Former 100m and 200m world champion Tyson Gay, along with London Olympics‘ 100m bronze medallist Justin Gatlin qualified for the second round of the US trials.
With a headwind of 2.9 metres per second the minds were set on qualifying rather than on impressive time.
While Gay won his heat in 10.28 seconds, Gatlin, facing stronger wind, clocked 10.37s, crossing the finish line behind Charles Silmon.
"I didn't really have a great start," stated Gay after the race.
"But (I wanted) to the get the kinks out, get the nerves out. I should be ready for tomorrow."
Justin Gatlin kept calm despite losing his heat.
"There was a little hurricane out there, the head wind, but it felt good to come out here and shake the legs out a little bit," reported Gatlin.
Nevertheless, two other sprinters Mike Rodgers and Walter Dix were the fastest, as both finished the race with a time of 10.19 seconds, and hope to leave behind the favourites in the semi-finals and hopefully the final on Friday.
In the 400m race, it was a bad day for multi-titled Jeremy Wariner, who after an injury comeback failed to finish the race coming in last place.
Meanwhile, in women’s track it was Barbara Bierre, former Haiti sprinter, who led the 100m tables with 11.18. The second fastest female of all-time Carmelita Jeter missed the meeting due to quadriceps problems. However, being the world champion from Daegu 2011, guarantees her an automatic entry for the 100m race this year.
Galen Rupp, silver medallist from London, won the 10km race, finishing with 28:47.32 on the clock, winning by just two seconds in front of Dathan Ritzenhein.
The selection ends this Sunday.
