Bjornlund won his second freestyle World Cup race in two days. Bjornlund was slower than Wilson, of Butte, Mont., but received more points for his turns, finishing with a total score of 24.96 to nip the American's 24.95.
A top-three World Cup finish is one of the surest ways to make the U.S. Olympic team. So far, Wilson and Kearney have two and Roberts has one.
Roberts had his best World Cup result in two seasons. He is on a mission to make the Olympic team after narrowly missing a spot in 2006.
"Right now, being on the podium has taken the pressure off before Christmas and worrying about the Olympic spots," Roberts said. "It gives me confidence to know that if I ski the way I can and I'm capable of, I can hit the podium every week."
