EUGENE, Ore. (AP) — Tyson Gay eased through his first 100-meter qualifying heat in the U.S. Olympic trials Saturday, winning in 10 seconds flat.

Gay, mending from a hip injury that kept him out of action for most of the past year, matched the time he ran in his return in New York earlier this month. That race was into a headwind. This time, on a rainy day in Eugene, he had a slight tailwind.

Justin Gatlin, the 2004 Olympic champion, won his heat in 9.90 seconds, keeping alive his bid to return to the Olympics after missing 2008 because of a doping ban.

In the decathlon, Ashton Eaton was on pace through nine events to break Dan O’Brien’s 20-year-old American record and still had a chance at the world record, as well.

UPDATE: Gay made the Olympic team Sunday night by coming in second to Gatlin in the 100-meter finals.
