Usain Bolt is perfect again.

And with three gold medals in Moscow, the Jamaican great became the most successful athlete in the 30-year history of the world championships.

The 4x100-meter relay gold Sunday erased the memories of the 100 title he missed out on in South Korea two years ago because of a false start. And, combined with an identical 100-200-relay triple from Shelly-Ann Fraser-Pryce, Bolt was instrumental in giving Jamaica the first sweep of the six sprint events.

Bolt was still trailing Justin Gatlin when he got the baton on the anchor leg, but a botched U.S. handover and his superior speed were enough to carry him, and Jamaica, to victory.

He gritted his teeth, dipped at the line, and then grinned with relief.
