In 10.77 seconds Shericka Jackson wrote her name in history.
The 400-metre specialist turned sprinter is the fastest woman in Jamaica after claiming the National title in a 100-metre race fraught with controversy and real speed alongside her.
Jackson got the better of a fast-finishing Kemba Nelson, who dipped at the line in a personal best 10.88, and favourite Elaine Thompson Herah, 10.89.
With Shelly-Ann Fraser Pryce out, Thompson Herah was the favourite going into the final even though Jackson had shown a frightening pace in the two earlier rounds.
Even in the semi-final where Thompson Herah, beat Jackson, there seemed so much left in the tank that may be the result should not have been a surprise.
But a long delay at the start seemed to be in the favour of the experienced Thompson Herah because maybe Jackson’s good starts would desert her.
She had one more in the tank.
Getting up slightly behind the fast-starting Briana Williams, who would end fourth in a personal best 10.94, Jackson surged to the front and by 60 metres, the race was over.
Thompson Herah, at this point, was third, but surged past the fading Williams, only to be pipped at the line by Nelson all the way out in lane eight.
