VALENCIA, Spain — Bryan Clay, a Castle High alum now living in Glendora, Calif., won gold in the heptathlon today at the World Indoor Championships after Olympic champion Roman Sebrle withdrew because of injury.

Clay won four of the seven events, including the 60-meter hurdles today, scoring a personal best 6,371 points for his second world title.

Andrei Krauchanka of Belarus was second with 6,234 points and Dimitriy Karpov of Kazakhstan third with 6,131. Donovan Kilmartin, Clay's U.S. teammate, was fifth with 5,951.

Clay was pleased with the results after dealing with the flu — he recently dropped 12 pounds — and an injured hamstring.

"If you had asked me two weeks ago if I would be here, I probably would have told you I wouldn't be at this meet," said Clay, who was invited after failing to qualify. "This just shows how well my training has been going."

The 28-year-old Clay won the decathlon in Helsinki, Finland, in 2005. It was Clay's first world indoor title, finishing second in 2004 and 2006.

Clay won the 60-meter hurdles in a 7.86 seconds. Andres Raja of Estonia was second in 8.03. Sebrle, the world decathlon record holder, hit the second hurdle hard and apparently injured his left hamstring. Sebrle was carried off on a stretcher and forced to drop out.

Clay finished second to Sebrle in the decathlon in the 2004 Olympics.

In the pole vault, Clay finished fourth, clearing 5 meters (16 feet, 5 inches). Krauchanka of Belarus was first with 5.3, followed by Karpov (5.20) and Donovan Kilmartin of the United States (5.10).

Clay could have set a new point record by running under 2 minutes, 45.47 seconds in the final 1,000-meter event. He struggled to a last-place time of 2:55.64 — still a season best. Mikhail Loqvinecko of Russia won in 2:44.69.

Yesterday, Clay opened the competition by winning the 60 meters, the long jump and the shot put, and placed third in the high jump. Clay amassed 3,736 points to lead Sebrle (3,562) on the first day.
