The boys' 200m final was something of a repeat of the 100m, with the same two South African athletes fighting it out for the lead.
The order, however, was reversed this time, as Retshidisitswe Mlenga powered past Tshenolo Lemao to take the win in 21.03. Lemao was not far behind with 21.12, while Luis Brandner took another sprint medal for Germany, taking third place with 21.23.
Cuba’s Marisleisys Duarthe, holder of the world U18 best, produced the expected dominant performance in the girls' javelin. After starting off with 57.83m and 57.90m to take a clear lead, she went much farther still with 62.92m in the third round, a distance which no U18 athlete apart from herself has ever bettered with the 500g implement.
Well behind the winner, there was a fierce battle for the minor medals. Dai Qianqian of China was in third for most of the competition, first with 53.55m from round three, then improving to 54.96m in round five, but a final throw of 57.01m by her compatriot Cai Qing relegated her to bronze. Julia Ulbricht of Germany finished just short of a medal with her final-round effort of 54.77m.
Gong Luying won gold for China in the girls' long jump with a consistent series of jumps, topped by 6.37m in the fourth round.
The other medals were decided even later in the competition. Lea-Sophie Klik came through for Germany with a wind-assisted 6.30m in round five to take silver. France's Diane Mouillac had a major improvement on her final jump and the 6.28m she achieved proved just enough to steal the bronze away from Latvia's Kitija Paula Melnbarde by virtue of a longer second-best jump in the competition.
Swirling wind made it difficult for the pole vaulters to reach top heights. There was a victory for the favourite, Matthias Orban of France, the only one to clear 5.00m. He did it on his third attempt, after already being in the lead from Christos Tamanis of Cyprus, the only other athlete left at that height.
Tamanis took the silver with 4.85m, while of the two athletes who ended the competition with 4.70m, Ilya Kravchenko of Ukraine prevailed on countback to take the bronze from the German Daniel Breinl.
