The USA completed a sweep of the 4x100m Relay titles when the quartet of Michael Granger, Charles Silmon, Eric Harris and Oliver Bradwell ran 38.93, the second-fastest time ever for a junior team.
Granger, 4th in the 100m final earlier this week, got the U.S. team into the lead on the first leg, and they were never headed. Granger in lane 6 handed off to Charles Silmon, who won silver in that 100m final, and the pair put away the Jamaican quartet before the second exchange. Bradwell got the baton on the homestretch with daylight between himself and the field, and although he was never threatened he sensibly waited until after crossing the line to celebrate the win.
The Jamaican team of Brandon Tomlinson, Bernard Brady, Odane Skeen and Dexter Lee ran strongly in lane 3, but Lee was given too much ground to make up and they finished second in 39.55. Trinidad and Tobago's quartet, just outside Jamaica in lane four, took third in 39.72. Jamol James, Sabian Cox, Moriba Morain and Shermund Allsop made up the Trinidadian team.
Japan was fourth in 39.89.
The team from Great Britain and Northern Ireland, in lane 2, failed to complete their first handoff, with Jordan Huggins unable to connect with Daniel Talbot. The Nigerian team in lane 7 was disqualified for a lane violation.
