Handoff costs U.S. gold in 400 relay

ATHENS, Greece -- A sloppy handoff in the men's 400-meter relay forced the United States to settle for silver, one hundredth of a second behind Britain.

U.S. anchor Maurice Greene took the baton in second place and with a burst of speed in the final 30 meters, made up some of the gap behind Britain's Mark Lewis-Francis -- but just failed to catch him. The British won in 38.07 seconds, and the Americans won silver in 38.08. Nigeria took the bronze.

The U.S. relay was undermined by a poor handoff from its second runner, 100-meter gold medalist Justin Gatlin, to Coby Miller.

The United States swept the 1,600-meter relays.

The men's team -- Otis Harris, Derrick Brew, Jeremy Wariner and Darold Williamson -- handily won gold in 2 minutes, 55.91 seconds.

The women's 1,600 relay team of DeeDee Trotter, Monique Henderson, Sanya Richards and Monique Hennagan won in 3:19.01.
