Update: The WBO's formal review of the fight's scoring, which featured five independent judges from around the world who watched the fight with the sound off, confirmed the original decision. Three of the five judges awarded it for Horn, one awarded it to Pacquiao and one had it a draw.

Based upon the aggregated results, using a scoring system developed by WBO president Francisco Valcarcel to ascertain which rounds each fighter won using an average scale, it was established that Horn won seven rounds and Pacquiao won five (which was consistent with two of the three official judges on fight night).

Original story

The World Boxing Organization confirmed Thursday that it plans to rescore the Manny Pacquiao vs. Jeff Horn fight due to the controversial nature of the unanimous decision that led to Horn upsetting Pacquiao and winning the welterweight title. Though the WBO has chosen to proceed with the rescoring, it is not expecting to change the result of the match regardless of whomever the process determines won the fight.

"The purpose of this review is to be able to give the fans certainty of who was the winner of the bout, even though we do not have the power to reverse the decision of the judges," WBO president Francisco Valcarcel told the Associated Press.

The fight will be scored round-by-round by five anonymous judges whose results will be tabulated after each round "to ascertain clearly which rounds each fighter won."

The bout was initially scored 117-111, 115-113, 115-113. The former score was the most controversial as, while many believe Pacquiao won outright, a close decision was at least somewhat understandable. Few stand with Horn winning by such a large margin.

Fans wanting a reversed fight result will be disappointed regardless of the outcome of the rescore as that would only change if officiating fraud is somehow proven.

The WBO has chosen to undergo the rescore process in response to a request from the Philippines Games and Amusements Board, a governmental body.
