LONDON (USA Today) -Usain Bolt's legend continues to grow.
The Jamaican superstar anchored Jamaica to victory in the 4x100 relay Saturday night in a world-record 36.84 seconds at Olympic Stadium to capture his third gold medal of the London Games.
He's unbeaten as an Olympian, winning the 100, 200 and 4x100 relay at back-to-back Games.
Nesta Carter, Michael Frater and Yohan Blake - the silver medalist at 100 and 200 - passed the baton efficiently and fast and then left it to Bolt.
The U.S. lineup of Trell Kimmons, Justin Gatlin, Tyson Gay and Ryan Bailey finished second at 37.04, breaking the one-day old American record set Friday in the preliminary heat and tying the old world record.
The USA had no problem passing the baton, which had been an issue of late in major championships. Bailey, in fact, had a slight advantage when he took the stick from Gay, but Bolt, being Bolt, blew past him and into bedlam.
There was a delay of a couple of minutes before the official results were posted because of a challenge. Canada, which initially came across in third place, was disqualified, elevating Trinidad to the bronze medal.
Bolt has been talking all week about becoming a legend.
The head of the IAAF, Lamine Diack, agrees, saying Bolt "entered the legendary" after retaining his Olympic titles in the 100 and 200.
The Games' head organizer, Sebastian Coe, called Bolt "a powerful influence."
Coe also has no problem with Bolt's showmanship and says, "It's great that our sport captures those great moments."
