LONDON – Wil London got the Americans started off right, and they just kept on burning up the track from there.

The Baylor sophomore ran the leadoff leg on the United States’ 4x400-relay team at the World Championships on Saturday, and the Americans broke off the top time in the world this year at 2:59.23 in those opening heats.

The United States will run for gold on Sunday, the final day of the meet.

London busted out to a furious start and set the Americans on a hot pace before handing off to second leg Bryshon Nellum. Michael Cherry and Tony McQuay rounded out the foursome for the U.S., which was trailed by Trinidad and Tobago (2:59.35) in second and Belgium (2:59.47) in third.

Also running in the final will be France, Great Britain, Poland, Spain and Cuba. The final is slated for 3:50 p.m. Central on Sunday.
