EUGENE, Ore. — Tyson Gay fell behind early, only to make up ground in a hurry to win the 100 meters at the U.S. championships Friday night.

Gay finished in 9.87 seconds to secure a spot at the world championships in Beijing later this summer. Gay flew past Baylor standout Trayvon Bromell and then sidestepped cameramen on the track as he applied the brakes.

Michael Rodgers was third to join Gay, Bromell and Justin Gatlin on the world squad. Gatlin didn’t compete because he had an automatic bye courtesy of his Diamond League title.

Gay, 32, hasn’t competed at worlds since 2009. He missed the 2011 competition because of a hip injury and withdrew in 2013 after failing a drug test that resulted in a one-year suspension.

Tori Bowie used a late surge to sneak by English Gardner in the women’s 100, taking the crown in 10.81. Jasmine Todd wound up third, while Carmelita Jeter, the 2011 world champion, finished seventh.

Other winners Friday included Erik Kynard in the men’s high jump, Trey Hardee in the decathlon, Christina Epps in the women’s triple jump and Kara Winger in the women’s javelin.

Two-time Olympian Jenny Simpson posted the fastest time in the women’s 1,500 meter prelims, and Rachel Schneider of Sanford also advanced to Sunday’s final. Running in the fastest of three heats, Simpson won with a time of 4:08.55. Schneider was fifth in 4:09.12.

In the men’s steeplechase, Henry Sterling of Freeport ran a 9:11.05 in his heat and did not advance to the final.

Hardee, a two-time decathlon world champion, led by only 33 points after the first day of competition but dominated the second day, finishing also 500 points ahead of runner-up Jeremy Taiwo. Zach Ziemek finished third.

DOUBLE OLYMPIC champion Mo Farah will continue working with Alberto Salazar, saying he was satisfied with the response given by the American long-distance running coach to accusations of doping.

“As someone I’ve worked with for many years, I feel I have to believe in Alberto and the evidence he has provided,” Farah said on his Facebook page.

Salazar issued a 12,000-word rebuttal of claims against himself and his other star runner, Olympic silver medalist Galen Rupp, in an open letter on the website of the Nike Oregon Project on Wednesday.

Salazar, one of the world’s top track coaches, has been accused by American investigative website ProPublica and the BBC of using doping practices for his athletes in Oregon.

“Although it’s been a difficult time,” Farah said, “I asked Alberto to respond to the allegations made against him and he has now done so in full.”
