US Olympic track and field trials highlights: Athing Mu falls, Anna Hall wins heptathlon

The defending Olympic gold medalist in the 800, Mu is a charismatic 22-year-old with a loping stride and history of building huge leads in her race. But Monday in her final she tripped as the runner pack narrowed and fell to the ground. She recovered as quickly as possible, but couldn’t make up lost time, finishing in last place. Sobbing as soon as she crossed the finish line, she declined to speak with media. Elsewhere on the track, America’s new favorite sprinter, 16-year-old Quincy Wilson, finished sixth in the men’s 400. He will not go to Paris in his individual event but there is a chance he could be put in the 4×400 relay pool. Wilson said he and his coach are awaiting word on if his season is over or not.
