EUGENE - Dayone of the U.S Olympic Track & Field trials featured a world record, and seemingly record rain fall.

Oregon's Ashton Eaton set a new world best in the decathlon in the men's 100 meter dash.

His time of 10.21 gave him valuable points towards clinching a berth in the Olympic games. The decathon events continue with five more events.

In the Men's 400 meter, LaShawn Merritt's time of 45.36 was the best of the men's four heats in the preliminary rounds. He said afterwards that the rain wasn't too bad as long as you adapt to it, and know what the track is like.

Olympic 2004 gold medalist Jeremy Wariner, wasn't terribly fast, but quick enough for a top-three finish in his heat to advance to tomorrow's next round.

Sanya Richards-Ross said everything was good with her prelim run in the women's 400, with one exception. Other than messing up my hair, it was OK, joked the defending world champ.

The men's and women's 10,000 final will take place Friday night at 6:45, and 7:20 respectively.
