 Greene blamed tiredness for his defeat in the 100m |
Olympic 100m champion Maurice Greene suffered a shock defeat when he was beaten by Francis Obikwelu at the Paris Golden League meeting. Obikwelu, who was born in Nigeria but now represents Portugal, clocked a time of 10.06 seconds to Greene's 10.14.
Greene never looked comfortable but just managed to hold off the challenge of Ghana's Aziz Zakari for second.
Obikwelu also won the 200m, clocking 20.12secs to edge out American Joshua J. Johnson and Frankie Fredericks.
"Of course it's a disappointment but I knew it was going to be hard as I only arrived here two days ago," Greene explained.
"My body is very tired, which you will have seen from my time."
Obikwelu refused to get carried away by his success.
 | The race went well considering I was still injured two weeks ago  |
"The race went well today considering I was still injured two weeks ago," he said.
World champion Felix Sanchez remained on course for a share of the $1m jackpot on offer to athletes who win each of their designated Golden League events.
He won the 400m hurdles in 47.99secs, finishing ahead of France's Naman Keita and Japan's Dai Tamesue.
Sanchez is one of five athletes still in contention for the big-money prize.
Bahamas star Tonique Williams-Darling (400m), Lithuania's Virgilijus Alekna (men's discus) and Sweden's Christian Olsson (triple jump) were all easy winners.
However, South African high jumper Hestrie Cloete needed a sudden death duel with Viktoriya Styopina to stay in with a chance.
Kenyans dominated both the men's 1500m and the women's 3000m, claiming the first three places in both events.
Bernard Lagat clocked three minutes 29.21 seconds - the fastest time this season - to finish ahead of Timothy Kiptanui and Cornelius Chirchir.
Isabella Ochichi set a new season record of 8:31.32 in the women's 3000m.
 | I'm not quick enough and need to get more speed and blow out the tubes  |
She crossed the finish line more than 10 seconds ahead of Alice Timbilili and Sally Barsosio.
In the women's 1500m, Hayley Tullett, Britain's world bronze medallist, was narrowly beaten by Hungary's Judit Varga.
"I'm not quick enough and need to get more speed and blow out the tubes," said the 31-year-old part-time schoolteacher, who was overtaken in the last 50m.
Tullett, whose Olympic preparations were interrupted by a hamstring tear to her right leg in early June, had not planned on competing in the French capital.
"I've had to come out and race to get ready for the Olympics," said the Welsh star.
Fellow Briton Phillips Idowu, back from a hamstring injury, failed to make the last eight cut in the triple jump.
The Sydney Olympic finalist cleared only 16.19m after producing only one valid clearance from his three attempts.
