Steven Rance Mulliniks (born January 15, 1956) is an American former Major League Baseball player.

Drafted as a shortstop, Mulliniks made his major league debut in 1977 for the California Angels, batting .269 in 78 games.

He had been traded along with Willie Aikens from the Angels to the Royals for Al Cowens and Todd Cruz at the Winter Meetings in Toronto on December 6, 1979,[1] with Craig Eaton being sent to California to complete the transaction four months later on April 1, 1980.

He batted over .300 three times (1984, 1987 and 1988) and demonstrated great patience at the plate, regularly posting on-base percentages near .400.

Mulliniks has been a colour commentator for Blue Jays coverage on Rogers Sportsnet, and alongside Jim Hughson and Jesse Barfield on CBC Sports in 2007 and 2008.
