CHESTERFIELD, Mo. — A late crash by Apolo Anton Ohno allowed Travis Jayner to win the 500-meter final today at the U.S Short Track Speedskating Championship.

The wild finish completed a confusing race that the referee ordered rerun.

Kimberly Derrick captured a smoothly run women's final.

Ohno was in the lead when he tripped over a block coming out of the final turn of the last lap and took Jordan Malone to the ice. Jayner won in 43.958 seconds and Malone recovered to take second in 44.498. He was followed by Ohno and J.R. Celski.

Ohno fell going into the third turn during the initial running of the final and was followed to the ice by Jayner and Celski. The referee quickly whistled the race dead because he determined the results of the race would have been skewed because of the three falls.

After some confusion whether Ohno should be disqualified, the race was held again with all four competitors. Ohno, who won a gold medal in the 500 at the 2006 Olympics, took the lead from the start in the second running and held it until his late fall.

In the women's race, Derrick held the lead from the start and finished in 45.984 seconds. Maria Garcia took second in 46.032 and was followed by Alyson Dudek and Allison Baver.

Competitors earn points based on their finish in five events. The top five men and top five women will represent the U.S. at the World Cup events in February and the World Championships in Vienna in March.

Ohno has the overall lead with 2,140 points, followed by J.R. Celski and Jeffrey Simon. Derrick is first for the women with 2,200, followed by Katherine Reutter and Alyson Dudek.
