What counts as total bases in a bet?
Only hits count, and they count for how many bases the hit itself was worth: single 1, double 2, triple 3, home run 4. Walks, hit by pitch, stolen bases, reaching on an error and fielder's choice all count zero, no matter how far the runner ends up travelling.
Total bases counts one thing: the bases a hitter earned with the hit itself.
| Hit | Total bases |
|---|---|
| Single | 1 |
| Double | 2 |
| Triple | 3 |
| Home run | 4 |
That is the entire scoring system. Everything else in this article is about the cases where people expect a number and get a zero.
The zeros
Here is what returns nothing, no matter how it feels watching it:
- A walk. Not a hit. Zero.
- Hit by pitch. Not a hit. Zero.
- Reaching on an error. Not a hit. Zero.
- A fielder’s choice. Not a hit. Zero.
- A stolen base. The clue is in the name, and it is misleading. Total bases counts bases earned by the hit, not bases the runner ends up standing on.
- A sacrifice fly. Not a hit. Zero total bases, even though it drove in a run.
- Advancing on a wild pitch, a passed ball, or another hitter’s single. Zero.
The single most useful sentence in this article: a runner who singles and then steals second has one total base, not two. He is standing on second. The market does not care. The hit was worth one.
Your book publishes its own version of these rules and it is worth finding it before you need it rather than during an argument. DraftKings’ baseball rules are where we check.
Two real games
Jorge Polanco, 5 August 2026, against Tanner Bibee. Two hits. Six total bases. Two hits producing six bases means both went for extra bases. Our Under 0.5 total bases lost, and it finished at six rather than at the one a pair of singles would have produced.
Jonathan Aranda, same date, against Tomoyuki Sugano. One total base all game. Our Under 2.5 came in comfortably. He was not hitless, he was just not hitting for extra bases, and that is the distinction the market is actually pricing.
Why the market exists at all
A hits prop asks did he get on base with a hit. A total bases prop asks how far did he get. Those are different questions and they reward different hitters.
A contact hitter batting .300 with fifteen doubles a year puts up hits without putting up bases. A hitter batting .230 with thirty home runs does the reverse: he strikes out twice, then hits one 430 feet and puts four on the board in a single swing. Which of them is the better bet depends on the two lines and the two prices, not on the profile alone.
This is why a total bases line of 1.5 is not “roughly two hits”. It is one double, or two singles, or one swing that ends the question entirely.
What to check before you take one
Extra-base ability, not batting average. Isolated power, which is slugging percentage minus batting average, is the cleanest one-number version of “when he hits it, does it go anywhere”.
Whether the park helps. A ball hit into the gap in a big outfield is a double or a triple. The same ball in a small park is caught or is a home run. Both change the total bases number, in opposite directions.
How many chances he gets. A hitter batting leadoff gets one more plate appearance than the guy batting seventh roughly every other game. On a market where a single swing can be worth four, an extra chance matters more than it does almost anywhere else on the board.
Who is pitching, and from which side. Ground-ball pitchers suppress extra bases, because ground balls rarely go for extra-base hits.
Every one of those inputs sits beside the line on the board, which is the fastest way to check them together.
Where to see today’s numbers
Every total bases line on the Lab board sits next to the form and the price it is available at, and today’s MLB player props carries the ones we selected with the book beside them.
If you want to know whether the price on that line is any good before you take it, overs vs unders on player props is the place to start.
A note on the examples
Both games come from the Lab forward test, which records leans off the board and settles them from the official game feed. They are reads we published rather than bets this desk placed, and they are here to show a settlement rule rather than to make a claim about the market.
Quick answers
Do walks count as total bases?
No. A walk puts a runner on first but it is not a hit, so it counts zero total bases. This is the most common misread in the market.
Do stolen bases count as total bases?
No. Total bases counts the bases the hit was worth, not the bases the runner reaches. A single followed by a stolen second is still one total base.
How many total bases is a home run?
Four. It is the maximum a single plate appearance can produce, which is why home run hitters carry higher total bases lines than contact hitters with better averages.
Does a sacrifice fly count as a total base?
No. A sacrifice fly is not a hit, so it returns zero total bases even though it drove in a run.
