The United States had won just one alpine skiing medal coming into Sunday's event, but the Americans began making up for that with a second-place finish by Andrew Weibrecht and a tie for third by Bode Miller -- who at age 36 became the oldest alpine skiing medalist in Olympic history.
Miller was credited with the identical time as that of Jan Hudec of Canada and for the first time at the Olympics four medals were awarded in the same alpine race.
All the previous four ties in Olympic alpine history had been for either the silver or gold. The first gold medal tie took place earlier in these Games between Tina Maze of Slovenia and Dominique Gisin of Switzerland in the downhill.
Jansrud won his second medal of the Sochi Olympics, having wound up third in the downhill. He is 10th in the overall standings on the World Cup circuit this season and eighth in super-G.
He traveled the course in 1:18.14 to defeat Weibrecht by three-tenths of a second. Weibrecht won the bronze medal in this race four years ago in Vancouver, but has finished no better than 20th in a World Cup super-G during the current campaign.
Miller now has six Olympic medals to his credit. He broke the Olympic alpine record of Norway's Kjetil Aamodt for oldest medal winner. Aamodt was 34 when he won the last of his eight medals in 2006.
Miller finished only eighth in the downhill a week ago after turning in the fastest training on two occasions. He wound up 12th in the combined, a race he had won at the previous Olympics.
The warm weather that has prevailed during the Olympics caused the organizers to move the start time forward by an hour Sunday. It was 33 degrees at the starting gate and 41 degrees at the finish.
Eleven of the 62 competitors did not make it to the bottom of the course, including Christof Innerhoffer of Italy. He had won the bronze in the combined and a silver in the downhill at these Olympics.
