Brianna Rollins led an American domination of the 100-meters hurdles on a golden night for the US women at Rio 2016.
Rollins, who finished ahead of teammates Nia Ali and Kristi Castlin in a thrilling final, cruised home in a time of 12.48 seconds.
It was the second gold medal of the night for the US after Tianna Bartoletta triumphed in the long-jump with fellow American Brittney Reese coming second.
The US trio took the medals in a thrilling 100-meter hurdles race.
Rollins, the 2013 world champion, had looked good in qualifying for the final and showed her class in beating her teammates.
"It's a relief," Rollins told reporters.
"There has been such a lot of anticipation. I have younger brothers and as the oldest I like to lead by example - even from far away."
