Jamaica failed to add to its medal haul on Thursday's fourth day of the World Under-20 Championships at the Pascual Guerrero Olympic Stadium in Cali, Colombia, despite fielding athletes in three finals.
Bryan Level was sixth in the men's 200m in 20.72 seconds as red-hot favourite Letsile Tebogo of Botswana was upset, beaten by Israel's Blessing Akawasi Afrifah in a close finish.
Tebogo had broken the World Under-20 100m record two days earlier and had set a championship record in the 200m in the first round, but was caught on the line by the Israeli, both timed in 19.96 seconds, a new championships record.
The two 400m finals also failed to produce a medal as Dejeanae Oakley just missed the medals in the women's final, finishing fifth in 52.31 seconds, while Shaemar Uter was seventh in the men's race in 46.36 seconds as Delano Kennedy was disqualified after he false started.
Today, Kobe Lawrence, the silver medallist in the men's shot put, will start his quest for a second medal when he and Christopher Young take part in the men's discus throw prelims.
Machaeda Linton will seek a place in the finals of the women's triple jump event while there will be qualification for both men's and women's 4x400m relays.
Also, Brandon Pottinger will contest the men's high jump final.
On Thursday, Alexis James and Kerrica Hill both advanced to today's semis-finals of the 100m hurdles after both winning their first-round heats with impressive runs.
James ran a personal best 13.04 seconds (0.1m/s) to lead the qualifying while Hill, who has run a sub-13.00 seconds time this year, clocked 13.30 (0.6m/s) for the second best times.
Jamaica's medal prospects in the women's 200m appears to be good with Brianna Lyston leading the qualifiers for the finals with 22.83 seconds (0.2m/s) with Alana Reid also through with a personal best 23.16 seconds (-0.2m/s).
Despite appearing to be limping, world leader Jaydon Hibbert needed just two tries to book his place in the men's triple jump final with a mark of 16.37m (-0.3m/s) after fouling his first effort.
A second Jamaican, Royan Walters, also advanced with a jump of 15.29m and will be the 13th athlete that will contest the final.
J'Voughnn Blake advanced to the semi-finals of the men's 800m on time, after he ran 1:48.97 seconds for fourth place in his heat.
Adrian Nethersole was fifth in his first-round heat with 1:53.91 seconds and failed to make progress.
Both 4x100m relay teams also advanced, the girls team of Serena Cole, Tina Clayton, Alexis James and Tia Clayton ran 43.28 seconds to lead the qualifiers while the men's team of Bouwahjgie Nkrumie, Adrian Kerr, Mark Anthony Daley and David Lynch ran 39.24 seconds for second behind Japan in their first-round heat.
