The 1942 Negro World Series was a best-of-seven match-up between the Negro American League champion Kansas City Monarchs and the Negro National League champion Washington-Homestead Grays. In a six-game series, the Monarchs swept the Grays four games to none, with two additional games not counted in the standings. The Monarchs actually won the 1942 series 5-1, but a second game played in Yankee Stadium on September 13 (a seven-inning victory by the Monarchs) was not counted by prior agreement, and the only game played in Kansas City was thrown out on appeal when the Grays used unauthorized players from other NNL teams.
