Noah Lyles, Sha'Carri Richardson anchor U.S. sweep of 4x100 relays - ESPN

BUDAPEST, Hungary — Now that they've got the baton thing down, the American sprinters can start brushing up on celebrations.

Noah Lyles and Sha'Carri Richardson anchored their 4x100 teams to victories Saturday, giving the U.S. its first sweep of the short relays at world championships since 2007 and a boost of confidence heading into next year's Olympics.

Lyles finished 3 for 3 at these championships — with wins in the 100, the 200 and the 4x100. He lifted three fingers and shouted «Three!» as he crossed the line to remind the world of what he'd done, which was to become the first man to complete that triple at worlds since Usain Bolt in 2015.

Richardson's celebration was a little different. With the men on the track watching and Richardson still putting on the brakes after she crossed the line, an over-the-moon Christian Coleman came out to celebrate with a hug… or a high-five… or something. They collided, spun around and went tumbling to the ground.

But Richardson popped right back up. No damage was done, and it will go down as one of many sweet memories on a night that was full of them.

«I didn't know she was going to jump like that. I guess I was supposed to catch her. But I don't know. It's all good,» said Coleman, who, along with Lyles, was on the last men's team to win the relay, at world championships in 2019.

It didn't have to be perfect, but maybe that was the point in a race where the Americans had the deepest, fastest lineups. The final exchange in the men's race, between Brandon Carnes and Lyles, ended with Carnes using two hands to shove the baton into the American champion's hands as he accelerated.

Lyles got the baton in time and kept going.

He started the anchor leg with a one-step lead on a Jamaican —
