The 1989 World Series , sometimes called the " Bay Bridge Series " or the " BART Series " ( after the connecting transit line ) , featured the Oakland Athletics and the San Francisco Giants , teams that play just across San Francisco Bay from each other . The series is most remembered for the major earthquake that struck the San Francisco Bay Area just before game 3 was scheduled to begin . The quake caused significant damage to both communities and severed the Bay Bridge that connects them , forcing the postponement of the series . Play resumed ten days later , and the A 's swept the Giants in four games . ( The earthquake disruption of the Series almost completely overshadowed the fact that the 1989 Series represented a resumption after many decades of the October rivalry between the Giants and the A 's dating back to the early years of the 20th Century , when the then-New York Giants had defeated the then-Philadelphia Athletics in 1905 , and had lost to them in 1911 and again in 1913 . ) The Giants are the only team to have played in cross-town World Series in two cities , having faced the Yankees six times while located in New York , and the Athletics once while based in San Francisco
