At the Jamaican championships on Saturday, Shericka Jackson ran a world-leading 10.65 seconds in the 100 meters, making her the joint-fifth fastest woman in history.
This time, Jackson finished in joint fifth place, 0.16 seconds behind the 35-year-old world record held by Florence Griffith-Joyner.
This record additionally saw her outperform American Sha’Carri Richardson, who brought home the US 100-meter championship on Friday, for the fastest womens’ 100-meter time this year.
Meanwhile, the year’s fastest women’s 100-meter time is set by Sha’Carri Richardson.
In Kingston, Jackson, who has won five Olympic medals and is the defending world champion in the 200-meter event, finished comfortably ahead of Shashalee Forbes (10.96 seconds) and Natasha Morrison (10.98 seconds).
“I told them last year that one of my main problems was the start. I think tonight I mastered it … I have to go back to the drawing board with coach (Paul Francis), but tonight I did a very good Job,” Jackson told Reuters after her victory.
“I know I’m a strong finisher, but I still need to work on that a bit because I made a miss-step, so coach and I will continue working on my stride pattern going forward.
“It’s been tough coming down from the 400-meters to the 100-meters since in 2021.”
Elaine Thompson-Herah, the Olympic 100 and 200-meter champion, completed fifth, meaning her cooperation in the 100 meters at next month’s big showdowns in Budapest, Hungary, is in uncertainty.
Because Shelly-Ann Fraser-Pryce is the defending champion, Jamaica will send four women to Budapest for the competition. Same applies for Jackson in the 200 meters after her triumph in Eugene, Oregon, last year.
