Australia's Jeffrey Horn has triumphed over Zambia's Gilbert Choombe in the Olympic light welterweight division.
Choombe looked way out of his depth as Horn surged forward from the first bell, targeting the body with a string of energy-sapping blows.
Horn had opened up a 10-3 lead at the end of two rounds, thanks to constant pressure and a barrage of shots.
The Australian applied some different tactics in the final stanza, moving in and out quickly, twice delivering the right sharply.
The Zambian found himself suitably overwhelmed from start to finish and fell to a 19-5 defeat.
