The Line Score
Runs by inning across the top, then runs, hits and errors, which is the shortest honest summary of a game.
What it actually is. The line score shows each team's runs inning by inning, followed by three totals: runs, hits and errors. A dash means the home team did not bat in that half inning, which happens in the ninth when it is already ahead. An x in the last column means the same thing.
What somebody who knows the game gets out of it. The line score answers a question the box score does not: whether the runs came in a rush or a trickle. Six runs in one inning and six runs spread across six innings look identical in a box score and describe completely different games, and the clustered version is much more often the product of one pitcher losing the strike zone than of good hitting. Reading a line score first is the fastest way to know what kind of game you missed.
The numbers worth knowing. Nine or more columns, plus R, H and E. A big inning of four or more runs happens in roughly a third of games.
What people get wrong about it. A team can out hit the other and lose comfortably, and it happens constantly, because hits are not runs and the line score is showing you the difference between them. The R column is the only one that counts.
At Little League and travel ball. Youth line scores frequently show run limits per inning, usually five, which caps the big inning and changes the shape of a game entirely. A youth team down six after two innings is in a different position from a professional one, because the comeback has to come in installments.
