Carson, Calif. ? Tyson Gay, ranked second in the world, won the men’s 100 in a wind-aided 9.79 on Sunday at the Adidas Track Classic.

The wind was rated at 2.5, over the allowable limit or else he would have tied Maurice Greene’s American record.

“When I was in the blocks, I could feel a light breeze, but I’m still satisfied with that outcome,” Gay said. “It lets me know I’m in pretty good shape.”

Derrick Atkins was the only other man under 10 seconds, finishing second in 9.86.

Kansas Citian Greene failed to advance out of the 100 heats in his first such race in a year, finishing last in 10.84.

“I don’t like to see Maurice hurt,” Gay said. “I’m expecting him to do big things at USAs.”

Greene, the 32-year-old former world-record holder who in the past has been headline performer at the Kansas Relays, missed most of last season because of a hairline fracture in his foot.

“I need to get stronger in my legs. I have no power right now,” said Greene, who trained just two weeks for the race. “I just wanted to get through this race and not hurt.

Next up for Greene will be U.S. nationals in June. “I will win,” he predicted.

Meanwhile, Meseret Defar of Ethiopia won the women’s 2-mile run with a world-record time, while pole vaulter Jenn Stuczynski and javelin thrower Breaux Greer set American records.

Olympic and world champion Jeremy Wariner won the men’s 400 and Allyson Felix, running in front of a hometown crowd, took the women’s 200.

Defar, the Olympic 5,000 champion, won in 9 minutes, 10.47 seconds, lowering the mark of 9:11.97 set by American Regina Jacobs in 1999.

Wariner won the 400 in 44.60, slower than he went this month in Osaka, Japan.

Felix, the Olympic silver medalist, easily defeated her rivals in the 200, winning in 22.18.

Stuczynski won the women’s pole vault at 15 feet, 101â2 inches, taking down Stacy Dragila’s three-year-old mark of 15-10.

Making a comeback after Achilles’ surgery a year ago, Dragila tied for last, clearing 14-03â4 once in three tries.

Dragila didn’t see her rival’s record-setting jump because she was getting treatment on a sore muscle, but she said losing her record motivates her for next month’s U.S. nationals.

“I didn’t jump high, but from where I’ve been the last couple weeks, it was a huge breakthrough,” she said.
