Tied After 8 Innings in MLB: Who Wins, and How Often Is It Extras?

A tie after eight innings feels like a coin flip with a home crowd attached. I wanted to know how true that is: how often it ends in the 9th, how often it drags into extras, and who wins each branch. Public records for 2000-2025 give 61,233 regular-season games of nine or more innings, and 5,985 of them were level after eight.

The headline answer is that 55.7% reached extra innings and the home team won 51.9%, a fair price of −108. That is a modest edge. The real story is the top of the 9th, where one half-inning swings the home side from favourite to long shot. If you want the wider context for how I approach these spots, my free baseball picks page sets out my process.

Branch AA late tie pushes games into extras far more often

This chart starts from a level score at different points of the game. Tied after five, only 17.7% of games reached extras. That rises to 23.8% after six, 34.8% after seven and then jumps to 55.7% after eight.

The jump in the final step matters. With only two half-innings left in regulation, there is very little time for either bullpen to give something up.

For anyone pricing extra-innings props in play, the lesson is simple. A tie after seven still usually ends in nine, but a tie after eight more often than not does not.

Branch BThe four branches split almost evenly between home and road

Here every game tied after eight falls into one of four outcomes. Across all seasons the road team won in the 9th 21.0% of the time, the home team walked off in the 9th 23.3%, the home team won in extras 28.6% and the road team won in extras 27.1%.

The home side holds a small edge in both regulation and extras, which is where the 51.9% comes from. Last at-bat helps, but less than many bettors assume.

The split moves between eras. In 2000-19 (4,698 games) road teams won 26.4% in extras; in 2020-25 (1,287 games) that rose to 29.9%, while home extras wins dipped to 27.7%. Since 2020 every extra inning starts with a runner on second, which makes extras shorter and higher-scoring and appears to blunt the home team's last-bat advantage. The recent sample is small, so I read that shift as a lean, not a law, and bullpen quality is not modelled anywhere here.

Branch CThe top of the 9th flips the home edge either way

This is the table I keep coming back to. The road team scored in the top of the 9th in 24.7% of tied games (1,479 games), and the home team then won only 11.0% of those. One run in that half-inning turns a near coin flip into a heavy road favourite.

When the road team was held scoreless (4,506 games), the home team walked off in the 9th 28.6% of the time and the game went to extras 71.4%. Overall the home team won 65.3% from that spot, a fair price of −188.

The recent era is softer for the home side: after a scoreless top of the 9th they won 66.1% in 2000-19 and 62.2% in 2020-25. Bear in mind that once any of these in-play states is known, the pre-game line can no longer be bet; these are prices for the live market only.

Branch DLow-scoring ties lean slightly more towards the home team

Not every tie looks the same. Low ties after eight (0-0 to 2-2, 2,547 games) reached extras 56.0% of the time, while ties of 5-5 or higher (1,395 games) did so 52.8%.

The home win rate also drifts down as the score climbs: 53.3% for low ties, 51.2% for 3-3 or 4-4 and 50.2% at 5-5 or higher.

My reading is that high-scoring games usually mean tired pitching staffs on both sides, which levels the field. In a low tie the home side's last at-bat counts for a little more, though the differences are small enough that I treat them as a nudge.
