In the decisive 5th game of the 1972 American League Championship Series, the mutual dislike between Martin and Northrup may have affected Martin's judgment. In the 9th inning, the Tigers were trailing 2-1, and Norm Cash was on base. Northrup had one hit already off Vida Blue, but Martin used Mickey Stanley to pinch-hit for Northrup. Stanley hit into a fielder's choice, and the Tigers lost the ALCS. Northrup remained bitter about Martin's decision: "Who knows why Martin did what he did? I will say this: Billy Martin put most of us in a frame of mind where he took the fun out of the game."
