The Giants faced their cross-town rivals, the Oakland Athletics in the unforgettable "Bay Bridge Series", best remembered by the October 17, 1989 Loma Prieta earthquake which struck at 5:04 p.m., just before the scheduled Game 3 at Candlestick Park. After a ten-day delay, Oakland finished its sweep of the Giants, winning Games 3 and 4 at San Francisco. The Giants never led in any of the games.
