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.

Missing Home Run Allowed Years
League Abbreviation Years No Home Run Allowed Data
Negro National League I NNL 1920-1931 1925, 1927, 1929, 1930, 1932
Eastern Colored League ECL 1923-1928 1924-1925
American Negro League ANL 1929 —
East-West League EWL 1932 —
Negro Southern League NSL 1932 1932
Negro National League II NN2 1933-1948 1939-1942
Negro American League NAL 1937-1948 1939-1942

– The Fielding component for all Negro Leagues data uses Michael Humphrey’s Defensive Regression Analysis (DRA) calculation as opposed to Sean Smith’s Total Zone (TZ).

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

Is there anywhere else historical DRA data is available online? Baseball Gauge used to have it until bbref bought them out, but br hasn't incorporated DRA into their reported metrics unless they've done it very recently.

If I recall reading part of his book, his numbers tend to vary much more into the positive and negative ends than TZ. But I dont think I ever read about his methodology per se.
