The A's made it to the World Series the next two years, winning the 1989 "Loma Prieta earthquake" series 4-0 vs. the San Francisco Giants and being swept by the Cincinnati Reds 4–0 in 1990. The A's haven't appeared in the World Series since. The closest the A's have gotten to the World Series since that time was in 1992, when they lost to the Toronto Blue Jays in the American League Championship Series in six games and 2006, when they lost to the Detroit Tigers in the ALCS in a four-game sweep.
