Jamaica’s shot putter Shaiquan Dunn and the mixed 4x400m relay quartet both failed to get the country on the medal board at the World Under-20 Championships despite credible efforts in their respective finals in Lima, Peru, on Tuesday.

With both finalists on the cards, expectations were high that Jamaica would bring the curtains down on the opening day of the five-day championships with at least one medal, but it was not to be.

The quartet of Demarco Bennett, Shanniqua Williams, Marcinho Rose, and Alliah Baker entered the final with the fastest time, but struggled to keep pace with the early front runners and had to settle for fourth at the end.

They clocked a season’s best 3:22.74, behind the Australians, who won in a national record of 3:19.27. Poland (3:20.44) and China (3:21.27) were second and third.

Meanwhile, Dunn, contesting the shot put final, took his time to get going and, as such, was unable to get anywhere close to his personal best of 20.01. He placed ninth as he failed to register a mark on his first attempt, but later hit 18.92m on his third round effort and just failed to squeeze into the top eight to secure three additional throws.

Cuba’s Emmanuel Ramirez was 10^th with a best throw of 18.42.
