Merv Rettenmund singled and Paul Blair walked before Tommy Davis's RBI double put the Orioles up 1–0.
Andy Etchebarren was hit by a pitch to load the bases and Mark Belanger's RBI single made it 4–0 Orioles.
In the bottom half, the Orioles got back-to-back leadoff singles before Earl Williams's one-out RBI double cut Oakland's lead to 3–2.
Bert Campaneris, first man up in the 11th, snapped a 1–1 tie by hitting Cuellar's second pitch over the left-field fence for a home run.
The next inning, Bobby Grich hit a home run off Rollie Fingers and that, coupled with Grant Jackson's stout relief pitching, gave the game to the Orioles.
A surprisingly small crowd of 24,265 showed up for the final game and they saw Catfish Hunter pitch a five-hit shutout, winning 3–0.
The A's first run in the game come in the third inning when Ray Fosse reached first on an error by third baseman Brooks Robinson, moved to second on a sacrifice bunt, and scored on a single by Joe Rudi.
He was relieved by Palmer, who shut out Oakland the rest of the way, but the Orioles were helpless against Hunter's powerful pitching as the A's advanced to the World Series.
