Athletes are aiming for top-three finishes in Eugene, Ore., to earn spots on the U.S. team for the World Championships in Beijing’s Bird’s Nest from Aug. 22-30.
Felix already qualified for the U.S. team in her trademark event, the 200m, as the reigning Diamond League champion. If she makes the U.S. team in the 400m, she will pick either the 200m or the 400m to run at Worlds.
Merritt is already qualified for Worlds as the reigning World 400m champion.
Other events Saturday include the 100m hurdles semifinals and finals. The field is perhaps the deepest of any event at the U.S. Championships with 2008 Olympic champion Dawn Harper-Nelson, 2013 World champion Brianna Rollins, Summer and Winter Olympian Lolo Jones and the two fastest women in the world this year, Sharika Nelvis and Jasmin Stowers. Rollins has an automatic spot on the Worlds team and will be joined by the top three finishers in the final.
The men’s 400m hurdles and 1500m and women’s long jump and 3000m steeplechase finals are also Saturday.
