World 800m champion Donavan Brazier didn’t qualify for the Tokyo Olympics after ending final on the make-or-break US trials.
The US file holder, who received gold in Doha in 2019, ran out of power in the ultimate 200m and completed greater than 4 seconds behind winner Clayton Murphy.
Olympic bronze medallist Clayton set a brand new world lead of 1 minute 43.17 seconds, with Isaiah Jewett second.
Brazier, 24, stated he “made a move a little too early”.
“I’m very sad. I knew with about 200 left when Clayton passed me and I couldn’t match it,” he stated.
“I’m having some things bugging me, but they’re things that someone of championship calibre should be able to push through and nothing that I can make excuses for this race.
“I’ll come again from this. I’ve been down worse earlier than.”
Elsewhere on Monday, world champion and Rio 2016 bronze medal-winning pole vaulter Sam Kendricks reached his second Olympics but had to settle for a two-way tie for second with KC Lightfoot behind Chris Nilsen, who cleared 5.90m.
Two-time Olympic silver medallist Will Claye won the triple jump with 17.21m, capping a remarkable comeback after rupturing his Achilles last year.
“It has been a extremely tough yr for me,” he stated.
Rising star Elle Purrier St Pierre won the women’s 1500m in three minutes 58.03 seconds but Rio bronze medallist Jenny Simpson missed out on her fourth Olympics, finishing 10th in the same race.
