The Americans flew the flag high at one of the marquee events at the Winter Games yesterday.
Paula Moltzan and David Chodounsky won the slalom gold medals in demanding conditions at the Coronet Peak Race Arena.
Competition was extremely tight in the fight for the men's title, with just 0.08sec separating Chodounsky (29) and second-placed Akira Sasaki (31), of Japan, followed by Adam Zampa (22), of Slovakia, who won the men's giant slalom on Monday.
Chodounsky had the fastest first run in 44.19sec but was pipped by Sasaki in the second, who blitzed the field to finish in an unbeatable 40.15sec.
Chodounsky clocked a combined time of 1min 25.24sec to Akira's 1min 25.32sec and Zampa's 1min 25.61sec in a spectacular finish between the top seeds.
Chodounsky, ranked 25th in the world, was upbeat about his win after two recent wins in Australia.
''It's proving to be a great summer. I am on a roll,'' he said.
''The first run got quite rough but the second held up well and although I made a little mistake I am pleased with the result.''
Akira, ranked 35th in the world, was also pleased with his placing.
''My coach set the second course, which was helpful for me. The Winter Games has been very important for me because I want to qualify for Sochi.''
Zampa is ranked 37th in the world and, with slalom as his favourite discipline, would have preferred to be higher on the podium.
He was lying second after the first run but ''braked a bit much'' in the second run, which put him into third.
American Will Brandenburg, vying for a top three placing after finishing third in the first run, straddled a gate in the second run, putting him out of contention.
New Zealand representative Adam Barwood (21) was the first Kiwi, in 21st place, clocking 1min 29.05sec for a 33-point result which will lower his world ranking.
In the women's event, racing was just as tight.
Moltzan (19), who was second after the first run in 43.01sec, had a combined result of 1min 29.04sec.
Michelle Gisin (19), of Switzerland, had the fastest first run in 42.74sec but had to be content with second overall in 1min 29.17sec.
American Megan McJames (25) came from 13th place after the first run, recording the third-fastest second run of 45.37sec, to claim the bronze medal in 1min 29.90sec.
The fastest second run was clocked by 16th-placed Ricarda Haaser (20), of Austria, in 45.26sec (combined 1min 31.29sec), ahead of Ando Asa (17), of Japan, in 45.33sec. Asa was 10th overall in 1min 30.69sec.
Moltzan, ranked 144th in the world, is training in New Zealand as a member of the US Europa Cup team. She was overwhelmed by her win, her first at Australia New Zealand Cup level.
''The second run was very bumpy but I just kept going. This is a very exciting result in my career,'' Moltzan said.
First New Zealander was 17-year-old Eliza Grigg, who started in bib 61 and claimed 33rd place in 1min 41.93sec.
Ninety-seven men and 67 women, representing 17 countries, competed in the Audi Quattro-sponsored Winter Games slalom.
The Rocky Gully course was described by FIS Australia New Zealand Cup chairman David Howden as ''close to world cup level''.
