In 1984, the Associated Press stated that Stein was one of the American League's best pinch hitters. Early into the season, he injured his wrist, which caused him to miss some playing time. In mid-June, the Rangers activated him from the disabled list. On the season, Stein batted .279 with three runs scored, 12 hits, one double and three RBIs in 27 games played. Stein played 11 games at second base, three games at first base, and three games at third base. He also spent four games as the Rangers designated hitter.
