The Fastest Man in the World wasn't the fastest man in Jamaica on Friday night.
That honour went to Yohan Blake, who jumped out of the blocks fast and finished the 100m final in 9.75 seconds to upset world-record holder Usain Bolt by 0.11 seconds in the Jamaican Olympic trials.
The result will shake up the consensus that Bolt will stroll to the Olympic title in London just as he did in Beijing.
Blake is the reigning world champion but Bolt didn't run that night in South Korea after being disqualified for a false start.
This was their first rematch - their first real race since.
Bolt was considered the favourite, not only because of his world record - 9.58 seconds - but because Blake, his training partner, had never run below 9.84 in his life.
Now he has.
The 9.75 seconds goes down as the best time this year and also breaks the four-year-old National Stadium record; both marks were 9.76 - both held by Bolt.
Blake, the man known as "The Beast", let out a scream when he crossed the line.
Bolt pulled up - no "To the World" pose or anything else to celebrate.
Asafa Powell will join them at the Olympics, after finishing in 9.88.
In the women's 100m, defending Olympic champion Shelly-Ann Fraser-Pryce won in a Jamaican record 10.70 seconds, with Veronica Campbell-Brown in second and Kerron Stewart in third.
Campbell-Brown provided the surprise at last year's trials when she finished fourth in the final and didn't make the 100m field.
She ended up winning the 200 at trials and the Olympics and is very much in line for a double this time, as well.
So are Blake and Bolt.
It was widely believed Blake might provide a better challenge to Bolt in the 200 because he holds the world's second-fastest time at 19.26.
Bolt's record is 19.19. They'll run in heats on Saturday with the final scheduled for Sunday.
But in track's most glamorous event, the 100, it's Blake who heads to London with the win.
