Negro Leagues Data Is Now Available on FanGraphs!

All calculations for these leagues, including WAR, are treated as if these leagues were part of our original major league historical data, with the following exceptions:

– There are some years/leagues for which pitcher home run allowed data is not available. For these years, we are only calculating RA9-WAR and have substituted that for our FIP-based WAR in the “WAR” column. Should home run allowed data become available in the future for these years/leagues, we will adjust accordingly.

– The park factors for these leagues are currently calculated as neutral. We may revise this in the future.
