The victory was the 25-year-old Swedish Olympic gold medalist's seventh overall in the World Cup this season.
Just like on Friday, Alexandra Edebo won the women's B-final, the so-called small final, and finished fifth overall.
David Mobärg, who together with Näslund arranged a Swedish double victory yesterday, did not make it to a new A-final on Saturday.
Instead, he and his brother Erik had to drive the B-final where they finished second to last and last and shared eighth place overall.
Next week, the ski cross's world cup circus continues to Sweden with two competitions in Idre before the Olympics in February.
