Most other top runners would certainly have set a world best in a good time, but that doesn't apply to Jackoson, who won the World Championships in the 200 meters last year in a whopping 21.45, only eleven hundredths off Florence Griffith-Joyner's world record from 1988.
"I'm not surprised by the time, in fact I'm disappointed because I spoke to one of my teammates and said I was going to run in 10.79. But despite everything, I'm grateful," Jackson told the Jamaica Observer after the race that was in a narrow, narrow headwind, -0.1 meters per second.
Free place at the World Championships in Budapest
At the World Championships in Eugene last year, she finished second in the 100 metres, with a personal best of 10.71.
As the defending champion, she has a free place in the 200 meters at this summer's World Championships in Budapest, the year after Eugene due to the pandemic, and of course wants to take a place in the 4x100 meter team. There are strict rules in Jamaica and she must be in the top three to get a place.
"That's going to be my main focus in qualifying," Jackson said of the competition, which is also a national championship, the same setup as in the United States.
18-year-old shocked Florida world champion
In Florida, 18-year-old Issam Asinga shocked by winning the 100 meters in 9.83 in too strong a tailwind (2.6 meters per second against the approved 2.0) but perhaps more remarkable than the time was that he beat Noah Lyles, world champion in the 200 meters, clearly. Lyles was second at 9.92.
Converted to approved wind, Asinga's time was worth 9.93.
"You haven't seen anything yet," Asinga, born December 29, 2004, confidently wrote on Instagram.
There were simple circumstances during the race where you started in front of a barn and the small crowd sat in a grass slope because there were no grandstands.
