Swiss cheers for Kambundji

Ditaji Kambundji of Switzerland held off the world record-holder and reigning Olympic champion to win a surprise gold in the 100m hurdles.

After crossing the finish line, Kambundji stared up at the scoreboard waiting to see where her name would wind up. When she saw she was in first place, her eyes widened and she covered her mouth in shock.

Kambundji finished in a personal-best 12.24 seconds to hold off world record-holder Tobi Amusan of Nigeria by 0.05 seconds. American Grace Stark took bronze while Masai Russell, who won gold at the Paris Olympics last summer, was fourth.

"You could see on my face how happy I was when I realized I won," Kambundji said.
