Tucker West's Olympic medal chances took a big hit Saturday in Pyeongchang, South Korea.

A disappointing first run left the 22-year-old Ridgefield native 26th (out of 40 competitors) in the men's singles luge event. West did improve on his second run, placing 15th, and moving up to 18th in the combined standings going into the final two runs on Sunday.

The medal winners are determined by the combined times from the four runs.

In his first run, West had the fastest start (2.545 seconds) among all 40 racers and the third best time through the second split. But difficulties on the lower half of the course cost West, who finished with a time of 48.484 seconds, 0.832 behind first-run leader David Gleirscher of Austria.

Although his start (2.577) was slightly slower on his second run, West improved the rest of the way, recording a time of 47.942 seconds to place 15th.

West's combined time of 1:36.426 from his first two runs have him 18th overall entering the final two runs. After the third run, the top-20 competitors advance to the fourth run.

Two-time gold medalist Felix Loch of Germany is first with a time of 1:35.299 following the opening two runs. Gleirscher is second (1:35.487) and Roman Repilov of Russia (competing under the Olympic Athletes of Russia banner) is third (1:35.516).

West's USA teammate, Chris Mazdzer, is fourth overall through the first two runs (1:35.517) and has a chance to become the first American to win a medal in men's singles luge.

The third U.S. competitor, Taylor Morris, is 23rd overall going into the final two runs.
