Shericka Jackson became the fifth fastest woman of all time as she clocked 10.65 seconds to win the 100m at Jamaica’s national championships.
It was the fastest time in the world this year – beating the 10.71 run by Sha’Carri Richardson at the US championships the previous day.
Jackson, who is tied with American Marion Jones for fifth on the all-time list, said she could still improve.
“I think the ending needs a little fixing,” said the 28-year-old.
“I know I’m a strong finisher, but I still need to work on that a bit. I have to go back to the drawing board with coach, but I did a very good job.”
The women’s world record is 10.49 – set by Florence Griffith-Joyner in 1988.
Friday’s victory means Jackson – 200m champion and 100m silver medallist at last year’s World Championships in Oregon – will be heading to the World Championships in Budapest in August.
She will be joined by Shashalee Forbes and Natasha Morrison, who came second and third respectively, while Shelly-Ann Fraser-Pryce also qualifies as defending world champion.
Two-time Olympic champion Elaine Thompson-Herah, however, will not feature after coming fifth following an injury-affected season.
The men’s event was won by Jackson’s training partner Rohan Watson, 21.
He won his first final at any level in 9.91secs – the joint-ninth fastest time of the year and 10th best ever by a Jamaican.
