Halfway through the four-round event, Mazdzer was in fourth place, with a total time of 1:35.517 - just one one-thousandth of a second behind Roman Repilov, Olympic Athlete from Russian Federation, but it would have been enough to keep him off the medal stand.
Mazdzer broke the course record Loch had set moments earlier to vault into second place, putting together a flawless run. His podium finish ends a drought that extends to the sport's Olympic debut back in 1964. Instead of winning his third gold medal in a row in men's singles luge, and matching fellow German Georg Hackl as the only man to win three straight golds, Loch faltered on the final run of the night, falling to fifth place as Austria's David Gleirscher pulled off a thrilling upset over one of luge's all-time greats.
Mazdzer won silver in the men's singles luge - becoming the first American to medal in the event. The U.S. women's team has won either a gold or silver medal in the Games since women's ice hockey was introduced in 1998 and has faced Canada in four of the five gold-medal contests.
The highest the USA men had ever placed in the Olympics was fourth in 2002 (Adam Heidt) and 2006 (Tony Benshoof).

But she chose to sit out the giant slalom, saying that her knee "is just not really in a place to do that". The gold she returned in Vancouver eight years ago was the first by an American woman in the downhill.
Mazdzer finished 13th in two previous Winter Games, so this was quite a step up.
Since Keshavan finished outside the top 20 after three runs, he did not get to compete in the fourth and final run, which decided the medals.
The medal is the United States's sixth all time in luge and second in singles. Germany has dominated the luge event historically, and it looks like they're positioned well to walk away with the gold medal once again.
"The men's medal and then the gold medal, and then we'll be a happy organization", Caligiore said.
