Trayvon Bromell and Elaine Thompson-Herah grabbed 100m Diamond League victories Saturday in Eugene, where eight world-leading performances highlighted the action at Hayward Field.
America's Bromell, the fastest man in the world last year, bounced back from a false start disqualification in Birmingham last weekend to win a star-studded men's 100m in 9.93sec.
Jamaica's Thompson-Herah, who won back-to-back Olympic 100m-200m doubles in 2016 and last year, captured the women's 100m in 10.79.
Neither was a world best for 2022, but Thompson-Herah said she was just pleased to hit the line first and healthy on a rainy day in Eugene at the same venue that will host the World Championships on July 15-24.
"I'm excited I crossed the line healthy," Thompson-Herah said. "I don't care about the time. The rain was falling. It was a little cold.
"It shows I'm on a great path," added the Jamaican star, who pulled out of the Birmingham Diamond League meeting with a shoulder injury, testing herself in a lower-level meeting in Kingston last Saturday instead.
"I'm getting into shape," added the Jamaican, who said on Friday that her training had also been disrupted by a nagging Achilles injury. "I'm getting where I need to be."
Thompson-Herah made a smooth start on the damp track and took control at the 50m mark. Rising US star Sha'Carri Richardson won a close battle for second place ahead of Jamaica's Shericka Jackson, both credited with a time of 10.92.
Richardson, 22, shot to prominence last season at the US Olympic trials with a wind-aided 10.64 in the final. But she missed the Tokyo Games after a positive test for marijuana.
Shelly-Ann Fraser-Pryce made it a women's sprint double for Jamaica with a victory in the 200m in 22.41.
Bromell, who clocked a wind-aided 9.75 in Florida earlier this month, said his race left plenty of room for improvement as he looks toward the US World Championship trials in Eugene next month and the Worlds themselves.
"I was happy to come out with a win, but I felt like there was a lot of technical stuff I messed up on," he said. "I'm pretty sure I'm already getting messages from my coach."
