Nina Roth's Team USA rink, which includes Duluth's Aileen Geving, lost 7-3 to the Czech Republic on Sunday in Beijing, dropping the Americans into the bottom half of the World Women's Curling Championship standings.
The U.S. led Anna Kubeskova's rink 2-1 before allowing three points in the fourth end and never recovering.
"We were not as clean with our throws to really finish the shot," the 30-year-old Geving said in a news release. "That was more so in the first half (of the match). Then we got a handle on it, but we weren't quite as sharp as (Saturday)."
Team USA faces Canada and Italy in today's round-robin action.
