The Oakland Athletics' 1981 season saw the A's finish with an overall record of 64 wins and 45 losses. They finished the season with the best record in the American League (and second best in all of baseball). Due to the infamous 1981 players strike, the league resorted to a split-season format; this new format saw the winners of both halves of the season playing in the first divisional playoff in MLB history. The A's qualified by posting the AL West's best record in the first half of the season. While they swept the Kansas City Royals in the AL West playoff, they were themselves swept by the New York Yankees in the 1981 American League Championship Series.
