The event was won by Sweden’s Daniel Stahl with a championship record 71.46m while Slovenia’s Kristjan Ceh threw 70.02m for second and Lithuania’s Mykolas Alekna threw 68.85m for third.
It was an exciting end to the competition as Ceh took the lead with his final round effort before Stahl produced the championship record throw with the very last throw of the competition.
Traves Smikle finished 11th with a best throw of 61.90m.
Jackson, who made her season debut in the 100m in Kingston on May 4 after a late start to her season, was not at her sharpest in Rabat but good enough to keep the field at bay as she sprinted to victory in 22.82 seconds while running into a headwind of -1.0m/s.
Maboundou Kone of the Ivory Coast was a close second in 22.96 with Helene Parisot of England in 23.02.
Earlier, Clayton was more impressive. Coming off an encouraging victory at the Jamaica Athletic Invitational on May 11 when she ran a world-leading 53.72, Clayton once again dominated the first 300m but was closed down by compatriot Shian Salmon along the home stretch. Still, she managed to hold on to win in 53.98. Salmon ran an enterprising race for second place clocking 54.27.
Anna Ryzhykova ran a commendable 55.09 for third place.
While fortune smiled on Jamaica’s women, the men were not as fortunate as Rohan Watson was edged out of a podium finish in the men’s 100m dash. The reigning Jamaican champion finished fifth in 10.26. He was credited with the same time as fourth-placed finisher Brandon Hicklin of the USA and was 0.01 behind Great Britain’s Jeremiah Azu, who took third in 10.25.
There was no doubt about the winner Emmanuel Eseme of Cameroon who crossed first in 10.11 with Canada’s Andre Degrasse finishing in second place in 10.19.
Yohan Blake ran a season’s best 10.41 while being eighth.
In the men’s discus, Travis Smikle once again exceeded 66m but missed out on a podium position. He finished fourth with his best throw of 66.03m. However, he was no match for winner Mykolas Anelka. The newly minted world record holder produced an impressive throw of 70.70m to win the contest.
Matthew Denny of Australia finished in the runner-up position with his throw of 67.74m. Olympic and World Champion Daniel Stahl threw 67.49m for third place.
Fedrick Dacres threw 65.05 for sixth place.
