Reaching the post-season for the first time in his career, Lemon went hitless in thirteen at-bats in the Tigers' three-game sweep of the Kansas City Royals in the 1984 American League Championship Series. He improved in the World Series, batting .294 with a run scored and a run batted in. He also had "a Willie Mays–style back-to-the-plate catch" on a Terry Kennedy drive to preserve the Tigers' lead in the seventh inning of Game 3.
