Vijender Kumar assured India of yet another medal when he entered the semi-finals of the middleweight (75kg) category on Wednesday.
Vijender defeated Ecuador's Carlos Gongora 9-4 at the Workers' Gymnasium.
In the Olympic boxing event even the losing semifinalists get a bronze medal.
Vijender maintained a dour defence which Gongora simply could not breach.
Vijender looked indefatigable and his nimble footwork stood him in good stead as the Indian tired out his opponent and connected most of his blows to run away with the game.
