The American quartet of Christian Coleman, Kenny Bednarek, Courtney Lindsey and Lyles clocked 37.29sec.

Canada bagged silver in 37.55sec, with the Netherlands taking bronze in 37.81.

Lyles only won bronze in the 100m last weekend but then matched Jamaican legend Usain Bolt's record of four consecutive world 200m titles after he convincingly won that event on Friday.

The relay victory handed Lyles an eighth world gold as part of his 10-medal haul.

He is also the reigning Olympic 100m champion and has back-to-back 200m bronzes from the Paris and Tokyo Games.

JEFFERSON-WOODEN COMPLETES WORLD SPRINT TREBLE WITH US RELAY WIN

Melissa Jefferson-Wooden became only the second woman to win a world sprint treble after leading the United States to 4x100 metres relay gold on Sunday, with Jamaica's Shelly-Ann Fraser-Pryce taking silver in her final race.

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 teammate 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.
