Delano Kennedy walks off the track after being disqualified due to a false start in the men's 400m final.
Jamaica failed to add to its tally of medals on day four of the World Athletics Under 20 Championships.
Despite having four competitors in three of the finals, none was able to make it on the podium.
Hopes were high that five medals for Jamaica would have been increased after the fourth day.
Dejanea Oakley made it to the women's 400 meters final but found the pace difficult to match and finished fifth in 52.31 seconds as Yemi Mary John of Great Britain won gold in a personal best of 51.50 seconds.
Jamaica had two competitors in the men's equivalent but lost one opportunity at the start as Delano Kennedy left the blocks before the gun.
Shaemar Uter stuck around but could not get himself in medal position as he could only manage sixth in a time of 46.36 seconds.
South Africa's Lythe Pillay was the winner in a personal best 45.28 seconds.
It was then left down to the last hope of the day, Bryan Levell in the men's 200 meters.
But the day ended on a whimper as Levell, who got a good start, faded in the straight to finish sixth in 20.72 seconds.
Blessing Akawasi Afrifah was the surprise winner as he pipped the overwhelming favourite Letsile Tebogo in a championship record time of 19.96 seconds.
Tebogo, the 100 meters champion and world junior record holder for that event, was also credited with a similar time.
Progress
Jamaica will have two representatives in the women's 200 meters final on Friday as Brianna Lyston took her semifinal in a time of 22.83 seconds.
She will be joined by her Hydel schoolmate Alana Reid, who was second in semifinal three after clocking a personal best 23.16 seconds.
The sprint relay teams have also made progress to the final. The female team of Serena Cole, Tina Clayton, Alexis James and Tia Clayton won their heats in 43.28 seconds.
The men's team of Bouwahjgie Nkrumie, Adrian Kerr, Mark-Anthony Daley and David Lynch clocked 39.24 seconds to place second in their event to make progress.
Roshawn Clarke will line up in the men's 400 meter hurdles final after scaling the obstacles in a personal best 49.35 seconds.
Antonio Forbes was not as fortunate, as he ended down the track for sixth in his semifinal in 51.42.
The triple jump will see two Jamaicans lining up in the final as Jaydon Hibbert hopped, skipped and jumped to 16.37 meters with the best mark going into the decider.
He will have company in Royan Walters, who posted 15.29 meters to book his spot.
Jamaica made statement runs in the women's 100 meter hurdles heats as Kerrica Hill posted 13.30 seconds in her heat to take the top spot.
