EUGENE, Ore. -- Olympic gold medalist Elaine Thompson-Herah of Jamaica held off American Sha'Carri Richardson in the 100 meters at a rainy Prefontaine Classic on Saturday.
Thompson-Herah won in the 100 and 200 and the 400 relay at the Tokyo Olympics. She defended her Pre title in 10.79 seconds, in front of Richardson in 10.92.
"I came out here with the mindset of a champion and I delivered," Thompson-Herah said, revealing that she's been battling a shoulder injury this season.
Richardson became a sensation when she won at the U.S. Olympic trials last year but was denied a spot on the team for Tokyo because she tested positive for marijuana. She returned at the Pre last year and finished last in the 100.
Richardson wore bright pink that was adorned with gold charms. She did not speak to reporters after the race, her first sub-11 second mark since last year's trials.
Runners at Hayward Field, which will host the world championships in July, were greeted with passing rain showers, temperatures in the upper-50s and breezy conditions.
American Michael Norman won the 400 in a meet-record 43.60. He won at the trials last year and finished fifth in the event at the Olympics, but now has his sights set on the worlds.
"I think it's everyone's dream to win at home, this being the first world championships in Oregon, of course it's going to be a memorable memory for any U.S. athlete," Norman said.
Trayvon Bromell raised his arms in victory before crossing the finish line of the men's 100 in 9.93 seconds. He crossed the line ahead of Fred Kerley and defending world champion Christian Coleman. Olympic champion Marcell Jacobs withdrew from the Pre earlier this week.
"For me it was personal, not against anybody in the race, but mostly for myself to show people like, 'Man, I'm here to compete just like everybody else.' I don't train to lose," said Bromell, who won the 100 at the trials last year but failed to reach the final in Tokyo. "So when people complain and things like, 'Is he going to show up in a big race?' This year I'm worried only about myself. I don't care what the naysayers say."
Jamaican Shelly-Ann Fraser-Pryce won the 200 in 22.41.
"I'm feeling good," she said. "A win is always good. In terms of execution, I'm not sure I executed the way I wanted."
In the Bowerman Mile, the Pre's signature event, Norwegian Jakob Ingebrigtsen won in 3:49.76. Last year the Olympic gold medalist in the 1,500 ran the Bowerman in 3:47.24, the fastest time on American soil.
In the Pre's other events, Samuel Tanner won the 1,500 in 3:34.37, and Brazilian Alison Dos Santos, the bronze medalist in Tokyo, won the men's 400 hurdles in 47.23, the leading time in the world this season.
Ethiopia's Berihu Aregawi built a big lead in the 5,000 and cruised to victory in a meet record 12:50.05, breaking Mo Farah's record by 16 seconds. Two-time Olympic gold medalist and Oregon native Ryan Crouser won the shot put with a mark of 75-6¼.
England's Keely Hodgkinson won the 800 in 1:57.72 and Kenya's Faith Kipyegon beat her own meet record in the 1,500 in 3:52.59. Fellow Kenyan Norah Jeruto won the steeplechase in 8:57.97.
The Prefontaine Classic, named after the late Steve Prefontaine, is the third and only U.S. stop on the Diamond League. Hayward Field, on the University of Oregon campus, also will host the U.S. championships in late June before the world championships in July.
