[1] From the outset, new world record holder Ashton Eaton dominated the events with teammate Trey Hardee his closest competitor.
Notable for his early exit, 2004 champion and former world record holder Roman Šebrle withdrew after finishing last in the 100 m. Eaton's 10.35 100 metres was the top time of the day, Hardee's 10.42 the next best.
Hardee started day two off with a victory over Eaton in the 110 metres hurdles, but it was only .02, narrowing the gap by 3 points.
In the javelin throw, Leonel Suárez put more than 10 meters on the rest of the contenders, to solidly place himself in bronze medal position.
Hans van Alphen led the way to move into fourth place, but nobody made a serious run at improving their medals, instead choosing to just finish the last event.
