Sha’Carri Richardson made her first Olympic gold-medal moment memorable - giving the sprinters behind her the side-eye, then stomping her foot to the track on her final step across the finish line.

Afterward, she moved aside to watch the U.S. men do what they do best in the 4x100 relay - find a way to lose.

Richardson, who won silver in the 100 last weekend, powered from third to first in the anchor leg to lift the United States to victory Friday, then had a front-row seat to watch the U.S. men extend their streak to 20 years without a medal at the Games.

“I was very comfortable with these ladies,” Richardson said of a foursome that includes her training partners, 100-meter bronze medalist Melissa Jefferson and Twanisha Terry, and 200-meter champion Gabby Thomas.

The men were racing without Noah Lyles, who called it quits for the Olympics after winning the bronze medal in the 200 while fighting COVID. Hard to think that even he could’ve saved them.

This race unraveled on the first exchange, when Christian Coleman crashed into Kenny Bednarek, then actually ran by him as they were awkwardly passing the baton.

By the time Fred Kerley took the stick for the anchor lap, the U.S. was in seventh place. They ended up being disqualified for the illegal pass. Not even Lyles could’ve overcome that.

With the US out, Andre De Grasse put a bright mark on his otherwise disappointing Olympics by anchoring Canada to gold in a time of 37.50 seconds.

It was the first medal in Paris for De Grasse, and the first for the Canadians in the one-lap relay since Donovan Bailey anchored them in 1996. South Africa finished second and Britain third.

The secret?

In the evening’s final race, American Rai Benjamin finally pulled out of the shadow of world-record holder Karsten Warholm, getting his first individual major title by blowing past the defending champion in 46.46 seconds.

Alison dos Santos of Brazil finished third for the second straight Olympics, giving these Games the same three men on the podium as Tokyo.

This race was no repeat of that one - the fastest hurdles race ever - but Benjamin still ran a time that would’ve been a world record 37 months ago, before Warholm took it below 46 seconds.

Looking in on the relays in disgust, but not surprise, was Carl Lewis, a two-time winner in this race who is never shy about calling out what he sees.

In an interview last week with The Associated Press, Lewis suggested experts in the U.S. develop a relay manual and send it to every high school coach in the country.

“The issue has always been politics, has always been drama, has always been deception,” Lewis said. “If they can eliminate those things, there’s no question they have the fastest team in the world.”

Some might blame the latest loss on the impact of the lineup shuffle. Lyles, who ran anchor in the U.S. victory last year at world championships, probably would have done so again at Stade de France.
