Usain Bolt continued to rebuild his air of invincibility with a peerless victory in the men's 100 metres in an IAAF World Challenge meet here Tuesday.

The World sprint king from Jamaica put his false-start disqualification at the recent World Championships in Daegu, South Korea, firmly behind him, when he clocked a season's best 9.85 seconds in the first 100 metres he has contested since that ill-fated trip to the start line.
