The "Money Man" came through again.

The Floyd Mayweather Jr. - Victor Ortiz welterweight fight in September generated 1.25 million pay-per-view buys and grossed $78, 440,000, HBO announced on Friday.

It's the second highest grossing non-heavyweight event of all time. Mayweather, who scored a controversial fourth-round knockout of Ortiz, has been apart of the three highest grossing non-heavyweight events of all time.

His fight with Oscar de la Hoya in 2007 earned $136, 853,700 and his bout with Shane Mosley in 2010 garnered $78,330,000.

The Mayweather-de la Hoya bout generated a record 2.44 million PPV buys.

The question is when will Mayweather and Manny Pacquiao fight. Assuming they do, the purse would be enormous. Industry insiders speculate the fight would generate over three million PPV buys more than $500 in TV and gate revenue.

"My motto is 'hard work and dedication' and I have shown this throughout my entire career, which has allowed me to go out and perform each time I step in the ring," Mayweather said. "I give the fans everything I have with the best competition and exciting fights. I must be doing something right as they keep buying my fights and I appreciate their tremendous support. It feels good to be able to generate such a great interest in the sport."
