Please keep in mind that the Batter vs. Pitcher app is based on the play-by-play event data from Retrosheet, and as such is subject to limitations within that data.
The main limitations of the data are:
- The current season of data is not included
- The game data starts with the 1950 season
- There are games missing in seasons up to and including the 1973 season
Please visit this page for lists of games that are missing from the Retrosheet data:
As soon as older data becomes available, or after a baseball season is over and the event files are updated, there will be an update to the Batter vs. Pitcher app with the newest data.
