Chapter 6: Quirky Trivia

Baseball has a long record of odd moments. In August 1951 Bill Veeck sent Eddie Gaedel, a man he had signed a few days earlier, to bat; Gaedel remains the shortest player in big-league history, Veeck wanted a walk rather than a swing, and the pitcher could not find his tiny strike zone. Will Harridge called it a mockery of the game, and Gaedel's jersey is kept at the Hall of Fame.
Promotions sometimes went badly wrong. On Disco Demolition Night in Chicago, 12 July 1979, a crate full of vinyl was detonated between the games of a doubleheader, a riot followed, and the Tigers won the forfeit because the field had been badly torn up. Ten Cent Beer Night in Cleveland, 4 June 1974, drew around 25,000 fans to the old Municipal Stadium and ended with the umpire calling the game off. Sports Illustrated's 1 April 1985 story of Sidd Finch, a 168-mph pitcher, was a hoax by George Plimpton, and the clue was in the date. Moe Berg, a reliable backup catcher, was sent to judge how close Germany was to an atomic bomb.
The facts below cover Gaedel, the two promotions, the Finch hoax, Berg, superstitions, strange injuries, animals at the ballpark, players who took all nine positions in one game and strange plays.
