Understanding Strokes Gained Off the Tee
Your tee shot on par 4s and par 5s sets the tone for everything. Strokes gained off the tee is the only metric that captures both distance and accuracy in a single number.

Every round starts from the tee box. On par 4s and par 5s, that opening shot determines whether you’re attacking the green from 140 yards in the fairway or hacking out from behind a tree. Strokes gained off the tee (SG:OTT) is the metric that quantifies this—measuring both how far and how straight you hit it, in a single number.
If you’ve read our guide to strokes gained categories, you know the basics. Here we’ll get into what SG:OTT actually captures, what the benchmarks look like at different handicap levels, and how to act on your numbers.
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 is classified as an approach shot, because you’re aiming directly at the green. This distinction matters. If your overall strokes gained looks weak off the tee, the problem is specifically your driver and fairway wood game on longer holes, not your iron play on short ones.
In a standard 18-hole round with four par 3s, you’ll have 14 tee shots counted toward SG:OTT. Each one gets measured against a baseline: what would a scratch golfer (or PGA Tour player, depending on your benchmark) expect to score from the same starting position?
How the Calculation Works
Mark Broadie’s research established expected strokes values for every position on a golf course, based on distance to the hole, lie type (fairway, rough, sand, recovery), and proximity to the green.
Here’s a concrete example. You’re on the tee of a 400-yard par 4. The expected strokes from the tee is about 4.10 for a scratch golfer. You hit your drive 260 yards into the fairway, leaving 140 yards to the pin. The expected strokes from 140 yards in the fairway is roughly 2.85.
Your strokes gained on that tee shot: 4.10 - 2.85 - 1 = +0.25 strokes gained.
You used one shot and reduced the expected strokes by 1.25 (from 4.10 to 2.85). Since you “should” have reduced it by exactly 1.0 with one shot, you gained 0.25 strokes over the baseline.
Now imagine you hit that same drive 220 yards into the left rough, 190 yards from the pin. Expected strokes from 190 yards in the rough might be about 3.80.
Your strokes gained: 4.10 - 3.80 - 1 = -0.70 strokes gained.
That short drive into the rough cost you 0.70 strokes compared to the baseline. Over 14 tee shots, these values add up fast.
What Your SG:OTT Numbers Mean
Here’s how to interpret your average SG:OTT per round, using PGA Tour baselines:
| SG:OTT per Round | What It Means |
|---|---|
| +1.5 or higher | Top-tier driving. Rory McIlroy territory. |
| +0.5 to +1.5 | Strong driver of the ball. Driving is clearly a weapon. |
| -0.5 to +0.5 | Tour average range. Solid, not spectacular. |
| -1.0 to -0.5 | Below average. Losing about a stroke per round from the tee. |
| -2.0 to -1.0 | Significant weakness. Distance, accuracy, or both need work. |
| Below -2.0 | Driving is your biggest scoring leak. |
For amateur golfers using a scratch baseline, the numbers shift. A 15-handicap typically shows SG:OTT around -2.0 to -3.0. A 10-handicap sits closer to -1.5. Single-digit players hover around -0.5 to -1.0. Check your handicap-specific benchmarks for context.
Why Traditional Tee Stats Mislead You
Most golfers track two things off the tee: fairways hit percentage and driving distance. Both tell incomplete stories.
Fairways hit treats a 5-iron layup to the center of the fairway the same as a 300-yard drive that catches the edge. It also penalizes a 290-yard drive that rolls two feet into the first cut exactly as much as a snap hook into the woods. One of those is fine; the other costs you a stroke. Fairways hit can’t tell them apart.
Driving distance only measures how far the ball went, ignoring where it ended up. A golfer who averages 280 yards but finds the rough 60% of the time might actually score worse off the tee than someone averaging 250 yards in the fairway.
SG:OTT solves both problems. It accounts for distance and lie simultaneously. A 280-yard drive into light rough might be worth +0.1, while a 250-yard drive in the fairway could also be +0.1. The metric doesn’t care about your method. It measures the outcome relative to the difficulty of what comes next.
The Distance vs. Accuracy Trade-Off
Here’s something Mark Broadie’s research revealed that surprised a lot of golfers: distance matters more than accuracy off the tee, on average.
On the PGA Tour, the correlation between driving distance and scoring is stronger than the correlation between driving accuracy and scoring. The reason is mathematical: moving 30 yards closer to the hole from the rough is often more valuable than being in the fairway but 30 yards farther back.
This doesn’t mean accuracy is irrelevant. A drive into the trees or a penalty area is devastating. But the data shows that moderate misses (first cut, light rough) cost much less than most golfers assume. The big penalty comes from severe misses: out of bounds, deep woods, water.
For a 15-handicap, the math often works like this:
- Hitting driver and averaging 240 yards (55% fairways): SG:OTT = -2.1
- Hitting 3-wood and averaging 215 yards (70% fairways): SG:OTT = -2.6
The extra distance wins, even with fewer fairways. Your mileage varies based on the severity of your misses, but the general principle holds across most skill levels.
How to Improve Your SG:OTT
Your golfity data can point you in the right direction. Here’s how to dig in.
Check Your Penalty Rate
Sort through your worst tee shots. If you’re losing big strokes on a few holes (penalty strokes, punch-outs from the trees), your priority is eliminating those disaster shots. Fixing two -1.5 tee shots per round has more impact than slightly improving ten average ones.
Compare Distance vs. Lie Outcomes
In golfity, look at where your tee shots end up. If most of your drives land in the fairway or light rough at reasonable distances, your OTT game is probably acceptable. If you’re frequently in heavy rough, bunkers, or hitting provisionals, accuracy is the issue.
Look at Your SG:OTT Trend
Track this number across 10-20 rounds. A sample size of 5-6 rounds isn’t enough for stable SG:OTT numbers. You need around 15 rounds before the category-level data stabilizes. Short-term swings are mostly noise.
Consider Course Context
SG:OTT varies by course design. Tight, tree-lined courses will produce lower OTT numbers for everyone. Wide-open links courses will inflate them. Compare your OTT numbers across similar course types rather than mixing everything together.
SG:OTT in the Bigger Picture
Off the tee is typically the second most important strokes gained category for scoring, behind approach play. Mark Broadie’s data from the PGA Tour shows that the spread in SG:Approach between the best and worst players is wider than SG:OTT. For amateurs, the gap is even larger—approach shots account for the biggest chunk of strokes lost.
That said, a bad tee shot makes everything harder. You can’t hit a good approach from behind a tree. The categories interact: improving your driving by +0.5 strokes per round often improves your approach numbers too, because you’re hitting from better positions.
This cascading effect is why elite players who gain strokes off the tee tend to gain everywhere else too.
Start Tracking Your Tee Game
The only way to know your real SG:OTT is to track every shot. golfity calculates it automatically. Record your tee shots during the round, and the app handles the expected strokes math in the background.
Once you have 15+ rounds of data, you’ll have a reliable picture of where your tee game stands. From there, you can build a practice plan that targets the right things: more distance, better accuracy, fewer penalties, or some combination of all three.
Your driver might be your best club or your worst. Stop guessing and let the numbers tell you.
