Scipio Ronald Spinks (born July 12, 1947) is an American former right handed pitcher in Major League Baseball who played from 1969 through 1973 for the Houston Astros and St. Louis Cardinals.

Born in Chicago, Illinois, Spinks was a promising prospect until injuries prematurely ended his career.

The hard-throwing Spinks had control problems but also struck out an average of one batter per inning in the American Association.

While scoring from first on a double, he ran into Cincinnati Reds catcher Johnny Bench in a collision at home plate.

After his playing career ended, Spinks became a scout and a pitching coach in the San Diego Padres and Houston Astros organizations.
