![Ashley Landis FILE - Sydney McLaughlin-Levrone waves to the crowd after winning the women's 400 meters during the U.S. track and field championships in Eugene, Ore., July 8, 2023. Sydney McLaughlin-Levrone plans on defending her title in the 400-meter hurdles at the Olympics, and has scratched from the 200 and 400-meter flat races that she had originally signed up for. The world-record holder had been entered in all three races for this month's U.S. Olympic trials, but as of Tuesday, June 18, 2024, she was listed as a “scratch” in the 200 and 400.
