Erin Hamlin is the only US luge athlete of any gender to medal in singles competition at the Olympics, having won bronze in 2014.
The 29-year-old athlete won the silver medal for his excellent placement in the event earlier in the day on Sunday (February 11) in PyeongChang, South Korea.
"For the Olympics, you just have to go for it", Mazdzer said Saturday after his first two trial runs.

Chris Mazdzer reacts following his track-record run during the luge men's singles at the Olympic Winter Games PyeongChnag 2018 on February 11, 2018 in PyeongChang, South Korea. But it was only with his second and third runs - which he finished second and first, respectively - that Mazdzer climbed the leader board. In both 2010 and 2014, he finished 13th.
He was in fifth place after Run 1 and then moved up a spot to fourth place in Run 2, but it was his performances in Runs 3 and 4 that sealed the deal.
NPR's Melissa Block reports he leaped from his sled after that final run, vaulting "into the stands to hug his family and grab an American flag".
But, Germany's Felix Loch who looked like he was on his way to his third consecutive Olympic gold, faltered on the final run and finished 5th. Germany's Johannes Ludwig took the bronze.
"Hi everyone this is United States luge racer Chris Mazdzer ok bye", Buzzfeed reporter David Muck brought Mazbdzer's good looks to the internet's attention on Saturday.
Mazdzer's USA teammates didn't fare quite as well.
