Hugh Stuart Fullerton III was an American sportswriter in the first half of the 20th century. He was one of the founders of the Baseball Writers' Association of America. He is best remembered for his role in uncovering the 1919 "Black Sox" Scandal. Studs Terkel played Fullerton in the 1988 film Eight Men Out.

The 1919 World Series was the championship series in Major League Baseball (MLB) for the 1919 season. The 16th edition of the World Series, it matched the American League champion Chicago White Sox against the National League champion Cincinnati Reds. Although most World Series have been of the best-of-seven format, the 1919 World Series was a best-of-nine series. MLB decided to try the best-of-nine format partly to increase popularity of the sport and partly to generate more revenue.
