At the beginning of the season, there has been talk of Shelly-Ann Fraser-Pryce and Elaine Thompson-Herah and their chances of beating Florence Griffith-Joyner's world record of 10.49 from 1988. Instead, it was Jackson, who went down from 400 meters, who won the race at season-best 10.77, making her second in the annual best list.

Second in the race was 22-year-old talent Kemba Nelson who set a personal record with 10.88 while Thompson-Herah had to settle for third place at 10.89 at the National Stadium in Kingston.

Fraser-Pryce crossed after 10.70 in the attempt

Fraser-Pryce ran at 10.70 in the attempt on Friday night but then stroked.

She already has a wildcard to the World Cup in Oregon July 15-24 as the reigning world champion, otherwise Jamaica has the same tough requirements as the USA and the first three in each branch automatically get a place in the championship.

There was a problem with the starter's equipment and there was a 15 minute delay.

- It was a real improvement on the annual best (from 10.92) so I have nothing to complain about.

Now I look forward to trying to win my first World Championship title in the 100 meters in Oregon, says 27-year-old Jackson who has two individual World Cup bronzes in the 400 meters.

Yohan Blake made a leap back in time and won the men's race of 9.86 according to Reuters, his best time in ten years.

The 32-year-old won his fifth national title and dedicated the victory to his father who suffered a stroke a few days ago.

- I wanted to give him this victory.

It has been so anxious all week and I needed to be strong to cope with this, says Blake.
