LONDON — In the most jaw-dropping result in a week of upsets at the track and field world championships, the United States grabbed an unlikely 1-2 finish in the women’s steeplechase Friday night at the expense of the Kenyans.

Emma Coburn took the lead for good at the final water jump and kicked for home to finish in a championship record of 9:02.58.

“Oh my goodness, what a race to be part of,” Coburn said. “I never expected to win in that time but I kept pressing. It is pretty amazing to get a championship record.”

American teammate Courtney Frerichs finished second by outkicking defending champion Hyvin Jepkemoi of Kenya in a sprint for silver.

“I would never have believed this could happen,” Frerichs said.

Beatrice Chepkoech of Kenya, the third best performer this year, was running in the lead at the start when she missed the turn for the water jump on the inside of the track and had to go back. She made a strong comeback but faded in the last lap.

Dafne Schippers of the Netherlands restored some normalcy when she proved again she’s the fastest woman over 200 meters. She dipped at the line just ahead of Marie-Josee Ta Lou in another extremely close race to defend her title in 20.05 seconds.

Brittney Reese added a world title to the Olympic gold she won in the same stadium five years ago. The American hadn’t won a major title since 2013, but her jump of 23-01/2 was good enough for her fourth world title.
