1989 - Prior to the start of Game Three of the World Series at Candlestick Park, an earthquake measuring 7.1 on the Richter scale devastated large parts of the Bay Area. The tragedy, the first of its kind to strike the World Series, forced postponement of the third game and caused Commissioner Fay Vincent to consider a change of venue for the rest of the Series. When the Series anticlimactically resumed 12 days later at San Francisco, the A's completed a sweep by winning back-to-back slugfests. Oakland beat Toronto 4-3 to win the ALCS 4-1 and advance to the World Series for the 2nd straight year.
