Book excerpt: Think you know how the game of baseball began? Think again. Forget Abner Doubleday and Cooperstown. Did baseball even have a father--or did it just evolve from other bat-and-ball games? John Thorn, baseball's preeminent historian, examines the creation story of the game and finds it all to be a gigantic lie. From its earliest days baseball was a vehicle for gambling, a proxy form of class warfare. Thorn traces the rise of the New York version of the game over other variations popular in Massachusetts and Philadelphia. He shows how the sport's increasing popularity in the early decades of the nineteenth century mirrored the migration of young men from farms and small towns to cities, especially New York. Full of heroes, scoundrels, and dupes, this book tells the story of nineteenth-century America, a land of opportunity and limitation, of glory and greed--all present in the wondrous alloy that is our nation and its pastime.--From publisher description.
