Jamaica wins the 4x100 relay

It's not much of a stretch to say that this was the one race the Jamaican fans craved victory in the most. Today, they finally got it.

The United States carried an 8-0 record into the men's 4x100-meter relay, and it looked for a while like they might stay undefeated.

Then Jamaica took over in the third leg. USA Blue's Shawn Crawford tried to make a charge in the anchor leg, but Jamaica's Dwight Thomas held on for perhaps the country's biggest ever Penn Relays victory.

And now the Jamaican fans are belting out their national anthem, chanting, "Jamaica, WOO!"

1. Jamaica, 39.04 (Marvin Anderson, Michael Frater, Nesta Carter, Dwight Thomas)
