Kazan: China`s Ning Zetao was the shock winner of the men`s 100m freestyle gold at the world swimming championships on Thursday as Australia`s Cameron McEvoy had to settle for silver.
Ning touched the wall in 47.84 seconds as McEvoy, who had been fastest in the heats and semi-finals, finished second at 0.11sec with Argentina`s Federico Grabich earning bronze at 0.28.
Olympic champion Nathan Adrian of the United States finished seventh at 0.47 back.
Ning was banned for a year after failing a doping test in March 2011 for taking the performance-enhancing drug Clenbuterol.
He has won his first world title having picked up gold in the 50m and 100m freestyle at last year`s Asian Games.
McEvoy was delighted with his first individual medal at a world championships, having won a 4x100m freestyle relay silver in 2013.
"It`s exciting, it puts me in a good position to be in for the year to come," said the 21-year-old after compatriot James Magnussen, the 2013 world champion, was ruled out of the Kazan with a shoulder injury.
"I can`t be disappointed with the placing, it`s the best I ever had, a world silver medal.
"Thinking back a couple of years ago it was out of reach for me so to be in this position now especially with a year to go, it`s exciting."
