Paris, July 18 (DPA) Jamaican Usain Bolt flew to a personal season best 9.79 seconds over 100 metres in the rain at the final Golden League series stop ahead of the world championships.

The three-time Olympic champion and world record holder Bolt Friday moved ahead at the halfway mark of the race as he improved his previous 2009 time of 9.88 seconds by nine hundredth in the Stade de France.

Daniel Bailey of Antigua and Yohan Blake of Jamaica ran personal bests of 9.91 and 9.93 seconds, respectively, to finish behind Bolt.

Bolt moved within two hundredth of the world-leading 9.77 seconds American world champion Tyson Gay ran last week in much better conditions in Rome.

'I'm happy ... In these conditions, the time is great. But it was hard to put everything in place, from start to finish,' said Bolt.

'I had a good feeling on the track, it was like flying.'

Bolt also had his best 200 m of the year in the rain, 19.59 seconds earlier this month in Lausanne, Switzerland. His 100m world record stands at 9.69 and the 200 m mark at 19.30 seconds.

Bolt and Gay have not run against each other this year with the big showdown set for the Aug 15-23 worlds in Berlin.

They will complete their tuneup next weekend in London, where Bolt will run the 100m and 4x100 m while Gay has a 200 m race there.

Meanwhile, Yelena Isinbayeva required just one jump Friday to move within two victories of a $1-million dollar Golden League jackpot along Jamaican sprinter Kerron Stewart, American 400 m runner Sanya Richards and Ethiopian distance runner Kenenisa Bekele.

The four athletes have won their event at the first four Golden League stops (Berlin, Oslo, Rome, Paris), with the meets in Zurich and Brussels to follow after the worlds.

Six-time winners win or share the full jackpot. If no athlete manages six victories, $500,000 are won or shared by five-time winners.
