Sydney McLaughlin has broken the world record for the women's 400m hurdles at the US Olympic Trials ahead of Tokyo.
The 21-year-old was a silver medallist at the 2019 World Championships in Doha where Dalilah Muhammad won gold and set the previous record of 52.16 seconds.
But in Eugene, Oregon, McLaughlin saw off Muhammad and broke her old record, setting a time of 51.9.
Anna Cockrell finished third, with all three women booking their places at the Games.

"This season, working with my new coach and just my new support system, it's truly just faith and trusting the process and I couldn't ask for anything more," said McLaughlin, who has the same coach as six-time Olympic gold medallist Allyson Felix in Bob Kersee.

In the men's 200m final, 17-year-old spring sensation Erriyon Knighton qualified for the Olympics by running a new under-18 world record time of 19:84sec.
Noah Lyles qualified in first place with the fastest time of the year, 19.74, with Kenny Bednarek making up the trio as he split the other two with personal best time of 19.78.
