Britany Anderson, the 2018 World U20 100m hurdles silver medallist, ran a personal best 12.71 in the 100m hurdles at the Motonet Joensuu Grand Prix in Finland on Wednesday.

Chanel Brissett leads the world U20 lists with 12.75 – the second fastest time in history at U20 level – but the 18-year-old still missed out on a place on the US team for Tampere.
