Eugene: Athing Mu of the United States competes during the women's 800 metres heat at the World Athletics Championships in Eugene.
In a World Championships already boasting some notable clean sweeps, the United States remained in the hunt for a first 1-2-3 in the women's 800 metres after their big three, led by Olympic champion Athing Mu, advanced from Thursday's heats.
Mu, Raevyn Rogers and Ajee Wilson all looked good, while Kenya's Mary Moraa and Tokyo Olympic silver medallist Keely Hodgkinson of Britain, the only other athletes to have gone under 1:58s this season, also went through on a warm, humid night.
Mu, 20, has enjoyed a stellar first half of the season, albeit with her best time two seconds down on her 1:55.04 seconds personal best set on the same Hayward Field track almost a year ago.
