This could be one of the biggest upsets for the U.S. at the Rio Olympics.
On Monday night, the women sprinters raced in the 400 meters. At the very end, Shaunae Miller of the Bahamas dove across the finish line, nabbing the gold medal from the second place winner, Team USA's Allyson Felix.
Miller started out strong in the race, but she and Felix were neck and neck in the final moments before Miller dove for gold.
Because Miller's torso crossed the finish line first, she earned a gold medal, and Felix took home the silver.

"'I've never done it before," Miller said. "I have some cuts and bruises, a few burns... it hurts."
She said that when she hit the ground, she had no idea she actually won the gold.
"What was in my mind was I had to get a gold medal. The next thing I was on the ground. It's an amazing feeling," she said.
Fans of the Olympics took to social media with their opinions on Miller's controversial win.
So all of this leads to a question: Was this a dirty way to win?
