Steven Rance Mulliniks (born January 15, 1956) is a former Major League Baseball player.
Originally drafted as a shortstop, Mulliniks made his major league debut in 1977 for the California Angels, batting .269 in 78 games.
He saw limited playing time over the following years with the California Angels until 1979 and with the Kansas City Royals in 1980 and 1981.
Mulliniks' luck changed when he was traded to the Toronto Blue Jays, just before the start of the 1982 season.
He was converted to third base and appeared in over 100 games each year through the 1989 season.
He batted over .300 three times (1984, 1987 and 1988) and demonstrated great patience at the plate, regularly posting on-base percentages near .400.
In 1984 he was named to Sports Illustrated's Dream Team as a utility infielder.
