Letsile Tebogo and Tina Clayton claimed the 100 metres men's and women's junior world titles respectively on day two of the World Athletics Under-20 (U20) Championships in Nairobi.

Botswana's Tebogo was the strong favourite entering the final after running an U20 national record of 10.11sec in the semi-finals. 

He followed that up with 10.19 in the final, with Benjamin Richardson of South Africa running 10.28 and Shainer Rengifo Montoya of Cuba running 10.32 to complete the podium. 

Jamaican Clayton also won the women's 100m comfortably, though was not as strong a favourite before the race. 

Clayton edged out Namibia's Beatrice Masilingi by 0.01 in their respective semi-final times. 

Masilingi, though, tied up in the final and Clayton eased to victory, recording a personal best (PB) 11.09.
