player Sign: Exceptional feel for speed and a great read on the greens will lead to high SG: Putting numbers. If you struggle with three-putts or frequently miss short putts, this is where you will see yourself hemorrhage strokes.

How Can You Use Strokes Gained to Improve?

You don't need a PGA Tour-sized statistical team to benefit from this way of thinking. Several consumer-level apps and GPS devices track Strokes Gained for amateurs, but even without them, you can adopt the mindset to guide your practice.

The first step is to change how you evaluate your game. Stop focusing on binary outcomes like "fairway hit" or "green missed." Instead, start paying attention to the quality of the outcome.

Here’s a simple mental checklist you can run after a round:

Driving Assessment:

  • Were my missed fairways still in good positions, or were they in punch-out territory?
  • Did my drives on par 5s leave me in a position to attack the green in two, or was I always laying up?

Your takeaway: Your goal isn't just to hit fairways, it's to advance the ball as effectively as possible to set up your next shot.

Approach Assessment:

  • When I missed greens, where did I miss them? Short-sided and in trouble, or in a place with an easy chip?
  • How many putts inside 15 feet did I have for birdie today? Five? One? None?

Your takeaway: The quality of your iron game isn't measured by GIR, but by the proximity to the hole of your good shots and the "miss" location of your bad ones.

Short Game & Putting Assessment:

  • Did I turn straightforward chips into tough 8-foot par saves, or easy tap-ins?
  • How many three-putts did I have? Were they from close range or long range? Missing a 4-footer is a huge mistake.

Your takeaway: Identify where the shots bleed away. Is it bad chipping that leaves you with testy putts, or poor putting from inside 10 feet? The answer tells you whether to take your sand wedge or your putter to the practice green.

By asking these context-rich questions, you are adopting the core principles of Strokes Gained analysis. You force yourself to identify not just what you did, but how well you did it, pinpointing the specific patterns holding you back.
