Sebastian Crismanich brought Argentina its first gold medal of the 2012 London Olympics with a win here Friday in the men's under-80kg taekwondo final.

The Argentine, seeded seventh, upset fifth-seeded Spaniard Nico Garcia in a match that was decided in the last 20 seconds.

Crismanich not only won his country's first gold of the London Games, but the first Argentine medal of any kind in taekwondo, which became an Olympic event 12 years ago.

Spain now has four medals in taekwondo, all but one of them earned in London.

Garcia's silver follows a gold for Joel Gonzalez in the men's under-58kg. competition and Birgitte Yagüe's silver medal in the women's under-49kg category, both won on Wednesday.

"I'm excited," the 25-year-old Crismanich said after receiving the gold.

"In the moments before an Olympic Games, the mere thought of seeing the flag up above, of hearing the anthem play and of me with a medal hanging on my chest, gave me chills and made my legs shake," he said. "Now that it happens to me, it's truly more than I dreamed." EFE
