BEIJING - The United States has set a world record in the men’s Olympic 400-meter freestyle relay preliminaries.

The team of Nathan Adrian, Cullen Jones, Ben Wildman-Tobriner and Matt Grevers won their heat Sunday night in 3 minutes, 12.23 seconds, erasing the old mark of 3:12.46 set by the U.S. at the 2006 Pan Pacific championships in Victoria, British Columbia.

The U.S. has not won the event at the Olympics since 1996, taking silver in 2000 and bronze in 2004.
