Smith became a father for the first time during the 1982 season with the birth of his son O.J., today known as Nikko, on April 28. Smith also developed a lasting friendship with teammate Willie McGee during the season, and Smith said he likes to think he "helped Willie get over some of the rough spots of adjusting to the major leagues". Smith later participated in the postseason for the first time when the Cardinals faced the Atlanta Braves in the best-of-five 1982 National League Championship Series (NLCS). Smith drove in the series' first run by hitting a sacrifice fly which scored McGee in Game 1, ultimately going five for nine in St. Louis' three-game series sweep.
