A Note on Dialects

Scorekeeping is a language with regional accents. Some books write an unassisted groundout to first as 3U, others just 3. Some scorekeepers circle RBIs, others underline them. None of it is wrong. What matters is consistency inside one book, so that anyone reading it, including you in five years, can follow the game.

For how these marks fit together in a real game, read how to use a baseball scorebook, or the deeper scoring symbols guide with examples.
