What Does SG Off the Tee Mean in Golf?

By Spencer Lanoue
November 2, 2025

Ever pull a perfect-looking drive down the middle, only to have your golf buddy, who bombed it 40 yards past you into the light rough, make an easier birdie? It's a frustrating moment that reveals a fundamental truth: not all drives are created equal. This is where Strokes Gained: Off the Tee, one of the most powerful stats in golf, steps in to clarify what really matters. This article will break down exactly what SG: Off the Tee means, why it’s a better measure of performance than just fairway percentage alone, and how you, as a player, can use this knowledge to start making smarter, more effective decisions at the tee box.

So, What Exactly Is Strokes Gained? A Quick Overview

Before we can master the tee box, we first need to get a grip on the core concept of "Strokes Gained." Think of it as a way to measure the quality of every single shot you hit. The system, developed by Columbia University professor Mark Broadie, uses extensive data from the PGA Tour to establish a baseline number of strokes it should take a professional to hole out from any distance and lie on the course.

Here’s a simple comparison:

  • From 10 feet on the green, the PGA Tour average is 1.5 strokes to get the ball in the hole. This factors in all the made putts, two-putts, and even the occasional three-putt.

Now, let's see how our shots get measured:

  • If you one-putt from 10 feet, you took 1 stroke. Comparing that to the average (1.5), you gained half a stroke on the field (1.5 - 1 = +0.5 SG). Great job!
  • If you two-putt from 10 feet, you took 2 strokes, it means you lost half a stroke against the field (1.5 - 2 = -0.5 SG).

This same logic applies to every part of the game - putting, approach shots, short game, and, of course, driving. It provides a precise decimal value to how much each shot helped or hurt your final score, moving far beyond outdated stats like "Greens in Regulation" or "Fairways Hit."

An In-Depth Look at SG: Off the Tee

Now we get to the main event. Strokes Gained: Off the Tee (SG:OTT) specifically measures your performance on every par-4 and par-5 tee shot relative to a scratch golfer or PGA Tour baseline. It’s the ultimate measure of your driving prowess because it accounts for both distance and accuracy in a beautifully simple number.

Tee shots on par-3s are not included here, as any of those shots are categorized as approach shots, given the intent is to hit the green.

How it’s Calculated (A Relatable, Clear Example)

Let's play a 420-yard par-4. The tour baseline indicates that from the tee marker it should take an average of 4.10 strokes to hole out.

Scenario 1: The Long and Straight Drive

  1. You mash a perfect drive 290 yards straight down the fairway.
  2. Your next shot is from the fairway, 130 yards out. The statistical baseline to hole out from that specific spot (fairway, 130 yards) is 2.95 strokes.

Now, let's calculate our SG: Off the Tee figure with this simple formula:

(Starting Stroke Value) - (Ending Stroke Value) - 1 (for the shot taken) = SG:OTT

Plugging in our values for this particular shot:

4.10 - 2.95 - 1 = +0.15 SG: Off the Tee

You gained 0.15 strokes on the field with that single tee shot. You set yourself up for an easier approach and a better chance at birdie because you hit a very high-quality drive.

Scenario 2: The Short Drive in the Rough

On the very same hole, this time let’s imagine you hit a weak slice.

  1. Your drive travels only 220 yards and lands in the thick rough.
  2. Now, your next shot is from the heavy rough, 200 yards out. That's a much more difficult proposition, right? The statistical baseline to hole out from this difficult location is 4.20 strokes.

Once again, let's plug those new digits into our tried-and-true formula:

4.10 - 4.20 - 1 = -1.10 SG: Off the Tee

This one hurt. The tee shot cost you over a full stroke against the competition. You not only lost a lot of distance, but you also put yourself in a tough spot to recover from, which is much more likely to end in a bogey or worse. This quantifies exactly how bad it was compared to our first, successful tee shot.

Why SG: Off the Tee Is a Golfing Game-Changer

Simply tracking whether you hit the fairway or not is a relic from the past. It doesn't tell the whole story. SG: Off the Tee helps us uncover what truly impacts your score from the tee box.

It Accurately Values Distance

For decades, golf wisdom preached "drive for show, putt for dough." SG: Off the Tee has completely debunked this. Data shows without compromise that distance is a massive advantage. Our examples clearly illustrate why that buddy who bombed his drive 40 yards past you - even if he was in the first cut of rough - was in a far better position. Hitting a 5 wood vs. wedge to the green are completely different propositions.

It Reveals Your True Weaknesses and Your Real Strengths

Are you losing strokes off the tee because you're consistently out of play, taking penalty strokes? Or is it that your average drive, despite being dead straight at the fairway, is always 40 yards shorter than the other people playing with you? SG: OTT will give clear and straight answers to these critical questions. By tracking this metric over several rounds, you won’t just have a ‘feeling’ about your driving performance, you’ll have hard data pointing to what needs to be fixed immediately.

Informs Smarter Strategy on The Course and Your Practice

When you learn that landing in the right rough may only carry a penalty of about 0.2 strokes, while an out-of-bounds yields a penalty of two full strokes, what do you think your decisions as a player on the next round will be? SG: OTT encourages you to start thinking in terms of probability and risk-reward. On a hole with water all down the left and more room to bail out on the right side, you’ll learn that it’s completely fine and in most cases very strong to aim a little further right and take your chances with the rough to avoid the huge penalty of the dreaded water hazard. Smart strategizing will help you to be a pro when approaching even the most difficult hazards out there!

How to Improve Your SG: Off the Tee: Coach's Corner

Knowing the "what" and "why" is great, but as a coach, I'm more interested in you having actionable advice and taking action. Let's get to the 'how.' Here are three proven ways to start adding positive numbers to your SG: Off the Tee column.

1. Swing for Controlled Speed, Not Reckless Power

Gaining yards definitely matters. More clubhead speed is one of the easiest ways to do it. The goal is to maximize your speed without losing consistency, which would only lead to more negative SG numbers. Instead, you need to generate speed by using your body rotation more instead of your arms:

  • Master Body Rotation: Often, amateurs try to generate more swing speed with their arms alone, leading to poor performance and low confidence on the golf course. You need to use your biggest muscles in sync. The rotation from your upper body and lower hips provides real power. As you begin your downswing, focus on unwinding your hips and torso first, allowing your arms and club to follow this powerful rotation, leading to more speed generation.
  • Get Comfortable with a 'Go-To' Shot: Hitting the ball perfectly straight every single time is unrealistic. Even the best players in the world have a preferred swing shape, a draw or a fade. Pick the one you feel more comfortable with, and now you know the direction your swing often goes, giving you confidence and a better shot next time.

2. Become the Master of the Center-Face Strike (Smash Factor!)

The single most efficient power source you can have immediately in golf is the centeredness of your shots. Hitting the ball even half-an-inch toward the heel or toe can cost you as much as 6-8 mph of your ball speed, equating to lost distance and inconsistent flights. Don't worry, I have the right drill for you to practice immediately...

A Must-Have in Your Golf Bag: The Foot Spray Drill. Get yourself a can of aerosol foot spray and apply a thin layer to the face of your driver when you're in the training facility. Hit five balls and examine the resulting mark. You'll immediately know where you had most of the contacts. Was it towards the heel or the toe? The feedback is immediate and undeniably powerful in knowing how you can improve your swing. Now all you have to do next is try different swings to make it to the center as much as you can...

3. Use Strategic Aggression

Driving long and straight is important, but driving smart is paramount. A good driver of the golf ball recognizes the risk and reward of each shot and the course they are playing on and decides on an effective strategy to place themselves in the best position.

  • Assess the Trouble: Look at the hole from the tee box and assess it carefully before you swing away. Where are the no-go zones on the course, like the heavy rough, a huge bunker, or water or out-of-bounds? All these bad areas represent a huge SG penalty. Once you identify them, find your safe spot or a "miss zone" where an offline shot won't have a big consequence. Aim to the wide part of the fairway as a smart and good strategy to apply day in and out.
  • Select Your Club Accordingly. Don't make the mistake of pulling out your driver no matter which hole you're on from the tee box. Think about the hazards you need to avoid like we discussed earlier, now you know them better, and which one could have the biggest SG penalty. Maybe it's smarter to use a 3-wood or even a long iron to avoid that huge penalty and stay safe, ensuring a better score in the end.

Understanding and applying the principles of Strokes Gained: Off the Tee is a revolutionary way to improve your game and have a smarter and winning start at the tee box of your favorite golf course.
