CARSON, Calif. (AP) – Justin Gatlin cemented his status as America’s fastest human Sunday by winning the 200 meters, becoming the first man in 20 years to sweep the sprints at the U.S. track and field championships.

A day after winning the 100, Gatlin turned it on down the stretch to win the 200 in 20.04 seconds. The last man to win both races at the U.S. meet was Kirk Baptiste in 1985. Tyson Gay, just out of Arkansas, was second in 20.06, followed by the Olympic gold medalist in the event, Shawn Crawford, in 20.12.

Wallace Spearmon, who has the world’s fastest time in the event this year in 19.91, finished fourth at 20.16 and failed to make the U.S. team for the world championships in Helsinki Aug. 6-14. The men’s 200, into a head wind, was the last event of the four-day competition at Home Depot Center.

It was a triumphant performance after a near-disastrous start for the 23-year-old Gatlin. The Olympic gold medalist in the 100 and bronze medalist in the 200 was disqualified for a false start in the 100 preliminaries Friday. He was reinstated after a protest, and took off from there.

“I had to turn it around and make sure it was a very positive experience,” Gatlin said. “I feel like I’m in my zone, like I was in college, doubling and hopefully dominating as well.”

Kerron Clement won the 400 hurdles and Allyson Felix took the women’s 200, as both 19-year-olds posted two of the most impressive championship performances from a young corps of talent that is taking over the sport in the United States. taking over the sport in the United States.

Gatlin and Felix were especially happy for each other.

“She was the only one who brought emotion out of me after the “DQ,”‘ Gatlin said. “I wouldn’t say boyfriend-girlfriend. She looked to me for advice and guidance.”

Felix, meanwhile, called Gatlin “my sidekick.”

Christian Cantwell had the best throw in the world last year, but fell apart at the Olympic trials and failed to make the team in Athens. This time, though, he won with a throw of 71 feet. Two-time Olympic silver medalist Adam Nelson was second at 70-7. Three-time world champion John Godina was third at 68-10.

Michelle Perry, an Olympian in the heptathlon last year, beat Olympic gold medalist Joanna Hayes in the 100 hurdles.

. Running into a head wind, Perry won in 12.66. Hayes was second in 12.77.

There was a bit of roller-derby action in the race with Hayes, according to Perry.

“She runs with her arms out, and I felt her arm hit me,” Perry said. “You can’t let that bother you. I just wanted to make sure I got out of the blocks because my start is very weak. I expect big things for myself this year.”

The top three finishers in each event make the U.S. team for the world championships, providing they meet qualifying standards.

Hazel Clark, the youngest of the running Clark family, won the 800 in 1:59.74 for her first outdoor championship. She won the U.S. indoor earlier this season. Her sister-in-law, five-time Olympian Jearl Clark, was a late scratch from the race.

Olympic silver medalist Matt Hemmingway won the high jump. He was one of four who cleared 7-5, but took first on fewer misses. Jesse Williams was second and Keith Moffatt third. Kyle Lancaster was fourth and failed to make the U.S. team, even though he cleared the same height as the winner.

Khadevis Robinson won the men’s 800 in 1:45.27, capturing an event he won six years ago. David Krummenacker, the 2003 world indoor champion, was second at 1:46.80.
