Olympic preview: Doubles luge

America will have two teams seeking medals in the doubles luge event Wednesday at the PyeongChang Olympics.

The event, which consists of two heats, gets underway at 6:20 a.m. ET.

The team of Matthew Mortensen and Jayson Terdiman consistently turned in top-five performances during the six training runs earlier this week, with their fastest run ranking second in that heat.

The other American team, consisting of Justin Krewson and Andrew Sherk, struggled to break into the top 10 during the training runs, with their best run ranking eighth among the competitors.

Mortensen, a 32-year-old Long Island native, and Terdiman, a 29-year-old from Pennsylvania, are three-time national champions and rank fifth in the current World Cup standings.

The duo also competed in the 2014 Olympics, but as part of separate teams. Terdiman, paired up with Christian Niccum, finished 11th in Sochi, while Mortensen, competing with Preston Griffall, finished 14th.

Mortensen also won the silver medal in team relay in the 2017 world championships.

Krewson, a 22-year-old from Long Island, and Sherk, a 25-year-old from the Philadelphia area, are making their Olympic debuts.

The U.S. is seeking its first Olympic medal in doubles luge since winning silver and bronze at the 2002 Olympics in Salt Lake City.
