When It Was a Game 3 focuses on the 1960s, a time of change for all of America. Through sharp, incredibly clear color footage of players and fans, the film shows how Major League Baseball slowly but surely evolved from pure sport to moneymaking entertainment. Covering the mighty Yankees, the western expansion of both leagues, the increasing inclusion of black players, and the rise of free agency and increased salaries, the film shows the growth of baseball from adolescence to adulthood.
