Book excerpt: Outsider Baseball is the story of a forgotten world, where independent professional ball clubs zig-zagged across America, plying their trade in big cities and small villages alike. Included among the former and future major leaguers were mercenaries, scalawags, and outcasts. This is where Babe Ruth, Rube Waddell, and John McGraw crossed bats with the Cuban Stars, Tokyo Giants, Brooklyn Bushwicks, dozens of famous Negro league teams, and novelty acts such as the House of David and Bloomer Girls. Legends emerged in this alternate baseball universe and author Scott Simkus sets out to share their stories and use a critical lens to separate fact from fiction. Written in a gritty prose style, Outsider Baseball combines meticulous research with modern analytics, opening the door to an unforgettable funhouse of baseball history. Scott Simkus is the founder and editor of the Outsider Baseball Bulletin. He is the winner of a research award from the Society of American Baseball Research for his work on the Negro League Database.
