American Marconi Wireless News - Jefferson-Wooden completes world sprint treble with US relay win

Jefferson-Wooden matched Fraser-Pryce's achievement from the 2013 world championships in Moscow by adding to the 100m and 200m titles that she bagged in Tokyo.

She led off the race in driving rain before handing off to her team-mate Twanisha Terry before Kayla White ran the bend and Sha'Carri Richardson took the baton across the line in a time of 41.75sec.

Jamaica were second in 41.79sec, followed by Germany in 41.87sec.

Fraser-Pryce was competing in her final race before bringing the curtain down on an incredible 17-year career.

She went into the race with three Olympic gold medals and 10 world titles, and a total of 25 Olympic and world medals to her name.

She made sure she signed off with one more, leading off a Jamaican team that also included sisters Tia Clayton and Tina Clayton and Jonielle Smith.

But Fraser-Pryce was unable to snag one last gold ahead of the Americans.

Jefferson-Wooden had already become the first woman to win a world sprint double since Fraser-Pryce as she dominated the 100m and 200m finals.

She got the US off to a strong start but Jamaica were ahead until a clumsy baton change between Tia and Tina Clayton lost them valuable time.

The US led heading into the final straight and Richardson held off a furious late charge by Smith to cross the line in first, roaring in delight.
