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.
It was the first World Series between eastern and western Negro leagues champions since 1927, resuming after a 14-year lapse since the collapse of the Eastern Colored League had ended the previous post-season meetings. The series featured seven members of the Baseball Hall of Fame, three from the Monarchs (Satchel Paige, Hilton Smith, and Willard Brown) and four from the Grays (Josh Gibson, Jud Wilson, Ray Brown, and Buck Leonard). One additional Hall of Famer, Leon Day, played in one of the games that was not counted, Monarchs legend Bullet Rogan umpired in that same game.
The Monarchs and Grays had met during the regular season in two exhibition games, in which the Grays had twice defeated Monarch ace Satchel Paige in extra innings. Some of the pre-Series publicity had concentrated on whether Paige would be seeking revenge for his losses or whether the Grays truly held a "jinx" over him and would continue to dominate him. Paige pitched in all four official games and earned one victory and one save.
This was the Grays' first appearance ever in the Negro World Series, though this was their third consecutive NNL pennant, and fifth in six seasons. They would appear in the next three CWS, winning in 1943 and '44. It was the third appearance by the Monarchs (going back to 1924) in the CWS, their second championship, and their fifth NAL pennant in six seasons. They would appear one more time, losing to the Newark Eagles in 1946.
