The Blitzboks won 35-5, after leading 14-0 at the break.
After a slow start in which they had to fend off a gallant Spanish side on their own tryline, the South Africans clicked into gear and eventually ran in five tries, with speedster Rosko Specman bagging a brace.
Goal-kickers - Justin Geduld and Selvyn Davids - also impressed by slotting all five conversions.
