Using never-before-seen documents and candid interviews with O'Malley's players, associates, and relatives, Pulitzer Prize-winning writer Michael D' Antonio finally reveals this complex sportsman and industry pioneer. Born into Tammany Hall connections, O'Malley used political contacts to grow wealthy during the Great Depression, and then maneuvered to take control of the formerly downtrodden Dodgers. After his defeat in a war of wills with the famed power broker Robert Moses, O'Malley uprooted the borough's team and transplanted them to Los Angeles. Once in Los Angeles, O'Malley overcame opponents of his stadium and helped define the city. Other owners came to regard him as their un-official commissioner as he worked behind the scenes to usher in the age of the players' union and free agency.
