It was the opening semifinal round on the American League side of the inaugural edition of the MLB postseason.
Frank Robinson's home run in the fourth put the Orioles up 1–0 off of Perry, but the Twins tied the game in the fifth inning when Tony Oliva hit a leadoff double off of Cuellar, went to third on Robinson's error and scored on Bob Allison's sacrifice fly.
Neither third baseman Harmon Killebrew nor catcher John Roseboro could make the play as Belanger sped across the plate with the winning run.
Both pitchers pitched shutout baseball into the 10th inning, until Curt Motton's pinch-hit single in the bottom of the 11th, scored Boog Powell from second base for the only run of the game.
Boswell was the losing pitcher with a line of 10+2⁄3 innings, with 7 hits allowed, 7 walks, and 4 strikeouts with the lone earned run of the game.
McNally pitched an eleven-inning complete game shutout (the longest in MLB postseason history), struck out 11 Twins batters and yielded only three hits, none after the fourth inning.
