World champion Tyson Gay of the United States was out of the men's 100 meters finals in the Beijing Olympic Games with an disappointing 10.05 seconds in the semifinals.

The triple world champion in the men's 100m, 200m and 4x100m relay in 2007 in Osaka, Japan, said that "I was upset to lose this game. I had a good start and tried to save some energy in the first half, but found it too late to catch up others later on."

Many thought Gay might get injured during the fierce semifinal competition because he just recovered from hamstring injuries. He said, "Everybody tried to find excuses for me. But I don't think hamstring is a problem. It doesn't hurt."

Jamaican world record holder Usain Bolt, who led all qualifiers for the finals in 9.85 seconds, and his countryman Asafa Powell, who finished in 9.91 seconds, will both line up for the men's 100m sprint final later Saturday evening.

When commenting on the superb performance of Jamaican sprinters, Gay said, "I don't think there's a doping problem. Everybody is clean."

Gay said, "I'll continue doing in the relay."

Due to his injuries during the US Olympic trials in late June, Gay failed to make the U.S. 200m Olympian sprinters. He, however, is expected to defend the U.S. crown in the men's 4x100 relay.
