OSLO - Sanya Richards of the US lowered her 2009 world best over 400m on Friday at the Bislett Games to stay in the hunt for the Golden League $1million jackpot.

Russian pole vaulter Yelena Isinbayeva and Ethiopian distance runner Kenenisa Bekele are also among six in the race for jackpot. The jackpot goes to athletes who win their event at all six stops of the series.

Richards won the 400m in 49.23 seconds, .34 of a second faster than in her Berlin victory. Shericka Williams of Jamaica became the second women this year to dip below 50 seconds, clocking 49.98 seconds.

Isinbayeva failed with her opening attempt of 4.71m just before the storm hit, but cleared it later after the rain to win on countback against Poland's Monika Pyrek.

Bekele, like Isinbayeva a world and Olympic champion, won the men's 5000m in a modest 13:04.87 minutes in his second race after an injury-plagued winter.

Jamaican sprinter Kerron Stewart remained in the jackpot hunt with a 100m victory in 10.99 seconds. So did US 100m hurdler Damu Cherry in 12.65 seconds, and Finnish javelin world champion Tero Pitkamaki, who had 84.63m. - Sapa-dpa
