Usain Bolt has clear path to defending world title in 100 with Powell, Gay out

DAEGU, South Korea - Usain Bolt promises more antics and more amusement when the always entertaining sprinter takes the track at the world championships.

As for more records, well, the Jamaican sensation thinks that might be a bit of a stretch.

Bolt isn't anywhere near his record-setting form of 2009, when he shattered his own marks in the 100 and 200 metres. Calling this his "comeback season," Bolt downplayed expectations Thursday.

He's contending with nagging injuries, which have crimped his training.

Tiptop shape or not, Bolt has a clear path in the 100, especially with Asafa Powell withdrawing because of a lingering groin injury and American rival Tyson Gay already sidelined due to a surgically repaired hip.
