Extra innings markets
| Market | You bet on | Watch for |
|---|---|---|
| Extra innings | Yes or No | Low totals |
| Tie after 9 | Same as Yes | Wording |
| Run in the 10th | Yes or No | Free runner |
| Winner in extras | After a tie | Bullpens |
Names vary by book.
The free runner rule
In the regular season each team starts every extra inning with a runner on second base. The rule began in 2020 and became permanent in 2023.
It makes scoring in the 10th much more likely, so most extra-inning games end in the 10th or 11th.
Rough tie chances
| Game type | Chance of extras |
|---|---|
| Total 7, even teams | Higher |
| Total 8.5, average | About 9% |

Floor rules
Extra innings terms
Know before you sit
- Extras
- Innings after the ninth.
- Tie after 9
- The score is level after nine full innings.
- Bullpen
- A team relief pitchers.
- Run line

Bullpens and closers
Strong bullpens keep late innings low scoring, which can lead to more ties after nine.
Teams that used many relievers the day before may struggle in extras.
Check bullpen usage over the last few days before you bet.
Common mistakes
- Ignoring the total
- Low totals tie more.
- Missing the rule
- Free runner speeds games.
- Mixing markets
- 9 innings or full game.
- Overbetting long shots
- Most games end in 9.
Ballparks and weather
Pitcher-friendly parks and cold weather lower scoring, which helps the Yes side.
Wind blowing out at hitter parks raises scoring and lowers the chance of a tie.
Totals already price most of this, so compare the total with the extras price.
Reading the prop line
The Yes side is usually a long price, since most games end in nine innings. Lines move with the total and with how even the two teams are.
A low total between two good pitching staffs often has the shortest Yes price on the slate. A high total with a big favorite usually has one of the longest.
Weather delays and suspended games can change settlement, so keep the house rules in mind.
