ZURICH: Olympic 800m champion David Rudisha suffered a shock defeat at the Weltklasse Diamond League meeting on Thursday but Usain Bolt braved the cold to win the 200m in a meeting record time.

Kenyan Rudisha, who set a world record to win gold in London, lost out to Ethiopian teenager Mohammed Aman on a chilly wet evening at Zurich’s Letzigrund.

Double Olympic silver medallist Yohan Blake refused to be daunted by the conditions as he ran another fast time to win the 100m in 9.76 seconds, while Olympic 400m hurdles champion Felix Sanchez said he just wanted to lie on the beach after finishing fourth on his 35th birthday.

Rudisha, assisted by a pacemaker, sped away on the first lap but clearly went too early as the pack caught up with him around 200m from the end and Aman passed him on the curve to win in one minute 42.53.

“My legs felt tired and I cannot run well if the weather is not good,” said the 23-year-old, running in his only post-Olympic race of the year.

“I hoped for a fast race here and I’m a little disappointed ... It was the rain which stopped me.”

“It was a difficult race but I was in good shape,” said Aman, sixth in London.

Double Olympic champion Bolt had no such problems as he won the 200m in a very respectable 19.66 seconds, again making it look easy as he powered ahead of fellow Jamaicans Nickel Ashmeade and Jason Young. Bolt jokingly made shivering gestures before leaving the opposition in his wake in familiar style.

“I’m happy to run a sub-20 time but I did not want to push my body,” said Bolt. “It is the end of the of the season and I have to be careful.”

Former world champion Tyson Gay was disqualified for a false start as Blake, who ran the joint third-fastest time in history in Lausanne last week, won the 100m in another impressive time.

His fellow Jamaican Nesta Carter was second in 9.95 and American Ryan Bailey third in 9.97.

Olympic champion Shelly-Ann Fraser-Pryce easily won women’s 100m, beating Carmelita Jeter into second place after losing out to the American silver medallist in Lausanne and Birmingham.

Sanchez was beaten into fourth place despite a late charge in the 400m hurdles, won by American Angelo Taylor in 48.29.

Olympic champion Sanya Richards-Ross won the women’s 400m in 50.21 seconds ahead of Botswana’s Amantle Montsho.

Croatia’s Olympic gold medallist Sandra Perkovic won the women’s discus but Olympic long jump champion Brittney Reese retired injured In her event, saying she had aggravated a tress fracture in her left ankle. — Reuters
