Sophie Hitchon became the first British woman to win an Olympic hammer medal by taking bronze, as Pole Anita Wlodarczyk set a new world record to claim gold.
Hitchon threw a new British record of 74.54m on her final attempt to climb from fifth to third.
World champion Wlodarczyk, 31, threw 82.29m to break her own world record of 81.08m, while China's Zhang Wenxiu took the silver medal with 76.75m.
"I am over the moon," said Hitchon, 25. "I can't believe it."
