Trotter was not the only American to miss qualifying for the 400m finals. Countrywomen Sanya Richards and Demetria Washington also saw their runs toward medals in that event end. Richards posted a 51.32 reading to take fourth in heat one, while Washington was fourth in heat two, crossing the line just ahead of Trotter in 51.31. Tonique Williams of the Bahamas won heat two in 50.43, and that mark stood as the fastest of the semifinal round.
While their pursuits in the open 400 have ended, Trotter, Richards and Washington join Me'Lisa Barber, Julian Clay, Crystal Cox, Jearl Miles-Clark and Moushami Robinson in the talent pool for the U.S. 4x400m relay quartet. Action in that event gets underway on Saturday at 12:15 p.m. Eastern. The 4x4 finals are set for 1:10 p.m. ET on Sunday.
Former Lady Vol Kelli White, who claimed a gold medal in the 100m dash on Sunday, will begin her quest for a double on today. Heats and quarterfinals of the 200 meters are scheduled for the morning and evening, respectively. Should she continue to advance, the semifinals are on Wednesday, and the finals are on Thursday.
