Josette Norris's great 2021 continued as she defeated Konstanze "Koko" Klosterhalfen who returned from injury in her final race before the Olympics.

Mu's magical 2021 continued as she ran a Trials record and US #2 time of 1:56.07 thanks to an incredible 28.49 final 200. Behind her, Raevyn Rogers and Ajee Wilson came from way back to grab their tickets to Tokyo in a super competitive race where 5 of the top 6 ran lifetime bests.

The fastest two Americans in history Evan Jager and Stanley Kebenei have both scratched and Andy Bayer (#7 all time) is retired.

And Benard Keter just beat McGorty.

Donavan Brazier is the reigning world champ but he's never made an Olympic team. Bryce Hoppel was 4th at Worlds in 2019 but just was a DNS in Boston.
