In his historical narrative, "Roger Maris and a Cast of Hundreds", Gregory Rom describes the events in Major League Baseball (MLB) in the years 1957 through 1968. This was a simpler time when there were fewer teams playing in MLB. The American and National League pennant pursuits seemed to unfold with more apparent drama over the course of the summer. In his unique approach, Rom reports on individual games of the leading teams in each pennant race. In those years, the League pennant pursuits led directly to the World Series. Rom summarizes the key games and player performances of each World Series of the twelve-year period. In the midst of his game-by-game narrative, Rom skillfully interweaves background information to provide a historical baseball context about the most successful players of the era, which he calls interludes, and even references important historical events in the world, which took place on the same days when some of the important games were played.
