Dawn Harper-Nelson beat the World champion in the 100m hurdles to win the U.S. Championship and celebrated with a cartwheel.
Harper-Nelson, the 2008 Olympic champion, clocked 12.55 seconds in the final in Sacramento, Calif. Queen Harrison was second in 12.56, followed by Lolo Jones in 12.65. World champion Brianna Rollins, who also owns the fastest time in the world this year, was fifth in 12.81.
“I made a little mistake in the middle [of the race], and I was like, ‘Oh, Lord, don’t let it go,'” Harper-Nelson told Lewis Johnson on NBC. “I knew it was going to be a great race. Fierce ladies.”
In the women’s 400m final, Olympic champion Sanya Richards-Ross couldn’t run down Francena McCorory. McCorory, the World Indoor champion, ran a personal best 49.48 seconds. That’s the fastest 400m by an American woman since Richards-Ross won the 2012 Olympic Trials in 49.28.
“I just wanted to get out, execute my race and finish strong,” said McCorory, gasping for breaths. “I’m just happy for the win.”
Richards-Ross went her fastest time of 2014 by .37 of a second, one day after chopping 1.16 seconds off her best time this year. She’s coming back from toe injuries that sidelined her most of the last season.
“What keeps me going now is my legacy,” said Richards-Ross, 29, a five-time Olympic medalist. “I do want to be a two-time [individual] Olympic champion, so I’m working hard to get back to Rio.”
The U.S. Championships finish Sunday with finals including the 200m, men’s 110m hurdles and women’s 1500m.
