February 27, 2020 by Kevin Johnson · 1 Comment
We’ve added data from the 1942 Mexican League, a season of 84-88 games that finished with three teams within two games of first place. Union Laguna de Torreon posted the best record (48-40) thanks to Martin Dihigo, who proved why he’s one of the greatest players in baseball history. The 37-year-old Dihigo not only led […]
NORMALIZING NEGRO LEAGUE STATISTICS
February 13, 2020 by Kevin Johnson · 8 Comments
Most baseball fans are familiar with the concept of ‘normalizing’ statistics. For MLB statistics, the most basic adjustment is to normalize for park effects.

February 9, 2020 by Kevin Johnson · 2 Comments
Major League Equivalents (MLEs) are a series of calculations designed to take non-major league baseball performance and estimate what that performance’s results would look like statistically in the context of the Major Leagues.

Although the number of Negro Leaguers decreased from 67 to 58, in percentage terms they increased from around 33% to 40% of the total player population.
