The Baseball Boxscore is a summary of a game's statistical events in a small, neat package, originally designed for Newspaper sports sections. The boxscore can tell you everything you need to know about a game including the score, batting and pitching stats as well as game information such attendance and time of game. Though similar in most cases, there are variations between publishers including in the present day where different sites will publish the boxscores in slightly different formats though the core of the boxscore will always stay the same.
The Baseball Cube publishes boxscores in a similar format to most other with our little twists to try to pile the most game information into one boxscore as possible. In addition to the boxscore page, there is also a play by play which provides an auto-generated descriptive view of the game. In all cases of boxscores and for all pages, the data is sourced from Retrosheet
who do an incredible job of documenting baseball history at a granular level.
The range of years available on the site is 1957-present day. Boxscores are accumulated during the current season, each morning but are not from Retrosheet and are instead compiled programmatically by TBC and may be subject to small discrepancies, especially when resulting from plays that are less common.
