MOSCOW When Usain Bolt means business, he is still all alone out there.
Bolt coasted to his third straight 200-meter world title, with the race basically wrapped as soon as he entered the finishing straight Saturday.
Jamaican teammate Warren Weir never got close to Bolt's world-leading mark of 19.66 seconds, but crossing .13 seconds later for silver still left him enough time to join Bolt in a reggae dance to Bob Marley's "Three Little Birds."
Curtis Mitchell of the United States took bronze in 20.24 seconds but was never in the hunt for gold.
Now Bolt will go for his fourth triple gold at a major championship when he joins the Jamaican team for the 4x100 relay Sunday.
