Powell names Bolt, not Gay, as his main Olympic rival

PORT OF SPAIN, Trinidad: Former world 100m world record holder Asafa Powell is looking no further than this weekend's Jamaican national championships to find his biggest challenger for Olympic gold.

"(Usain Bolt) is my main rival," said Powell, picking his compatriot over American world champion Tyson Gay after a confidence-boosting run of 9.96 seconds at the Trinidad national championships on Saturday.

The race was Powell's first since an April shoulder injury and set the stage for a clash with new world record holder Bolt on Friday through Sunday in the Jamaican championships in Kingston.
