Britain's 200m world champion Dina Asher-Smith saw off the challenge of US sprint star Sha'Carri Richardson to win the 100m at Sunday's opening Diamond League meet in Gateshead.
The 25-year old started strongly in wet conditions in the northeast of England and crossed the line to take gold in a time of 11.35 seconds, with Richardson second in 11.44.
The Ivory Coast's Marie-Josee Ta Lou was third in 11.48.
Richardson is fresh from clocking 10.72sec at the Miramar Invitational last month, making her the sixth-fastest female sprinter ever.
The field for the final also included Jamaican 100m world champion Shelly-Ann Fraser-Pryce, who finished fourth, and Blessing Okagbare of Nigeria.
Gateshead stepped in to host the meet after Rabat pulled out because of Covid-19 restrictions in Morocco.
There are only six Diamond League meetings after Gateshead before the Olympics in Japan.
