Olympic sprint champion Elaine Thompson dominated the women’s 100 metres at the Diamond League meet in Rome to beat Kent’s Dina Asher-Smith by a narrow margin.

Jamaican Thompson powered on late to pull clear of her rivals clocking a world leading 10.89sec at the Olympic Stadium.

Asher-Smith, from Orpington, crossed second in 10.94sec with American Aleia Hobbs, winner in Shanghai, third in 11.12sec.

Thompson, the Olympic champion in the 100m and 200m, had been stunned by Asher-Smith over the same distance in Stockholm last week with the Briton also winning in Doha in May.

But this time it was 23-year-old Asher-Smith who was taken by surprise.

“The race wasn’t what I expected, although I had a really fast start which is good,” said triple European champion Asher-Smith, who was making her debut this season over 100m.

“Opening the season with sub 11 seconds isn’t bad at all, especially when I’m still feeling a little rusty,” she said.

“I’m going to continue to listen to my coach and train hard so I perform well at the world championships later this year,” added the Briton as she looks towards worlds in Doha in September.
