The Royals went up 2–0 in the fourth off of Danny Cox when Willie Wilson hit a leadoff single that was followed by back-to-back RBI doubles by George Brett and Frank White. However Charlie Leibrandt continued a history of tough luck in the postseason. The previous year, he had lost Game 3 of the 1984 ALCS, 1–0, to the Detroit Tigers when he pitched a three-hit complete game. He lost Game 4 in the 1985 ALCS in the ninth inning. And clinging to a two-run lead in the ninth, manager Dick Howser opted to not send in his relief ace Dan Quisenberry to close out the game. Leibrandt allowed a leadoff double to Willie McGee, then was only one out from tying the series at one apiece when he allowed an RBI single to Jack Clark. After a double and walk loaded the bases, Terry Pendleton cleared them with a double and gave the Cardinals a 4–2 lead. Quisenberry came in and after he walked Darrell Porter he got out of the inning. Jeff Lahti earned a save with a scoreless bottom of the inning. The Cardinals' four run ninth would be the only inning in the series in which they scored more than one run.
