SOCHI, Russia -- Viktor Ahn put himself in position to give his adopted Russia its second short track medal after winning his semifinal in the 1,000. The South Korean-born skater who became a Russian citizen two years ago already has a bronze at Sochi after finishing third in the 1,500. His teammate, Vladimir Grigorev, won the other semi to advance in the 1,000.
Americans J.R. Celski and Eddy Alvarez were eliminated in separate crashes during the quarterfinals Saturday at the Iceberg Skating Palace.
Also making the final later Saturday were Sin Da-woon of South Korea and Wu Dajing of China. Sjinkie Knegt of the Netherlands progressed to the final after Lee Han-bin of South Korea was disqualified.
Celski clipped a lane marker in a turn and went down while racing second in the last of four quarterfinals. Alvarez was taken out by 1,500 Olympic champion Charles Hamelin of Canada, who also crashed out. Alvarez got up and finished skating while holding his face, apparently injured in the crash.
"I was just kind of building up some speed a little bit, hanging on his outer hip, and he just went down," Alvarez said. "I was in a bad place at the wrong time. It's part of the sport."
