Lyles seals world double as USA men win sprint relay

Noah Lyles won his second gold of the Tokyo world championships on Sunday after anchoring the USA team to victory in the men's 4x100 metres relay.

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.

USA quartets have so often been plagued by baton handover problems in recent championships that it was almost a rarity to see them perform so smoothly.

"We all know we are the fastest. We just had to get the baton from start to finish," said Lyles.

"When Christian passed the baton I knew it was a done deal. I saw the lead we had and it was a kind of a relief as everybody did such a great job.

"I just had to finish the race. They made it easy for me. I could have not ask for a better relay."

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.
