The 1988 American League Championship Series was a best-of-seven series that pitted the East Division champion Boston Red Sox against the West Division champion Oakland Athletics. It was the second meeting between the two in ALCS play. The Athletics swept the Series four games to none and would go on to lose to the Los Angeles Dodgers in the 1988 World Series.
The Oakland Athletics' 1988 season involved the A's winning their first American League West title since 1981, with a record of 104 wins and 58 losses. In 1988, the elephant was restored as the symbol of the Athletics and currently adorns the left sleeve of home and road uniforms. The elephant was retired as team mascot in 1963 by then-owner Charles O. Finley in favor of a Missouri mule. The A's defeated the Boston Red Sox in the ALCS, but lost the World Series to the Los Angeles Dodgers in five games, including a dramatic, classic walk-off home run by the Dodgers' Kirk Gibson in game one.
1988 was the first of 3 straight years the A's would represent the AL in the World Series
