World 800m champion Caster Semenya secured her third gold medal with a convincing victory in her specialist event on day two of the SA Student Athletics Championships in Stellenbosch on Saturday.
Semenya, who won the 400m and 1 500m titles on Friday, dragged the field through the first lap in the women's 800m final with Juanee Cilliers and Mandi Brandt fighting to stay in touch.
The 20-year-old pulled clear, however, to win by more than two seconds in 2:02.52.
Brandt secured the silver medal in 2:04.65 and Cilliers held on for the bronze in 2:06.38.
Semenya was set to compete in the women's 4x400m relay later in the afternoon in a bid for her fourth gold medal of the championships.
