Jamaica's Shelly-Ann Fraser-Pryce made it a sprint double with victory in the 200m, as Olympic champion Allyson Felix failed to finish because of an injury.
Fraser-Pryce, second behind Felix at the London Games, clocked 22.17 seconds to finish ahead of Murielle Ahoure of the Ivory Coast and Nigeria's Blessing Okagbare (both 22.32).
Felix dropped to the track early in the race grabbing her torn right hamstring.
The United States won the men's 4x400m ahead of Jamaica and Russia.
David Verburg, Tony McQuay, Arman Hall and LaShawn Merritt won the race in two minutes, 58.71 seconds. Jamaica clocked 2:59.88 and Russia 2:59.90, with Great Britain fourth in 3:00.88.
Three-time champion Felix was chasing a record ninth gold medal but she is unlikely to feature in the American team for the final of the women's 4x100m.
