Sun's tragedy-tinged triumph

Superstar Sun Yang broke down in tears after dedicating his latest gold medal to his late friend Kenneth To.

Hong Kong swimmer To died last week after falling ill in the locker room while training in Florida.

"I wanted to have a great performance today because I did not swim only for myself. I wanted to try my best to honor my friend Kenneth," said an emotional Sun after winning the 400m freestyle in a world-leading 3 minutes, 43.73 seconds at the national swimming championships in Qingdao, Shandong province, on Sunday.
