In one of the greatest upsets in boxing history, Jeff Horn stunned Manny Pacquiao with unanimous points to claim the WBO welterweight world title in Brisbane.

Before the bout, few gave any chance to Horn, a school teacher of beating the celebrated boxer. The match spanning 12 rounds saw the Filipino landing more punches but the judges voted in favour of Horn.

The 29-year-old Horn was adjudged winner over the southpaw Pacquio by scores of 117-111, 115-113 and 115-113.

Horn punched well in the earlier rounds and forced Pacquiao to take treatment during the sixth and seventh rounds for a cut.
