Floyd Mayweather, Jr.'s recent controversial victory earned through an unsportsmanlike manner makes Manny Pacquiao fare better in performance inside the ring, Filipino boxing analyst Al Mendoza said in an interview.

"I have two views about Mayweather. One, he did not violate any rule. The fight was on so his intention was to knock out his opponent. What he violated is the rule of being a sportsman," AP quoted Mendoza as saying.

"How can you beat someone who was not even protecting himself? Ortiz was not even looking. He is no gentleman," Mendoza continued.

Mendoza compared Mayweather and Pacman in their previous boxing performances.

In the decisive fourth round in the Mayweather-Ortiz bout held on Monday, Sep. 19, Victor Ortiz pinned Mayweather against the ropes but gave him a headbutt resulting in a point deducted from Ortiz.

But after Ortiz apologized to Mayweather, he was knocked out by the latter's 1-2 punch that also rendered the spectators, judges, and referee Joe Cortez stunned.

In Pacman's World Boxing Council boxing match with lightweight champion David Diaz on June 2008, Pacquiao tried to help Diaz when the latter was knocked down.

"Helping up an opponent is disallowed but Pacquiao forgot it because he is a gentleman at heart. When he beat up Antonio Margarito, he wanted the referee to end the fight. He even said: 'Boxing is not about killing.' Unfortunately, I don't think Mayweather can use that line," AP reported Mendoza concluding the interview.
