MARQUETTE, Mich. — Lee Jung-Su of South Korea beat U.S. speedskater Apolo Anton Ohno in the men's 1,500-meter short track World Cup race on Saturday.

Lee finished in 2 minutes, 13.595 seconds and Ohno crossed in 2:13.731. Charles Hamelin of Canada was third.

"Everyone was trying to get up to the front, and there was some bumping in the action," Hamelin said. "I think I used too much energy to fight for the front and my legs were tired at the end."

Ohno was also fatigued by the end of the day.

"I'm trying to conserve as much (energy) as possible," he said. "I'm dead tired."

Katherine Reutter set an American record of 43.648 seconds in a quarterfinal heat of the women's 500 and then placed fourth in a final won by Wang Meng of China in 42.961. Canadians Kalyna and Marianne St.-Gelais took second and third, respectively.

Sung Si-Bak of South Korea set a world record of 40.651 in a preliminary heat of the men's 500, but placed third in the final won by Francois-Louis Tremblay of Canada in 42.437. Thibaut Fauconnet was second.

Ohno and fellow American Anthony Lobello were disqualified in the quarterfinals of the 500.

China took the top two spots in the women's 1,500, with Zhou Yang finishing in 2:22.700 to edge Liu Qiuhong. Lee Eun-Byul of South Korea was third.

Reutter and U.S. teammate Allison Baver failed to make the women's finals. Reutter fell in her semifinal heat and Baver finished last in hers.

The meet continues Sunday with the men's and women's 1,000 and relay races.

Saturday was the second round of qualifying for athletes to secure spots at the 2010 Olympic games in Vancouver. Results from Marquette's World Cup will be combined with last week's World Cup results from Montreal.
