<P> The 1989 World Series was the 86th edition of Major League Baseball 's championship series , and the conclusion of the 1989 Major League Baseball season . A best - of - seven playoff , it was played between the American League ( AL ) champion Oakland Athletics and the National League ( NL ) champion San Francisco Giants . The Series ran from October 14 through October 28 , with the Athletics sweeping the Giants in four games . It was the first World Series sweep since 1976 . The four game sweep by the Athletics at the time would mark only the third time in World Series history that a team never trailed in any game ( 1963 , 1966 , and 2004 World Series being the only other times this occurred ) , and the first in the playoff era ( post-1968 ) . </P>
