The New York Black Yankees played from 1931* through 1948 when they, along with the rest of the Negro National League, disbanded after the 1948 season. Although the disbandment of the NNL may have been a source of consternation for many fans, the end of the New York Black Yankees may have been considered an act of mercy. (*The team played as The Harlem Stars in 1931.)
Over their 18 seasons, the team posted a .347 winning percentage overall, which for some modern perspective translates to 56 wins over 162 games. Over their last six seasons, they (almost unimaginably) lost more than three-quarters of their games, finishing in last or second to last place in the NNL each of those six seasons.
