The TBC Newsletter
will keep you periodically up-to-date on what is happening at The Baseball Cube.
Umpire data is derived from the Retrosheet Boxscore data that we have included on the site. Each Umpire has a Retrosheet Player ID and we have created a TBC ID for the umpire, despite the fact he will have no playing statistics. We have compiled some basic bio data and using the Retrosheet data, have compiled some basic analytics for the umpires for metrics that might have impact on the games for which they umpire at home plate.
The range of years for umpire data is restricted to the range of years of Retrosheet data. The Umpire data for the new season is updated, generally as low priority, at the conclusion of the latest MLB season.
