Bouwahjgie Nkrumie smashed the Jamaican national junior record to secure a silver medal in the Men’s 100m at the World Under-20 Athletics Championships in Cali, Colombia on Tuesday.

Nkrumie, who equaled the previous national junior record by running 10.11 in the semi-finals earlier, sped to a spectacular 10.02 for silver behind Botswanan sensation Letsile Tebogo, who ran 9.91 to break his own world junior record of 9.94 set at the World Championships in Eugene in July.

South Africa’s Benjamin Richardson ran 10.12 for bronze.

Jamaica’s quartet of Jasauna Dennis, Abigail Campbell, Malachi Johnson and Alliah Baker ran 3:19.98 for bronze in the Mixed 4x400m relay final behind the USA (3:17.69) and India (3:17.76).

In the field, Cuba’s Alejandro Parada jumped 7.91m for silver in the Men’s long jump. France’s Erwin Konate defended his title from last year with a world junior leading 8.08m while Brazil’s Gabriel Luiz Boza jumped 7.90m for third.

Jamaica’s Kobe Lawrence threw a personal best 20.58m for silver in the Men’s shot-put won by the USA’s Tarik O’Hagan (20.73m). Germany’s Tizian Lauria was third with 20.55m.
