About The Project
baseball.computer is a free, open-source database of historical baseball statistics and play-by-play data. It builds on top of historical data sources and new database technology to provide a novel combination of detail, flexibility, and power for baseball analysis. It is currently in a preview release, and it will have bugs in data and functionality.
