Update, July 10: Delilah Muhammad, an NCAA All-American, broke from the field early, winning by more than a second in 52.88. The 26-year-old secured a bid to her first Olympics by clocking the fifth-fastest American time for a woman ever in the event. Ashley Spencer, 24, took second in 54.02. But the biggest ovation came for 16-year-old Sydney McLaughlin, who took third at 54.15, setting a junior world record. She will be the youngest American track athlete in Rio.

Cassandra Tate, 25, was right behind her at world championships in Beijing, earning bronze. Other top contenders include Delilah Muhammad, 26, a world championships silver medalist in 2013; Georganne Moline, 26, the runnerup at the 2012 Olympic Trials; and veterans Lashinda Demus, 33, and Tiffany Williams, 33.
