GUANGZHOU, China (AFP) — Success Eduan lived up to her name by anchoring Great Britain to a thrilling victory in the women’s 4x100-meter run at the World Athletics Relays in Guangzhou on Sunday while Akani Simbine led South Africa to victory in the men's event.

Eduan produced a thrilling final leg to outpace Jamaica's Shericka Jackson and Twanisha Terry of the United States for gold along with teammates Nia Wedderburn-Goodison, Amy Hunt and Bianca Williams.

"I did not think too much of (the) others, I just knew that if I gave all myself in, it would come out all right," Eduan said.

"I have a mentality of a winner, I don't care if Shericka or Shelly-Ann (Fraser-Pryce), with respect to them, are running. I am going to give my all and I'm going to pass them and I'm going to win. And we did that!"

Spain snatched a shock silver in 42.28 seconds with the Jamaican quartet also featuring multi-medaled Fraser-Pryce taking bronze (42.33 seconds), just five-hundredths ahead of the US team.

"We came out, took the chance, got a medal, qualified for the world championship in Tokyo," said Fraser-Pryce, whose first Olympic gold medal was at the 2008 Beijing Games.

"All in all we are very pleased. We are grateful for getting a bronze medal, and we will leave the fight for another day."

South Africa had in-form Simbine, winner of the two opening Diamond League 100m races this season, to thank for an electric anchor leg as he powered past Brandon Hicklin for gold in the men's 4x100m relay.

The team also featuring Bayanda Walaza, Sinesipho Dambile and Bradley Nkoana clocked a world leading time of 37.61 seconds.

The United States took silver in 37.66 seconds, with Canada, featuring the same quartet who won gold in last year's Paris Olympics, claiming bronze.

"Once I got the baton I saw that US (were) in front of us, I just said to myself 'I need to catch the guy in front'," Simbine said.

"I knew I could do it, and I just chased him. I feed from chasing, I feed from being able to chase. So it's really great to be able to be in that position and get through it and get to the line first."
