Neither Powell nor Gay were in Tuesday's race where American Darvis Patton finished second in 9.98 while Powell's compatriot and training partner Nesta Carter took third place in 10.02.

"I still have work to do on my finish and I can do better than that," Powell said. "I'm not really surprised by my time. There was no wind at all and with a slight headwind, it might have been faster. I'm feeling well, fresh."

"I believe I can," Powell added when asked whether he thought he could recapture the world record of 9.72 sec set by Bolt in New York on May 31 this year.

The women's 100m was also won by a Jamaican runner, Kerron Stewart, in 10.94. She narrowly outsprinted compatriot Sherone Simpson, who came second in 10.95. American Torri Edwards, the leading 2008 performer with 10.78, was third in 11.02.

Britain's Martin Rooney profited from the absence of US 400m masters Jeremy Wariner and LaShawn Merritt to win over one lap in a personal best 44.72 sec.

Daniel Kipchirchir Komen set a year's best of three minutes 31.49 sec for the men's 1,500m, narrowly beating compatriot Shedrack Kibet Korir, who came second in 3:31.94.

Jamaica's Melaine Walker repulsed the challenge of American Tiffany Ross-Williams to clock a year's best 53.48 sec for the women's 400m hurdles. Ross-Williams finished a close second in 53.54 with compatriot Sheena Tosta third in 53.58.
