Xu sets world record, wins third straight 50m butterfly S6 gold

China's Xu Qing broke his own world record to win his third straight Paralympic 50m butterfly S6 gold medal in Rio on Friday.

The 23-year-old finished in 29.89 seconds to beat the record he set at the London 2012 Games by one hundredth of a second.

It was a clean sweep of the medals for China with Zheng Tao taking silver in 29.93 and Wang Lichao bronze in 30.95.

"I didn't expect that. It has been my record for four years, I didn't think I would go that fast again," said Xu, who has now won eight Paralympic gold medals.

"This is the best reply to my friends and family because for a long time they have been trying to convince me not to race, to retire, but this gold shows that I was right."

Xu, who lost both arms after a car crash when he was six, said he was unsure if he would compete at the Tokyo 2020 Games.

"It might be my last Games, it depends on the condition of my body. I might do another if I feel it. But probably not." Endit
