Walk in the rain for Bolt

The Jamaican world record holder, competing over the distance for the first time in 13 months, danced around in the rain as the announcer read out his name before blazing out of the blocks at the gun. He powered away around the bend before cruising over the finish line.

Norwegian sprinter Jaysuma Saidy Ndure was second in 20.43 on the Bislett Stadium track where he previously trained as a club athlete. Mario Forsythe of Jamaica came in third in 20.49.

Asked if he was back in business, a grinning Bolt told a news conference: "I was never out of business. Business was just a little slow for a while. The 200-metre is my favourite event and I'm glad it went well. Now I'm just concentrating on staying injury-free."

The weather played havoc with many of the events as athletes tried to avoid a soaking in the heavy showers. South African Caster Semenya did not find the cool, damp conditions to her liking and seemed to lack power coming off the final bend. She finished third in the 800M despite posting her best time of the season, 1:58:61.

Finland's Tero Pitkaemaeki also suffered, coming fifth in the javelin event with a throw of 80.22. Germany's Matthias De Zordo struck gold with a throw of 83.94, well ahead of South African Robert Oosthuizen in second on 82.07.

The loudest cheers of the evening were reserved for local favourite Christina Vukicevic, who won the women's 100M hurdles in a season-best time of 12.79.  She beat the American pairing of Kristi Castlin (12.95) and Nichole Denby (13.06).
