US athlete Ashton Eaton has set a new world record in decathlon at the national Olympic trials.
The 24-year-old notched 9,039 points, which beat the previous best - set in 2001 by Roman Sebrle - by 13 points.
The 24-year-old told USATF.org: "It is a representation of all the work I have put in. I love this field and it's special for it to happen here."
In contrast, Beijing gold medallist Bryan Clay fell during the hurdles and finished 12th after also struggling in the discus.
Allyson Felix's participation in the 100m at London 2012 is up in the air after she ran a dead-heat with Jeneba Tarmoh for third spot in Oregon.
The Games in London begin on July 27.
