In a decade dominated by the New York Yankees, Babe Ruth became the nation's "heirloom." Inning four of Ken Burns' sweeping nine-part documentary series focuses on the years 1920-1930, when baseball's black mark left by the Black Sox scandal of 1919 was erased by the legend of Babe Ruth. His impact on the game far overshadowed the previous achievements of the beloved Ty Cobb. This episode also highlights other great players of the decade such as Rogers Hornsby and Walter Johnson, the organization by Rube Foster of the Negro Leagues, and the barnstorming of the country by the House of David. ~ Kathryn Tamms, Rovi
