What Is Strokes Gained Off the Tee? A Plain-English Definition
Strokes gained off the tee sounds technical, but the meaning is simple: it scores your driver and fairway wood tee shots against what a benchmark golfer would do from the same spot.
Strokes gained off the tee (written SG:OTT) measures how much your tee shots on par 4s and par 5s help or hurt your score compared to a benchmark player from the same spot. The strokes gained off the tee meaning comes down to one idea: a single number that tells you whether your driving is gaining you strokes or quietly losing them.
This post answers the literal question — what the term means, which shots count, and how to read the number. If you want the full breakdown of how to act on it, read our deep dive on strokes gained off the tee afterward.
The Strokes Gained Off the Tee Meaning, Defined
The phrase splits into two parts. Strokes gained is the framework Mark Broadie built to compare any shot against the expected number of strokes a benchmark golfer needs from a given position. “Off the tee” narrows that framework to one shot type: your opening shot on the longer holes.
Put together, SG:OTT answers a focused question. From the tee box, did your drive leave you better or worse off than the benchmark would have been? Add up every counted tee shot in a round and you get your SG:OTT for that round.
A positive number means your tee game gained strokes on the benchmark. A negative number means it lost strokes. Zero means you matched the benchmark exactly.
What Counts as “Off the Tee”
SG:OTT only includes tee shots on par 4s and par 5s. Your tee shot on a par 3 does not count here — because you are aiming straight at the green, it is classified as an approach shot instead.
That distinction matters. In a standard round with four par 3s, you have 14 tee shots feeding into SG:OTT. If your overall strokes gained looks weak off the tee, the issue is your driver and fairway wood on long holes, not your iron play on the short ones.
A Simple Example
Numbers make this concrete. You are on the tee of a 400-yard par 4. A benchmark golfer is expected to need about 4.10 strokes to hole out from there.
You hit a drive 260 yards into the fairway, leaving 140 yards to the pin. From 140 yards in the fairway, the benchmark needs about 2.85 strokes.
Your strokes gained on that one shot is 4.10 − 2.85 − 1 = +0.25. You used one stroke, the situation improved by more than the benchmark expected, so you gained a quarter of a stroke.
Now hit that same drive 220 yards into the left rough, 190 yards out. From 190 yards in the rough the benchmark needs about 3.80 strokes. Your strokes gained is 4.10 − 3.80 − 1 = −0.70. One short, crooked drive just cost you most of a stroke. Over 14 tee shots, those swings add up fast.
How to Read Your SG:OTT Number
Per-round SG:OTT is easiest to interpret against a PGA Tour baseline:
| SG:OTT per Round | What It Means |
|---|---|
| +1.0 or higher | Driving is a genuine weapon |
| -0.5 to +1.0 | Around Tour average |
| -1.5 to -0.5 | Below average, leaking about a stroke per round |
| Below -1.5 | Your tee game is a major scoring drain |
Most amateurs show large negative numbers against a Tour baseline, and that is normal. A 15-handicap typically sits around -2.0 to -3.0 off the tee. That gap is not a flaw in the stat; it reflects how much distance and accuracy separate amateur driving from Tour driving. For a fairer read, compare yourself to a level closer to your own using benchmarks by handicap.
Why It Beats Fairways Hit and Driving Distance
Most golfers judge their tee game with two stats, and both tell half the story.
Fairways hit treats a 5-iron layup the same as a 300-yard bomb, and it cannot tell a 290-yard drive that trickles into the first cut apart from a snap hook into the trees. One of those is fine; the other costs a stroke.
Driving distance only records how far the ball traveled, ignoring where it stopped. A 280-yard average that finds the rough 60% of the time can score worse than a 250-yard average that stays in the short grass.
SG:OTT fixes both problems by weighing distance and lie at the same time. It does not care how you got there — it measures the outcome relative to the difficulty of the next shot. That is why it is a sharper read on driving than fairways hit or distance alone.
See Your Own Off-the-Tee Number
golfity calculates SG:OTT automatically from the shots you log — no GPS hardware or launch monitor required. Record where each tee shot started and finished, and the app runs the expected-strokes math for you. You can also test single shots in the strokes gained calculator to feel how distance and lie move the number.
After about 15 rounds your off-the-tee data stabilizes enough to trust. At that point you will know, in one number, whether your driver is a strength or the place where your scores are slipping away.
