Flame-haired Sha'Carri Richardson has set up a headline sprint showdown with Jamaican superstar Shelly-Ann Fraser-Pryce in Tokyo after a dominant display in the women's 100m at the US Olympic trials.
Richardson, 21, flashed home in her semi in a wind-assisted 10.64 seconds in Eugene on Saturday night and then backed up to win the final in 10.86.
An over-the-limit tailwind prevented the 10.64 from becoming official and leaving Richardson only one-hundredth of a second behind Fraser-Pryce's top time of 2021.
But the season is far from over.
The world record of 10.49 was set by Florence Griffith Joyner in 1988.
"She carries such a firecracker," said Richardson's training partner, Justin Gatlin.
"She's capable of running 10.6. I've seen her at practice, and she's capable of running 10.5, actually. She can definitely shock the world."
The only question surrounding Richardson this week was what coloured hair she'd bring to the starting line.
She went with orange.
Style is part of her game. She says she's proud to sport long nails, too, just like one of her idols - Griffith Joyner.
While Richardson's blazing speed made her close to a sure thing in the women's 100m, the men's sprint is nowhere near as settled.
The race for the three Olympic spots in their crowded 100m could be the best battle of the meet.
All the big names made it through, including Fred Kerley, whose main distance is the 400m.
Now Gatlin (the former Olympic and world champion), Trayvon Bromell (this year's world leader at 9.77), and star-in-the-making Noah Lyles, whose chances are more secure in the 200m, have something to worry about as they approach Sunday's finals.
The packed field does not include the reigning world champion, Christian Coleman, who is banned this year because of a doping violation that stemmed from a series of missed tests and a failed appeal to have the suspension overturned.
The semis and final of the men's 100m are on Sunday (Monday AEST).
