YOKOHAMA, Japan -- World 100m record holder Asafa Powell pulled up with a hamstring injury in a 200m race in Yokohama, ending his season disappointingly.
Powell pulls up suddenly as he feels the hamstring.
The Jamaican, who broke the 100m world record with a run of 9.74 seconds in Italy earlier this month, was soon in trouble in the rain.
He came to a sudden halt, allowing American JJ Johnson to romp away to victory in 20.64, followed by Canadian Tyler Christopher and Japanese Hitoshi Saito.
Powell's manager Paul Doyle said: "He was coming off the turn and he felt pain in the upper hamstring. The pain immediately moved to the belly of the hamstring and he stopped running immediately.
"He is in a lot of pain right now."
World champion Tyson Gay said he would the 100m world record next season after finishing this campaign with a comfortable victory.
The American won 100m in 10.23 seconds against wind and rain, followed by Churandy Martina of the Dutch Antilles and Naoki Tsukahara of Japan.
Gay, a triple sprint champion at the Osaka world championships, said he would concentrate on outdoor events in the warm-up for the Beijing Olympics in an effort to beat Powell's mark.. E-mail to a friend
