About
Every big-league linescore since 1900, searchable inning by inning.
What this is
A linescore is the oldest summary in baseball: runs per inning, one row per team. This site holds every one of them since 1900 — more than 217,000 games — and lets you ask a question no box score archive answers directly: has this exact game ever happened before?
How search works
Enter an inning pattern and the archive returns exact matches first, each with a count of how many times that precise linescore has occurred. Close-but-not-exact games follow, ranked by how similar their scoring shape is — compared inning by inning, along with totals and when each team last scored.
Search is order-insensitive: it does not matter which team you enter first. You can also search a single team's row, or pull every game from a date to see which of that day's linescores were one-of-one. Roughly 71% of all games since 1900 have a linescore that has never occurred twice.
The data
Historical seasons come from Retrosheet game logs. Current-season games are added within about an hour of going final. The archive begins at the 1900 season and includes finished games only.
