Eugene (Oregon), Jun 1 (IANS): Grenada's Olympic champion Kirani James stormed to a world-leading time as he won his first major 400 metres duel of the year with American Lashawn Merritt at the Prefontaine Classic here.
The 21-year-old James clocked 43.97 - the same time as Merritt - as he barely edged out the world champion in a close finish at Hayward Field, in the third meet of the lucrative IAAF Diamond League series Saturday, reports CMC.
"We'll go at it many more times," Merritt said.
Youssef Ahmed Masrahi of Saudi Arabia finished third in a season-best 44.77 seconds while Bahamian Chris Brown also posted a season-best 45.15 as he came home fourth.
There was disappointment for World silver medallist Tony McQuay, however, as the American finished down the field in seventh, in a time of 46.25 seconds.
The result for James was a reversal of last year's finish at the event when Merritt took the tape first with James second.
