NOT even a rainstorm could stop the lightning as Usain Bolt regained his 100 metres title at the World Athletics Championships at the Luzhniki Stadium in impressive style last night - and he could be coming to Glasgow next summer.

After an opening weekend of hot sunshine in Moscow, the heavens decided to open prior to the blue riband final of the championships, but that did not seem to affect the fastest man of all time as he eased to a sixth global title.

Bolt's winning time of 9.77 seconds was nowhere near his world record of 9.58, but it was still a season's best and too good for his rivals in the wet conditions, including England's James Dasaolu.

American Justin Gatlin claimed silver, his first medal since returning from a four-year drug ban, in a time of 9.85, and he matched Bolt over the opening 30 metres. But once the Jamaican found his stride the result was never in doubt.

A false start in Daegu two years ago robbed Bolt of the chance to defend his world title, but the 26-year-old admitted it felt great to have it back while refusing to rule out challenging for the Commonwealth title next year in Glasgow.

"This is right up there for me, it feels great to reclaim my title because I gave it away last time," he said. "I knew that they were going to be fast starters and that Justin was going to get out quickly. The rain did not affect me at all; we have run in colder conditions than that over the years.

"I have never been to the Commonwealth Games. It's something I'm thinking about but I don't know if I'm going to go yet. It would be something to add to my resume. We'll see."

Dasaolu struggled in the conditions, coming home in eighth and last in a time of 10.21. But after a 9.91 at the British Championships last month and a 9.97 in the semi-finals in Moscow, he was all smiles after the race.

"Running sub-ten seconds again and making a World Championship final was brilliant," said Dasaolu, who saw compatriots Harry Aikines-Aryeetey and Dwain Chambers fail to escape their semi-finals.

Elsewhere, Christine Ohuruogu looks on course for a medal in today's 400m final after winning her semi-final in a season's best of 49.75 to go through as second fastest.

Andrew Osagie will also strut his stuff in a final after reaching tomorrow's 800m as one of the fastest losers, a season's best 1:44.85 enough for him to squeeze through after an anxious wait.

"If you had said to me last week that I was going to get to the final I probably would have said 'no way'," said Osagie. "I'm really looking forward to Tuesday to see what I can get."

However, fellow-Brit Michael Rimmer was not so lucky after finishing his 800m heat sixth, while Shara Proctor finished in the same position in the women's long jump final. The latter had the added pain of realising that her qualifying effort of 6.85m 24 hours earlier would have been good enough for a bronze medal, and the 24-year-old admitted that fact was scant consolation.

"I was feeling good until the first jump but my calf started to cramp up," she said. "I didn't come all this way to give up, so I kept pushing. As an athlete you have to have a short-term memory, qualifying was in the past and I forgot about it and came with a new mind-set to win a medal, but it just didn't happen."

In the morning session, Laura Weightman also suffered disappointment as she failed to escape her 1500m heat, finishing 11th. However there was better news for Hannah England, the world silver medallist from 2011 finishing third in her heat to progress, while Nigel Levine and Asha Philip both qualified for the next rounds of the 400m and 100m respectively.
