The two-time Olympic champion Shelly-Ann Fraser-Pryce stormed to a 100m victory at the Jamaican National Championships in a blazing time of 10.71 seconds (wind +1.0 m/s) on Friday night.
The second-fastest woman in history, Fraser-Pryce broke away from the field at 50m to win the 100m final and to book her a ticket to her fourth straight Olympic Games in Tokyo.
"It's amazing and I think all credit goes to my coach (Reynaldo Walcott). You know he's such a firm believer in what I can do and what I'm capable of," she said.
"After the 10.63 (June 5) it was rough! My hamstrings were just giving problems after that run, but I said champions show up no matter what, you always show up and you just have to make sure that when you get to the line you deliver," Fraser-Pryce added.
Rio Olympic 400m bronze medallist Shericka Jackson, who clocked 10.77 in the semi-finals, took second place in 10.82secs, just 0.02 seconds ahead of reigning double sprint champion Olympic Champion Elaine Thompson-Herah.
The World Junior U20 100m and 200m champion Briana Williams clocked 11.01 to take 4th place.
The men's 100m final won Tyquendo Tracey who clocked 10.00s (wind +0.6m/s). Yohan Blake, the 2011 World champion, took second place with 10.01, while 20-year-old Oblique Seville clocked a new personal best time of 10.04 for third place.
The top three men and women will represent Jamaica in the Tokyo Olympics.
