An administrative error on the scorecard used in Floyd Mayweather's victory over Manny Pacquiao has ignited conspiracy theorists into suggesting the Filipino should have won the bout.

Judges Glenn Feldman, Burt Clements and Dave Moretti, named 'white', 'blue' and 'pink' on the scorecard respectively, all award Mayweather victory on the night but in every column where they mark their scores at the end of the round, he is labelled as being in the red corner.

This is the point that has galvanised certain boxing fans into suggesting the fight may have been awarded to the wrong fighter because Mayweather was actually in the blue corner in Las Vegas. It was Pacquiao who took red.

It is very unlikely to be anything more than human error but conspiracy theorists will allege there was something sinister at hand, though there is no evidence of any intentional wrongdoing on the part of the judges

The bottom right of the scorecard, issued by the Nevada State Athletic Commission, has 'Mayweather won by unanimous decision' written underneath Moretti's name.

Evader Holyfield was among those questioning the decision of the judges, saying 'I thought Pacquiao won a poor fight.'

And several people also took to social media to question the eventual decision. As well as a whole thread about the 'conspricy' starting on Reddit, Twitter user ‏'@OperationSyaf' posted (sic): 'Fight of the century? Scam of the century. (Pacquiao is in the red corner and Mayweather in the blue; reversed scores)'

@LiamFellows added: Pacquiao was in the red corner and Mayweather was in Blue? They've basically robbed Pacquiao of the win he deserved.

And @GoonerMarty is another of many who questioned the marks: 'Interesting, Pacquiao RED corner, Mayweather BLUE, judges appear to have scored in favour of Pac Man'

It was Pacquiao who occupied the red corner, different to what was marked on the official scorecard

Feldman and Clements gave the blue corner victory by 116-112, with Moretti marking the margin of triumph slightly greater at 118-110.

Mayweather extended his impressive unbeaten career record to 48-0 by defeating Pacquiao.

Moretti only gave the red corner two rounds - the fourth and the sixth - while Clements and Feldmen also gave the ninth and 10th to what seemed to be the 38-year-old fighter.

Sportsmail's Jeff Powell, meanwhile, had Pacquiao 4-2 up after six, giving him the early advantage.

Mayweather made most of the ground up in rounds seven to nine in Powell's eyes, while he also impressed in the closing rounds as his opponent tired.

Mayweather also had the edge when it came to the punch stats, outlanding Pacquiao with his jabs and power punches.
