In 1989 , Craig 's Giants won their first National League pennant since 1962 . Led by sluggers Kevin Mitchell and Will Clark and starting pitcher Rick Reuschel , they won 92 regular-season games ( their most since ) and took the NL West title by three games over the Padres . Then they defeated the Chicago Cubs in five games in the 1989 National League Championship Series . But Craig 's Giants were swept in four games by the Oakland Athletics in the World Series . That Series , the first ever between San Francisco Bay Area teams , was marred by the 1989 Loma Prieta earthquake , which struck October 17 , minutes before Game 3 , scheduled for Candlestick Park . The quake killed 63 people and caused over 3,750 casualties . It delayed the World Series for ten days
