One Nation Under Baseball highlights the intersection between American society and America's pastime during the 1960s, when the hallmarks of the sport-fairness, competition, and mythology-came under scrutiny. John Florio and Ouisie Shapiro examine the events of the era that reshaped the game: the Koufax and Drysdale million-dollar holdout, the encroachment of television on newspaper coverage, the changing perception of ballplayers from mythic figures to overgrown boys, the arrival of the everyman Mets and their free-spirited fans, and the lawsuit brought against team owners by Curt Flood.

One Nation Under Baseball brings to life the seminal figures of the era-including Bob Gibson, Marvin Miller, Tom Seaver, and Dick Young-richly portraying their roles during a decade of flux and uncertainty.
