LONDON -- Myles Porter of the United States won the silver medal in 220-pound judo at the Paralympics on Saturday.
The blind athlete called it redemption after finishing fifth at the 2008 Beijing Games. The 26-year-old Porter was aiming for gold, but said any medal was an improvement.
"It's not the color I wanted, but silver is nothing to hang your head down about," he said after Choi Gwang-geun of South Korea won the gold medal. Brazilian Antonio Tenorio won the bronze.
Porter's teammate, Dartanyon Crockett, took bronze in the 198-pound division, winning his last fight in less than 1 minute with a throw.
Also, British swimmer Ellie Simmonds defended her title and set a new world record in the 400 freestyle S6 division. Victoria Arlen of the United States led for much of the race until Simmonds surged in the last 50 meters, leaving Arlen with silver.
Arlen originally had been reclassified into a different category but she appealed the decision. Officials ruled this week that Arlen could compete in the division until her review by the Paralympic classification panel next August.
The 17-year-old Arlen, of Exeter, N.H., is a former champion swimmer who was paralyzed in 2006 by a virus affecting her spinal cord. She was in a vegetative state for two years. Earlier this year, Arlen broke two of Simmonds' world records.
In track, South African sprinter Oscar Pistorius will defend his Beijing title in the T44 200m final on Sunday after qualifying on Saturday in the third heat.
Running on carbon-fiber blades, Pistorius became the first double amputee to compete at the Olympics last month. He won three golds at the Beijing Paralympics.
Porter, who lost to Tenorio in Beijing, said he and his coach have spent the past four years training for London.
"We've spent the last six months just focusing on the mental preparation," Porter said.
In his quarterfinal, he flipped his Japanese opponent onto his back for a match-ending ippon in just five seconds. Though he is legally blind, Porter also competes in sighted judo competitions and won silver in the U.S. national championship.
In 2010, Porter tried to join the Army after his brother enlisted, but was rejected because of his blindness. Instead, Porter focused on the London Paralympics. He spends much of his time talking to wounded U.S. veterans, encouraging them to not be limited by their physical disabilities.
Porter also gives regular judo demonstrations, including a 2009 session for President Barack Obama and first lady Michelle Obama at the White House. Porter described Obama's enthusiasm for judo as "awesome" and said the president had taken off his blazer in preparation for getting onto the judo mat.
"Then there were about 200 cameras turned on him," said Porter, noting Obama had a late change of heart.
Paralympic judo is fought only by visually impaired or blind athletes. Unlike Olympic judo, fighters start the bout with a grip on each other's uniforms, changing the pace and dynamic of the martial art.
"In Olympic judo, it's very rare to have two hands on your opponent," said U.S. Olympic coach Jimmy Pedro. "But in Paralympic judo, that's where they start."
That means Paralympic competitors are often in a better position to throw -- drawing the sport closer to its Japanese roots as a weapon-less martial art developed by samurai. In contrast, Olympic judo is often split between fighters aiming to throw and those who focus on groundwork with choking or grappling techniques. The result is often an intense battle for a superior grip, with intense grabs and blocks that sometimes resemble boxing.
"Paralympic judo is very physical because you can always feel your competitor's strength," Pedro said.
He added that starting with a grip on your competitor's uniform isn't always an advantage.
"It's possible you could get lucky and throw," he said. "But your opponent has a grip on you too."
