Former world record holder Asafa Powell (centre) won the 100 metres final at the London grand prix on Friday in 9.94 seconds running into a slight head wind.
Powell lost his world mark this year to compatriot Usain Bolt, who runs in his specialist 200 event on the second day of the meeting on Saturday. Bolt has yet to decide if he will attempt a 100-200 double at next month's Beijing Olympics.
American world champion Tyson Gay, who beat Powell into third place at last year's world championships, was scheduled to run the 100 but withdrew after aggravating a hamstring strain.
"I felt very confident, very relaxed," Commonwealth champion Powell told reporters. "I could definitely have gone a bit quicker. With or without Usain I'm going for the gold medal."
