|1981 World Series|
Due to a strike-shortened season, each team had to win two playoff series to reach the World Series. Oakland had swept the Kansas City Royals three games to none and the Yankees had beaten the Milwaukee Brewers three games to two in the 1981 American League Division Series. The Yankees swept the Athletics three games to none in the Series and moved on to the 1981 World Series, where they would lose to the Los Angeles Dodgers.

Game summaries 
Game 1 
|WP: Tommy John (1–0) LP: Mike Norris (0–1) Sv: Goose Gossage (1)|
In Billy Martin's return to Yankee Stadium (for the first time since the Yankees fired him in 1979), the Yankees drew first blood in front of their old skipper. Graig Nettles' three-run bases-loaded double in the first inning was all the run support that Tommy John needed.
John gave way to Ron Davis after six innings. Davis had an easy seventh, but the A's mounted a threat in the eighth where Martin tried some of his "Billyball" tactics. Dwayne Murphy walked with one out. On a 1–0 count, the next batter, Cliff Johnson, stepped out of the batter's box to replace his bat and took an unusually long time, as ordered by Martin. This rattled Davis to the point where he complained loudly to the home plate umpire and threw three more balls, walking Johnson. Yankee manager Bob Lemon removed Davis and brought in closer Goose Gossage earlier than expected to face Tony Armas. Armas was the tying run at that point and was also the A's leading home run and RBI man. Gossage retired Armas and Wayne Gross to end the inning and closed out the win the rest of the way.
Game 2 
|WP: George Frazier (1–0) LP: Steve McCatty (0–1)
NYY: Lou Piniella (1), Graig Nettles (1)
With a 3–1 lead after 3 1⁄2 innings and American League ERA leader Steve McCatty cruising, the A's seemed headed for a 1–1 tie going back home to Oakland. It could have been worse, but Dave Winfield made a leaping catch in the second to rob Tony Armas of a homer.
But, Graig Nettles led off the bottom of the fourth with a single and Rick Cerone was hit by a McCatty pitch. After Willie Randolph singled in Nettles, Jerry Mumphrey walked. Dave Beard came on in relief and proceeded to give up an RBI single to Larry Milbourne, a two-run double to Winfield, and a three-run homer to Lou Piniella. Beard gave up two more hits and loaded the bases after that, but Cerone flied out to end the disastrous inning. The Yankees now led 8–3.
The Yankees added five more runs, three coming on a Nettles homer in the seventh, to complete the rout.
Game 3 
|WP: Dave Righetti (1–0) LP: Matt Keough (0–1)
NYY: Willie Randolph (1)
Prior to the game, Bob Lemon inexplicably dropped Willie Randolph from the leadoff spot in the batting order to ninth. Randolph kept any ill feelings to himself and broke a scoreless pitching duel between Dave Righetti and Matt Keough with a solo homer in the sixth. That run would be all Righetti would need through six innings. Series MVP Graig Nettles plated three more runs in the ninth with a bases-loaded double resulting when A's center fielder Rick Bosetti turned the wrong way on his fly ball.
