Lyles, McLaughlin-Levrone lead US Olympic team after impressive trials

Sydney McLaughlin-Levrone's world record run in the 400 hurdles wrapped up the U.S. Olympic trials in style on Sunday in Eugene, Oregon, where Noah Lyles showed he will have a real shot at taking the sprint double in Paris.

"I definitely thrive off pressure. I thrive off big moments," he told reporters. "The bigger the moment, the faster I run."

Sha'Carri Richardson dominated the women's 100 with the season's fastest time 10.71, three years after a positive test for cannabis shattered her dream of competing at the Tokyo Games.

The world champion and U.S. fan favourite left Hayward Field with a smile despite coming up short in the 200, where she finished fourth.

In the 200, Tokyo bronze medallist Gabby Thomas had the world lead in the semi-finals and the second-fastest time of the year in the final, underlining her claim as the top Paris contender.

"In our sport, especially with the women, there are always going to be some really good contenders on the line and I think I've proven I can line up with anyone and come out on top," said Thomas.

Olympic men's 400 hurdles silver medallist Rai Benjamin cruised to victory in 46.46, the fifth-fastest performance of
