Harris's narrator Henry "Author" Wiggen, a star pitcher, tells the story of a baseball season with the New York Mammoths, a fictional team based on the New York Giants, as noted in the author's book Diamond: The Baseball Writings of Mark Harris. In the novel, Wiggen befriends a slow-talking catcher from Georgia named Bruce Pearson who is more ridiculed than respected by his teammates. When Pearson learns he is terminally ill with Hodgkin’s disease and is to be sent to the minor leagues, Wiggen rallies his teammates to keep the catcher among them and inspires Pearson to become a better player before his time runs out. The novel was also chosen as one of the top 100 sports books of all time by Sports Illustrated,and the 1973 film adaption is featured on numerous other lists of best baseball movies.
