"The National Pastime" leads off with the baseball season of 1941, one of the most exciting of all time. Joe DiMaggio hit in 56 straight games, the longest hitting streak before or since. Ted Williams became the last man to hit .400. And the Brooklyn Dodgers won their first pennant in 20 years. Then the war intervenes and baseball's best players become soldiers. On their return, the game -- and the entire country -- are changed: Branch Rickey integrates baseball on April 5, 1947, when Jackie Robinson of the Brooklyn Dodgers takes the field. Baseball finally becomes in fact what it had always claimed to be: America's national pastime. John Chancellor narrates.
