First Inning, Our Game, looks at the origins of baseball in the 1840s and takes the story up to 1900. Burns refutes the myth that Abner Doubleday invented baseball in Cooperstown and traces its roots instead to the earliest days of the nation — there are records of a game called "Base" played at Valley Forge..
Second Inning, Something Like a War, takes viewers through 1910 and introduces some of the game's most celebrated and colorful characters, including Ty Cobb, Honus Wagner, Christy Mathewson and Walter Johnson., and includes the formation of the American League and its integration with the National League, culminating in the establishment of the World Series.
Third Inning, The Faith of Fifty Million People, examines the century's second decade, which was dominated by the Black Sox scandal. George Herman "Babe" Ruth makes his first major league appearance (as a member of the Boston Red Sox) and a wave of immigration helps fill the stands with new fans, eager to "become American" by learning America's game.
Fifth Inning, Shadow Ball, tells the story of the Negro Leagues in the 1930s. The title refers to a common pre-game feature in which the players staged a mock game with an imaginary ball. Though unintended, the pantomime was an apt metaphor for the exclusion of blacks from major league play at that time.
Sixth Inning, The National Pastime, covers the 1940s and includes Joe DiMaggio's celebrated hitting streak, the awe-inspiring performance of Ted Williams and what Burns calls "baseball's finest moment" — the debut of Jackie Robinson, who broke the color barrier as a member of the Brooklyn Dodgers in 1947.
Ninth Inning, Home, looks at baseball from the 1970s to the present, including the establishment of the free agent system, the rise in player salaries, the continued expansion, the dilution of talent, the ongoing battles between labor and management and the scandals. The documentary ends with an ironic claim that baseball, and indirectly the World Series, could never be stopped. The 1994 World Series, the series to be played the year the film was aired, was canceled due to a players' strike.
Ken Burns' follow-up to "Baseball" concludes with a look at dominating pitchers like Pedro Martinez, Japan's first MLB star, Ichiro Suzuki; the comfort provided by the game after the 9/11 attacks; revelations about performance-enhancing drugs; the Red Sox-Yankees rivalry; and Boston's World Series victory.
Bob Costas presents an inside look at the making of "Baseball," including interviews with Ken Burns and Lynn Novick, and insight into the impact "Baseball" had on America.
